Cancer is the highest single risk factor for thrombosis.

It is estimated that up to 20% of patients with cancer experience venous thrombosis (VTE).

There is a fivefold higher annual incidence of thrombosis among cancer patients, with about 1 in 1,000 in the general population and 1 in 200 in cancer patients.
