What is the disease of rectal cancer?
Colorectal cancer is one of the five most common cancers in the world. The other four types of cancer are lung cancer, breast cancer, prostrate cancer and oral cancer.
These five high-risk cancers, except lung cancer, the remaining four are all malignant tumors of the digestive system. Moreover, experts said that the incidence of gastric cancer, esophageal cancer, and liver cancer has stabilized, but the incidence of colorectal cancer has increased significantly, and there is a trend of rejuvenation.
In 2015, the incidence of colorectal cancer in India accounted for 24.3% of the world’s total, and the number of deaths accounted for 22.9% of the world. Compared with 2005, the number of new cases and deaths have doubled in ten years, reaching 377,000 and 191,100 respectively.
Factor for colorectal cancer increase
In addition to genetic factors, the rejuvenation of colorectal cancer is also an important reason for increased urbanization and changes in the diet structure of the population. Urban white-collar workers under high-intensity work pressure are particularly worthy of attention.
The reason for the rapid increase in colorectal cancer incidence is closely related to the diet structure.
Think about what we usually eat, high-fat, high-protein, high-calorie foods account for a large proportion, and many people are seriously inadequate intake of vegetables and fruits.
Rectal cancer symptoms
The most obvious is blood in the stool. Most other symptoms are also likely to accompany bowel movements, including constipation, thin stools, heavy back pain (despite extreme exertion during bowel movements, the stool is difficult to resolve, accompanied by pain), abdominal pain and so on. However, there are many cases where the cancer is so severe that symptoms do not appear.
In addition, it is not uncommon to mistake rectal cancer for hemorrhoids. Until the abdominal bloating becomes stronger and intestinal obstruction occurs, it is finally found that it is rectal cancer. Take a step back and say that even hemorrhoids can’t be ignored. In fact, this group of people with hemorrhoids is a group with a high incidence of rectal cancer.
If you notice symptoms such as bloody stools or abnormal bowel movements, you must go to the hospital in time for examination.
Most colorectal cancer can be prevented
In addition to genetic immutability, most colorectal cancers can be prevented by changes in lifestyle and eating habits. Especially for digestive tract tumors, the relationship with eating is very close.
Studies have shown that 50% of colorectal cancer in the United States can be prevented by adjusting diet, weight control, and exercise.
Recently, authoritative cancer nutrition experts in the United States have given six ways to prevent colorectal cancer, which can help reduce the risk of colon cancer.
