A frequently broken nose, that is, frequent nosebleeds, does not necessarily mean leukemia. This situation is generally caused by two main reasons: 1. local factors. Local factors are generally dry nasal mucosa resulting in nasal mucosal erosion, after the mucosal erosion leads to the exposure of some blood vessels under the mucosa and easy bleeding. This kind of bleeding is mainly arterial bleeding, and the amount of bleeding is usually more each time. This situation generally goes to the ENT clinic, let the doctor to do an examination, you can see some bleeding points, generally can be filled with treatment, endoscopic electrocoagulation hemostasis treatment. 2, systemic factors. Systemic factors include the following: firstly, patients with hypertension and atherosclerosis have poorer compliance of the arterial wall and are prone to rupture and bleeding. Secondly, patients with coagulation dysfunction, for example, some patients have thrombocytopenia coagulation dysfunction. In this case, blood tests can be routinely drawn to check routine blood and coagulation function. If there is a problem, it is recommended to do a bone marrow aspiration, through which the possibility of leukemia can be ruled out.
