Facing Merkel cell carcinoma can be emotionally challenging—for both patients and caregivers. It’s normal to feel anxious, uncertain, or overwhelmed.
You're not alone. Support is available to help you manage the emotional side of diagnosis, treatment, and recovery. Whether you’re looking for mental health resources, caregiver tools, or simply want to hear from others who’ve been there, our Merkel Cell Community for patients and caregivers can offer guidance and connection every step of the way.
Merkel cell carcinoma often shows up as:
-
A painless, firm bump or nodule
-
Skin-colored, red, blue, or purple
-
Most often on sun-exposed areas like the face, neck, arms, or scalp
-
Grows quickly over weeks or months
-
Sometimes mistaken for a pimple, bug bite, or cyst
If you notice a new or changing bump, especially one that grows fast, don’t wait—get it checked.
-
Chronic unprotected exposure to UV radiation from the sun or tanning beds
Weakened immune system due to certain conditions or medications
Previous history of skin cancer, including basal cell carcinoma and squamous cell carcinoma
Over the Age of 50
Fair skin, light hair, and/or light eyes

Merkel cell carcinoma (MCC) is a rare, aggressive form of skin cancer with a high risk of coming back (recurring) and spreading to other parts of the body (metastasizing), often within two to three years after the first diagnosis.
Merkel cell carcinoma (MCC) is a rare and aggressive skin cancer named after Merkel cells—specialized cells found near the base of the top layer of skin. These cells are linked to nerve endings and help the body sense touch, which is why they’re sometimes called “touch receptor” cells. While MCC was originally thought to develop directly from these cells because of their similar appearance under a microscope, newer research suggests it may come from a different type of cell in the skin.
