Final answer:
The term for cancer that has spread to other organs is 'metastasis,' with the resulting tumors called 'metastases.' These most commonly occur in the brain, lungs, bones, and liver, and are associated with a worse prognosis.
Step-by-step explanation:
The term best associated with cancer that has spread to other organs of the body is metastasis. When cancer cells travel through the bloodstream and create new tumors in different parts of the body, these are known as metastases. Common sites for metastases include the brain, lungs, bones, and the liver.
During the late stages of the disease, almost all cancers can metastasize, making treatment and management more challenging. The occurrence of metastasis is typically associated with a poorer prognosis and is a leading cause of cancer-related deaths.
Tissues and Cancer can summarize the nature of cancer: It involves uncontrolled cell growth, tissue invasion, and sometimes the colonization of other organs, leading to significant health issues when normal organ functions are impaired by the growing tumors.
