What harm does rectal cancer bring

What harm does rectal cancer bring? Rectal cancer is not uncommon in life. It is a cancer with a relatively high incidence rate in clinical practice. Nowadays, many people cannot pay attention to their health in time, so the number of people suffering from rectal cancer is increasing. So, what harm does rectal cancer bring?

First, bloody stools: bloody stools are common symptoms in patients with rectal cancer. The cause of rectal cancer in middle-aged and elderly people is mostly on the left side. After bleeding from the tumor, fresh bloody stools can be seen with the naked eye. Rectal cancer in young people often appears on the right side. Since the stool has not yet formed in the right half of the colon, the stool is mixed after bleeding and a fecal occult blood test is required.

Secondly, cancer: Among middle-aged and elderly patients with rectal cancer, more than 70% of patients develop colorectal cancer in the left rectum, sigmoid colon and descending colon. Most colorectal cancers in young people occur in the right cecum and ascending colon. Generally, the right half of the large intestine has poor fixation, greater mobility and a wider intestinal cavity, so naturally the cancer is more mobile and generally does not occur. Tumors on the left side are more fixed and prone to intestinal obstruction.

Furthermore, survival rate: rectal cancer in young people is more likely to spread, generally to surrounding or deep tissues, and has a poor prognosis. The 5-year survival rate of rectal cancer in young people is often only 1/4 of that of middle-aged and elderly rectal cancer patients. Rectal cancer is more harmful to young people.

Finally, abdominal pain: Young people with rectal cancer have a faster progression of the disease, and the cancerous lesions are prone to infiltrate the serosal layer, which is prone to lesions and inflammation. Young patients usually experience severe abdominal pain. Middle-aged and elderly people have aging organs and are generally less sensitive to pain, so abdominal pain is less severe.

There are many dangers of rectal cancer. The most obvious ones are bloody stools, tumors, abdominal pain, etc. In addition, the survival rate of young people with rectal cancer is not high, and the harm is even greater. This requires young people to know more about the symptoms of rectal cancer so that they can detect and treat the disease early.
