Merkel Cell Carcinoma (MCC) is a rare skin/neuroendocrine cancer. MCC is about 40 times more rare than melanoma and three times more deadly. It is distinctly lonely and scary to have. Most people, including many doctors, have never heard of it. Finding the most knowledgeable medical resources for diagnosis and treatment is essential. Getting the support of others who are also coping with MCC can be a helpful way of feeling less isolated.
