Hi all , just a few questions, dont no if any one had a pleural effusion ? My dad had 7 ltrs took away and was told there was rogue cancer cells in the fluid, hes had numerous ct scans, as was told could be metastic cancer , all ct scans was clear ,ultra sounds clear , bronschope was clear , and now off for pet scan in next few days, we are on week 7 next week , firstly he was told asbestosis, then copd, hes fit and healthy and 69, went back yesterday and docs said still cancer even tho no tumours , they are going to start chemo after pet scan regardless if anything is found, dad asked a few questions one being , he had the fluid removed in 3 stages as a lot was present, and they didn’t want the lung too collapse , he asked if the fluid was found in all samples, or first , second or 3rd, his reply was they wasn’t abliged too tell him ? So he has asked for another sample to be taken , if its metastic its not cureable but hopefully he can have treatment, we seem to have gone on 6 almost 7 weeks worrying and his mental health is terrible, may i also say his bloods are clear as is the organs nothing has detected a tumour x
