I recently took mother-in-law to an appt. They advised she needs an ebus but is too ill and even if do confirm cancer oncologist unlikely to treat due to current health. She had 1.5ltrs fluid drained 4 weeks ago and another 2 last week. Tested and came back clear but mass on lung. I dont think she understood what they were saying and keeps saying i best not lose my hair. Her husband beat lung cancer 8 years ago. She is on oxygen overnight. I'm hoping that i misunderstood what they said but feel this will be a terminal diagnosis if she gets to that stage. Praying i interpreted it wrong but doubtful.
