There are two performances in an organ?

The same organ and long tumor early warning signals in different parts are also different, only because the tumor has changed "retrograde". "Health Hall" will tell you how to seize the trajectory of retrograde tumors and answer the following questions for everyone.

1. Why is the incidence of colorectal cancer in the elderly?

In recent years, with the increase of my country's population aging, one of the reasons for the proportion of intestinal cancer in elderly elderly women is that estrogen is a protective factor for inhibiting the occurrence and development of colorectal cancer. As women's age continues to increase, the level of natural estrogen in the body has decreased year by year, and the protection of estrogen has weakened year by year. Therefore, the incidence of women's colorectal cancer in my country has a tendency to increase year by year.

2. Why does the left half of the colon and the right half look like an organ, but it shows the performance of the two organs?

Both the right half colon cancer and the left half of colon cancer are colon cancer, but there is a difference between the two. The main manifestations are: first, the two types of colon cancer are different, which means that they are different from the mother's fetus. The right half of colon cancer is mainly derived from the midst layer, and the left half colon cancer mainly originated from the outer embryo. Second, the early warning signals of the two are different. Because the diameter of the right half of the colon is relatively wide, the obstruction caused by the right half colon cancer is extremely rare. Essence The left half of the colonic tube is relatively narrow. Therefore, the left half colon cancer is mainly manifested in the changes in the traits of the stool and the bowel habits. In addition, in terms of internal medicine treatment, the sensitivity to targeted drugs is also different.

3. Why does the left half of colon cancer have symptoms of constipation and diarrhea alternation?

Symptoms of diarrhea and constipation of colorectal cancer are a very typical clinical manifestation. Some people think that these two opposite diseases will not appear on a person at the same time, so they do not care about it, do not cause sufficient vigilance and delay the condition. In fact, when a "occupying lesions" occur in a certain part of the intestine, it will stimulate the "plant nerve" that regulates the intestine. The plant nervous system impulse these continuous stimulus signals to the cerebral cortex. After a long time, it can cause the regulatory dysfunction of the cerebral cortex. When the plant nerves excitement stimulates the intestinal movement, and the patient has diarrhea; however, the nerve excitement will gradually decline and change due to "fatigue". The intestinal muscles slowly relaxed, the peristalsis weakened, and caused constipation. Such patients often discharge very thin stool or sheep dung egg -like stool. The spasm of the colon continued to deepen, the intestinal peristalsis increased, and the stool changed from constipation to diarrhea. Therefore, patients with disorders of intestinal movement will occur, sometimes constipation, sometimes diarrhea, or constipation and diarrhea alternate. If the above situation has occurred in the near future and is accompanied by other symptoms, such as blood in the stool, weight loss, fatigue, anemia, changes in the shape of the stool, etc., we must pay attention to it and seek medical treatment as soon as possible.

The progressive or advanced colorectal cancer can cause edema of the lower limbs of the patient, similar to the edema caused by renal or heart disease. If there is an unknown cause and is not caused by the edema caused by abnormal heart and kidney function, it must be alert to whether colorectal cancer has developed to the middle to the middle. Late. Due to tumor ulcers and blood loss and toxin absorption, the patient may have symptoms similar to "poisoning". Low fever is a obvious signal. So what is the difference between this low fever and low fever caused by fever and fever? Is it black tea or green tea more conducive to protecting the intestine?

So how many times are healthy people in daily life? Because the individual is differentiated, under normal circumstances, it is normal for a person to 1-3 times a day or about 4-7 times a week. But if there are more than five or six times a day, this is enough to suggest that there are some problems with your intestine. How should we judge and deal with at this time? Please lock up the "Health Hall" broadcast today at 17:25.
