is a group of diseases involving abnormal cell growth with the potential
to invade or spread to other parts of the body. Not all tumors are
cancerous; benign tumors do not spread to other parts of the body.
Possible signs and symptoms include a lump, abnormal bleeding, prolonged
cough, unexplained weight loss and a change in bowel movements. While
these symptoms may indicate cancer, they may have other causes. Over 100

spread of a cancer or other disease from one organ or part of the body to
another without being directly connected with it. The new occurrences of
disease thus generated are referred to as metastases (mets). Cancer occurs
after a single cell in a tissue is progressively genetically damaged to
produce cells with uncontrolled proliferation. This uncontrolled
proliferation by mitosis produces a primary heterogeneic tumour. The cells
which constitute the tumor eventually undergo metaplasia, followed by
dysplasia then anaplasia, resulting in a malignant phenotype. This
malignancy allows for invasion into the circulation, followed by invasion
to a second site for tumorigenesis.
is the formation of a cancer, whereby normal
cells are transformed into cancer cells. The process is characterized by
changes at the cellular, genetic, and epigenetic levels and abnormal cell
division, in some cancers forming a malignant mass. Cell division is a
physiological process that occurs in almost all tissues and under many
circumstances. Under normal circumstances, the balance between
proliferation and programmed cell death

is maintained by regulation of both processes to ensure the integrity of
tissues and organs.

include descriptive, analytical, biochemical, and molecular epidemiology,
the use of biomarkers to study the neoplastic and preneoplastic
processes in humans, chemoprevention and other types of prevention trials,
and the role of behavioral factors in cancer etiology and prevention.
Epidemiology of Cancer

as a way to infer possible trends and causes. The study of cancer
epidemiology uses epidemiological methods to find the cause of cancer and
to identify and develop improved treatments. This area of study must
contend with problems of
lead time bias and length time bias
Tumor Suppressor Gene
is a gene that protects a cell from one step on
the path to cancer. When this gene mutates to cause a loss or
reduction in its function, the cell can progress to cancer, usually in
combination with other genetic changes. The loss of these genes may be
even more important than proto-oncogene/oncogene activation for the
formation of many kinds of human cancer cells. Tumor suppressor genes can
be grouped into categories including caretaker genes, gatekeeper genes,
and landscaper genes; the classification schemes are evolving as medicine
advances, learning from fields including molecular biology, genetics, and
encode products that stabilize the genome.
Fundamentally, mutations in caretaker genes lead to genomic instability.
Tumor cells arise from two distinct classes of genomic instability:
mutational instability arising from changes in the nucleotide sequence of
DNA and chromosomal instability arising from improper rearrangement of
. In contrast to caretaker genes, gatekeeper genes encode gene
products that act to prevent growth of potential cancer cells and prevent
accumulation of mutations that directly lead to increased cellular
proliferation. The third classification of genes, the landscapers, encode
products that, when mutated, contribute to the neoplastic growth of cells
by fostering a stromal environment conducive to unregulated cell
is a collection of processes by which a cell identifies and
corrects damage to the DNA molecules that encode its genome. In human
cells, both normal metabolic activities and environmental factors such as
radiation can cause DNA damage, resulting in as many as 1 million
individual molecular lesions per cell per day. Many of these lesions cause
structural damage to the DNA molecule and can alter or eliminate the
cell's ability to transcribe the gene that the affected DNA
lesions induce potentially harmful mutations in the cell's genome, which
affect the survival of its daughter cells after it undergoes mitosis. As a
consequence, the DNA repair process is constantly active as it responds to
damage in the DNA structure. When normal repair processes fail, and when
cellular apoptosis does not occur, irreparable DNA damage may occur,
including double-strand breaks and DNA crosslinkages (interstrand
crosslinks or ICLs). This can eventually lead to malignant tumors, or
cancer as per the two hit hypothesis. The rate of DNA repair is dependent
on many factors, including the cell type, the age of the cell, and the
extracellular environment. A cell that has accumulated a large amount of
DNA damage, or one that no longer effectively repairs damage incurred to
its DNA, can enter one of three possible states: An irreversible state of
dormancy, known as senescence. Cell suicide
also known as apoptosis or programmed cell death. Unregulated cell
division, which can lead to the formation of a tumor that is cancerous.
The DNA repair ability of a cell is vital to the integrity of its genome
and thus to the normal functionality of that organism. Many genes that
were initially shown to influence life span have turned out to be involved
in DNA damage repair and protection.
any isoform of a protein encoded by homologous genes in various organisms,
such as TP53 (humans) and Trp53 (mice). This homolog (originally thought
to be, and often spoken of as, a single protein) is crucial in
multicellular organisms, where it prevents cancer formation, thus,
functions as a tumor suppressor. As such, p53 has been described as "the
guardian of the genome" because of its role in conserving stability by
preventing genome mutation. Hence TP53 is classified as a tumor
suppressor gene.(Italics are used to denote the TP53 gene name and
distinguish it from the protein it encodes).

