A study by The World Cancer Research Fund is suggesting that cutting bacon and alcohol from your diet could reduce your risk of getting cancer by as much as 40 percent, WSET reports.

The study analyzed data from 51 million people and found that people who ate even the smallest amounts of processed meats and alcohol increased their risk of getting several types of cancer according to WRIC.

The study also found that obesity could soon be the "number one risk factor for cancer", overtaking smoking.

There is evidence that shows obesity is the root cause of at least 12 different types of cancer.

Obesity is linked to liver, ovary, prostate, stomach, mouth and throat, join bowel, breast, gallbladder, kidney, esophagus, pancreas and womb cancers.

The study is going to be presented in Vienna, Austria, to the European Congress on Obesity to urge people to "drink mostly water and unsweetened drinks" and limit the consumption of processed foods.
