KEY POINTS

  • 1.7 million individuals diagnosed with invasive cancer
  • 600,000 cancer-related deaths every year in the U.S.
  • 2.5 hours of physical activity per week prevents cancer

With about 1.7 million individuals diagnosed with invasive cancer and over 600,000 cancer-related deaths every year in the U.S., the importance of cancer prevention needs to be highlighted. A new study suggests that doing this for about twenty-five minutes daily can prevent seven different kinds of cancer.

Needless to say, regular physical activity offers great health benefits. But a recent study published in the Journal of Oncology has reported that regular exercise might ward off seven different types of cancer. The researchers who collected data from 9 different cohort studies which involved 755,459 people in the age group 32-91 years reported some very interesting trends in the exercise rates and cancer incidence.

The findings of the study revealed that people who get a minimum amount of exercise see lower rates of seven different cancer types compared to others who lived sedentary lives.

According to the study, a minimum of 25 minutes of regular physical activity per day prevented the risks of cancer of the colon, breast, kidney, liver, myeloma, endometrium and Non-Hodgkin's lymphoma. The researchers didn’t note a universally low level of cancer rates since 8 other cancer types didn’t see any significant decline in those who exercised regularly.

It is previously known that regular exercise is linked to a reduced risk of colon and breast cancer. But the 2018 US Physical Activity Guidelines Advisory Committee has found strong evidence that regular physical activity is linked to a reduced risk of several additional cancers including endometrial, bladder, esophageal adenocarcinoma, kidney, and gastric cancer. Furthermore, the analysis of 1.44 million adults suggested that leisure-time physical activity is linked to a reduced risk for about 13 different types of cancer.

The findings suggested that regular physical activity was associated with up to 10% reduced risk of breast cancer and about a 27% reduced risk of liver cancer. Also, the researchers highlighted that depending on the cancer type, the individuals noticed a lower risk with the recommended amount of regular physical activity and certain other noticed significantly higher benefits.

U.S. Health experts recommend roughly 2.5 hours of moderate-intensity exercise per week. The study doesn’t conclude that exercise isn’t what causes a reduced rate of certain cancer types but that it is possible that exercise-related health improvements could have been contributed to the cancer-mitigating effects.

“Health care providers, fitness professionals, and public health practitioners should encourage adults to adopt and maintain physical activity at recommended levels to lower risks of multiple cancers” concluded the study authors.
