Skin Cancer in Transplant Recipients: Increased Vulnerability - FAQs

Q1. How much more likely am I to get skin cancer after a transplant?

Transplant recipients are up to 65 times more likely to develop squamous cell carcinoma, the most common type of skin cancer, compared to the general population. The risk for other types of skin cancer is also increased.

Q2. Why do immunosuppressant medications increase skin cancer risk?

These medications suppress your immune system to prevent organ rejection, but they also make it harder for your body to fight off abnormal skin cells that can turn cancerous.

Q3. What are the most common types of skin cancer in transplant recipients?

  • Squamous Cell Carcinoma (SCC)

  • Melanoma

  • Less common: Merkel cell carcinoma and Kaposi sarcoma

Q4. How can I spot skin cancer?

Regularly examine your entire body for new or unusual moles, scaly patches, or sores that don't heal. Be aware of any changes in existing moles.

Q5. How often should I see a dermatologist?

Schedule a full-body skin exam with a dermatologist at least once a year, or more often if recommended by your doctor.

Q6. How can I protect myself from skin cancer?

  • Practice sun safety: Seek shade, wear protective clothing, and apply broad-spectrum sunscreen with SPF 30 or higher daily.

  • Be aware of medication side effects: Some immunosuppressant medications can increase sun sensitivity. Talk to your doctor if concerned.

  • Perform regular self-skin exams: Once a month, check your entire body for suspicious changes.
