As you know my father has cancer in both lungs and has had 2 chemo treatments so far with Carboplatin Taxol. The nurse was here this morning and she can hear a crackling in the lungs...My question is I know alot of you are doing quite well on this chemo and I was wondering if any of you had this crackling as well? Also, besides the carboplatin taxol is there anything else I might ask them to add to the chemo that alot of you have had results with such as tarceva?? Like I said he has had 2 chemo so far and they are going to do another one next tuesday. The oncologist wants to do 6 I believe in total. My dad is also on 24/7 oxygen and when he sits he is now breathing at 97/98 and before he was at 91..Could the chemo be working? when he is breathing at 97/98 the oxygen is set at 6.5..He wants off the oxygen so bad but we tell him it's going to take time may 4 or 5 treatments? Any input on oxygen would be appreciated.
