“Cancer can be prevented”: Doctors with a global reputation found 4 rules that reduce cancer risk by 70 percent

Compliance with only four simple life rules could dramatically reduce the risk of disease of the most common types of cancer, reveals new research published in the scientific journal “JAMA Oncolgy”.

Two scientists from the Faculty of Public Health from Harvard University found only four factors that play a major role in increasing the risk of cancer – smoking, alcohol consumption, body weight and exercise the body.


“Cancer can be prevented. In fact, most cancers can be prevented, and the estimates are 80 to 90 percent of cancer associated with smoking,” said Graham Colditz, professor of epidemiology at Harvard.

“The challenge is now to act within the framework of what we know. There is a very long history of delay from the moment of discovery to convert into practice,” said Colditz.


By examining a number of studies on the influence of lifestyle on the risk of cancer, researchers have established that individuals who meet four criteria have only 60 to 70 percent less chance of developing cancer than those who do not meet one of the criteria.

The first criterion is smoking, which should be stopped entirely. The second criterion is enjoying alcohol, which must be kept to a minimum – no more than one glass per day for women or two for men. Lose weight must be moderate, not too big but not too small – the index weight should be between 18.5 and 27.5. The last criterion is the exercise of the body – people with low risk exercised at moderate intensity for at least 150 minutes per week.
