What are the dangers of rectal cancer

What are the dangers of colorectal cancer? Every disease will cause harm to people's bodies, which is also a key reason why people are afraid of diseases. I believe that many people are familiar with colorectal cancer. This disease is actually a common digestive tract disease. So how much do you know about the specific harm it brings to people? Let us introduce it to you in detail.

1. Bloody stool or blood in stool

Most of them are manifestations of advanced rectal cancer. At this time, as the tumor grows larger, the blood supply is relatively reduced, so the tumor ruptures and bleeds. The patient may frequently discharge blood every day, sometimes more than 20 ml at a time. Due to the increased frequency of bowel movements, the patient may have difficulty sleeping day and night, lose appetite, and the patient's condition is very poor, sometimes showing a cachectic state.

2. Pain in the perineum

As rectal cancer develops, it can invade the tissues around the rectum, causing irritation of the lumbosacral nerves and pain in the anus and lumbosacral region. This pain is often persistent and sometimes very severe, making it difficult for the patient to sleep day and night. It can radiate to the waist and back or to the lower limbs along the sciatic nerve. This pain is often persistent and does not disappear with bowel movements, indicating that the tumor has extensively affected the pelvic wall tissues.

3. Decreased appetite, weight loss, and anemia

Late-stage tumors show persistent chronic wasting changes, coupled with tumor bleeding, so most patients are anemic, and sometimes patients are in a cachectic state. This condition is difficult to correct, and some patients die of exhaustion.

Through the above reading, everyone should know that the harm of rectal cancer is actually very serious, so it is recommended that friends must develop good living habits.
