Final answer:
Cancer metastasis involves invasion, intravasation, transport, extravasation, and colonization, allowing cancer cells to spread and form new tumors in distant organs.
Step-by-step explanation:
The steps involved in cancer metastasis are D) Invasion, intravasation, transport, extravasation, and colonization. This process begins with invasion, where cancer cells penetrate into neighboring tissues. Next, intravasation occurs, with cells entering the bloodstream or lymphatic system.
The cancer cells are then transported through the circulatory or lymphatic systems to distant sites. Following transport, extravasation takes place when the cells exit the vessels into the tissues of the new site. Finally, colonization occurs when the cancer cells establish a new tumor in the targeted organ or tissue.
Different types of cancers have a propensity to metastasize to particular organs, like the brain, lungs, bones, and liver.