Bone Morphogenetic Protein
are a group of growth factors also known as
cytokines and as metabologens. Originally discovered by their ability to
induce the formation of bone and cartilage, BMPs are now considered to
constitute a group of pivotal morphogenetic signals, orchestrating tissue
architecture throughout the body. The important functioning of BMP signals
in physiology is emphasized by the multitude of roles for dysregulated BMP
signaling in pathological processes. Cancerous disease often involves
misregulation of the BMP signaling system. Absence of BMP signaling is,
for instance, an important factor in the progression of colon cancer, and
conversely, over activation of BMP signaling following reflux-induced
esophagitis provokes Barrett's esophagus and is thus instrumental in the
development of adenocarcinoma in the proximal portion of the
gastrointestinal tract.A signaling pathway

is a person with cancer of any type who is
still living. Whether a person becomes a survivor at the time of diagnosis
or after completing treatment, whether people who are actively dying are
considered survivors, and whether healthy friends and family members of
the cancer patient are also considered survivors, varies from group to
group. Some people who have been diagnosed with cancer reject the term
survivor or disagree with some definitions of it. How many people are
cancer survivors depends on the definition used. About 11 million
Americans alive today—one in 30 people–are either currently undergoing
treatment for cancer or have done so in the past. Currently nearly 65% of
adults diagnosed with cancer in the developed world are expected to live
at least five years after the cancer is discovered.

classified as suppression immunotherapies. Immunomodulatory regimens often
have fewer side effects than existing drugs, including less potential for
creating resistance when treating microbial disease. Cell-based
immunotherapies are effective for some cancers. Immune effector cells such
as lymphocytes, macrophages, dendritic cells, natural killer cells (NK
Cell), cytotoxic T lymphocytes (CTL), etc., work together to defend the
body against cancer by targeting abnormal antigens expressed on the
surface of tumor cells. Therapies such as granulocyte colony-stimulating

sent to a manufacturing center where they are genetically modified to
include a new gene that contains a specific protein (a
chimeric antigen receptor or CAR

Adaptive Immune System
is a subsystem of
the overall immune system that is composed of highly specialized, systemic
cells and processes that eliminate pathogens or prevent their growth. The
adaptive immune system is one of the two main immunity strategies found in
vertebrates (the other being the innate immune system). Adaptive immunity
creates immunological memory after an initial response to a specific
pathogen, and leads to an enhanced response to subsequent encounters with
that pathogen. This process of acquired immunity is the basis of
vaccination. Like the innate system, the adaptive system includes both
humoral immunity components and cell-mediated immunity components.

