What is the cause of cancer metastasis?

summary

If you find that you have cancer, most people's reaction is to have surgery as soon as possible. In fact, the specific treatment depends on the patient's condition. The recurrence and metastasis of cancer after surgery is a great risk for cancer patients. Many patients usually choose surgery to remove the focus after diagnosis, but surgery can not guarantee complete resection, So there is the risk of recurrence and metastasis, when the disease recurrence and metastasis, the patient's body is undoubtedly worse. What is the cause of cancer metastasis? Let's talk about it

What is the cause of cancer metastasis?

Due to the continuous invasive growth of cancer cells in the body, the density of local cells increases, and the ability to squeeze adjacent tissues is great. Moreover, due to the decrease of calcium content of cancer cell membrane, the binding force between cells decreases, and it is particularly easy to separate from each other, which creates conditions for the invasion or dissemination of cancer cells.

In addition, some cancer cells have certain activity and can release some diffusion factors, such as hyaluronidase, which can dissolve the mucopolysaccharide in the matrix, which also plays a role in promoting the invasion and metastasis of cancer. The occurrence of metastasis is also related to the degree of differentiation of cancer tissue.

Cancer is easy to metastasize to organs with abundant blood supply, such as bone, liver and lung. In addition to the characteristics of cancer itself, the occurrence of metastasis is also related to the state of the patient's body. Patients with poor general condition or low immune function can increase the chance of cancer metastasis.

matters needing attention

Now there are no non-surgical treatment, chemotherapy and radiotherapy for tumor patients, but after these treatments, the condition of tumor patients will be more and more serious, and will form a diffusion phenomenon. Because the operation will lead to the deficiency of Qi and blood in the human body, that is, after a part of Qi and blood is scattered, the immunity will be significantly reduced, and it is easier to form the diffusion phenomenon at this time.
