metastasis
Metastasis is the process by which cancer cells spread from the original (primary) tumor to distant parts of the body. This occurs when cancer cells break away from the primary tumor, travel through the bloodstream or lymphatic system, and establish new tumors in other organs or tissues. Metastasis complicates treatment and often indicates a more advanced stage of cancer. Understanding this process is crucial for diagnosing, treating, and managing cancer effectively, as locations of metastasis can significantly impact a patient's prognosis and treatment options.

Metastasis is the process by which cancer cells spread from the original (primary) tumor to other parts of the body. This happens when cancer cells break away, travel through the bloodstream or lymphatic system, and establish new tumors in different organs. Metastatic cancer can be more challenging to treat than localized cancer, as it often indicates that the disease has advanced. Understanding metastasis is crucial in cancer research and treatment, as it influences how doctors approach therapies and predict outcomes for patients.
