The Swamp of Cancer

Resumen

What is metastasis? Metastasis is the process in which a tumor cell migrates through the circulatory system and settles in a new tissue or organ to form a secondary tumor. How does it take place? The main tumor grows and there's a migration of malignant cells through the blood to form the secondary tumor. Thereafter, there's an invasion of the new tissue or organ by different biological molecules which are important in physiological processes. And finally, tumor cells proliferate to develop the secondary tumor.
