There are many women who claim that their breasts grow when taking birth control pills and yes this does hold some truth, contraceptive pills can make your breasts bigger, the key thing is that before considering any kind of contraceptive pill it is very important to speak with your doctor first.
How they work
The female breast actually has estrogen receptors so if the contraceptive you are taking contains estrogen it is most likely that you can expect an increase in breast size, however, this is not the case for all women. Every woman will react differently to higher estrogen levels, in fact, some women may not only notice an increase in breast size other women may gain weight. Unfortunately, most breast pills don’t contain the high amounts of estrogen that they used to so the impact on breast growth may be minimal.
While birth control pills might seem like a logical way to increase breast size, they can have side effects. Some of the side effects can include dizziness, tender breasts, headache, nausea and even excess bleeding but this is in extreme cases. A contraceptive should be taken for only one reason and that is to prevent pregnancy, if in fact your breasts do grow then you, in fact, received a double benefit from the pill. Birth control pills with higher doses of estrogen are more likely to increase breast size, however, you must also be aware that there have been several studies linking prolonged or excessive contraceptive use to certain types of cancer.
