Hello doctor. I have a rectal tumor that has just been operated on, the doctor concludes as follows: Carcinoma of the rectum has just invaded the serosa. May I ask what stage rectal cancer has just invaded to the serosa? What is the next course of treatment for my rectal tumor? If the disease recurs, will I have to have surgery again? I thank you very much, Doctor.

Hi doctor! My father went to the doctor and was diagnosed with rectal cancer. I want to ask, can my father have rectal malignancy? Thank you doctor!
