Rajdeep Mysore, MD discusses melanoma, the most dangerous type of skin cancer. Originating from melanocytes, the color-producing cells in the skin, melanomas often appear as black or brown spots. Mysore explains how to identify suspicious moles based on asymmetry, irregular borders, varying colors, or bleeding. Highlighting melanoma’s higher risk in fair-skinned individuals, especially Caucasians, the importance of regular sunscreen use is emphasized. The video also introduces dermatoscopy, a non-invasive diagnostic tool, and advises viewers to consult a dermatologist for any abnormal skin changes to potentially proceed with a biopsy if melanoma is suspected.
