Skin cancer is the most common form of cancer in the United States and involves abnormal growths of skin cells that can form anywhere on the body, but most frequently appear on skin that is exposed to the sun. There are more than a million new cases of skin cancer in the US each year. Although most cases of skin cancer can be successfully treated, it is still important to keep skin safe and healthy and try to prevent this disease.
There are three major types of skin cancer that affect associated layers of the skin. These major types are:
Everyday, skin cells die and new ones form to replace them in a process controlled by DNA. Skin cancer can form when this process does not work properly because of damage to DNA. New cells may form when they are not needed or older cells may not die. This can cause a growth of tissue known as a tumor. DNA damage is often a result of ultraviolet (UV) radiation from sunlight or tanning lamps. Since skin cancer can sometimes affect areas not exposed to the sun, heredity may also be a factor.
Certain factors, such as fair skin, moles, a weakened immune system and age, can also increase the risk of skin cancer.
Skin cancer can often be identified as a new or changed growth on the skin that may often occur on the scalp, face, lips, ears, neck, chest, arms, hands or legs. The appearance of the growth depends on the type of cancer, but can appear as:
It is important to see your doctor if you notice any skin changes. Early detection is valuable in successfully treating skin cancer. Regular full body screening is recommended as well. A biopsy is performed to properly diagnose suspected cancerous growths.
Treatment for skin cancer depends on the type, size and location of the tumor. Most options remove the entire growth and are usually effective. Removal procedures are usually simple and require only a local anesthetic in an outpatient setting. Some of the treatment options for skin cancer include:
Other treatment options are also available, including new methods that are currently being studied.
Although most treatment for skin cancer is successful, new tumors can still form. It is important to practice preventive measures and see your doctor on a regular basis. You can also perform self skin checks to spot any changes as soon as possible.
