My 34 year old son has recently been diagnosed with colon cancer which has spread to liver. He had a colonoscopy which was extremely painful for him as they could not offer sedation as they said his blood pressure was too low. They took 14 biopsy samples but have now said the lab have found them insufficient to determine all the results they need to decide the content of his chemotherapy. They want to gather more biopsies via flexible sigmoidoscopy. My son is terrified of being refused any sedation again - and no one seems to be able to offer any reassurances. Is it a common occurrence to have to repeat biopsy sampling due to insufficiency of the first sample ? Any ideas about trying to overcome my son’s anxiety and fears about this further test as no one seems able to give any assurances in advance about sedation/ pain relief.
Thanks
