Hi, in April 2024 I had a right breast mastectomy for stage 0 DCIS. I have issues with AFib & diabetes, so decided to just remove it & I wouldn't need chemo or radiation treatments. They actually found a stage 1 inside the breast tissue that was removed & said good thing I opted for the mastectomy, which was my choice& went flat. Im 70 yrs. & rather be safe. Now I'm having to take Anastrozole for 5yrs. I started a few weeks ago & am having lower back pain, sciatic with my leg actually giving out pain & am thinking of stopping the medication. I'm reading to many side effects!! I also had a full right knee replacement surgery 2 months ago, just after the mastectomy. What should I do about this Anastrozole for cancer? I'm tired & scared of all the side effects that's a possibility of getting.
