Widespread screening for skin cancer may not be necessary, but it is important to understand the risks behind UV overexposure and to get checked early if you have concerns.
Cancer vaccines are an emerging personalised treatment for cancer. Using the same mRNA technology as COVID vaccines, they stimulate the immune system to destroy cancer cells.
People with deeply-pigmented skin can also get skin cancer. But there is no evidence to suggest that this occurs because of sunburn or exposure to the sun.

Newly reported study findings suggest a link between eating more fish and dangerous skin cancers. But the findings are based on observations only and more research is needed.
