Melanoma Skin Cancer of U.S. Senator John McCain

 In August of 2000, U.S. senator and presumptive Republican presidential nominee John McCain was found to have a dangerous form of skin cancer, melanoma, for the second time. The
senator had a superficial (meaning less dangerous because it has not invaded deeply into the tissues) melanoma diagnosed in 1993. Melanoma is the most dangerous form of skin cancer and is frequently associated with prolonged exposure of the skin to sunlight.
The cancer identified in 2000, located on the left side of his face, had penetrated the skin more deeply than the superficial cancer removed in 1993. The cancer diagnosed in 2000 was removed by a surgical procedure that also included removal and examination of multiple lymph nodes to determine the extent of
the spread of the cancer. His staff reported at the time that there was no evidence of spread of the cancer. According to press reports, McCain has also had two more superficial melanomas removed since his surgery in 2000.
Melanoma can occur on any skin surface. In men, it is often found on the trunk (the area from the shoulders to the hips) or the head and neck. In women, melanoma often develops on the lower legs or the trunk. Melanoma is rare in people with deeply pigmented skin. When it does develop in dark-skinned people, it tends to occur under the fingernails or toenails, or on the palms
of the hands or soles of the feet. Melanoma affects people of all age groups, but the chance of developing this disease increases with age.

Introduction
Melanoma is a cancer that develops in melanocytes, the pigment cells
present in the skin.
It can be more serious than the other forms of skin cancer because it may spread
to other parts of the body (metastasize) and cause serious illness and death.
About 50,000 new cases of melanoma are diagnosed in the United States every
year.
Because most melanomas occur on the skin where they can be seen, patients
themselves are often the first to detect many melanomas. Early detection and
diagnosis are crucial. Caught early, most melanomas can be cured with relatively
minor surgery.
This article is written from the standpoint of the patient. In other words,
instead of describing the disease in exhaustive detail, I will try to help
answer the questions: "How do I know if I have melanoma?" and "Should I
should be checked for it?"
Spots on the skin
Guideline # 1: Nobody can diagnose him- or herself. If you see a spot that
looks as though it is new or changing, show it to a doctor. When it comes to
spots on the skin, it is always better to be safe than sorry.
Everybody gets spots on their skin. The older we are, the more spots we have.
Some of these are freckles, others are moles, and still others are made up of
collections of tissue, such as blood vessels or pigment cells. Most of these
spots are benign. That means they are neither cancerous nor on the way to
becoming cancerous.
Moles
Guideline # 2: The vast majority of moles stay as moles and do not turn into
anything else.
Some people are born with moles (the medical name is "nevus" plural "nevi").
Almost everyone develops them, starting in childhood. On the average, people
have about 25 moles, though some have fewer and others many more. Moles may be
flat or raised, and they may range in color from tan to light brown to black.

Defining cancer
Cancer is a term used for diseases in which abnormal cells divide without
control and are able to invade other tissues. Cancer cells can spread to
other parts of the body through the blood and lymph systems.
Cancer is not just one disease but many diseases. There are more than 100
different types of cancer. Most cancers are named for the organ or type of cell
in which they start -- for example, cancer that begins in the colon is called
colon cancer; cancer that begins in basal cells of the skin is called basal cell
carcinoma.
Cancer types can be grouped into broader categories. The main categories of
cancer include:
- Carcinoma - cancer that begins in the skin or in tissues that line or cover
internal organs.
- Sarcoma - cancer that begins in bone, cartilage, fat, muscle,
blood vessels, or other connective or supportive tissue.
- Leukemia - cancer that sta...
