@A MyBCTeam Member ..... I have a chart I made up with all the side effects for the 3 AIs (Aromatase Inhibitors). I took a look and they all have some eye related side effects. Letrozole and Arimadex can cause blurry vision and cataracts. Arimadex can cause yellowing of the skin or whites of eyes. Letrozole can cause eye irritation. Letrozole, Arimadex, and Exemestane can cause vision changes. Exemestane can cause visual disturbances. I would check with your oncologist and eye doctor and see what they have to say. You may want to look up side effects for Tamoxifan. I don't have that drug listed on my chart since it wasn't an option for me, but it's worth a look in case there are less or more tollerable eye related side effects.

I found it from my oncologist that it was feeding the tumor as he put it. So now they want me to take the anti-estrogen therapy, Iโ€™m actually scared to do that because I read that it affects the eyes because my brother had torn retina in both eyes. We have issues in our family so I have to avoid eye side effects..

That's a lot to process, and it makes complete sense to wonder about the connection between Premarin and your diagnosis. You're definitely not alone in asking this question โ€” many MyBCTeam members have shared similar experiences and concerns about hormone therapy and breast cancer.

Premarin is an estrogen-based hormone Show Full Answer

That's a lot to process, and it makes complete sense to wonder about the connection between Premarin and your diagnosis. You're definitely not alone in asking this question โ€” many MyBCTeam members have shared similar experiences and concerns about hormone therapy and breast cancer.

Premarin is an estrogen-based hormone therapy, and estrogen can play a role in the development of certain types of breast cancer, particularly hormone receptor-positive breast cancer. It's a very valid thing to bring up with your oncologist. Here are some helpful things to discuss with your care team:

- Let your oncologist know you were taking Premarin and for how long โ€” this helps them understand your hormone history
- Ask about your breast cancer type โ€” knowing if it's hormone receptor-positive can help guide your treatment plan
- Talk about hormone therapy alternatives โ€” depending on your situation, there may be other options to manage menopause symptoms that are safer for you now

Your medical team is the best resource for personalizing next steps based on your full history. You're asking exactly the right questions. ๐Ÿ’™
