Physical Exam of the Skin for Skin Cancer
During a physical exam for a skin problem, your doctor will examine the skin over your whole body, looking for suspicious growths, moles, or lesions. The exam is done using a bright light and sometimes a magnifying lens. The scalp is examined by parting the hair.

What To Think About
Photographs may be used to document and detect changes in the skin, especially atypical moles. Some medical centers use computers to compare photographs taken at an earlier exam with new photographs of suspicious moles and lesions. This technique may more accurately determine whether a mole or lesion is changing.
Doctors don't have to do a biopsy to see if a lesion is benign (noncancerous). They may use a dermatoscope to see spots on the skin. This tool's special magnifying lens and light source help the doctor see the skin more clearly. Also, with a method called confocal laser scanning microscopy (CLSM), doctors can look even more closely at changes in the cells and tissue of the skin.
Some experts think it's a good idea to check your own skin every month and have your doctor check periodically. People who are at risk for skin cancer or those who are over 40 years old may want to have their doctor check their skin every year. If you have already had skin cancer, your doctor will recommend more frequent exams.
