How to choose a colon cancer screening method?
Colon cancer is a common malignant tumor of the digestive tract that occurs in the colon, and it is more likely to occur at the junction of the rectum and sigmoid colon. The incidence rate is the highest in the 40-50 age group, with a male to female ratio of 2 to 3: 1. The incidence is the third in gastrointestinal tumors.
Colon cancer is mainly adenocarcinoma, mucinous adenocarcinoma and undifferentiated carcinoma. The general shape is polypoid, ulcer type and so on.
Colon cancer can circulate along the intestinal wall, spread
up and down along the longitudinal diameter of the intestinal tube or
infiltrate deep into the intestinal wall.
In addition to lymphatic vessels,
blood flow and local invasion, it can also be implanted into the abdominal
cavity or spread along the suture and incision.
Patients with chronic colitis, colon polyps, and male obesity are susceptible.
