I have had a small DCIS with 7mm of invasive (grade 3) cancer removed and lymphs tested (clear), right breast Er positive and HER2 neg. Am now on Letrozole for 7.5 years ( I am 52) Due to do a weeks radiotherapy next week and that was supposed to be the end of the current treatment plan. Oncologist called to say the Oncotype test came back with a high reoccurrence score and I now have to do Chemo, starting three weeks post radiotherapy. Wasnt expecting this and a bit shocked so forgot to ask her questions!, but now i have loads of questions and cannot get an appointment with the Oncologist until after radiotherapy all done. For this type of Adjuvant Chemo does anyone know or have experience of how many cycles is usally recommended and over how long?
