Merkel cell carcinoma: Overview
What is Merkel cell carcinoma?Merkel cell carcinoma (MCC) is a rare skin cancer. It is also an aggressive skin cancer. MCC is considered aggressive because it can:
- Grow quickly and spread.
- Return after treatment.
Because MCC is aggressive, doctors recommend prompt treatment. The sooner this skin cancer is treated the better the outcome. To improve a patient’s outcome, a team of doctors usually creates the treatment plan for MCC. This approach allows the patient to benefit from the expertise of specialists in different areas of medicine. The team often includes a dermatologist, a medical oncologist (cancer specialist), and a radiation oncologist (specialist in treating cancer with radiation.) Other doctors may also be a part of this team.
It is important for patients diagnosed with MCC to:
- Keep all appointments with their doctors.
- Check their skin and lymph nodes for signs of cancer as recommended.
These actions help find cancer as early as possible.
