Do sunblocks stop skin cancer?
Most sunblocks block UVB and reduce your chances of getting squamous or basal cell carcinomas. There is conflicting information about the most deadly form of skin cancer – malignant melanoma. People who use sunblock do still get this disease – but this may be because they spend far more time in the sun. To prevent skin cancer, the best advice is to avoid the sun between 11 a.m. and 3 p.m., wear a hat, long-sleeved shirt and sunblock.
