Is a type of skin cancer but not the deadliest but rare and aggressive, form of skin cancer.
* It begins in Merkel cells, which are found in the base of the epidermis.
* MCC usually appears as a red, painless lump in sun-exposed areas such as the neck, face, or head.
* People over 50 (most likely men) with a compromised immune system are at higher risk of developing this type of skin cancer.
*Merkel cell carcinoma tends to grow rapidly and spread quickly to other parts of the body.
* Treatment options for MCC depend on whether it has spread.
