Introduction
In general, patients with lymphoma may exhibit different blood test results at various stages and during different treatments. Therefore, whether blood test results are normal needs to be determined based on specific circumstances. Regular blood tests should be performed routinely, especially during treatment when the testing frequency should be increased as directed by a physician, so that any abnormalities can be detected promptly. When white blood cell counts are low, patients should avoid crowded places.
In general, blood test results for patients with lymphoma may vary depending on the disease stage and type of treatment received. Therefore, whether a complete blood count (CBC) is normal must be determined based on individual circumstances. The detailed analysis is as follows:
If a lymphoma patient is in the early stage of the disease and has not yet received treatment, or is undergoing treatments such as targeted therapy that have minimal impact on bone marrow, the CBC results may remain normal. In the early phase, when the disease has not involved the bone marrow and hematopoietic function remains largely intact, indicators such as white blood cells, red blood cells, and platelets can stay within normal ranges. Additionally, certain targeted drugs specifically attack lymphoma cells while causing minimal damage to healthy blood-forming cells, which may also result in no significant abnormalities in CBC parameters.
However, if the patient is in an advanced stage of lymphoma or has undergone treatments like chemotherapy or radiotherapy, blood test results are typically abnormal. In advanced stages, lymphoma cells invading the bone marrow can suppress hematopoiesis, leading to reduced white blood cell and platelet counts. Chemotherapy and radiation therapy, while effective at killing tumor cells, also damage normal hematopoietic cells, resulting in abnormalities such as decreased levels of white blood cells, platelets, and red blood cells.
Routine monitoring of blood counts is essential, especially during treatment, when testing frequency should be increased according to medical advice to promptly detect any abnormalities. When white blood cell counts are low, patients should avoid crowded places and maintain good personal hygiene to prevent infections. If platelet counts are low, strenuous activities and physical trauma should be avoided to prevent bleeding. Symptoms such as dizziness, fatigue, fever, or gum bleeding require immediate medical attention. A diet rich in protein and vitamins is recommended to support recovery and enhance blood cell production.
