"resistant to chemo" (tumor grew during TC)
My oncologist believes that my cancer is not responsive to chemo (based on the fact that I had lots of residual cancer left in breast and nodes after 6 rounds of TC. In fact, it appears my largest tumor grew a full centimeter on chemo, from 3 to 4cm). I am confused because as grade 3, we all thought chemo would be very effective.
I am concerned now because if I progress (likely in my case of 3c), I will only have hormone therapy options, not chemo, as a weapon to fight with. That won't buy me very many years, let's face it.
Does anyone have insight into why a rapidly dividing cancer would not shrink using a well proven chemotherapy regimen? I didn't expect a complete response since I am hormone positive. but I also didn't expect to hear "chemo resistant" from my surgeon and rad onc. Have others been told anything similar with a more complete explanation of the whys and hows?
It bothers me because chemo was so awful for me - I felt like I died 6 times - and now it appears I did it for nothing.
I wonder if it has something to do with my cancer cells ability to "repair" damage?
