Analysis of four common ways of colon cancer metastasis

Colon cancer metastasis is a common phenomenon in the late stage of colon cancer, which brings great difficulties to the treatment of colon cancer and causes great harm to colon cancer patients. What are the common ways of colon cancer metastasis ? Let's talk about the common ways of colon cancer metastasis.

In general, the common ways of metastasis of colon cancer are:

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

2. 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 common way for colon cancer to metastasize.

3. Direct infiltration: This type of colon cancer metastasis is to infiltrate in a circular pattern along the horizontal axis of the intestine and develop into the deep layer of the intestinal wall, while spreading slowly up and down along the vertical axis. After the cancer invades the serosa, it often adheres to the surrounding tissues, adjacent organs and peritoneum.

4. Peritoneal implantation and metastasis: Cancer cells fall off in the intestinal cavity and can be implanted on mucosa elsewhere, or fall off in the abdominal cavity and can be implanted on the peritoneum. This is also a common way of metastasis of colon cancer.

The above is an introduction to the common ways of colon cancer metastasis. I hope it will be helpful to everyone. Once you have colon cancer, you must go to the hospital for treatment immediately to avoid delaying the disease.
