Hi there,
My Dad has undergone Chemotherapy for Lung cancer. There were two cancers overall (one on each lung). One of the lungs was affected around 1/3rd and the second cancer was a very small growth.
He went through all of the tests and confirmed that the cancer hadn't spread at all to the lymph nodes and went ahead with the Chemo treatment. The treatment has finished it's cycle and the Dr was happy to report that both cancers had shrank by more than half and therefore they would proceed onto radiotherapy in order 'tackle them both while they're on the run'.
On the lead up to Radiotherapy, he had an xray in order to prep for the treatment, however he was randomly asked to come into the hospital a week before the radiotherapy was due to begin. Apparently, the xray has found a very small amount of fluid on both lungs and there was something else present. Due to this, the radiotreatment has been cancelled as the potential risk wasn't deemed worth it. Now he has to wait 2-3 months as the current amount is too small to extract a sample from. In the meantime due to also suffering from COPD, he is making appointments with his Dr's to have a new assessment on this as well.
I just wish to ask; is it common for Chemotherapy to cause fluid on the lungs? Is this not a good sign at all? His lymph nodes were clear before the treatment had started, and throughout the entire treatment no fluid was detected until the treatment had finished. Is this a sign that it's spread even more, or just an uncommon side effect?
