Merkel cell carcinoma is a rare, but deadly skin cancer that most commonly affects fair-skinned individuals over the age of 50. Those with weakened immune systems are also at risk. Excess UV exposure is another risk factor for this condition. Merkel cell cancers are hard, painless growths that are flesh-colored, red, or blue. The average size upon diagnoses is about three-quarters of an inch in diameter, but the tumors can grow to be 2 inches or more in diameter. Merkel cell cancers frequently spread, or metastasize, to lymph nodes or other parts of the body -- even when they are small.
