As a person grows older and is exposed to sunlight, the skin changes in response to this exposure. Most people have some skin marks, such as freckles and moles, which may multiply or darken over time.

There are many kinds of lumps in the body’s soft tissues. Most lumps are not cancerous. Such noncancerous lumps include lipomas (benign fat collections), cysts (fluid-filled sacs), and hemangiomas (large collections of abnormal blood vessels).

The goal of surgery is to take out the cancer while preserving the function of the affected area.
