Tamoxifen I want to say no

Thanks @melclarity what you have experienced is what I imagine the cancer will do if it wants to anyhow regardless of taking tamoxifen or not, overall it will only provide about 2 percent increase in five year survival to me this Increases to about 3-4 after 10years and the oncologist had no information  or graphs for after that..I am very uneasy about taking it at all there are so many unknowns and i have a family history of vascular issues, and mental health although they dont currently afflict me i dont want to encourage them and still the cancer can still return..I assume I will still be able to have followup mamagram etc if I refuse the tablets or do u get thrown out in the cold?
