The method is based on the operative removal of the tumor and / or metastases;
The principle of ablastics is important in oncology, that is, when operating, all tumor elements within the healthy tissue are removed. Therefore, surgical treatment of tumor diseases consists in excising the tumor within the healthy tissue together with removal of lymphatic passages and regional lymph nodes. So, the removal of mammary gland is carried out together with the fiber and lymph nodes of the axillary and subclavian areas; stomach resection is carried out with removal of both glands.
Palliative surgical operations
Palliative surgeries are performed primarily to eliminate complications caused by an inoperable tumor of a particular organ in order to restore the vital functions of the body, and not to operate the tumor itself. The second goal of the palliative surgery is a palliative tumor removal, or palliative resection. This type of operation differs from the first one in that it removes part of the tumor tissue (primary tumor or metastases).
