I have gone through treatment for grade 1malignant tumor of the breast no lymph nodes 1cm clearance radiotherapy complete my specialist is recommending tamoxifen but said probably wouldn't be alarmed if i decided not to take it. I am trying to make the best decision here but finding it too difficult. I am not happy about some of the side effects ... clots cancer of the uterus fluid retention weight gain and visual problems as i have a small concern already with my left eye.I just wonder if it is worth the worry of side effects for a low grade tumor that has been treated successfuly. please advise thank you!!
