Certain everyday habits like smoking, drinking too much alcohol, being overweight, and not moving around enough can raise your chances of getting different kinds of cancer.

In Switzerland, between 2015 and 2019, the top lifestyle habits linked to cancer cases were smoking, being overweight, and drinking too much alcohol.

In Switzerland, about one out of every four cancer cases that could have been avoided were linked to things people can change, like smoking, drinking too much, being overweight, not exercising enough, and eating poorly.

People with obesity have a higher likelihood of developing several types of cancer, including endometrial, postmenopausal breast, colorectal, liver, and pancreatic cancers, and the risk increases with higher levels of body weight for endometrial and postmenopausal breast cancer.

This claim says that smoking causes more cancer worldwide than any other risk factor we can change, responsible for about 15 out of every 100 cancer cases. Infections come next at 10 cases, and alcohol at 3 cases.

Even small amounts of alcohol are linked to a higher chance of developing breast cancer in women, whether they have gone through menopause or not.
