Findings in a recent study have warned that there are high chances of common type of breast cancer, hormone receptor-positive breast cancer, being diagnosed in obese and over-weight women again, even after being provided with the best treatment.
The study suggests that extra fat stored in the body stimulates the hormones to change and also cause inflammation, due to which some of the breast cancer cases recur and worse spread, even after the treatment.
Moreover, those of the women, when diagnosed of breast cancer are obese; they are more likely to die early, in comparison to those weighing normal.
Joseph Sparano, MD, of the Albert Einstein College of Medicine's Montefiore Medical Center, NY and his colleagues compared the health consequences of breast cancer patients, ranging from stage one to three. These patients, who were a part of the three different National Cancer Institute funded clinical trials, included women who were obese, over-weight and normal.
The trials (E1199, E5188, and E3189), excluded the patients, who suffered other health concerns. Hence, the researchers were able to focus on only the obesity related problems.
The researchers asserted that increasing body mass index was directly proportional to the 30% higher risk of recurrence of cancer and 50% death, despite chemotherapy and hormonal therapy.
