[|Human|] Hello Doctor, My husbands colon cancer recurred in the omentum. It was a tumor measuring 2 cm.  He had it removed and the surrounding tissue showed no spreading of cancer.  He had 22 Lymph nodes removed with cancer when they had originally operated.  Now he is considered 4th stage cancer. Are the percentages high for another recurrence? Please explain.  And if you need more info. let me know.  thank you.   Valerie
[|AI|]  Hi, dairy have gone through your question. I can understand your concern. He had colon cancer.  It was removed with lymph node dissection.  However, there may be some cancer tissue remains in surrounding areas or margin.  So it causes recurrence of cancer.  Now it is stage 4 cancer.  So there may be some metastasis also.  Now surgery is not possible.  Only treatment is chemotherapy.  Consult your doctor and plan accordingly. Hope I have answered your question, if you have doubt then I will be happy to answer. Thanks for using Chat Doctor. Wish you a very good health.
