The blood in the stool caused by rectal cancer will be ignored by people

Blood in the stool caused by rectal cancer is often ignored by people. The color of blood in the stool is basically red or dark red. So do you know what the symptoms of rectal cancer are? This is also a question that people ask a lot. The following authoritative experts will give you a detailed answer.

The symptoms of rectal cancer generally include the following:

1. Blood in the stool is the most common symptom of rectal cancer, but it is often ignored by patients. Blood in the stool is mostly red or dark red, mixed with mucus and blood in the stool, or pus and blood in the stool, sometimes accompanied by blood clots and necrotic tissue. The above symptoms are the result of blood flow obstruction caused by the proliferation of cancer, tissue necrosis and erosion, ulceration and infection, and ulcer formation.

2. Changes in bowel habits Due to the mass and its secretions, intestinal irritation symptoms may occur, such as frequent bowel movements, feeling of no bowel movement, and tenesmus. However, the discharge is mostly mucus, pus, and blood. Initially, these "false diarrhea" phenomena often occur shortly after getting up in the morning, which is called morning diarrhea. Later, the frequency gradually increases, and even the patient cannot fall asleep at night, which changes the previous bowel habits. These are all symptoms of rectal cancer.

3. Intestinal stenosis and obstruction. Cancer infiltrates around the intestinal wall, narrowing the intestinal cavity, especially at the junction of the rectum and sigmoid colon. Most of them are stenotic hard cancers, which are very likely to cause obstruction. Rectal ampulla cancer is mostly ulcerative, and the ampulla is relatively wide. It is estimated that it will take about 1 to 2 years to cause stenosis and obstruction. The stool will become thinner, defecation will be difficult, constipation will occur, and abdominal discomfort, bloating and pain will occur. Due to the accumulation of feces, a cord-like mass can be palpated in the upper part of the sigmoid colon, and sometimes in the left lower abdomen.

4. Anal pain and anal incontinence. If the lower rectal cancer infiltrates the anal canal, it may cause local pain. If it involves the anal sphincter, it may cause anal incontinence, with pus and blood often flowing out and contaminating the underwear. Cancer infection or metastasis may cause enlargement of the inguinal lymph nodes.

The above is the explanation given by experts on the symptoms of rectal cancer. I hope it can help you answer your questions. Experts suggest that some diseases have no early symptoms or are not obvious. For your health, the best way is to have regular physical examinations to detect the disease early and prescribe the right medicine.
