Anastrozol is a medication that plays a critical role in the treatment of certain types of breast cancer. It belongs to a class of drugs known as aromatase inhibitors, which work by reducing estrogen levels in the body. This is particularly important in hormone-sensitive breast cancers, where estrogen can promote the growth of cancer cells. Understanding how Anastrozol works, its effects, and its potential benefits and side effects is essential for those considering this treatment option.
