HOW IS MERKEL CELL CARCINOMA DIAGNOSED?

The first step to a diagnosis includes a physical exam, examination of health history, a skin exam, or a referral to a dermatologist or other skin specialist. If merkel cell carcinoma (MCC) is suspected, a skin biopsy will be completed (the removal of skin cells or tissue to be viewed by a pathologist). Options of skin biopsies include; shave, punch, incisional, or excisional biopsy. 

Findings from the diagnostic tests are then used to determine the stage of the cancer, which helps to establish treatment plans and prognosis.
