There are different types of skin cancer lesions including basal cell carcinoma (BCC), squamous cell carcinoma (SCC) and melanoma.
The primary cause of skin cancer is sun exposure however other factors such as genetics can also be involved.
A good sunscreen (SPF 30+ or higher) is an excellent start to prevent skin cancers.
If you are unsure about any skin lesions, a medical diagnosis by a qualified doctor should be sought.
