Jimmy Buffett had Merkel cell carcinoma, a rare and aggressive form of skin cancer. He battled this cancer for about four years before passing away on September 1, 2023, at the age of 76

. Merkel cell carcinoma (MCC) affects the top layer of the skin (epidermis) and is much rarer and more deadly than other skin cancers like melanoma or basal cell carcinoma. It tends to grow rapidly and has a high risk of spreading (metastasizing) to other parts of the body, which makes treatment challenging

. Buffett's diagnosis brought significant public attention to this uncommon cancer, highlighting the importance of early detection and sun protection to reduce risk. MCC tumors usually appear as painless, firm nodules on sun- exposed areas such as the head, neck, or eyelids. Risk factors include older age, male gender, UV exposure, weakened immune system, and light skin type

. Despite his illness, Buffett continued to perform while undergoing treatment until his health declined shortly before his death

. His experience has helped raise awareness about Merkel cell carcinoma and the need for vigilance regarding skin changes and sun safety
