I have finished my 3 cycles of R-CHOP chemotherapy for non-hodgkin lymphoma, the region of cancerous activity was aggressive in the knee and minor in the groin. The oncologist told me the cancer had gone from the body but there was a small cell in the groin that looked abnormal, it wasnt cancer but had potential to turn malignant. She advised I have 3 more chemotherapy cycles for a cell that may or may not turn malignant, she gave no indication whether this would happen.

What I dont understand is how 3 cycles can completely destroy an aggressive form of lymphoma in the knee but has not done anything to a "pre-cancerous abnormality" in the groin, clearly it is not attracted by the chemotherapy and how can I tell if having 3 more cycles would work, she gave me no guarantee this would completely get rid of everything. 

I was reluctant to have chemotherapy in the first place seeing of the damaging effects of the body and the risk of a secondary cancer particularly with the drugs im having gets higher with each cycle.

I asked her if she felt this way why didnt she give me 6 to start with and got some David Cameron waffling response, note, I do respect doctors and in no way undermining their profession and ability. But this is 2 mistakes she has made.

No matter what I am at risk, check my groin often to see if its turned malignant, or have more chemotherapy with no guarantee it will get this abnormality in the groin and the long term effects on my body (secondary cancer aswell)
