Symptoms of malignant colon cancer

summary

The main types of colon cancer were adenocarcinoma, mucinous adenocarcinoma and undifferentiated carcinoma. The general shape was polypoid and ulcerative. Colon cancer can develop along the intestinal wall, spread up and down along the longitudinal diameter of the intestinal wall or infiltrate into the deep layer of the intestinal wall. In addition to lymphatic, blood flow metastasis and local invasion, it can also spread and metastasize to the abdominal cavity or along the suture and incision surface. In order to prevent this situation, I'd like to introduce the symptoms of patients with advanced colon cancer.

Symptoms of malignant colon cancer

Late manifestations: jaundice, ascites, edema and other signs of liver metastasis, as well as cachexia, rectal fovea mass, supraclavicular lymph node enlargement and other manifestations of distant metastasis.

Left colon cancer: the intestinal cavity of the left colon is relatively narrow, and the feces have been viscous and formed, and this part is mostly infiltrating cancer, and the intestinal cavity is often annular stenosis, so the symptoms of intestinal obstruction appear earlier in clinic, and some even have acute obstruction. The symptoms of poisoning were mild and appeared late.

Right colon cancer: the intestinal cavity of the right colon is wide, the feces are sparse here, the colon is rich in blood supply and lymph, and has strong absorption capacity. The cancer is mostly soft cancer, which is easy to ulcerate and necrosis, causing bleeding and infection, so the clinical manifestations are mainly toxic symptoms. However, intestinal obstruction may also appear when the disease is aggravated.

Patients may have anemia, low fever, fatigue, emaciation, edema and other manifestations, especially anemia, emaciation.
