i was put on Tamoxifen in 2011 after having a lump remove from my breast, classified as a stage 0 non invasive ductile carcinoma. I was to be on it for 5 years but after 4 years i had a stroke. When my breast surgeon found out about that he immediately took me off the Tamoxifen. No reason was found for my stroke, - my cholesterol has always been good, BP good, just slightly over weight, no diabetes, . So could the tamoxifen be the problem and am i pretty much safe from having another one? I otherwise didn't notice any side affects other than maybe some weight gain.
