What does rectal ca mean

As people's living standards continue to improve, people's diets are also changing. High fat, high sugar, and high salt have become the norm in people's daily diets. There are even some pesticide residues in some vegetables and fruits. These are the main factors that cause intestinal problems and even intestinal tumors. Intestinal CA and rectal CA are very common. Many people don't know much about intestinal tumors. Let's introduce what rectal CA means.

The medical word Ca is the abbreviation of cancer, which means malignant tumor. Hospitals often use this word instead of cancer. For example, liver Ca, lung Ca, metastatic stomach Ca, etc., in order to avoid taboos, after all, some people are still very afraid of the word "cancer". Although patients have the right to know, domestic doctors still try their best to take care of patients and their families, and generally do not write cancer (in the materials that patients can see, such as impact reports, bedside cards, test reports, etc.).

1. Intestinal changes are the most obvious symptom of late-stage rectal cancer: when the disease spreads to the late stage due to various reasons, it will cause certain stimulation to the intestines. As the cancer gradually grows and occupies a larger area, it causes narrowing of the intestinal cavity. When the tumor develops to a certain extent, it will completely block the intestines, resulting in a series of intestinal obstruction phenomena, such as constipation, abdominal discomfort, etc.

2. Lumps appear in the anus and lower rectum: As the tumor develops further, lumps will be felt in the anus and lower rectum, and gradually become more severe. Because the cancer irritates the rectum, the patient's bowel habits will change.

3. Metastasis: When the tumor grows to a certain extent, it will continue to spread to the surrounding tissues. When the spread is serious, it will cause difficulty in urination, and symptoms of urinary pain and frequent urination. When the tumor spreads to the presacral plexus, it will cause pain in the sacral tail and waist. When it spreads to the liver, it will cause liver enlargement, accompanied by jaundice, ascites and systemic cachexia.

4. Increased intestinal secretions: When the tumor irritates the intestinal mucosa, mucus will be attached to the surface of the stool. When the tumor continues to grow and grows to a certain extent, the irritation to the intestinal mucosa becomes more severe. At this time, the patient will experience intestinal discomfort and frequent bowel movements.

The cure rate of rectal CA in the early stage is still relatively high. Biological immunotherapy for rectal cancer can accurately kill residual cancer cells after surgery, improve the effect of radiotherapy and chemotherapy, enhance the patient's immune ability, and better prevent metastasis and recurrence. It can reduce the toxicity and increase the efficacy of radiotherapy and chemotherapy, which is conducive to the smooth progress of radiotherapy and chemotherapy. The whole process of this treatment can be said to be using one's own cells to treat one's own disease, without any harm to the patient's body.
