Hi @Schwen, Firstly, welcome to this site - you'll get lots of info and support here. Treatment isn't a one size fits all and your oncologist will tell you more when you have your first appointment. For me, chemo didn't begin until the surgeon cleared me as recovering from ops which was approximately 1 month from second surgery. I had grade 2 lobular carcinoma, a partial with sentinel node biopsy, then a mastectomy with axillary dissection ( 3 out of 8 nodes positive) - OR/ER+, HER-. I am currently going through chemo 4 X AC 3 weekly, then 12 X paclitaxol weekly, then it will be rads and hormone therapy. Your treatment might be similar or might be different. Talk to your doctor's about your planned holiday. It may be that you can fit it in between.
