Out of interest - breastfeeding issues before diagnosis

Back in the distant past, when dinosaurs roamed the earth, I breastfed my son for two years and four months. I had one period, and then fell pregnant with my daughter, who was breastfed for two years and one month. Both preferred the left breast, but perhaps that's because I probably preferred to hold them on that side, which left my dominant right hand free to do whatever at the same time. My cancer, the same as yours, was in the left, preferred breast.