is the immunological response originating from immune system activation by
antigens, including immunity to pathogenic microorganisms and its
products, as well as autoimmunity to self-antigens allergies, and graft
ejections. In this process main cells involved are the T cells, B cells of
lymphocytes, and macrophagea. These cells produce lymphokines that
influence the other host cells activities. B cells mature to produce
immunoglobulins or antibodies, that react with antigens. At same time,
macrophages are processing the antigens into immunogenic units which

desmosomes, components of the skin that function to keep certain layers of
skin bound to each other. As desmosomes are attacked, the layers of skin
separate and the clinical picture resembles a blister. Over time the

is a molecule capable of inducing an immune response on the part of the
host organism, though sometimes antigens can be part of the host itself.
In other words, an antigen is any substance that causes an immune system
to produce antibodies against it. Each antibody is specifically produced
by the immune system to match an antigen after cells in the immune system
come into contact with it; this allows a precise identification of the
antigen and the initiation of a tailored response. The antibody is said to
"match" the antigen in the sense that it can bind to it thanks to
adaptations performed to a region of the antibody; because of this, many
different antibodies can be produced, with specificity to bind many
different antigens while sharing the same basic structure. In most cases,
an antibody can only bind one specific antigen; in some instances,
however, antibodies may bind more than one antigen.

cells (also called tumors or malignancies). It is a field of research that
aims to discover cancer immunotherapies to treat and retard progression of
the disease. The immune response, including the recognition of
cancer-specific antigens, forms the basis of targeted therapy (such as
vaccines and antibody therapies) and tumor marker-based diagnostic tests.
How to Help our Immune Cells to Recognize
What the Sugar Coating on your Cells is trying to tell you
is a generic term for the N- or O-substituted derivatives of
neuraminic acid, a monosaccharide with a nine-carbon backbone. It is also
the name for the most common member of this group, N-acetylneuraminic acid
(Neu5Ac or NANA). Sialic acids are found widely distributed in animal
tissues and to a lesser extent in other organisms, ranging from plants and
fungi to yeasts and bacteria, mostly in glycoproteins and gangliosides
(they occur at the end of sugar chains connected
to the surfaces of cells
) In humans the brain has the highest sialic acid concentration,
where these acids play an important role in
ganglioside structure in synaptogenesis. In general, the amino group bears
either an acetyl or a glycolyl group, but other modifications have been
described. These modifications along with linkages have shown to be tissue
specific and developmentally regulated expressions, so some of them are
only found on certain types of glycoconjugates in specific cells. The
hydroxyl substituents may vary considerably; acetyl, lactyl, methyl,
sulfate, and phosphate groups have been found.
Discovery of Brain-like activity in immune system promises better disease
. Human immune cells contain particles that have
neurotransmitters including dopamine, which plays a crucial role in immune
responses. Neurons rely on synaptic interactions and neurotransmitters
such as dopamine, which are small molecules transmitted across synapses to
deliver signals from one cell to another that play a major role in
reward-motivated behaviour. Like neurons, specialised T cells transfer
to B cells

