Breastfeeding Study Suggests Possible Improved Prognosis Of Certain Types Of Breast Cancer

Over the past couple of years, the topic of breastfeeding has been highly debated — not just on how beneficial it is for both mothers and their children, but arguments of decency if done in public. The Inquisitr reported about mothers who were punished for breastfeeding in public, such as flights, restaurants, and even during a child support hearing.

Despite the sensitivity of the situation, a woman’s breasts were made to feed their children. As a matter of fact, numerous research studies found benefits for breastfeeding. Now, another benefit was found, as breastfeeding might improve prognosis of certain types of breast cancers for mothers.

The study was done by the Journal of the National Cancer Institute (JNCI). Through a study of questionnaires, medical records, and tumor tissue samples of 1,635 women previously diagnosed with breast cancer, JNCI found a 30 percent decreased risk of breast cancer recurrence for those with previous breastfeeding history. The percentage increased if the patient breastfed for six months or more. Not only that, but breastfeeding was associated with a 28 percent decreased risk in death related to breast cancer.

Huffington Post followed up on the study by the Journal of the National Cancer Institute by stating the research is nothing new. Promising evidence of breastfeeding’s ability to prevent recurrence of certain breast cancers was done in the past. However, this study seems to be the first compelling evidence that breastfeeding can decrease breast cancer recurrence in those who beat breast cancer.

It should also be noted that the Journal of the National Cancer Institute’s findings were significant to luminal A tumors. There were also improved prognoses in luminal B tumors and basal-like tumors, but they weren’t insignificant statistically. Fortunately, luminal A tumors are the most common type of breast cancer, which means if more women breastfed their children, the recurrence of breast cancer may go down overall for those who survive it initially.
