Etymologically, metastasis is a word of Greek origin "metatastis" which means to move. Metastasis is a term that is used in the medical area to refer to the reproduction of a cancerous nucleus in another organ different from the one where it originated, this frequently happens through the bloodstream, and according to studies, almost 98 % of people who die from non-localized cancers are due to their metastasis.
Metastasis is the ability to allow cancer cells to enter the blood vessels and lymph, move through the bloodstream, and then settle on a new core, developing in healthy tissue from another part of the body of the person. When a tumor appears within a person's body, it can be benign or malignant, its difference will depend on whether they can penetrate locally or metastasize to other organs that are far apart.
When tumors are benign, it is because they cannot spread by incursion and metastasis, which is why they only develop locally, now well, now, when tumors are malignant it is because they have the ability to spread by incursion and metastasis, for what when a person is diagnosed with cancer, is because a malignant tumor is present inside his body.Once the cancer is diagnosed, the specialist must perform a series of tests to determine if the tumor is located in a single point or has metastasized to other organs.
Metastasis usually occurs in organs with the highest blood supply, such as the brain, liver, lungs, adrenal gland, and bones, with the exception of the heart and kidneys. On the other hand, there are some tumors that are prone to spreading in certain organs. For example, there is colon cancer, which can spread to the liver, there is also stomach cancer, which commonly spreads to the ovaries, in the case of women.
It can be said that the cancer that has the most metastasis is that which appears in the breasts and in the lung. When the cancer has metastasized, the most recommended by specialists is the performance of chemotherapies, radiotherapies, biological therapies, surgeries, any of these treatments will depend on the type of cancer that the person presents, the size of the tumor, where it is located metastasis, age and health of the patient.
