If you have leukemia, you will continue to have nosebleeds, most of which are due to a decrease in blood clotting factors, and if there is a breakdown of the mucous membrane in the nasal cavity, there will be a continuous flow of blood from the mucous membrane. The bleeding often stops only when the bleeding triggers a drop in blood pressure.
Most nasal bleeding from leukemia is often accompanied by bleeding from other parts of the body, such as subcutaneous bleeding and intracranial bleeding; because nasal bleeding can flow blood outside the nasal cavity, it does not cause serious damage to the body in the short term and can be controlled gradually through rehydration or blood transfusion. The first time I saw this, I was able to get to the top of the list, and I was able to get to the bottom of the list.
