What is the classification of early colorectal cancer

In recent years, colorectal cancer has become one of the major diseases that endangers society and human health, and it has brought great pain and distress to humans. In order to reduce the incidence of colorectal cancer, we humans should master the classification of early colorectal cancer:

1. Early colorectal cancer: Cancer that is limited to the colorectal mucosa and submucosa is called early colorectal cancer. Generally, there is no lymph node metastasis. However, among those infiltrating into the submucosa, 5% to 10% of cases have local lymph node metastasis. Early colorectal cancer is divided into 3 types based on naked eye observation.

(1) Polypoid type: The appearance shows localized protrusion of the mucosa, which may be pedunculated, subpedunculated, or broad-based. This type is often intramucosal cancer.

Gross classification of colorectal cancer (2) Flat raised type: The mucosa is slightly thick, almost normal, with no protrusions on the surface, or slightly raised, like a coin.

(3) Flat bulge with ulceration; like a small disc, with raised edges and a sunken center. Only seen in submucosal cancer.

The above is the early classification of colorectal cancer. I hope everyone will pay attention to it. Expert Tips: If you have symptoms of disease, do not delay diagnosis.
