10/14/2017Wow. You said that chemotherapy does not cause cancer but that is not the information I received.What I was told by my oncologist (Yale Medical, Residency at University of California, San Francisco) is that it can cause secondary cancer but often years later as reflected in this link from another NCI Comprehensive Cancer Center, UNM: "For patients who received a doxorubicin-based regimen, the rate of second cancers at 10 years was 3.8% and at 15 years it was 7%. The rate of second cancers was 3.4% in patients receiving radiation therapy and 4.7% in patients who did not receive radiation therapy, suggesting that radiation may not increase second cancers in this setting" . If this is incorrect, could you please cite the study that has different stats?

10/15/2017Adriamycin carries a 1-2% risk of leukemia. ALL cancer patients have a risk of getting a secondary cancer whether they took chemo or radiation. Important to remember the purpose of taking chemo or radiation. chemo is to prevent metastatic breast cancer; radiation is to prevent local recurrence within the same breast.
