Food-borne illnesses are common, sickening 48 million Americans each year, hospitalizing 128,000, and killing 3,000. One way to keep food safe is to clean the refrigerator and pantry regularly to cleanse surfaces and purge dated and possibly contaminated products. The process should include taking all items out of food storage areas, washing all surfaces, checking expiration dates, assessing products' smell and appearance, marking dates packages are opened, and avoiding cross-contamination between raw and ready-made foods.

People can also reduce their overall cancer risks by stopping smoking, avoiding alcohol, exercising, and maintaining a healthy weight.

A 2023 study of lab animals suggests that the population of microbes in an individual's gut may influence the risk of developing Alzheimer's disease. Researchers found that healthy lab rats developed signs characteristic of Alzheimer's disease when they were injected with gut microbe samples from people with Alzheimer's. Rats that received samples from the most severely affected Alzheimer's patients developed the greatest brain abnormalities and memory problems. Rats did not develop these problems when they were injected with samples from people who had no signs of the disease.
