Cancer is one of the three major killers that threaten human life. With the gradual advancement of science and technology, people's life pressure is gradually increasing, so more and more people are suffering from cancer. There are many types of cancer, generally classified according to the location of the cancer, such as rectal cancer. So, can rectal cancer in general be cured?

1. What is rectal cancer

Rectal cancer is a common malignant tumor in the gastrointestinal tract. Its incidence is second only to gastric cancer and esophageal cancer. It is located in the dentate line Cancer between the junction of the sigmoid colon and the rectum. Common symptoms include: blood in the stool, frequent urination, urgency, dysuria, hematuria, urination disorders, fatigue, weight loss, anemia, weight loss, etc.

2. Causes of rectal cancer

The specific cause of rectal cancer is still not very clear, but most believe that it is related to the following factors:

1. Diet Factors: High-fat, high-protein and low-fiber foods are considered by Western countries to be closely related to the occurrence of rectal cancer. This is because high-fat and high-protein foods can increase carcinogens in the feces and weaken intestinal peristalsis, thereby increasing the chance of rectal cancer.

2. Cancerous adenoma: Neoplastic polyps in the rectum may also become cancerous. They mainly include tubular adenoma, villous adenoma and mixed adenoma. These adenomas are also one of the risk factors for rectal cancer.

3. Genetic factors: In most families of rectal cancer patients, there are also patients with cancer. The main reason is that the patient with cancer inherits a type of disease in the next generation, and due to certain stimulating factors, the tissue cells grow rapidly and develop into cancer.

4. Inflammatory bowel disease: Ulcerative colitis and Crohn's disease are caused by damage to the intestinal mucosa, ulcer repair and proliferation, canceration during the formation of granulation tissue, deposition of schistosomiasis eggs in the rectal mucosa, and chronic inflammation. Stimulates carcinogenesis.

3. People prone to disease

1. People over 50 years old: People with rectal cancer have certain concerns with age. As age increases, various causes The time that pathogenic factors irritate the rectal mucosa also increases. Generally, people over 50 years old have a higher chance of suffering from rectal cancer.

2. Family history: People with a family history of rectal cancer are also at high risk of rectal cancer.

3. History of colon inflammatory diseases: Certain colon diseases such as Crohn's disease or ulcerative colitis may increase the chance of colorectal cancer.

4. Colorectal polyps: Many rectal cancers develop slowly from small precancerous lesions, often called polyps. People with polyps also develop rectal cancer. One of the high-risk groups.

4. Can rectal cancer be cured?

There is no definite answer to whether rectal cancer can be cured. The treatment of rectal cancer mainly depends on the severity of the disease, the patient’s physical fitness, and psychological well-being. It depends on a variety of factors including factors and specific treatment circumstances. With the advancement of medical technology, patients with early-stage rectal cancer can be cured with a certain probability through surgery and post-operative consolidation treatment.

5. Commonly used dietary prescriptions for rectal cancer

1. 50g each of purslane and eggs, or an appropriate amount of kiwi fruit. 50g per day, made into food for year-round consumption. It has auxiliary therapeutic effect on colorectal cancer patients.

2. 30g day lily, 15g fungus, 6g blood charcoal. Decoct the first two kinds of water to get 300ml of juice, and drink the remaining charcoal with blood. You can also take fresh figs regularly. It has a therapeutic effect on patients with intestinal cancer who have bloody stools.

3. For patients with colorectal cancer and obvious anemia, 30g of black fungus and 30 red dates can be made into food for one day and eaten every day.

4. For patients with leukopenia after radiotherapy or chemotherapy, porridge can be cooked with barley rice, gordon fruit, water chestnut, lotus seeds, etc. and eaten regularly. Or eat more shiitake mushrooms, oyster mushrooms, mushrooms, black fungus, white fungus, etc., which can increase white blood cells and enhance the body's immunity.

6. Patients with rectal cancer should pay attention

Whether they have rectal cancer or not, they must pay attention to their eating habits, not be partial or picky about food, and do not eat high-fat or high-protein diets for a long time. , often eat fresh vegetables containing vitamins and fiber to prevent constipation and keep stool smooth. Develop good living habits, quit smoking and limit alcohol consumption. Do not eat too much salty and spicy food, and do not eat food that is too hot, too cold, expired or spoiled.

7. Early symptoms of rectal cancer

1. Blood in the stool

Basically half of the patients with rectal cancer will have bloody stools In this case, this kind of bloody stool often only covers the surface of the stool, and the color is bright red or dark red. When the cancer only involves the surface of the mucosa, symptoms such as hepatic distension or itching often occur; when the cancer invades below the mucosa, bloody stools will occur. This kind of bloody stools has a small amount of intermittent bleeding and is mostly bright red or Dark red blood.

2. Mucus in the stool

In rectal cancer, there is a cauliflower-shaped tumor mass and inflammatory lesions of the intestinal mucosa, which can cause a large amount of mucus secretion, forming Mucus stool, if gas is mixed with mucus stool, the stool will be foamy. Cancer lesions will be combined with surrounding infections and produce a large amount of pus. At this time, they are often misdiagnosed as chronic enteritis or dysentery. If the surface of the cancer erodes or forms ulcers, symptoms include more bleeding, thin stools, increased pus and blood, and a bloody odor.

3. Changes in the frequency of defecation

Changes in defecation habits are also among the early symptoms of rectal cancer. Normal people's bowel movements are relatively regular, usually once in the morning. Patients with rectal cancer experience irregular changes in defecation frequency, defecation time, and defecation quantity. For example: Rectal papillary cancer often presents with diarrhea and frequent bowel movements due to excessive mucus; ring-shaped hard cancer often presents with constipation symptoms at the earliest, and later begins to cause loose stools and diarrhea.

4. Rectal chasing sensation

When the cancer in the rectal ampulla is large or invades surrounding tissues, clinical symptoms such as anal prolapse and incomplete defecation may occur. Because ampullary cancers are mostly cauliflower-shaped, secretions mixed with pus and blood often flow out of the anus.

5. Abdominal pain

Abdominal pain is one of the early symptoms of a small number of patients with rectal cancer. Cancer of the upper rectum or sigmoid colon may form annular stenosis, intestinal obstruction, etc., and often manifest paroxysmal abdominal cramps, accompanied by symptoms such as abdominal pain, hyperactive bowel sounds, thin stools, and reduced anal exhaust. These symptoms There is a certain degree of relief or disappearance after defecation.
