Scientists discover that exercise will help ward off breast cancer

Swedish scientists have discovered that a woman’s risk of breast cancer is increased if no exercise is done, regardless of whether she is slim or not.

Researchers have issued a warning to slim females not to avoid doing exercise. It is vital that they remain active to ward off cancer. It is not necessary to go to a gym as normal daily activities, such as playing with your children or doing shopping will also help. It is never too late to start an exercise regime.

In excess of 19,000 females around the age of 56 were questioned about their lifestyles and health. The status of their health was then checked on approximately 13 years later. Of these participants, 900 had been diagnosed with breast cancer during the 13-year period. The researchers found that upon analysis of the data, there was an indication that linked the disease to the women’s activity level.

Those who led more sedentary lives were 40% more at risk of developing the cancer than participants who were more active. The exercise link was applicable regardless of the weight of the participants.

According to Yiva Trolle Lagerros, an obesity expert from Stockholm’s Karolinska Institute, it is possible to reduce the risk of breast cancer by doing physical activities, even if your weight is not at a normal level. She added that it was not necessary to do gruelling exercise sessions as everyday activities such as walking to go shopping or to work all offered beneficial effects.

The study did not consider the reason why you would be at risk if you were unfit. It is assumed that factors related to the lowering of immune systems compounds and sex hormones during exercise could have a link to the disease.

This does not mean that weight has no role in breast cancer. According to Professor Trolle Lagerros, overweight females are more at risk of developing cancer, even if they did exercise. Obesity raises the chances of breast cancer by around 58%, whilst being simply overweight increases it by 20%.

The women who are most at risk are those who are obese and inactive. Their level of risk is double that of fit, slim females.
