No: Sun blocks are actually somewhat effective in preventing some skin cancers that are related to excessive sun exposure such as melanoma. We are now finding, however, that some who avoid any sun exposure develop vitamin d deficiency. The key is moderation.

Nope: However, sun block is very helpful in reducing the effect of uv radiation on developing lethal skin cancers such as melanoma. Avoid excess sun exposure and avoid sunburns, but when out and about always take the added measure of using and re-applying sunblock to avoid toxic damage from the sun.
