Colorectal cancer will not be quiet when it comes! Don't ignore these 3 'reminders'
As the saying goes, people are iron rice and steel, and if you don't eat a meal, you will be hungry!
Food is the source of energy for the operation of the body. After a series of operations of the digestive system, they will become various nutrients for human consumption, including protein, vitamins, fats, etc., all from various foods!
However, the food that people eat is not completely absorbed by the body. After they are "squeezed dry" in the small intestine, the remaining food residues will travel with the intestines and accumulate in the large intestine. Next, through the action of coliform bacteria, the intestinal mucosa absorbs the last bit of water and nutrients, and eventually they will become feces, which will accumulate to a certain amount and be excreted from the body!
Therefore, the intestine is the most special existence among all the organs related to digestion. It is responsible for both the absorption of nutrients and the discharge of residues. However, the intestine itself is also very fragile. With the increase of the average age of Chinese residents, the high incidence of chronic intestinal diseases, changes in diet and living structure and other factors, the incidence of intestinal cancer is also "rising"!
Not only the middle-aged and the elderly, but also the young and middle-aged and teenagers have become the targets of colorectal cancer opportunistic attacks. Clinically, there have even been cases of teenage teenagers suffering from bowel cancer, which shows the horror of bowel cancer. What is even more worrying is that because the early symptoms of bowel cancer are not typical, most patients have already reached the middle and late stages when they are diagnosed!
After the middle and late stages of cancer, affected by the spread and infiltration of cancer cells, the effect of later treatment will be greatly reduced, and the survival rate of patients within five years is even less than 20%. This shows the importance of early detection of colorectal cancer.
When the following three symptoms find themselves, beware is the signal of colorectal cancer:
- Disordered bowel habits:
The so-called bowel habit means that I have always had a unique bowel movement pattern, and it has never changed. From a scientific point of view, having more than 2 bowel movements in a week, the stool is formed and easily excreted, which is a manifestation of intestinal health.
However, if there is a sudden change in the stool pattern recently, such as having multiple bowel movements a day, always feeling unclean, tenesmus, or alternating diarrhea and constipation that lasts for more than two weeks and does not improve after taking medication, this is likely to be cancer. Signal. It is related to intestinal cancer stimulating the intestinal mucosa and leading to intestinal dysfunction;
- Changes in stool shape:
The human large intestine itself is a hollow cylindrical body, so when food residues accumulate here, the shape has been fixed into a cylindrical body. Occasionally, the stool is not formed once, and it is often related to eating too much fat and protein food. In addition, intestinal pathogen infection can also cause abnormal stool, such as watery stool is common.
If the shape of the stool changes recently, such as flat strips, small thin strips, or obvious blood marks or sunken marks on one side of the stool, this may be related to the compression of stool by bowel cancer, and it is also one of the most common symptoms of rectal cancer. ;
- Hematochezia:
Blood in the stool caused by colon cancer can be roughly divided into two situations:
The first is melena. Because the patient does not have a lot of bleeding and the bleeding point is far from the anus, after the bleeding, the blood is decomposed in the intestine, and the hemoglobin and sulfide are combined together to form a black tarry stool. stool.
The second type is painless bloody stools, in which blood is mixed with stool and, in most cases, mucus. When bowel cancer induces infection in the body, patients may also have pus-like bloody stools with a strong odor.
The above three symptoms are common symptoms of bowel cancer. The more advanced bowel cancer develops, the more obvious the symptoms will be. However, there are still many patients with bowel cancer who do not have typical symptoms in the early stages of the disease.
Therefore, for patients with a family history of intestinal cancer, family history of intestinal polyps, patients with intestinal polyps, and people over 45 years old, in addition to observing physical symptoms, regular intestinal cancer screening is also necessary.
