Hi @Pommy8, I had grade 3 no lymph and early breast cancer. My ki67 was really high. I also prior to my breast cancer had 3 malignant melanoma.
I had genetic testing but no brca gene but I did have one family member (maternal cousin) die of breast cancer. They had 3 returns of bc before it got her in the end. I also had another maternal cousin die of ovarian cancer.
So after going through my risk profile and pathology I did have chemo. 3 rounds of AC and 9 of taxol. I also had radium as I had a lumpectomy and now I am taken Letrozole. Tried tamoxifen for 20 months but side effects forced a change.
At the time of changing to Letrozole I reviewed my risk with my oncologist. My grade 3 and other pathology put my return rate as high hence sticking with the aggressive treatment. While chemo was hard and other treatments have their challenges, for me I needed to do whatever I could to stop this coming back. I would be kicking myself if I didn't have a treatment and it came back... but that's me.
I have a friend who was grade 3 and no lymph. She didn't complete her chemo or her radium and she refused tamoxifen. She lasted 10 yrs and then bc came back with another aggressive cancer but in the other breast. She now has removed both her breasts.
It's a big decision. Weight it all up and be confident in you decision. It is your decision to make.
