What are the symptoms of rectal tumors? Early symptoms of rectal cancer

In life, only by having a certain amount of disease knowledge can we prevent or avoid the occurrence of some diseases, so it is very important to reserve some basic knowledge. So what are the early symptoms of rectal tumor?

1. Blood in the stool: It is the earliest and most common manifestation of colorectal cancer. In mild cases, there is only occasional bleeding, which requires laboratory testing to detect. In severe cases, there may be mucus and blood in the stool, mucus and blood in the stool, or fresh blood in the stool, which is often misdiagnosed as dysentery or hemorrhoidal bleeding, thus delaying the timing of diagnosis. The amount and nature of bleeding vary depending on the location of the cancer, and long-term bleeding can cause secondary anemia.

2. Abdominal pain: Some patients have persistent, inaccurately located dull pain as the first or prominent symptom, while some patients only have abdominal discomfort or bloating. When colorectal cancer is combined with erosion, obstruction or secondary infection, obvious abdominal cramping may occur due to increased peristalsis and spasms of the corresponding intestinal segments. Some patients present with typical incomplete intestinal obstruction abdominal pain, that is, the pain is paroxysmal cramping, lasting for several minutes, and they feel gas passing through the pain, followed by gas discharge, and then the pain suddenly disappears. When this symptom occurs in the elderly, colorectal cancer should be considered first.

3. Changes in bowel habits: Mostly changes in bowel movement frequency or stool characteristics, such as bowel movements once a day, but now 3-4 times a day for unknown reasons, or alternating diarrhea and constipation, and changes in stool shape, which used to be soft and formed, but now suddenly become watery, and there seems to be blood or pus in them, which reminds you that there may be problems in the intestines and you should go to the hospital for a checkup. (It should be pointed out that these symptoms are also common in other diseases, so if you have the above symptoms, you should have a comprehensive physical examination.) Some people also have a feeling of urgency and heaviness in the bladder, especially when it occurs in young people. If you often have intestinal disorders such as constipation and diarrhea without any other reasons (including travel, changes in living environment, and taking oxytetracycline), and regular treatment for more than two weeks is still ineffective, you should pay attention, as it may be an early sign of colorectal cancer.

4. Anemia: Male patients, especially those without other causes of blood loss and intestinal parasites, should be considered for the possibility of stomach or colon cancer if they are found to have progressive iron deficiency anemia.
