Regular exercise is essential for good health, prevent and defend the body from various diseases ranging from osteoporosis to heart disease. However, when the breast cancer (breast cancer), health experts do not agree on whether the sport really able to reduce or lower the risk of developing breast cancer. Study or research on this topic agree and disagree, but the latest research to help give you an idea why. Taking into account all kinds and types of breast cancer as a single disease, and by integrating physical activity at all points during a woman’s life, the researchers experienced loss of an important relationship between the two factors.

What, when and why?

Health experts know that not all breast cancers are the same. For example, some breast cancer will grow faster in response to the hormones that occur naturally in the tubh, such as estrogen and progesterone, and is referred to as breast cancer estrogen receptor positive (ER +) and / or breast cancer progesterone receptors positive (PR +).

Breast cancer that does not respond to these hormones are called estrogen receptor negative cancers (ER-) and / or progesterone receptor negative (PR-). These differences are important because of the difference it helps researchers understand why in a woman developing breast cancer, a difference that also help doctors provide the best treatment for each type of breast cancer.

German researchers have investigated a number of 3414 women who had menopause (post-menopausal) breast cancer as cases and 6569 the number of women without breast cancer as controls to determine how physical activity at different times in a woman affects their risk of types of breast cancer. They were asked about recreational physical activity and non-recreational (including work and household activities) between the ages of 39 and 49 and after age 50 years.

The researchers found that, in women who are registered with the level of physical activity recreation highest (sport) after the age of 50 years concluded to reduce the risk of developing breast cancer post-menopausal approximately 29% cancer, ER + / PR +, where this type of cancer is the cancer most frequent and developed than the women with the least amount of physical activity after age 50 years. Whatever type of physical activity, recreational or otherwise, between the ages of 30 and 49 years of no visible effect on the risk of postmenopausal breast cancer. For this type of breast cancer than ER + / PR +, regular physical activity did not decrease the risk of both.

The results also produced, about 75% of all ER + breast cancer, and 2/3 of them are also PR +. This means that regular physical activity after age 50, even if a woman has not had much exercise once, almost can reduce or lower their risk of developing this type of cancer is most common for one to 3 or 1:3 or 1 / 3
