In this module, we'll focus on uncontrolled cell division, which is a defining property of cancer, as well as mutation and neoangiogenesis and their roles in tumor formation. We'll also take a look at a primary tumor microenvironment and its component cell types.

During this module, we'll turn our attention to the next steps after the initial primary tumor formation, epithelial to mesenchymal transition of cancer cells, and local tumor invasion and intravasation into blood or lymph vessels.

We'll now take a close look at cancer survival within the circulation, the role of the circulatory system in metastasis, the genetic determinants of metastatic potential, signalling mechanisms, chemokines, the dock and lock hypothesis, and extravasation.

In this module, we'll focus on dormancy and secondary tumor growth and how they contribute to the lethality of cancer.

In the previous modules, we've looked closely at the sequential steps of metastasis and some of the biology of how metastasis occurs. Now, we'll turn our attention to morbidity and mortality, or in other words, how cancer hurts and kills people.
