How are people screened for melanoma?
Early detection and recognition of skin cancer are very important. Recognizing the early warning signs of melanoma and doing regular self-examinations of your skin can help find melanoma early, when the disease is more curable. Your doctor may also recommend screenings done by a health care professional and/or medical tests based on your risk factors and medical history.
Melanoma can appear anywhere on the body, even on areas that are not exposed to the sun. The most frequent locations for melanoma are the face, scalp, trunk or torso (chest, abdomen, back), legs, and arms. However, a subtype of melanoma called acral melanoma can develop under the fingernails or toenails, on the palms of hands or soles of feet, or on the tips of fingers and toes. Mucosal melanoma can develop on mucous membranes, such as skin that lines the mouth, nose, vagina, and anus.
Self-examinations should be performed in front of a full-length mirror in a brightly lit room. It helps to have another person check the scalp and back of the neck. Include the following steps in a self-examination:
Examine the front and back of the entire body in a mirror, then the right and left sides, with arms raised.
Bend the elbows and look carefully at the outer and inner forearms, upper arms (especially the hard-to-see back portion), and hands.
Look at the front, sides, and back of the legs and feet, including the soles and the spaces between the toes.
Part the hair to lift it and examine the back of the neck and scalp with a hand mirror.
Check the back, genital area, and buttocks with a hand mirror.
If you suspect that certain areas of skin are changing, take photos of the lesion(s) to look for changes over time.
Talk with your doctor or a dermatologist if your hairdresser or barber has noticed a suspicious skin area, or lesion, on your scalp or beard or if you find any of the following during a self-examination:
A growth on the skin that matches any symptom listed in Symptoms and Signs
New growth on the skin
A suspicious change in an existing mole or spot
A sore that does not heal within 2 weeks
Medical tests for early detection
A painless medical technique being used for early detection of melanoma is epiluminescence microscopy, or dermoscopy. Using a handheld device, a doctor can evaluate the patterns of size, shape, and pigmentation in pigmented skin lesions. Among trained, experienced medical professionals, dermoscopy may reduce the number of biopsies (see Diagnosis) of pigmented lesions to rule out melanoma, although more research is needed.
Confocal scanning laser microscopy is another new technology that may improve the examination of possible melanoma lesions. Currently, it is only used in research studies, called clinical trials, and is available in a few major medical centers.
