Yes. The National Cancer Institute (NCI) website suggests that surgical removal of ovaries reduces the risk of cancer by 50 percent. The process of surgically removing the ovaries or fallopian tube is called Bilateral Prophylactic Salpingo-Oophorectomy or Prophylactic Oophorectomy. Through prophylactic oophorectomy, doctors remove the ovaries in women who have not hit the menopause.
The removal of ovaries reduces the level of oestrogen within the body. As oestrogen is responsible for the growth of certain breast cancers, reducing the level of oestrogen by removing the ovaries slows the multiplication of cancer cells in the breast.
Another study has shown that hysterectomy is another surgical method that slows down breast cancer in women. Hysterectomy is a widely used and a common surgical process of removing the uterus among women aged 40 to 50. Doctors often recommend hysterectomy if the cancer has begun from the uterus and is spreading to the other parts of the body. Like prophylactic oophorectomy, hysterectomy also reduces the level of oestrogen in the body.
Both prophylactic oophorectomy and hysterectomy do not increase the risk of breast cancer. On the contrary, both the surgeries slow the multiplication of cancer cells to increase the survival rate.
