Yes, it is possible to have leukemia for years without knowing. Leukemia is a type of cancer that affects the blood cells and bone marrow, and it can sometimes take years for the symptoms to become severe enough to be noticed. During the early stages of the disease, a person may experience only minor symptoms such as fatigue, fever, and anemia, which can often be attributed to other illnesses or conditions. As the disease progresses, more severe symptoms can occur such as persistent bruising or bleeding, frequent infections, bone or joint pain, and swollen lymph nodes. In addition, some types of leukemia can cause an enlarged spleen, weight loss, and pale skin.
If a person suspects they may have leukemia, they should see a doctor immediately. The doctor can perform a physical exam, blood tests, and a bone marrow biopsy, which can help diagnose the condition and determine the type and stage of the disease. Treatment options for leukemia vary depending on the type and stage, but they can include chemotherapy, radiation therapy, stem cell transplants, and other medications.
Although it is possible to have leukemia for years without knowing, it is important to be aware of the symptoms and to see a doctor if any are present. Early diagnosis and treatment can help to improve the chances of a successful outcome.
