Hi Lilly, I too was diagnosed with a adeniod cystic carcinoma, but mine is in the tongue base. I also received radio therapy for this, but was told this type of tumor did not react to chemo. Was the chemo for this tumor or the one in the breast?
I was also told by the doctors that this type of cancer is rare, but they also said it has nothing to do with smoking!!! (I was a very light smoker) I wonder if the difference is in the location?
I understand your problems with radio therapy, my worst is that 8 months later I am still not able to eat or drink anything, but I am hopeful that will get better.
I hope all goes well for you.
