Multiple Childbirth Can Increase the Risk of Triple-Negative Breast Cancer

10 to 20 percent breast cancer patients suffer from one of its rare kinds known as the Triple-negative breast cancer. Researchers knew until now that childbirth reduces the risk of cancer development in women and multiple births can reduce the risk further.

But, new studies carried out at the Fred Hutchinson Cancer Research Center have revealed that multiple births in fact increase the risk of developing this rare form of breast cancer. The results of the study are to be published in the March 16 issue of the Journal of the National Cancer Institute.

The exact mechanism behind this new discovery remains unknown. However, the experts suppose that in the case of women suffering from this breast cancer, the hormones of pregnancy might cause abnormal changes in the tissues of their breast.

The researchers also believe that the condition pregnancy might make the breast more susceptible to certain cancer causing substances, although it reduce the over all risk of developing cancer in women.
