Cancer Metastasis
Cancer metastasis is the process by which cancer cells spread from their original (primary) site to other parts of the body. This occurs when cancer cells break away from the primary tumor, travel through the bloodstream or lymphatic system, and form new tumors (metastases) in distant organs or tissues. Metastasis complicates cancer treatment and affects prognosis, as the spread can impact vital functions and make the disease harder to manage. Understanding this process highlights the importance of early detection and treatment, as localized cancers are often more treatable than those that have metastasized.

Cancer metastasis is the process by which cancer cells spread from the original tumor to other parts of the body. Initially, these cells can invade nearby tissues. Over time, some may enter the bloodstream or lymphatic system, allowing them to travel to distant organs. Once they reach a new site, they can grow and form new tumors. Metastasis complicates treatment and is often a sign that the cancer is more advanced, making understanding this process vital for effective management and care.
