Overview
Epidemiology
This type of cancer occurs mostly in -- though not restricted to -- Caucasians between 60 and 80 years of age. It occurs about twice as often in males as in females. There are roughly 1200 new cases diagnosed a year in the United States, compared to 60,000 new cases of melanoma and over 1 million new cases of nonmelanoma skin cancer. [1] Merkel cell cancer can be mistaken for another cancer like basal cell carcinoma, squamous cell carcinoma, malignant melanoma, lymphoma, small cell carcinoma or may appear to be a benign cyst. Researchers believe that exposure to sunlight or ultraviolet light may increase a person’s risk of this disease.
Immune suppression can profoundly increase one's risk of developing Merkel cell cancer. According to a recent study in the Lancet, Merkel cell carcinoma occurs 13.4 times more often in people with advanced HIV as compared to the general population. Solid organ transplant recipients have similarly increased risk.
