How cancer spreads through the body
In order for a tumor to spread to distant sites, cancer cells must detach from the original tumor, pass into the circulation, enter into distant tissues, survive and grow in their new microenvironment.
In each of these steps, the cancer cells face new challenges, which they need to cope with by acquiring new properties. The most difficult barriers to metastasis are the escape from a primary tumor and the colonization in a foreign tissue. Traveling through the circulation is relatively easy in comparison.
