Metastasis is most closely associated with which condition?

Metastasis specifically refers to the process by which cancer cells spread from their original site to other parts of the body. This process is a hallmark of malignant tumors, distinguishing them from benign tumors that do not metastasize. When cancer cells break away from the primary tumor, they can travel through the bloodstream or lymphatic system to establish secondary tumors in other organs. The ability to metastasize is one of the key characteristics that make cancer particularly dangerous, as it complicates treatment and can significantly impact the prognosis. Understanding metastasis is crucial for nursing assistants, as they may be involved in the care of patients dealing with cancer and its systemic effects.

In contrast, conditions such as hypertension, diabetes, and asthma do not involve the mechanism of cancer cell spread and therefore do not relate to metastasis.
