Being thinner allegedly helps decrease the chances of breast cancer returning, according to a New York study. Obese women treated for breast cancer are more likely to suffer a relapse than thinner cancer survivors, the Daily Mail notes. The recent Albert Einstein College of Medicine’s Montefiore Medical Center study is reportedly the first time breast cancer recovery rates have been linked so tightly to weight and body fat.
Albert Einstein College of Medicine’s Montefiore Medical Center researchers participating in the study concluded that obese women have an increased chance of dying prematurely and feel the statistics are connected to hormonal causes. The breast cancer study also suggests that body fat inflammation and hormonal changes could cause the cancer to recur and spread in some patients despite quality treatment.
Prior breast cancer studies suggest the increased cancer risk in heavy women was likely due to “under-treatment” with chemotherapy drugs. Breast cancer researchers in the earlier study believed that heavy and obese women could be receiving chemotherapy doses designed to aid thin breast cancer patients.
The Albert Einstein College of Medicine’s Montefiore Medical Center study included approximately 7,000 patients. The New York study breast cancer study was conducted under the direction of Dr. Joseph Sparano.
“We found that obesity at diagnosis is associated with about a 30 percent higher risk of recurrence and nearly a 50 percent higher risk of death, despite optimal treatment. Treatment aimed at interfering with hormonal changes and inflammation caused by obesity may help reduce risk of recurrence,” Dr. Joseph Sparano stated, according to the Daily Mail.
The Albert Einstein College of Medicine’s Montefiore Medical Center breast cancer study compared the health outcomes between heavy and obese women with those of thinner women during three National Cancer Institute trials.
