Colorectal "polyps" and colorectal cancer, the so-called "polyps", refers to the intestines (mucosal surface) grow out of a variety of protuberances. From the medical point of view, this kind of polyp is divided into tumor and non tumor. The former is called "adenoma", which is a true benign tumor. The latter polyp is not a tumor. In fact, not all adenomas need to become cancer. The most likely to become cancer is the "familial adenomatous polyposis" mentioned above. This kind of adenoma can have abdominal pain, diarrhea, bloody stool, or no symptoms. It can not be found until after canceration.

Usually what we call colorectal tumors include benign and malignant. Benign tumors of the large intestine, also known as "adenomas", are hyperplastic glands (mucous secreting tissues in the large intestine). This is a benign tumor that does little harm to human body. But because it has the possibility of further developing into cancer, it is called "precancerous lesion" in medicine. Once this kind of tumor is found, although it is not a malignant tumor, it should be actively treated and reexamined.

The main symptom of colorectal cancer is bloody stool, followed by diarrhea, anemia, abdominal pain, weight loss and so on. Once these symptoms appear, you should go to the hospital immediately. According to the statistics of domestic cases, the misdiagnosis rate of colorectal cancer is as high as 41.5%. One of the important reasons is the lack of understanding of the symptoms of colorectal cancer, which delays the treatment. There are also some cases due to the lack of vigilance of doctors, neglect of careful examination, mistake bloody stool for hemorrhoids, treat purulent bloody stool as dysentery. It has been analyzed that the time from symptom to diagnosis of colorectal cancer patients is: only 810% of the patients are diagnosed within one month, 25% within one to three months, and 64.3% within 36 months.
