Sun screen helps you to avoid superficial sun burn, but it doesn't do anything against UVA and the subsequent skin cancer. The only thing which helps against skin cancer is clothing.

That is not correct. Quality sunscreen protects against UVA and UVB.

There is another factor here making the issue even more complicated. It seems there are two basic types of sun screen, chemical and mineral. There is considerable debate as to if some of the ingredients in the chemical types may cause other health issues. There is a lot of info on line about this. I started using a mineral type this season, which can be hard to find. It is white and stays that way making you look like a ghost.
