Metastatic Cascade

The metastatic cascade describes the process by which cancer spreads from its original site to other parts of the body. It involves several steps: cancer cells break away from the primary tumor, invade nearby tissues, enter blood or lymphatic vessels, travel through these channels, exit into new tissues, and then establish new tumors. This process allows cancer to metastasize, or spread, making treatment more complex and challenging. Understanding this cascade helps researchers develop strategies to prevent or interrupt the spread of cancer.
