What is Venous Thromboembolism? | CDC

Cancer and Deep Vein Thrombosis Cancer and some types of cancer treatments can increase the risk of deep vein thrombosis (DVT), a blood clot that occurs in a deep vein, usually in the lower leg, thigh, pelvis, or arm. When DVT occurs, it often includes swelling, pain, tenderness, and redness of the skin, but for some people, there may not be any symptoms. DVT can cause serious complications if a part of the blood clot breaks off and travels through the bloodstream to the lungs, causing a blockage called pulmonary embolism (PE). Knowing your risk for DVT is important because complications can include serious illness, disability, and in some cases, death. DVT can be prevented and treated if discovered early.
