Leukemia probably lives about two months to a year if left untreated. If it is acute leukemia, you will probably live about two to three months.
How long a person with leukemia can live depends largely on the specific condition of the leukemia. If it is acute leukemia, the disease progresses faster and you can live up to two to three months without treatment, but chronic leukemia can live about six months to a year, or even longer, because it is more stable.
How long you can live without treatment is related to the degree of malignancy of the leukemia, but it also has a lot to do with your health. If you have a strong immune system, you can live a few more years, but if you have a poor health and a low immune system, then the leukemia can spread very quickly.
Leukemia is caused by the presence and accumulation of large numbers of naive and abnormal white blood cells in the hematopoietic system and bone marrow. Leukemia is the same as tumorigenic hyperplasia, there is no way to control it and it is very easy to cause the bone marrow hematopoietic function to be affected, which can make the patient anemic. The result is that the patient will become anemic. The cure for leukemia requires a bone marrow transplant.
