This review in Circulation compliments another review on this topic that I linked recently and makes the following additional points of interest:
Tissue factor expression and activation of the coagulation system by tumor cells facilitate tumor growth and metastasis.
Pulmonary embolism incidentally discovered on cancer imaging studies is not benign as was once thought.
The other points are similar to the review linked in the previous post. The Circulation review is available as free full text.
