Hello. I had Triple-negative breast cancer (diagnosed in Aug. 2020) I'm 66 years old and after chemos, lumpectomy, and serial sectioning of sentinel node surgery (only 1 node removed, and it was clear) my tissue was removed with the 2 cm margin (tumor completely disappeared on my third infusion of Taxol) my biopsy came back as a complete pathologic response. Next was the radiation that was highly recommended, especially after a lumpectomy. I only needed 4 weeks, 5 days a week sessions, full breast radiation, and the last 4 sessions were boosters in the area of the tumor site. The oncologist said relapse without it runs 20 to 40% and with radiation used reassurance is 5 to 10%.
