The symptoms of colorectal cancer can develop from early stage to late stage

The symptoms of colorectal cancer can develop from the early stage to the late stage. During this stage, the body's performance may be very significant. So what are the symptoms of colorectal cancer ? This question is also often asked by people. Let the experts explain it in detail.

The symptoms of colorectal cancer mainly include the following:

1. Early Colorectal Cancer

In fact, most patients who have clinical symptoms of colorectal cancer are asymptomatic in the early stages. As the tumor grows and the disease progresses, the local lesions often become significantly more serious, even in the late stages.

2. Advanced Colorectal Cancer

There may be more obvious symptoms of colorectal cancer once colorectal cancer enters the late stage. However, some symptoms are not specific and are related to the location of the cancer.

1. Right-sided colon cancer causes fatigue. The main symptom of this type of colorectal cancer is indigestion. 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 cancer is located in the right lower abdomen, the mass of the ascending colon is located in the right abdomen, the mass of the hepatic flexure of the colon is located in the right upper abdomen, and the mass of the transverse colon is located near the umbilicus. In addition, there may be 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, it is easy to develop stenosis and progressive intestinal obstruction, often with stubborn constipation, and may also be accompanied by an increase in the frequency of bowel movements. Since 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 intestinal patterns are obvious. When the tumor ruptures, the stool may be stained with blood or mucus. The proximal intestinal tract of the obstruction may form ulcers due to persistent expansion, ischemia, and hypoxia, and may even cause perforation. A large amount of blood and abdominal abscesses may also occur.

3. Rectal cancer: Feces become thinner, mainly manifested by increased bowel movements. They contain blood or mucus, accompanied by tenesmus. Since the cancer can invade the sacral plexus, severe pain may occur. If the bladder is involved, symptoms such as frequent urination, painful urination, urgent urination, and hematuria may occur. Cancer invasion of the bladder may form a bladder-rectal fistula. Rectal cancer can also cause intestinal obstruction.

4. Anal canal cancer may cause fecal incontinence. Anal canal cancer can metastasize to the inguinal lymph nodes. The main symptoms of this colorectal cancer are blood in the stool and pain. The pain worsens during defecation. When the cancer invades the anal sphincter, enlarged and hard lymph nodes can be felt in the groin.
