What is cancer?
|
Cancer
is a collection of more than 200 diseases, all of which share one common trait:
the uncontrolled growth and spread of abnormal cells. There are several kinds
of cancer, including:
· Carcinomas form in cells that cover the skin or line the mouth, throat, lungs and organs
· Sarcomas are found in the bones, muscles, fibrous tissues and some organs
· Leukemias arise from white blood cells in the blood or bone marrow
· Lymphomas originate in the lymphocyte cells (white blood cells that help fight infection) found in the blood, spleen and lymph nodes
What causes cancer?
|
The
more we can learn about what causes cancer, the more likely we are to find ways
to prevent it. In the laboratory, scientists explore possible causes of cancer
and try to determine exactly what happens in cells when they become cancerous.
Researchers also study patterns of cancer in the population to look for risk
factors, conditions that increase the chance that cancer might occur. They also
look for protective factors, things that decrease the risk.
Even
though doctors can seldom explain why one person gets cancer and another does
not, it is clear that cancer is not caused by an injury, such as a bump or
bruise. In addition, although being infected with certain viruses may increase
the risk of some types of cancer, cancer is not contagious; no one can
"catch" cancer from another person.
Cancer
develops over time. It is a result of a complex mix of factors related to
lifestyle, heredity, and environment. A number of factors that increase a
person's chance of developing cancer have been identified. Many types of cancer
are related to the use of tobacco, what people eat and drink, exposure to
ultraviolet (UV) radiation from the sun, and, to a lesser extent, exposure to
cancer-causing agents (carcinogens) in the environment and the workplace. Some
people are more sensitive than others are to factors that can cause cancer.
Still,
most people who get cancer have none of the known risk factors. In addition,
most people who do have risk factors do not get the disease.
Some
cancer risk factors can be avoided. Others, such as inherited factors, are
unavoidable, but it may be helpful to be aware of them. People can help protect
themselves by avoiding known risk factors whenever possible.
What are the risk factors
associated with cancer?
|
· Tobacco
· Diet
· Ultraviolet radiation
· Alcohol
· Ionizing radiation
· Chemicals and other substances
· Hormone replacement therapy (HRT)
· Diethylstilbestrol (DES)
· Close relatives with certain types of cancer
How are the various
cancers named?
|
Medical
professionals frequently refer to cancers based on their histological type.
However, the public is more familiar with cancer names based on their primary
sites. The most common sites in which cancer develops include the skin, lungs,
female breasts, prostate, colon and rectum, cervix and uterus.
Compared
with those based on histological type, cancers named after the primary site may
not be as accurate. Take lung cancer for example; the name does not specify the
type of tissue involved. It simply indicates where the cancer is located. In
fact, depending on how the cells look under a microscope, there are two major
types of lung cancer: non-small cell lung cancer and small cell lung cancer.
Non-small cell lung cancer can be further divided into various types named for
the type of cells in which the cancer develops, typically: squamous cell
carcinoma, adenocarcinoma, and large cell carcinoma.
However,
it's important to know that cancer can be classified by either the cell type or
its primary site. Saying that a woman has uterine carcinoma or uterine cancer
is the same thing as saying that she has cancer (or carcinoma) of the uterus.
How are breast cancers
named?
|
The
first determination for naming is whether the breast cancer is "in
situ" or "invasive". In situ cancers remain within the
boundaries of the kind of cells that formed them. In situ means in place
staying where it belongs and not spreading. For this reason in situ cancers are
sometimes called precancerous, meaning they may develop into invasive cancers
later. About 20-40% of in situ cancers will do this if not removed. Currently,
about 12% of detected breast cancers are in situ. This percentage is increasing
because breast cancers found on mammograms are often in situ. The other breast
cancers are all invasive cancers. Invasive cancers have broken out of the
boundaries of the group of cells they came from and are invading or growing
into the nearby breast tissue.
The second
part of the name tells something about that particular kind of cancer. Some
breast cancers get their names from the cells of the breast that turned into
cancer. If the cancer arises from the cells of the tubes or ducts that normally
carry milk to the nipple, it is called "ductal" or from the ducts.
Eighty percent of breast cancers are ductal. If a cancer arises from the part
of the breast that produces milk, it is called a lobular cancer.
"Lobular" refers to lobes, or the milk producing structures. Ten
percent of breast cancers are lobular. Another cancer type is inflammatory
breast cancer (3%), which causes the breast to look like it has an infection.
