My boyfriend is 50yrs old, was diagnosed with HIV and Hep years ago and has been doing well on his meds....in Feb he had to have his right lung drained and some scar tissue removed. In March it was discovered he had legions in left lung; which were removed and biopsied. The lower 1/3 of the right lung was a mass of legions which are still there....the biopsy was cancerous and we were told he had stage 4 adenocarcinoma...he did a round of 6 treatments of chemo every 3 weeks with good results and has since had 2 maintenance treatments of the alimta (the most recent one was this past Tuesday) He has started wheezing and is coughing up blood. It was dark when he got up this morning and very pail this afternoon...should we be concerned about this?
