[|Human|] Hi, My Brother has advanced stage lung cancer that has moved to his liver. Prior chemo and radiotherapy did nothing to the tumour. He had no side effects from both treatments, other than hair loss & a bit tired.His pain is starting to get a little worse and he is started a new mix of chemo tomorrow for the liver. It will be once a week for 6 weeks. He wants to take a 4 hour flight to see a friend during treatment. Will this be ok? Thanks, Lisa.
[|AI|]  Generally short duration flights are not contraindicated during chemotherapy or radiotherapy. But it all depends upon the general condition of the patient. Whether he is up and about and can take care of his routine activities without any help. Even then, there is the risk of contracting infection from other people in crowded places. So, unless absolutely necessary, it is not advisable to go to crowded places like airports and planes. Besides, you will need a fit to fly certificate from your treating doctor.
