There’s a link between obesity and certain cancers, such as breast cancer, colorectal cancer, and cancers of the kidney, pancreas, and thyroid. Scientists aren’t sure if being overweight actually causes cancer. But they do know that fat feeds the growth of existing cancer cells.
Of course, people who aren’t overweight can get cancer, too. So just like anyone else, it’s important for you to keep up with any cancer tests that your doctor recommends.
