@friend777 cancer CRC diagnosis late summer 2024…immunotherapy and surgery both worked….have been cancer free for about 18 months now….all along, there is surveillance every 3 months, including chest CTs…they always describe my nodules, but then note that there are no changes from the beginning diagnostic CTs…between the CTs and blood tests, especially Signatera, they get a good picture of my health—so far, so good…with cancer, it’s never ‘’over’’, as it can recur, therefore regular testing, especially if the places CRC tends to go. Fortunately I am back to my life, arranging music, etc.—except for back issues, currently under the care of osteopathy. My prayers are with you…if you wish, keep posting your questions and this community will do our best to support and help. Good luck !
