Chemotherapy for stage 4 lung cancer and productive cough. Following the failure of my immunotherapy treatment after less than 6 months I have been started on Carbo/Pemetrexed chemotherapy. Following my first treatment I seem to have developed the production of phlegm. it is very limited but if I don't try to get rid of it my breathing is even more noisy, particularly when i lie down. I would love to think this is because the cancer is being attacked but I am worried that it is a further development of cancer spread.
Has anyone else experienced this type of side effect? I will have my blood checked in 9 days and this will be followed up with a phone call from the doctor so I hope to ask them at this time but it would be nice to hear your experiences. Thank you
