Lymphatic spread allows the transport of tumor cells to regional lymph nodes near the primary tumor and ultimately, to other parts of the body. This is called nodal involvement, positive nodes, or regional disease. "Positive nodes" is a term that would be used by medical specialists to describe regional lymph nodes that tested positive for ...

The dispersed tumors are called metastatic tumors, while the original is called the primary tumor. Almost all cancers can metastasize. [39] Most cancer deaths are due to cancer that has metastasized. [40] Metastasis is common in the late stages of cancer and it can occur via the blood or the lymphatic system or both. The typical steps in ...
By promoting these interactions, E-cadherin is able to support cellular motility and aid tumor cells navigate the tissue structures which drives metastasis. [3] [5] Research emphasizes E-cadherin as a major biomarker in metastatic cancers such as breast and colorectal cancers. Low levels of E-cadherin are often linked to poor clinical outcomes ...
Cancer cells are cells that divide continually, forming solid tumors or flooding the blood or lymph with abnormal cells. [1] Cell division is a normal process used by the body for growth and repair.
M describes distant metastasis (spread of cancer from one part of the body to another). The TNM staging system for all solid tumors was devised by Pierre Denoix of the Institut Gustave Roussy between 1943 and 1952, using the size and extension of the primary tumor, its lymphatic involvement, and the presence of metastases to classify the ...

A malignant tumor is defined by its capacity to initiate a biological phenomenon known as the metastatic cascade, a complex multi-stage process in which cell invasion precedes further cancer progression and the formation of metastases in distant organs and tissues. Massive metastatic lesions lead to the development of organ failure.
