MattyD, that's great news about your mother-in-law's surgery. I was diagnosed with stage 2 CC, 6+ years ago. My tumor was 4.5-to-5cm. I had a liver resection, and 75% of my liver was removed. The margins were negative for any remaining cancer, but very close, just millimeters. They recommended adjuvant therapy. So following my surgery I had 6 weeks chemo and radiation. My chemo was in pill form, Xeloda.
Following my surgery, and chemo and radiation, I was tired and pretty weak. But slowly, each day, I would feel better, and knew I was progressing and getting better. I took it one day at a time.
Although we can not guarantee the cancer can/will come back, there are many success stories on this site. As I mentioned, I am now at 6+ years as a survivor, and basically "cancer free". I wish the best for your mother-in-law in her recovery and journey.
