Your doctor may have prescribed you a drug called Tamoxifen as a treatment for breast cancer. It's normal to have some questions, curiosity, and perhaps even anxiety about such an important drug. So, today we'll talk about this drug, how it affects our bodies, what we need to be careful about, and the possible side effects.
What is Tamoxifen? How does it work?
Simply put, Tamoxifen is a drug that controls the growth and spread of breast cancer cells, and also prevents the cancer from recurring.
Think about it, some types of breast cancer are like a little plant. This plant needs water to grow and get bigger. In the same way, these cancer cells need the female hormone called estrogen to grow. The drug tamoxifen does a very subtle job. It goes into the breast tissue and blocks the estrogen hormone from reaching those cancer cells. It's like closing the water pipe to the plant. Then, without estrogen, the cancer cells lose their ability to grow and spread.

The more complete your doctor has about you, the safer your treatment will be. So, before starting tamoxifen, be sure to tell your doctor if you have any of the following conditions:
