Studies have shown that in patients over the age of 40, the risk of an undiagnosed cancer being found in patients with a spontaneous (or "unprovoked") DVT is at least 10%. The cancers which are most likely to cause DVTs are breast cancer, lung cancer, bowel cancer and pancreatic cancer.
Health scares can be good for the health if you can learn from them. I am addicted quite seriously to cigarettes, but I don't smoke anymore.