The names of other uncommon forms describe what the pathologist sees when s/he
looks at the cancer under the microscope. For example, tubular breast cancer
forms tube-like structures, medullary breast cancer has the color of the part
of the brain called the medulla, mucinous cancers contain mucus-like material,
and papillary cancer has finger-like projections.
Cancer terminology: the
language of cancer
|
The
ways in which cancers are named can convey a good deal of information about
them. However, their designations often have to be "decoded." As is
generally the case with medical terms, the "language" of cancer is
made up of compound words that contain a root, a prefix, and a suffix; the
common ones can be found here.
Specific
cancers may be named in multiple ways. One of the ways is to describe the
tissue type involved, cell type involved, or site of origin. Cancers are also
classified as to whether they are benign or malignant and by their clinical
stage.
Classifying cancer by type
of tissue
|
Carcinoma
A
neoplasm (literally "new growth"-that is, a cancer or tumor)
occurring in the epithelial cells that line organs and cover the surface of the
body (~ 90% of all cancers fit into this category)
Sarcoma
A
solid tumor occurring in connective tissue, muscle, and bone (~ 2% of all
cancers)
Leukemia
or lymphoma
A
neoplasm occurring in the circulatory (leukemia) or lymphatic (lymphoma)
systems (~ 8% of all cancers)
The
embryonic origin of these tissues led to these categories:
· ectoderm (outer layer of cells), from which the skin and nervous system are derived, is the usual source of a carcinoma
· mesoderm (middle layer of cells), from which bone, muscle, and blood are derived, is the usual source of a sarcoma, leukemia, or lymphoma
· endoderm (inner layer of cells), from which the lining of internal organs is derived, may also be the source of a carcinoma
Connection
to the embryonic nature of some tumors has led to two cancer-related terms:
Blastoma
("immature tumor")
A
neoplasm that resembles embryonic tissue
Teratoma
A
neoplasm that arose in tissues derived from all three embryonic germ layers
(ectoderm, mesoderm, and endoderm)
Classifying cancer by type
of cell
|
Tumors
may be identified by the type of cell within a tissue or organ that has
transformed into a cancer:
· Adenomatous cells-ductal or glandular cells
· Squamous cells-flat cells
· Myeloid-blood cell
· Lymphoid-lymphocytes or macrophages
Classifying by site of the
tumor's origin
|
The
name of a cancer may first designate the site in the body where the neoplasm
originated and then indicate the type of tissue in which it has occurred, the
cell type, and/or the founder's name, or some combination of these terms. The
following are some examples:
· Breast-breast carcinoma of ductal, medullary, papillary, etc, cells
· Bone-osteosarcoma, Ewing's sarcoma
· Eye-retinoblastoma
· Lip, tongue, mouth, nasal cavity-squamous cell carcinoma
· Lymphocytes-acute lymphocytic leukemia, chronic lymphocytic leukemia, Hodgkin's lymphoma
· Prostate-adenocarcinoma
· Ovary-adenocarcinoma, choriocarcinoma, teratoma, Brenner tumor
Naming of benign or
malignant tumors
|
Benign
tumors are not cancer. They can often be removed and, in most cases, they do
not come back. Cells from benign tumors do not spread to other parts of the
body. Most important, benign tumors are rarely a threat to life.
Benign
tumors:
· are generally slow growing and enclosed in a fibrous capsule
· are generally considered innocuous, although their location can make them serious, such as a tumor located in the brain, where removal by surgery poses serious risks
· are not considered cancerous (that is, they are not malignant)
· are given names that usually end in "oma" (Latin origin, indicates a swelling)(although a melanoma is a malignant skin cancer)
Malignant
tumors are cancer. Cells in these tumors are abnormal and divide without
control or order. They can invade and damage nearby tissues and organs.
Malignant
tumors:
· proliferate rapidly, invading neighboring tissues
· can metastasize, or spread, to other sites of the body
· are named using the conventions of tissue, cell type, and origin
A
tumor of the bone is an osteoma if benign and an osteosarcoma if malignant; a
tumor of nerve cells may be a ganglioneuroma if benign and a neuroblastoma if
malignant; a tumor of melanocytes are nevi if benign but a melanoma if
malignant.
Finally,
some neoplasms are named after the physician who first described them. These
designations may not convey as much information as other naming conventions do;
for example, Wilm's tumor, Hodgkin's lymphoma, and Kaposi's sarcoma.
