Rectal cancer is a disease with a high incidence in recent years, which is caused by malignant lesions of rectal tissue cells. Rectal cancer can be triggered by social environment, dietary habits, genetic factors, etc. If left untreated, it will crisis the life of patients. What are the symptoms of early and late stage of rectal cancer? Let’s learn about them together. Early symptoms of rectal cancer Some rectal cancer patients have no obvious symptoms in the early stage of the disease, so it is difficult to be detected by patients. The bowel habits of some patients may change, and the stool characteristics may also be abnormal. Patients with rectal cancer may have mucus or pus and blood in their stools in the early stage, and the number of bowel movements per day may increase, and diarrhea may occur frequently. The stool becomes slightly loose or flat. Patients gradually lose weight and may develop anemia. In addition, systemic symptoms such as abdominal distension, abdominal pain, and loss of appetite may be present. Some patients may find lumps when they feel pressure on abdomen or anus. Symptoms of late stage of rectal cancer 1. When patients with colorectal cancer reach the late stage, an obvious lump can be found in the anus by acupressure. 2. With the development of the disease, the cancerous lump will gradually increase and compress the intestinal cavity, leading to narrowing of the intestinal cavity and obstruction. After the intestinal mucosa is compressed and stimulated, it will produce some irritating secretions, which will be discharged with feces, so some streaks of mucus can be seen in the feces of patients. 3.When the cancer tumor is not ulcerated, the patient often has diarrhea and there is more mucus in the stool. If ulceration occurs, the stool will become very loose or even watery, accompanied by mucus and pus and blood. 4.After rectal cancer, the patient’s bladder tissue will be involved, and the symptoms of difficulty in urination, frequent, urgent and painful urination may occur when urinating. 5.If the cancer invades the presacral plexus, the patient will often feel pain in the lower back. 6.If the cancer metastasizes to the liver, the patient will have a series of liver symptoms, such as hepatomegaly, liver ascites and jaundice, etc. The above are the early and late symptoms of rectal cancer. If early symptoms of rectal cancer are suspected, early examination and treatment should be carried out to effectively prolong life.
