3D medical illustration depicting the TNM stages in breast cancer. Cancer staging can be divided into a clinical stage and a pathologic stage. In the TNM (Tumor, Node, Metastasis) system, clinical stage and pathologic stage are denoted by a small "c" or "p" before the stage (e.g., cT3N1M0 or pT2N0).
This is a step toward tumor progression. [2] [3] In order for a tumor cell to survive, it must decrease its expression of tumor suppressor genes such as p53, BRCA1, BRCA2, RB1, or the fas receptor. [4] [5] A tumor suppressor would trigger an apoptotic pathway in a cancer cell if there were DNA damage, polyploidy, or uncontrolled cell growth.
MRI scans of a patient with astrocytoma, showing the tumor's progression between the incidental finding in 2007 and the onset of phenotypical changes in 2014. Tumor progression is the third and last phase in tumor development. [1] This phase is characterised by increased growth speed and invasiveness of the tumor cells.

This step is important in the metastatic journey as it enables tumor cells to leave their original site and circulate through the body. pro- angiogenic factors like VEGF, [21] along with interactions between cancer calls and the vessel walls, make it easier for tumor cells to penetrate into the bloodstream or lymphatic system.
