Basal cell carcinomas (also called ‘BCC’)commonly start as a small red bump on the skin, and can be mistaken as a simple spot or pimple. They grow over time though, and can form a large, dome-shaped growth with small blood vessels visible on their surface. Over time, they can break down and form an ulcer. Some basal cell carcinomas don’t look like this though, and instead can be just a crusted area that occasionally bleeds (eg when drying yourself with a towel), or even look like an area of scarring on the skin
