Metastasis Distant

*Distant metastases* is a new look at the spread of a tumor at a non-operable stage due to the fact that removing the source of this tumor will be impossible or impractical. - This can apply to both invasive processes and tumors with infiltrative growth (for example, medulloblastoma, pancreatic cancer, etc.).

It should also be noted that we are talking about the fact that the appearance of the spread of a malignant tumor in remote/distant parts of the body is secondary after the main surgical intervention or chemotherapy and radio irradiation.

Metastases are distant metastatic foci that form as a result of malignant tumor cells migrating from the site of initial localization to other organs or tissues. In this article we will look at what METASTASIS is, how it forms and how it can affect the patient’s health.

Metastases occur because cancer cells that have failed to kill the patient's immune system can spread to other parts of the body through the blood or lymph. Most often, metastases occur in the lungs, liver, bones, brain, lymph nodes and other organs.

There are several reasons for the formation of metastases:

1. Cancer could not defeat the immune system. The immune system plays an important role in the fight against cancer. If the cancer could not resist it in the early stages, then the immune system may have a chance to succeed and the cancer will be defeated. 2. The presence of favorable conditions for the proliferation of cancer cells. Such conditions may include increased estrogen levels, increased thyroid hormone levels, or increased prolactin levels in a woman's body. 3. Failed chemotherapy or radiation. If a man has a cancerous tumor in his body that is treated with chemotherapy or radiation, then cancer cells may migrate to the liver. This may cause METASTASIS. 4. Distribution throughout the system. Common metastases are very common in patients. When a patient has metastasis
