Dana-Farber Cancer Institute study finds overweight and obese women at greater risk of breast cancer recurrence
Women who are overweight or obese when they are diagnosed with breast cancer are at higher risk of cancer recurrence or related death than are leaner women, according to a new study.
“Several other studies have shown that being overweight or obese at the time that a woman is diagnosed with breast cancer is linked to a higher risk of recurrence. However, questions have been raised in the past whether obese women were receiving relatively lower doses of chemotherapy due to their weight. Our study mandated that each patient received a chemotherapy dose adjusted to her weight, so these results suggest that treatment factors are not responsible for the differences in recurrence rates seen in heavier women,” Dr. Ligibel said.
Although the link between obesity and the development of breast cancer is well known, there has been less research to date looking at its effect on cancer recurrence and survival.
