What is colorectal cancer?

Colorectal cancer is a general term for colon cancer and rectal cancer. Colorectal cancer refers to malignant lesions of the colorectal mucosal epithelium caused by multiple carcinogenic factors such as environmental or genetic factors. It has a poor prognosis and a high mortality rate. Colorectal cancer is a malignant tumor originating from the colorectal mucosal epithelium. It is one of the most common digestive tract malignancies.

Among malignant tumors, colorectal cancer is a disease that is highly prevalent, regional, and hereditary. Because there are no obvious symptoms in the early stages of the disease, patients often ignore the possibility of colorectal cancer. In more cases, colorectal cancer cannot be effectively treated in the early stages. Perhaps for this reason, colorectal cancer has a special title: a silent disease. This is because colorectal cancer will have certain symptoms after onset, but it is often not until the middle and late stages that obvious symptoms appear. Colorectal cancer is called a "silent" disease because many patients have no symptoms in the early stages. In fact, the cure rate after the onset of symptoms is only about 50%, while in the early stages, the chance of cure is 80% or higher. The role of screening is to detect cancers that have no clinical manifestations or diseases that may develop into cancer. The goal is to discover potential diseases and the early stages of the disease.

There are some typical symptoms for colorectal cancer patients, among which the more common symptoms are bleeding during bowel movements (blood in the stool, blood dripping after defecation, or blood on toilet paper); changes in bowel habits, such as new constipation or persistent diarrhea; abdominal pain and unexplained weight loss may be manifestations of cancer progression. High-risk factors include a history of breast, uterine or ovarian cancer, inflammatory bowel disease (ulcerative or clonal colitis), and a family history of colorectal polyps or cancer. For those with alarm symptoms, they should go to the hospital for treatment in time; for high-risk groups, monitoring should be strengthened.

Therefore, people should learn more about colorectal cancer. They should not think that as long as there are no symptoms of the disease, the body is healthy. Diseases like colorectal cancer often have no symptoms when they come, and they will not show up until the disease is more serious, which will cause great harm to the patient. There will definitely be some symptoms when colorectal cancer occurs, so there are many aspects of the disease that we need to understand. If we want ourselves to live better in this society, we must have a deeper understanding of colorectal cancer. Here we remind everyone to choose a regular hospital for treatment.

Since the potential risk of colorectal cancer is relatively large, in order to detect the disease as early as possible, it is necessary to have a careful understanding of the symptoms of the disease, which will play a decisive role in the diagnosis and treatment process. Early intervention treatment can greatly improve the cure rate of the disease, thereby enabling a better life.
