Frankly, I'd think about taking a break until antibiotic clears up the infection.
I stopped chemo when it was causing bleeding thru' skin of legs and arms. Resumed in a few days when home nurse determined I was well enough to go on.
For whatever reason, the oncologists involved in my treatment were not the best resource for me when I had treatment induced side effects. Even now, 2 yrs after treatment, I have a difficult time getting the surgeon who supervises me to offer suggestions on various scarring issues. Like your wife's doctor, he tells me whatever is happening is normal due to radiation scarring.
Main thing...your wife won't be able to comply with treatment is she is ill, so I'd stick with what GP tells you. She can pick up radiation therapy when she stops running a fever.
Thanks, The cancer is breast cancer but involves lymph glands. Yesterday the oncologist said that it was not infected but she was running a low grade fever. She went to a general practitioner who disagreed and said it was infected and prescribed a anti-biotic. Now I'm not sure if this is just an honest mistake or something else. Wondering if she should take a break from treatment until it heals or continue as the oncologist wants.
If oncologist is not concerned, try to relax.
Radiation therapy is extremely harsh on skin. Think a severe burn on area radiated. Like you, I would be concerned with a green discharge.
You don't say what type of cancer your wife has: I'm guessing breast or lymph glands are involved.
I had radiation and chemo for 6 wks when treated for anal cancer. It took about a year for my skin to stop hurting. Your wife will experience phases of discomfort for some time after treatment is stopped. I used a heavy cream and an ointment "Calmaseptine" I believe it was called for ages. It has been two years since treatment, and what I deal with now is radiation scarring. But don't think too far ahead. Radiation oncologist and surgeons are good about telling you what to expect as time passes.
