Since January 2024 I have had intermittent pelvic and back pain. I had a fit test in Feb 2024 which returned result of 19. They redid the fit as I suffer from piles in March and June 2024 both came back negative. My bloods are all ok and I have also had a pelvic, abdominal and chest ct scan in October 2024, all clear. I have also had 2 transvaginal ultrasound which were both clear. I have also had 2 abdominal ultrasounds which were fine. Could this still be bowel/colorectal or anus cancer?
