Basal cell carcinoma is a type of skin cancer that can look like a red or pale lump or a scaly part of the skin. They could look like an ulcer on the skin that doesn’t heal. Basal cell carcinoma grows slowly on the skin and is the least dangerous. People over 50 are more likely to have squamous cell carcinomas. Like basal cell carcinoma, squamous cells also grow slowly and can be red and scaly.
Unlike other types of skin cancer, melanoma can develop on areas of your skin that don’t see the sun. Melanoma might appear as a new spot on your skin, or could develop on an existing spot or mole. It will change shape, color, or size. Nodular melanomas are different from common melanomas, appearing red, pink, brown, or black. These will grow quickly on your skin. Although they’re firm, nodular melanomas might bleed over time.
When looking at your skin, use the ABCDE formula. Any mole that is asymmetrical with an irregular border and different colors could point to melanoma. Show your doctor any moles that are larger than a pencil eraser and evolve over time. Moles that bleed, weep, itch, or tingle should also be looked at by your doctor (per Cancer Council).
