There are three major types of skin cancers: basal cell carcinoma, squamous cell carcinoma, and the most deadly type, melanoma. Each of these types can look completely different. For example, the thin types of basal cell and squamous cell can mimic a patch of eczema. Whereas deeper basal cells can look like translucent bumps on the skin. Deeper squamous cells can look like hard, red bumps on the skin often with thick scaly skin overlying. And although rarely melanomas can look pink, the vast majority of melanomas are brown to black with irregular colors and borders.
