A new research study claims that adapting to a healthy lifestyle by refraining from alcohol, smoking and maintaining healthy weight can lower the risks of cancer. The study has found that at least 20-40 per cent of cancer cases could be prevented from making simple changes to your lifestyle.
Mingyang Song and Edward Giovannucci from Harvard TH Chan School of Public Health, Boston in the latest research published online in the journal JAMA Oncology stated that a large proportion of cancer cases and deaths can be halted if people quit smoking, limited their alcohol and maintained healthy Body Mass Index (BMI), possibly between 18.5 and 27.5.
The study also suggested the individuals to follow moderate weekly exercise for at least 150 minutes or intense exercise of 75 minutes.
The study team has analysed data from two groups initially observing their lifestyle pattern and their risk of cancer incidence and death. Around 89,571 women and 46,399 men have participated in the study conducted by the Harvard TH Chan School of Public Health.
As per the team, healthy life style pattern means Never or Past Smoking, No or Moderate Alcohol (2 or less drinks for men a day; 1 or less drink for women a day), weekly physical exercise of 150 minutes and intense physical activity of 75 minutes).
People who met the criteria of all the four of the aspects were regarded having lower risk of cancer and others were considered at higher risk. The researchers found that around 11,731 men and 16,531 women followed healthy lifestyle pattern, regarded as lower risk of cancer, while the others 34,608 men and 73,040 women were at higher risk of cancer.
The researchers also found that 20-40 per cent of these cancer cases and around half of cancer deaths can be able to prevent cancer by making few simple adaptations to their lifestyle pattern.
“These findings reinforce the predominant importance of lifestyle factors in determining cancer risk. Therefore, primary prevention should remain a priority for cancer control”, the team said.
