Your doctor can screen you for skin cancer if you start to show symptoms. The first step is to perform a basic skin exam, where your skin will be checked for bumps or spots that may be cancerous. If a suspicious area is found, a biopsy will be performed. This is done by taking a small portion of your skin and examining it under a microscope to look for signs of cancer. If the biopsy results are positive Dr. Cohen will advise you on the best way to proceed with your treatment.
