Is abortion linked to breast cancer?

A lot of people wonder whether abortion and breast cancer are somehow linked. Both of these topics are difficult for most people to talk about and they usually bring out strong feelings in people. Abortion is known to be linked to personal and even political viewpoints. On the other hand, breast cancer is a thing that most women fear since it is the most common cancer type that women develop. This is one of the main reasons why so many people have such strong emotions towards them. However, there is still no proof that there even is a connection between these two topics.

How do hormones affect the breasts?

Every type of breast cancer in women is always related to the levels of hormones in the body. The levels of hormones are known to change during the life. However, they go through specific changes when a woman is pregnant. The hormones increase when a woman is pregnant and about to breastfeed. Because of this, changes in the breast tissue occur.
