Final answer:
The correct term for cancer that has spread to other organs is metastasis. It describes the formation of secondary tumors, known as metastases, which occurs when cancer cells travel from the primary tumor site to other parts of the body.
Step-by-step explanation:
The term that is best associated with cancer that has spread to other organs of the body is d. Metastasis. Metastasis occurs when cancer cells break away from the original (primary) tumor and travel through the bloodstream or lymphatic system to form new tumors in other organs. These secondary tumors are known as metastases. Malignant tumors are cancerous growths that have the potential to metastasize, unlike benign tumors, which do not spread and are typically not harmful.
