What is bowel cancer?

Intestinal cancer generally refers to colorectal cancer, which is a neoplasm formed by abnormal gene regulation of normal colorectal tissue under the stimulation of carcinogens, and abnormal proliferation of normal tissue. It is a common malignant tumor in the digestive tract.

The intestines in the human digestive organs are mainly divided into the duodenum, small intestine, colon and rectum. Among them, duodenal and small intestine cancers are rarer, and colorectal cancer is more common in human digestive tract tumors. The pathogenesis of colorectal cancer is still unclear. Studies have shown that the occurrence of colorectal cancer is related to bad eating habits, such as high-fat diets, which stimulate the intestines to produce carcinogens through a series of chemical reactions; high-fiber diets help the delivery and elimination of intestinal contents, reduce the stimulation of intestinal carcinogens on the intestines, and low-fiber diets lead to an increased incidence of colorectal cancer. The progression of colorectal cancer includes local invasive growth, and it can also metastasize to distant tissues and organs along the lymph nodes or blood. Advanced colon cancer may even cause peritoneal implantation and metastasis. The clinical manifestations of colorectal cancer generally include abdominal discomfort, changes in bowel habits, bloody stools, and recent weight loss. The treatment of colorectal cancer mainly includes comprehensive treatment plans such as surgical treatment, radiotherapy, chemotherapy, immunotherapy, and traditional Chinese medicine treatment.

Colorectal cancer refers to a neoplasm formed by abnormal gene regulation and abnormal proliferation of normal colorectal tissue under the stimulation of carcinogens. It can grow by local infiltration and metastasis locally or remotely. Once discovered, it should be treated as soon as possible.