to produce the

is a large, Y-shaped protein
produced mainly by plasma cells that is used by the immune system to
neutralize pathogens such as bacteria and viruses. The antibody recognizes
a unique molecule of the harmful agent, called an antigen, via the Fab's
variable region. Each tip of the "Y" of an antibody contains a paratope
(analogous to a lock) that is specific for one particular epitope
(similarly analogous to a key) on an antigen, allowing these two
structures to bind together with precision. Using this binding mechanism,
an antibody can tag a microbe or an infected cell for attack by other
parts of the immune system, or can neutralize its target directly (for
example, by blocking a part of a microbe that is essential for its
invasion and survival). Depending on the antigen, the binding may impede
the biological process causing the disease or may activate macrophages to
destroy the foreign substance. The ability of an antibody to communicate
with the other components of the immune system is mediated via its Fc
region (located at the base of the "Y"), which contains a conserved
glycosylation site involved in these interactions. The production of
antibodies is the main function of the humoral immune system. Also known
as an immunoglobulin (Ig), Antibodies are secreted by B cells of the
adaptive immune system, mostly by differentiated B cells called plasma
cells. Antibodies can occur in two physical forms, a soluble form that is
secreted from the cell to be free in the blood plasma, and a
membrane-bound form that is attached to the surface of a B cell and is
referred to as the B-cell receptor (BCR). The BCR is found only on the
surface of B cells and facilitates the activation of these cells and their
subsequent differentiation into either antibody factories called plasma
cells or memory B cells that will survive in the body and remember that
same antigen so the B cells can respond faster upon future exposure. In
most cases, interaction of the B cell with a T helper cell is necessary to
produce full activation of the B cell and, therefore, antibody generation
following antigen binding. Soluble antibodies are released into the blood
and tissue fluids, as well as many secretions to continue to survey for
invading microorganisms. Antibodies are glycoproteins belonging to the
immunoglobulin superfamily. They constitute most of the gamma globulin
fraction of the blood proteins. They are typically made of basic
structural units—each with two large heavy chains and two small light
chains. There are several different types of antibody heavy chains that
define the five different types of crystallisable fragments (Fc) that may
be attached to the antigen-binding fragments. The five different types of
Fc regions allow antibodies to be grouped into five isotypes. Each Fc
region of a particular antibody isotype is able to bind to its specific Fc
Receptor (except for IgD, which is essentially the BCR), thus allowing the
antigen-antibody complex to mediate different roles depending on which FcR
it binds. The ability of an antibody to bind to its corresponding FcR is
further modulated by the structure of the glycan(s) present at conserved
sites within its Fc region. The ability of antibodies to bind to FcRs
helps to direct the appropriate immune response for each different type of
foreign object they encounter. For example, IgE is responsible for an
allergic response consisting of mast cell degranulation and histamine
release. IgE's Fab paratope binds to allergic antigen, for example house
dust mite particles, while its Fc region binds to Fc receptor ε. The
allergen-IgE-FcRε interaction mediates allergic signal transduction to
induce conditions such as asthma. Though the general structure of all
antibodies is very similar, a small region at the tip of the protein is
extremely variable, allowing millions of antibodies with slightly
different tip structures, or antigen-binding sites, to exist. This region
is known as the hypervariable region. Each of these variants can bind to a
different antigen. This enormous diversity of antibody paratopes on the
antigen-binding fragments allows the immune system to recognize an equally
wide variety of antigens. The large and diverse population of antibody
paratope is generated by random recombination events of a set of gene
segments that encode different antigen-binding sites (or paratopes),
followed by random mutations in this area of the antibody gene, which
create further diversity. This recombinational process that produces
clonal antibody paratope diversity is called V(D)J or VJ recombination.
Basically, the antibody paratope is polygenic, made up of three genes, V,
D, and J. Each paratope locus is also polymorphic, such that during
antibody production, one allele of V, one of D, and one of J is chosen.
These gene segments are then joined together using random genetic
recombination to produce the paratope. The regions where the genes are
randomly recombined together is the hyper variable region used to
recognise different antigens on a clonal basis. Antibody genes also
re-organize in a process called class switching that changes the one type
of heavy chain Fc fragment to another, creating a different isotype of the
antibody that retains the antigen-specific variable region. This allows a
single antibody to be used by different types of Fc receptors, expressed
on different parts of the immune system.

Memory B Cell
are a B cell sub-type that
are formed within germinal centers following primary infection and are
important in generating an accelerated and more robust antibody-mediated
immune response in the case of re-infection (also known as a secondary
immune response).T Cell
is a type of lymphocyte (a subtype of white blood cell) that plays a
central role in cell-mediated immunity. T cells can be distinguished from
other lymphocytes, such as B cells and natural killer cells, by the
presence of a T-cell receptor on the cell surface. They are called T cells
because they mature in the thymus from thymocytes (although some also
mature in the tonsils). The several subsets of T cells each have a
distinct function. The majority of human T cells rearrange their alpha and
beta chains on the cell receptor and are termed alpha beta T cells (αβ T
cells) and are part of the adaptive immune system. Specialized gamma delta
T cells, (a small minority of T cells in the human body, more frequent in
ruminants), have invariant T cell receptors with limited diversity, that
can effectively present antigens to other T cells and are considered to be
part of the innate immune system.

