What are the symptoms of advanced colon cancer

summary

Recently, my second uncle often feels pain in his lower abdomen and hematuria when he urinates. He feels that everything is abnormal. He went to the hospital and was found to have advanced colon cancer. Now let me talk about the symptoms of advanced colon cancer.

What are the symptoms of advanced colon cancer

First: colon cancer infection can cause chills, fever; perforation can cause diffuse or localized peritonitis; invasion of the urinary system can cause urinary symptoms. The late symptoms of colon cancer can be hepatomegaly, jaundice, ascites, left supraclavicular lymphadenopathy and other organ metastasis.

Second, the middle and late symptoms. When colon cancer develops to the middle and late stage, it often has more serious symptoms. The middle stage of colon cancer is between early stage and late stage, showing progressive development. In the late stage of colon cancer, the right side of the abdomen can touch the mass, and has a nodular feeling, which is not easy to push. When the mass is combined with infection, it has tenderness. At this time, patients will appear progressive anemia, low fever, progressive emaciation, vomiting, liver swelling, jaundice and ascites and other symptoms.

Third: the change of defecation habit and fecal character. It is the result of cancer necrosis, ulceration and secondary infection. Because the toxin stimulates the colon to produce the change of defecation habit, the frequency of defecation increases or decreases, sometimes diarrhea and constipation appear alternately, abdominal colic can appear before defecation, and relieve after defecation. If the location of the cancer is low or located in the rectum, there may be rectal irritation symptoms such as anal pain, poor defecation or irritability. Feces often do not form, mixed with mucus, pus, sometimes large blood content, often misdiagnosed as dysentery, enteritis, hemorrhoids and bleeding.

matters needing attention

Colon cancer is also a very common malignant tumor in the human body. Generally speaking, the symptoms of colon cancer should be explained by stages, while the symptoms in the middle and late stages are more serious, because it is often accompanied by metastasis, so it is difficult to cure.
