Final answer:
Metastasis is the spreading of cancer cells from the original tumor to other areas in the body. Cancer cells can travel through the bloodstream to distant sites and form new cancers, called metastases. Different types of cancers tend to metastasize to specific organs.
Step-by-step explanation:
The spreading of cancer cells from the original tumor where they were produced to other areas of the body is called metastasis. During metastasis, cancer cells can travel through the bloodstream to distant sites and form new cancers, or metastases. Different types of cancers tend to metastasize to particular organs, such as the brain, lungs, bones, and liver.
