Hello all,
my father (72) has recently been diagnosed with non-small non-squamous cell lung cancer (adenocarcinoma). He is a smoker for 50 years. He stopped smoking almost 3 months ago when he started having a persistent cough leading to his being diagnosed with pneumonia and later with the cancer. He is between stage 3 and 4 as the doctors are not sure if a spot in his left lung is a metastasis or not. His primary tumor is in his right lung, around 4 cm, no metastases in other organs, just in the lymph nodes around the primary tumor (this is what I understand from the doctors explanation). They saw some liquid in his heart so they backed-off their initial decision to start him on combined radio-chemo treatment and he just had his first keytruda infusion.

He has a persistent cough and I was wondering if somebody had this as well. It is not a deep cough, it is like it's coming from his throat rather than his lungs. It's more like a non-productive cough - no blood, just some white foamy saliva after a huge cough episode. I was wondering is this from the cancer, as I read the cough is different, or is it possible it's an effect of his stopping smoking, or should we be seeking for any other reason (I read there is something called psychogenic cough). I would appreciate it if somebody has had any experience with something that can relief the cough even a little bit.

Thank you and I wish good luck to each one of you!
