How to self-check for colorectal cancer?

Colon cancer is hidden, and early clinical symptoms are not obvious and easy to be ignored. Positive fecal occult blood is common in the early stage. If middle-aged or older people have the following symptoms for unknown reasons, they should be alert to the possibility of colon cancer:

1. Recent changes in bowel habits, such as increased bowel movement frequency, diarrhea, constipation, etc.; or persistent abdominal discomfort, dull pain or bloating, aggravated abdominal pain or paroxysmal colic in the case of intestinal obstruction.

2. Blood or pus in the stool.

3. If you feel a mass in your abdomen, it is usually the tumor itself, and sometimes there may be a blockage of fecal accumulation in the near-intestinal cavity. Most masses are hard and nodular. If it is transverse colon or sigmoid colon cancer, there is a certain degree of activity.

4. Systemic symptoms: Due to chronic blood loss, cancer ulcer infection, toxin absorption, etc., patients may experience progressive anemia, weight loss, fatigue, low fever, etc.

5. In the late stage, symptoms of advanced cancer such as liver enlargement, jaundice, edema, ascites, and clavicular lymph node enlargement may appear.

If one or more of the above symptoms occur, you should be vigilant, do not diagnose the disease, take medicine on your own, and go to a regular hospital for examination to avoid delaying the disease and losing the best treatment time.
