Skin cancer is the abnormal growth of cells in the skin. It is the most common type of cancer. It is almost always cured when it is found early and treated. So it is important to see your doctor if you have changes in your skin.
Skin cancer is named by the cell type from which it comes. Melanoma, for instance, originates from melanocyte cells, which make melanin in skin. This is the most serious type of skin cancer.
More common skin cancers are nonmelanomas, which are highly curable and slow-growing. The two main types are basal cell carcinoma and squamous cell carcinoma.
There are other types of skin cancer that are not melanoma. But these are much less common. They include Merkel cell carcinoma and several kinds of sarcomas.
Any change in the shape, size or color of a mole or birthmark can be a sign of skin cancer.
Skin cancers may grow in a mole or birthmark that you already have but may also grow in unmarked skin. They can be found anywhere on your body. Most of the time, they are on the upper back in men and women and on the legs of women.
Unlike a normal mole or mark, a melanoma or nonmelanoma can:
Both melanoma and nonmelanoma skin cancer is usually caused by too much exposure to the sun or tanning beds and sunlamps. This kind of exposure causes normal skin cells to become abnormal. These abnormal cells quickly grow out of control and attack the tissues around them.
Risk factors include:
Other things in your family background can increase your chances of getting the disease. For example, you may have abnormal, or atypical, moles. Atypical moles may fade into the skin and have a flat part that is level with the skin. They may be smooth or slightly scaly, or they may look rough and "pebbly."
The best ways to prevent all kinds of skin cancer include:
Check your skin every month for odd marks, moles or sores that will not heal. Pay extra attention to areas that get a lot of sun, such as your hands, arms and back. Ask your doctor to check your skin during regular physical exams or at least once a year.
Your doctor will check your skin to look for abnormal moles or growths. If your doctor thinks you have skin cancer, he or she will use a biopsy to find out if you have skin cancer. This means taking a sample of the growth and sending it to a lab to see if it contains cancer cells.
Other techniques may include total-body photography to monitor for changes in any mole and to watch for new moles appearing in normal skin. A series of photos of the suspicious lesions may be taken. Then the photos can be used as a baseline to compare with follow-up photos.
For certain types of skin cancer, a complete medical history and a physical exam are needed to find out whether the cancer has spread (metastasized) to other parts of the body. Imaging tests, including positron emission tomography (PET scan), computed tomography (CT scan) or magnetic resonance imaging (MRI), may be used to identify metastases in other parts of the body, such as the lymph nodes, lungs, brain, liver or other organs.
Melanoma has a complex system of staging that includes:
The most common treatment for any type of skin cancer is surgery. The most common way is to numb your skin so that it does not hurt, then cut out the cancer. You will be awake while this is done. That may be all the treatment that you may need for early-stage melanomas that have not spread to other parts of your body and nonmelanomas.
In more advanced stages, melanoma may spread, or metastasize, to other organs and bones, requiring additional treatment such as radiation, chemotherapy or immunotherapy.
Types of surgery for melanoma include:
After your treatment, you will need regular checkups because having skin cancer once means you are more likely to get it again.
