10. Basal Cell Carcinoma
BCCs or Basal cell carcinomas are abnormal lesions, or uncontrolled growths that arise in the skin’s basal cells, which line the deepest layer of the epidermis (the outermost layer of the skin). BCCs often look like open sores, red patches, pink growths, shiny bumps, or scars and are usually caused by a combination of cumulative and intense exposure to the sun, as well as less intense occasional sun exposure.
