What is mentastasis?

Metastasis is the process by which cancer cells spread from the original (primary) tumor to distant parts of the body, forming new (secondary) tumors. This occurs when cancer cells break away, travel through the bloodstream or lymphatic system, and invade other tissues or organs. Metastatic cancer is generally more difficult to treat and can significantly impact prognosis. Understanding metastasis is crucial for developing effective cancer therapies and improving patient outcomes.
