What are the common clinical characteristics of colorectal cancer

The incidence of colorectal cancer is increasing year by year, and the mortality rate is high. The 5-year survival rate is closely related to the Dukes stage. Most early colorectal cancers have no obvious symptoms, or only show symptoms of precancerous lesions. However, as the lesions progress, a series of symptoms and signs may appear. Next, let's learn about the common clinical characteristics of colorectal cancer:

1. The early diagnosis rate is very low. Among the young people diagnosed with colorectal cancer, 50% to 80% are already in the middle or late stages, and patients under 20 years old, once diagnosed, are almost all in the middle or late stages.

2. High degree of malignancy. The worse the differentiation of cancer, the higher the malignancy. Among the colorectal cancers diagnosed in young people, the poorly differentiated mucinous adenocarcinoma accounts for 50% to 60%, which is 3 to 6 times that of elderly patients; in patients under 20 years old, mucinous adenocarcinoma accounts for 80% to 90%.

3. Prominent pain symptoms and easy bleeding. Since most patients are in the late stage when they seek medical treatment, they are prone to acute intestinal obstruction, so about 40% of patients have abdominal pain as the first symptom. As for bleeding, most patients will not pay attention to it and will treat it as hemorrhoids for a long time, causing delays in the disease.

4. A high proportion of female colorectal cancer patients have ovarian metastasis. According to a data, the ovarian metastasis rate is as high as 12% among young women diagnosed with colorectal cancer, and 1/3 of the patients come to the hospital for ovarian tumors.

5. Long diagnosis time. Generally, it takes about 5 to 10 months for young colorectal cancer patients to be diagnosed after symptoms, which directly leads to the delay of the disease.
