Detailed explanation-1: -Sometimes an injury can cause a lump that’s not cancer. This can be bruising or scar tissue that can form when the body naturally repairs itself. There’s no evidence to suggest that these lumps increase the risk of cancer, but they may need treatment if they don’t go away on their own.

Detailed explanation-2: -Can injuries cause cancer? Falls, bruises, broken bones, or other such injuries do not cause cancer. Sometimes a person might visit a health care provider for an injury and cancer is found. But the injury did not cause the cancer; the cancer was already there.

Detailed explanation-3: -Smoking, a high-fat diet, and working with toxic chemicals are examples of lifestyle choices that may be risk factors for some adult cancers. Most children with cancer, however, are too young to have been exposed to these lifestyle factors for any extended time.

Detailed explanation-4: -Leading risk factors for preventable cancers are smoking, getting too much ultraviolet (UV) radiation from the sun or tanning beds, being overweight or having obesity, and drinking too much alcohol.
