What are the symptoms and manifestations of advanced colorectal cancer

The early symptoms of colorectal cancer are not very obvious. When the tumor grows to a certain extent, some more obvious symptoms will appear. Generally, when the tumor develops to the middle and late stages, the symptoms will be obvious. So what are the symptoms and manifestations of late-stage colorectal cancer? Please give us a brief introduction.

1. Increased secretion When the tumor grows to a certain extent, the intestinal mucosa is stimulated, resulting in increased secretion, and a small amount of mucus is discharged with the stool, which indicates that it is a symptom of mid-to-late stage rectal cancer. Sometimes constipation occurs, but it is not caused by intestinal stenosis. As the tumor continues to develop, the stimulation to the rectal mucosa gradually increases, and the patient feels slight discomfort in the rectum, or has a sense of emptiness and defecation, and the mucus secretion increases, and strips of mucus appear on the surface of the stool. Diarrhea often occurs before the cancer ulcers, and the stool contains more mucus. When the cancer ulcerates, the stool becomes thinner, such as watery or even contains mucus and blood.
2. Changes in bowel habits When intestinal cancer develops to the middle and late stages, the patient's bowel habits begin to change, and the patient often experiences symptoms such as bloody stools, tenesmus, bloody stools, or constipation and diarrhea.
3. Cancer invasion Once the cancer invades the adjacent tissues, it may cause the patient to have symptoms of dysuria, dysuria and frequent urination. If the malignant tumor invades the presacral nerve plexus, lumbar pain and sacral symptoms may occur. When the cancer metastasizes to the liver, the symptoms of mid-to-late stage colorectal cancer include hepatomegaly, jaundice, ascites and cachexia.
4. Masses Doctors can find masses through rectal examination. Many patients are found through rectal examination. Hard, uneven masses can be touched. In late-stage patients, the intestinal cavity is narrow and the masses are relatively fixed. Dirty pus and blood containing feces can be seen on the gloves of intestinal examination.
The above is a brief introduction by experts on the symptoms of mid- and late-stage colorectal cancer. I hope it will be helpful to you. Cancer treatment is a long and drawn-out process. In addition to taking good care of the patient's diet and life, the patient's family should also encourage the patient to maintain an optimistic and positive attitude, actively fight cancer, and strive to maximize life extension and improve the quality of life.
