<unk>  or thromboprophylaxis is medical treatment to prevent the development of<unk>  (blood clots inside blood vessels) in those considered at risk for developing<unk> . Some people are at a higher risk for the formation of blood clots than others.<unk>  measures or interventions are usually begun after surgery as people are at higher risk due to immobility. People undergoing surgery with cancer are at an increased risk of blood clots. Blood thinners are used to prevent clots, these blood thinners have different effectiveness and safety profiles. Research found 20 studies that included 9771 people with cancer. The evidence did not identify any difference between the effects of different blood thinners on death, developing a clot, or bleeding. Less bruising following surgery occurred with some while others may have reduced the risk of getting a blood clot but the reliability of evidence varied from low to moderate. A 2021 Cochrane review found that low molecular weight heparin (LMWH) was superior to unfractionated heparin in the initial treatment of venous thromboembolism for people with cancer. There are medication-based interventions and non-medication-based interventions. The risk of developing blood clots can be modified by life style modifications, the discontinuation of oral contraceptives, and weight loss. In those at high risk both interventions are often used. The treatments to prevent the formation of blood clots is balanced against the risk of bleeding. One of the goals of blood clot<unk>  is to limit venous stasis as this is a significant risk factor for forming blood clots in the deep veins of the legs. Venous stasis can occur during the long periods of not moving.<unk>  is also recommended during air travel.<unk>  prophylaxis is effective in<unk> g the formation of blood clots, their lodging in the veins, and their developing into thromboemboli that can travel through the circulatory system to cause blockage and subsequent tissue death in other organs. Clarence Crafoord is credited with the first use of<unk>  prophylaxis in the 1930s.
