Current research has revealed that regular visits to the gym along with conventional treatment are an important addendum to treating breast cancer. Latest studies have revealed that pre- or peri-menopausal women with hormone-sensitive breast cancer may have poorer prognosis if they are obese.
The latest study was carried out by Oxford University and was presented in the 50th annual meeting of the American Society of Clinical Oncology, this week.
Dr. Clifford Hudis, an oncologist at Memorial Sloan Kettering Cancer Center told CBS News, “That’s the novel finding here. We used to think that this association was really seen primarily in older women, here it’s being seen in young women.”
An analysis of data from 70 trials conducted on 80,000 subjects who were already diagnosed with breast cancer led to the above conclusion. However the researchers did not find any co-relation between obesity and breast cancer outcome in the elderly and post menopausal women. The link between obesity and breast cancer in pre menopausal women has been hinted though researchers are still trying to pinpoint the relation between the two.
One common hypothesis is that fat cells encourage the production of estrogen in the body and this increases the risk of developing estrogen receptor positive breast cancer. Such form of breast cancer grows after receiving signals from the female hormone and is also one of the most frequently diagnosed. Scientists also opine that increased obesity increases inflammation in the body which also elevates the ability of cancer cells to grow and thrive. It is still not clear if weight loss after diagnosis will improve the health but research have indicated that reducing obesity does have a role to play in breast cancer risk and survival.
