I had a right hemicolectomy in 2021 and luckily it was all removed. My colonoscopy in May was clear and so was my CEA test. I have now developed symptoms of anaemia and had a blood test on Thursday. Awaiting results. I am worried that this is a sign that cancer has returned. Has anyone experienced Anaemia 17 months after cancer which hasn't been a recurrence? Are there other reasons? I'm so worried
