Merkel cell carcinoma (MCC) is a rare and aggressive type of skin cancer that can be life-threatening. It usually appears as a painless, flesh-colored, or bluish-red nodule on the skin, often on the face, head, or neck. Merkel cell carcinoma is also known as neuroendocrine carcinoma of the skin or trabecular cancer. It develops in Merkel cells, which are found in the top layer of the skin and are responsible for the sensation of touch.
Merkel cell carcinoma is primarily caused by long-term sun exposure and can also be associated with a weakened immune system. The cancer tends to grow quickly and spread early in its development. It often first spreads to nearby lymph nodes and then to distant parts of the body, such as the lungs, brain, bones, or other organs. Merkel cell carcinoma is the second most common cause of skin cancer death after melanoma.
Some common risk factors for Merkel cell carcinoma include:
- Long-term sun exposure
- Weakened immune system
- Fair skin
- Age over 50
Early detection is crucial for the successful treatment of Merkel cell carcinoma. Be watchful for any new or changing lesions on your skin, and if you have been treated for a previous MCC, pay close attention to the site and the surrounding region. If you notice any suspicious changes, contact your medical team immediately.
