Hematogenous metastases are characterized by a lack of clearly defined boundaries - sometimes they resemble small red bumps with blurred contours. Such formations are not always visible on the primary organ and grow into its parenchyma. If we talk about the treatment of hematogenous lesions, it largely depends on their location. Treatment of hematogenous tumor foci is a complex process and requires the use of versatile methods of therapy, which include removal of secondary formations, chemotherapy, and radioirradiation. A lot depends not only on the type of underlying disease, but also on how timely it is detected.

In this case, patients do not even benefit from subsequent surgery, and their prognosis is extremely disappointing. Although long before
