Drinking, smoking and obesity can increase cancer risk

Almost half of all cancer deaths worldwide are preventable, according to a recent study. That’s because more than four-million deaths related to the disease can be attributed to behavioral risk factors, doctors said.

These include excessive drinking, smoking, and being overweight.

Carrying excess weight can present a slight risk for nearly every type of cancer, doctors said.

When it comes to alcohol, no matter what you drink there’s an increased risk, they said.

Tobacco use is especially harmful, as there are many tumors doctors never see in non-smokers, they said.

It’s important to let your healthcare provider know about any family history of cancer, they said.
