What are the obvious clinical manifestations of advanced colorectal cancer?

At present, colorectal cancer is the main disease of human life in Weihai. Due to the incorrect diet of modern people, many people have clinical manifestations of colorectal cancer. So, what are the clinical manifestations of colorectal cancer? The following is an introduction to the clinical manifestations of colorectal cancer.

Clinical manifestations of early colorectal cancer : Symptoms appear only after the disease is diagnosed. In fact, patients who have clinical manifestations of colorectal cancer are usually asymptomatic in the early stages. As the tumor grows and the disease progresses, the local lesions often become significantly more serious, even to the clinical manifestations of late-stage colorectal cancer.

Clinical manifestations of advanced colorectal cancer: more obvious symptoms may appear once colorectal cancer enters the advanced stage. However, the clinical manifestations of some colorectal cancers are not specific and are related to the location of the tumor.

1. Right colon cancer is weak. The clinical manifestations of colorectal cancer are mainly indigestion, loss of appetite, diarrhea, constipation, abdominal mass, and progressive anemia. The location of the mass varies with the location of the lesion. In addition, the clinical manifestations of colorectal cancer may include fever, weight loss, and complications such as perforation and localized abscesses. At this time, the lesion has entered the most advanced stage.

2. Left-sided colon cancer forms an acute angle with the rectum. Since the sigmoid colon is narrow and the obstruction is mostly in the lower part of the sigmoid colon, vomiting is mild or absent, while abdominal distension, abdominal pain, bowel sounds and other clinical manifestations of colorectal cancer with obvious intestinal type are present.

3. Rectal cancer: Feces become thinner. The main clinical manifestation of colorectal cancer is increased frequency of bowel movements. It contains blood or mucus, accompanied by tenesmus. Since the tumor can invade the sacral plexus nerves, the clinical manifestation of colorectal cancer may be severe pain.
