Metastasis

Metastasis (from the ancient Greek “movement”) is the formation of secondary tumor foci that arise as a result of the spread of tumor cells from the primary focus to other organs and tissues of the body.

Metastasis is one of the main properties of malignant tumors. In this case, tumor cells are separated from the primary tumor and spread by lymphogenous, hematogenous or implantation routes.

The formation of metastases indicates the generalization of the tumor process and the transition of the disease to a more severe stage. The presence of distant metastases often complicates treatment and worsens the prognosis.

Prevention of metastasis includes timely detection and treatment of primary tumors. The fight against metastases is one of the main tasks of oncology.

Metastasis is one of the most common and dangerous complications of cancer. This is the process by which cancer cells spread from the primary tumor site to other parts of the body. As a result of this process, new tumors and metastases may arise, which can lead to serious consequences.

Metastases can occur in a variety of organs and tissues, including the lungs, liver, brain, and bones. This can lead to the development of symptoms such as pain, cough, shortness of breath, weight loss, weakness and others.

Treatment of metastases can be complex and requires a comprehensive approach. It usually includes chemotherapy, radiation therapy, surgical removal of the tumor and other methods. In some cases, a bone marrow or other organ transplant may be required.

It is important to remember that early diagnosis and treatment of metastases can significantly improve the prognosis of the disease and increase the chances of survival. Therefore, it is important to undergo regular examinations and consult a doctor if any suspicious symptoms appear.
