What symptom is bowel cancer 3 phase?

summary

Like other malignant tumors, colorectal cancer has no special symptoms in the early stage and is not easy to be found. If some obvious symptoms appear in patients with colorectal cancer, it means that colorectal cancer has reached the middle and late stage, and patients with colorectal cancer need active treatment. To prevent the development of colorectal cancer to the late stage, what symptoms of colorectal cancer stage III need to be understood and known?

What symptom is bowel cancer 3 phase?

The main manifestations of right colon cancer are dyspepsia, fatigue, loss of appetite, diarrhea, constipation, or alternating constipation and diarrhea, abdominal distension, abdominal pain, abdominal tenderness, abdominal mass and progressive anemia. The location of the mass varies with the location of the lesion. The mass of cecal carcinoma is located in the right lower abdomen, the mass of ascending colon is located in the right abdomen, the mass of hepatic flexure is located in the right upper abdomen, and the mass of transverse colon is located near the umbilicus. In addition, there may be complications such as fever, emaciation, perforation and localized abscess. At this time, the lesion has entered the most advanced stage.

Because of the narrow sigmoid colon cavity and the sharp angle with rectum, the left colon cancer is prone to stricture and progressive intestinal obstruction, with intractable constipation and increased defecation frequency. Because the obstruction is mostly in the lower part of sigmoid colon, vomiting is light or absent, and abdominal distension, abdominal pain, bowel sounds and bowel type are obvious. When the cancer is broken, blood or mucus can be stained outside the stool. The proximal intestinal obstruction may cause ulcer, perforation, massive blood and abdominal abscess due to persistent expansion, ischemia and hypoxia.

Rectal cancer is mainly manifested as increased frequency of stool, stool thinning, with blood or mucus, accompanied by diarrhea. Because the cancer may invade the sacral plexus, there may be severe pain. If the bladder is involved, symptoms such as frequent micturition, dysuria, urgency and blood flow may appear. The cancer may invade the bladder and form a vesicorectal fistula. Rectal cancer can also cause intestinal obstruction.

matters needing attention

Patients with colorectal cancer must avoid advanced colorectal cancer, otherwise the treatment is more difficult, which is not conducive to the therapeutic effect of colorectal cancer.
