What are the symptoms before death from advanced colorectal cancer

When it comes to colorectal cancer, I believe everyone is familiar with it. It is a common and frequently occurring disease that troubles patients' normal lives. Some patients do not take it seriously when they have blood in their stools or digestive discomfort. When the condition becomes serious, they are diagnosed with colorectal cancer and regret it. Below I will introduce the common symptoms and signs of colorectal cancer to you, hoping to help you better understand this disease.

1. In the early stage of colorectal cancer, the main symptom is blood in the stool, followed by changes in bowel habits, a feeling of incomplete defecation, tenesmus, etc. In addition, it is very easy to cause obstruction and intestinal irritation symptoms. Colorectal cancer has many prominent clinical manifestations, and patients need to be more careful. The early symptoms of colorectal cancer are mainly painless blood in the stool, and the blood is red or bright red, which is very similar to the symptoms of early internal hemorrhoids. In the later stage, the blood in the stool is mostly dark red, mixed with mucus and blood in the stool or pus and blood in the stool

2. Secondly, changes in bowel habits are a typical manifestation of mid-to-late stage colorectal cancer. Due to the rectal mass and the secretions it produces, intestinal irritation symptoms may occur, causing the patient to experience symptoms such as frequent urge to defecate, a feeling of incomplete defecation, and tenesmus. However, the discharge is mostly mucus, pus, and blood. At this time, the shape of the stool has also changed, and the stool becomes thinner and thinner.

3. As the cancer infiltrates around the intestinal wall, the intestinal cavity is narrowed, especially at the junction of the rectum and sigmoid colon. Most of them are narrow hard cancers, which can easily cause obstruction. Due to the long-term chronic consumption of the disease, patients with advanced rectal cancer will have some systemic malignant lesions. In addition, unexplained anemia occurs. Unexplained weight loss, fatigue, and loss of appetite, patients must pay attention to it in time and go to a professional hospital for examination and treatment.

4. In the late stage, colorectal cancer often invades surrounding tissues and organs, such as the bladder and prostate, causing frequent urination, urgency and difficulty urinating, invading the presacral nerve plexus, and causing sacral and lumbar pain. Rectal cancer can also metastasize to the liver, causing hepatomegaly, ascites, jaundice, and even cachexia.

From the above introduction, we can know that the clinical manifestations of colorectal cancer are different at different stages of development. In the early stage of colorectal cancer, patients have mucus stool and bloody stool as the main clinical manifestations. As the disease progresses to the middle and late stages of colorectal cancer, patients will have changes in bowel habits. I hope that friends who have the above symptoms will go to the hospital for examination as soon as possible to actively prevent the occurrence of colorectal cancer.
