Knowledge is power Seda and you must gather all the information you need to make this decision.If your head is all over the place get someone to write all your questions down and ask them to go with you to your next appointment and make sure they all get answered.Most decisions about treatment are taken by a Multi Disciplinary team or MDT and the team is made up of a group of specialist doctors,nutritionist,radiologist cancer nurse specialist,and social worker.They review all your test results ,scans and x-rays and then come to a mutual agreement of the best course of action to gain the best result.Percentages are just numbers and mean nothing really, they are just a sort of guidline so don't get hung up on them.Your staging numbers look good but you really cant get complacent with this disease so i wouldn;t hold back on the treatment.
