New therapeutic approaches have been developed with the aim to control tumor progression through the targeting of different components of the tumor microenvironment. This reprint will be useful for anyone who wants to learn about cancer: professors and students at universities, scientists at research institutes, biotechnology, and pharmaceutical labs, and lawyers trying to understand the patent literature.
