Hello @kathyoung I am really glad they weren’t cancerous, but a few cells still have to dealt with I guess.
The lack of side effects might surprise you. For me every side effect was a direct result of the hormone loss. Essentially early menopause. Hot flashes, joint stiffness, a few early old age things. Your journey is, your journey and it will be your own. Tens of thousands of women take these drugs and the small percentage who have serious side effects are the ones who are the loudest on these pages.
I find that walking at least 30 minutes per day helps the stiffness, and I have little rechargeable fans hidden everywhere. I can pull one out during a hot flash, and they stop it in its tracks.
Make sure your doctor is aware of any issues you are having, and of course you can get support here.
Did you have a tumor removed, and was is large enough to anticipate other types of treatments? Do you know what type of BC you have?

I tried Tamoxifen had major s.effects, then Letrozole Non branded bad again then tried Anasrozole which was better, finally retried Letrozole this time the original Brand Femora & it's a game changer. Still some a.effects but minor compared to before.
The problem with all of them is it takes a good 3 mths with one to see if any of the horrid & I do mean horrid s.effects will settle or go. You really have to stick with it & eventually find the best for you.
I've a huge list of health probs on top of cancer which mainly are pain related so it was hard going. Plus I had been on high dose of HRT so comming off that meant an overload of menapause issues & then the Estrogen inhibitors caused another 8ncrese plus the pain increase.
So keep trying till you get on with it. I'm now OK with Letrozole but how long I'll stay with it I'm not sure if my bone scan shows any osteopena ill def come off it & try Tamoxifen again or stop for a while...good luck.
At least Radiation is short & quick x
