I had surgery on May 10, 2025, for a benign Myxopapillary Ependymoma, with near-total removal of the tumor. After that, I received 45 Gy IGRT radiation, completed on July 11, 2025. Since the surgery, I’ve had constant constipation, which only gets better with laxatives but then causes loose stools. There’s no blood, but sometimes a small bit of white mucus appears before stool. My CEA test from Healthian Lab showed 2.57 (normal 0–2.50), and a month later, Dr. Lal Path Lab showed 3.78 (normal 0–3.80). I’m a non-smoker, but these slight changes in CEA have made me anxious .
