5 things doctors say you should never give your children to help prevent cancer

Doctors often emphasize that some everyday habits can influence a child’s long-term health, including their risk of developing cancer later in life. While no single action can completely prevent cancer, experts agree there are things parents should avoid to help reduce risk.

First, avoid excessive sun exposure without protection. Childhood sunburns significantly raise the risk of skin cancer in adulthood, so using sunscreen, hats, and shade is important. Second, doctors warn against tobacco smoke—both active smoking and secondhand smoke can damage developing lungs and increase cancer risk. Third, limit high-sugar, heavily processed foods; these contribute to obesity, which is linked with several types of cancer.

Fourth, be cautious with unnecessary medical radiation, such as repeated X-rays or CT scans, unless truly needed; overexposure can slightly raise cancer risk over time. Finally, avoid excessive use of tanning beds, which are especially harmful for young skin.

Overall, fostering healthy habits—balanced nutrition, active play, sun safety, and smoke-free environments—can help children grow strong while reducing future cancer risk.
