Thank you @vivi1 for bring this to our conversation, and @colleenyoung for providing the link. This is the best way I can explain what I know with what I think I just read. Like all of our cancer treatments there are risks to tamoxifen. The risk being discussed is primarily but not exclusively endometrial changes. Tamoxifen is given because it can dramatically reduce the risk of your breast cancer returning. It might be given for metastatic breast cancer as well. Along with the common side effects of hair loss and hot flashes it carries a risk of endometrial and cervical cancer. I did take it for years, as is it often the choice for young women with breast cancer. It is a cost vs. benefit decision for every person. Let’s talk about what all of you place into that decision making equation.
