Skin cancer rates are rising due to UV exposure and ozone depletion. Basal cell and squamous cell carcinomas are most common, while melanoma is more aggressive. Early detection dramatically improves survival, and the video explains how advanced disease shows up as fungating wounds and Kaposi's sarcoma.
