As a rule, it is best to avoid the sun when your shadow is shorter than you are. Protective clothing, such as a hat and long sleeves, can help block the sun's harmful rays. You can also use sunscreens to help protect yourself. Those rated 15 to 30 block most of the sun's harmful rays. Drinking large amounts of alcohol increases the risk of cancer of the mouth, throat, esophagus, and larynx.
Alcohol can damage the liver and increase the risk of liver cancer.
Some studies suggest that drinking alcohol also increases the risk of breast cancer. So if you drink at all, do so in moderation - not more than one or two drinks a day. Exposure to large doses of radiation from medical x-rays can increase the risk of cancer. X-rays used for diagnosis expose you to very little radiation and the benefits nearly always outweigh the risks. However, repeated exposure can be harmful, so it is a good idea to talk with your doctor or dentist about the need for each x-ray and ask about the use of shields to protect other parts of your body.
