My boyfriend has been diagnoses with stage 4 non small cell lung cancer squeamish cell second round of kemo not succesful so he just finished more radiation. Has matastisised to brain which is in remission. 1st question last chemo was like six weeks ago he has constipation still hasn't had a bowel movement in six days now and dr keeps giving him meds but all they seem to do is give him pain and bloating. He also is not scheduled for a ct until feb 17 and follow up with oncologist a week later to set up next round of chemo he has just recently had a new onset of coughing up blood. Should I call his oncologist or may bee even get a second opinion?
