Don't confuse the clinical manifestations of rectal cancer

The clinical manifestations of rectal cancer are relatively complex and can be easily confused with other intestinal diseases, causing great harm to the patient's health. Now let the experts tell us in detail about the clinical manifestations of rectal cancer .

The main clinical manifestations of rectal cancer are:

1. Changes in bowel habits - Due to the mass and its secretions, intestinal irritation symptoms may occur, such as frequent bowel movements, a 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 the patient may even be unable to fall asleep at night, which changes the previous bowel habits.

2. Blood in the stool - It is one of the most common clinical manifestations 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.

3. Intestinal stenosis and obstruction - This is also a clinical manifestation of rectal cancer. The 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 becomes thinner, defecation is difficult, constipation occurs, and abdominal discomfort, bloating and pain 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 can cause local pain. If it involves the anal sphincter, it can cause anal incontinence, pus and blood in the stool often flow out, and the underwear is contaminated. These are all symptoms of rectal cancer.

5. Other clinical manifestations of rectal cancer - In the late stage of rectal cancer, if it infiltrates other organs and tissues, it can cause symptoms of lesions in those areas. Invasion of the sacral plexus can cause pain in the sacrum and perineum, similar to sciatic pain.
