A nurse is providing an in-service about cancer.Which of the following statements is true regarding metastasis?
Explanation & Rationale
Choice A rationaleMetastasis is when cancerous cells spread into or invade nearby tissues and can travel to distant places in the body to form new tumors. This process involves the detachment of cancer cells from the primary tumor, their movement through the bloodstream or lymphatic system, and the establishment of new tumors in other parts of the body.Choice B rationaleMetastasis specifically involves cancerous cells, not normal cells. Normal cells do not spread and invade other tissues in a way that causes new tumor formation.Choice C rationaleMetastasis refers to the spread of cancerous cells, not normal cells. Normal cells do not exhibit the same invasive and migratory behaviors as cancerous cells.Choice D rationaleMetastasis involves the spread of cancerous cells, which can lead to the formation of malignant tumors in distant parts of the body. It does not treat tumors but rather contributes to the progression of cancer.
