What are Aromatase Inhibitors?

Aromatase inhibitors are mainly used to treat hormone receptor-positive breast cancer. They work by blocking the enzyme aromatase, which turns the hormone androgen into estrogen in the body. Aromatase inhibitors do not work on hormone receptor-negative breast cancer.

More About Dr. Ley

Because aromatase inhibitors cannot stop the ovaries from producing estrogen, these medications are mainly used to treat women who are post-menopausal.

There are 3 different types of aromatase inhibitors used to treat breast cancer, including anastrozole, exemestane, and letrozole.

“The level of care is excellent.”

I have no words to express my gratitude for Dr. Ley! I was diagnosed Feb. 2020 and Dr. Ley besides being the best in her field and doing an amazing job on my double mastectomy she was even able to save my nipples. She is also a remarkable human being, patient, kind very clear in explaining everything and making you feel heard and safe in her hands. I 100% recommend her and her very helpful, kind and amazing team! If you have recently been diagnosed this is the team you want to have your back!

Dr. Ley helped me through the first round of BC in 2017 with kindness, compassion and expertise! I had absolutely no reservations when trusting her for a 2021 and now for the 3rd time I can’t imagine going through this without her. She is a lion when it comes to fighting for you, calls you personally even though she has to be the busiest Dr. and mother I know. She’s considerate of your needs, fears and concerns and never lets you go it alone. Can’t say enough good!
