Mom did 7 infusions of carbo/taxol and got her ca125 down to 89. She had the PET/Ct scan that showed no cancer. But her CA went up to 160 and now gyn/onc wants to try Gemzar. Mom got such bad neuropathy in her feet that she can barely walk. Has to use a walker or wheelchair to get around. She's started to do physical therapy and it's helping her to get walking. She still has terrible pain in her feet and they're numb all the time. Told the longer she's off the chemo it will continue to improve. I've read that it can be permanent. But, hope not! Mom doesn't know what to do. Start chemo again or wait for symptoms or something to show up on a scan? Do you treat the number or wait for symptoms or something to show up on the scan?
