Final answer:
The pathways of cancer metastases for melanoma are within blood. Different types of cancers tend to metastasize to particular organs.
Step-by-step explanation:
The pathways of cancer metastases for melanoma are within blood. Cancer cells can spread from the original site to other tissues in three different ways. One of these ways is through the blood to distant sites, which is called metastasis. The blood can carry cancer cells to various organs, but different types of cancers tend to metastasize to particular organs such as the brain, lungs, bones, and liver.
