Introduction to the four most common ways colon cancer metastases

It is understood that almost all malignant tumors will metastasize in the late stage, and colon cancer is no exception. Colon cancer metastasis will occur in the late stage, which will have a great adverse effect on the patient's condition. So what are the common ways of colon cancer metastasis ? Let's talk about the common ways of colon cancer metastasis.

In general, common ways of colon cancer metastasis are:

1. Direct infiltration: It usually infiltrates in a circular pattern along the horizontal axis of the intestine and develops into the deep layer of the intestinal wall. It spreads slowly up and down along the longitudinal axis. It is a common way for colon cancer to metastasize. After the cancer invades the serosa, it often adheres to the surrounding tissues, adjacent organs and peritoneum.

2. Lymphatic metastasis: This is the main way for colon cancer to metastasize. It usually spreads from near to far, but there are also non-sequential metastases. The chance of lymphatic metastasis increases after the tumor invades the intestinal wall muscle layer. If the subserous lymphatic vessels are invaded, the chance of lymphatic metastasis is even greater.

3. Hematogenous metastasis: Generally, cancer cells or cancer thrombi first reach the liver along the portal vein system, and then reach other tissues and organs such as the lungs, brain, and bones. This is also a way of colon cancer metastasis.

4. Peritoneal implantation and metastasis: Cancer cells fall off in the intestinal cavity and can be implanted on mucosa elsewhere. If they fall off in the abdominal cavity, colon cancer metastasis can be implanted on the peritoneum.

The above is an introduction to the common ways in which colon cancer metastasizes. I hope it will be helpful to everyone. If colon cancer metastasizes, you must face treatment more actively to prevent the disease from further worsening and causing more serious damage.