applied. Such T cells can recognize foreign invaders, such as bacteria or
viruses, as well as cancer cells. Memory T cells have become "experienced"
by having encountered antigen during a prior infection, encounter with
cancer, or previous vaccination. At a second encounter with the invader,
memory T cells can reproduce to mount a faster and stronger immune
response than the first time the immune system responded to the invader.
This behavior is utilized in T lymphocyte proliferation assays, which can
reveal exposure to specific antigens

Cytotoxic T Cell
is a T lymphocyte (a
type of white blood cell) that kills cancer cells
cells that are infected (particularly with viruses), or cells that are
damaged in other ways.
T Helper Cell
are a type of T cell that play an important role in the immune system,
particularly in the adaptive immune system. They help the activity of
other immune cells by releasing T cell cytokines. These cells help
suppress or regulate immune responses. They are essential in B cell
antibody class switching, in the activation and growth of cytotoxic T
cells, and in maximizing bactericidal activity of phagocytes such as
Sunlight Energizes Infection Fighting T
is a specialized primary lymphoid organ of the immune system. Within the
thymus, T cells or T lymphocytes mature. T cells are critical to the
adaptive immune system, where the body adapts specifically to foreign
invaders. The thymus is composed of two identical lobes and is located
anatomically in the anterior superior mediastinum, in front of the heart
and behind the sternum.
are a type of cytotoxic lymphocyte critical to the innate immune
system. The role NK cells play is analogous to that of cytotoxic T cells
in the vertebrate adaptive immune response. NK cells provide rapid
responses to viral-infected cells, acting at around 3 days after
infection, and respond to tumor formation. Typically, immune
detect major histocompatibility
complex (MHC) presented on infected cell surfaces, triggering cytokine
release, causing lysis or apoptosis. NK cells are unique, however, as they
have the ability to recognize stressed cells in the absence of antibodies
and MHC, allowing for a much faster immune reaction. They were named
"natural killers" because of the initial notion that they do not require
activation to kill cells that are missing "self" markers of MHC class 1.
This role is especially important because harmful cells that are missing
MHC I markers cannot be detected and destroyed by other immune cells, such
as T lymphocyte cells.
Killer T Cell
are a heterogeneous group of T cells that share
properties of both T cells and natural killer cells. Many of these
cells recognize the non-polymorphic CD1d molecule, an antigen-presenting
molecule that binds self and foreign lipids and glycolipids. They
constitute only approximately 0.1% of all peripheral blood T cells.
Natural killer T cells should not be confused with natural killer cells.

is the physiological
process through which new blood vessels form from pre-existing vessels. In
precise usage this is distinct from vasculogenesis, which is the de novo
formation of endothelial cells from mesoderm cell precursors, and from
neovascularization, although discussions are not always precise
(especially in older texts). The first vessels in the developing embryo
form through vasculogenesis, after which angiogenesis is responsible for
most, if not all, blood vessel growth during development and in disease.
Angiogenesis is a normal and vital process in growth and development, as
well as in wound healing and in the formation of granulation tissue.
However, it is also a fundamental step in the transition of tumors from a
benign state to a malignant one, leading to the use of angiogenesis
inhibitors in the treatment of cancer. The essential role of angiogenesis
in tumor growth was first proposed in 1971 by Judah Folkman, who described
tumors as "hot and bloody," illustrating that, at least for many tumor
types, flush perfusion and even hyperemia are characteristic.

As transducers of patterns of variability in the surrounding environment,
carotid and aortic bodies count as ‘sensors’ in a similar way as taste
buds and photoreceptors. However, because carotid and aortic bodies detect
variation within the body’s internal organs, they are considered
interoceptors. Taste buds, olfactory bulbs, photoreceptors, and other
receptors associated with the five traditional sensory modalities, by
contrast, are exteroceptors in that they respond to stimuli outside the
body. The body also contains proprioceptors, which respond to the amount
of stretch within the organ, usually muscle, that they occupy.
