Lung cancer

By far the most important thing you can do to prevent lung cancer is not to smoke.

You can also probably reduce your lung cancer risk by eating fruit, and this is one of the reasons WCRF UK recommends eating at least five portions a day of a variety of vegetables and fruit.

There is also convincing evidence that high levels of beta-carotene, as might be found in dietary supplements, can increase your lung cancer risk, and this is one of the reasons WCRF UK recommends we do not take supplements for cancer prevention. It is best to get all your nutritional needs through diet alone.

There is also convincing evidence that arsenic in drinking water also increases lung cancer risk, though this is only really relevant in parts of the world without a regulated water supply.
