Thanks. He has a follow up appt. with his Radiologist in 2 weeks and then they are doing another biopsy. It is very small. We were told that the radiation continues to work for several weeks after your last treatment. I hope it is not wishful thinking. My father's oncologist said the lymph node could be surgically removed. This whole experiance has been so overwhelming. If not for this support group I would be lost. If I had it to do over again. I would have hired a nurse advocate. I do not think the medical professionals give you enough info.
