You won't believe what doctors are saying about the REAL cause to most cancers!

Unhealthy lifestyles are the number one culprit for cancer diagnoses.

For years we've believed the development of cancer is linked to our DNA, but a new study claims that the REAL culprit is an unhealthy lifestyle, which is responsible for 90 percent of all cancer diagnoses.

LOS ANGELES, CA (Catholic Online) - "Healthy habits like not smoking, keeping a healthy weight, eating a healthy diet and cutting back on alcohol are not a guarantee against cancer, they do dramatically reduce the risk of developing the disease," Dr. Emma Smith, of Cancer Research UK, said.

Doctors have been calling for better eating habits, regular exercise and less drugs and alcohol for years, particularly in reference to preventing a number of diseases, so what makes this call different?

One year ago, research claimed most cases of cancer are caused by errors in our DNA that generate at random as bodies age and cells divide. It also claimed two of three cancer diagnoses are the result of both genes and unhealthy lifestyles. However, the new study, which is published in science journal Nature, says this line of thinking is incorrect.

Doctor Yusuf Hannun, one of the authors of the paper titled "Substantial contribution of extrinsic risk factors to cancer development believes "bad luck" genes are not solely responsible, else there would be far fewer cases than there are. 

Hannun believes external contributing factors include poor diets, high alcohol and cigarette consumption, sunburns, certain viruses, pollution and other unidentified factors could be the real defining factors.

Sarah Williams of Cancer Research UK believes the study "fits in really well with what we already know about cancer. While a few cancers are down to kind of just things that happen by chance in our DNA, many cancers are actually down to external factors and that's good news because that actually means we can prevent a lot of cancers."

According to Daily Mail, many critics of the study, which did not include cancers heavily linked to the environment, have been openly speaking against it.

Professor Kevin McConway, from the Open University, said, "The authors' aim is to calculate what percentage of cancers would not arise, if we could wave a magic want and get rid of all possible external risk factors."

Though McConway spoke poorly of the study, he did admit "[t]here would still be cancers, because of the way that cells divide in the body. But there would be fewer of them."

Meanwhile, Dr. Jian-Min Yuan, who works at the University of Pittsburgh, said, "These results demonstrate that a large proportion of cancer is caused by environmental factors and are preventable if their underlying causes are identified."
