Blood cancers develop in the bone marrow where the blood cells are produced. Leukaemia affects the white blood cells of your body called leukocytes and makes them grow uncontrollably. These cells are not useful, as they cannot fight infections. Lymphoma affects the lymphatic system of your body, which is a network for the immune cells to reach the disease spreading microbes. Swollen lymph nodes in the neck, underarms or groin are a major indicator of this cancer. Myeloma affects the plasma cells of your body which make the antibodies that fight infections and diseases. Without these cells, the immune system is weakened and the body is susceptible to further infections.
Although, there are no prevention methods that can completely eliminate the risk of blood cancers, maintaining a balanced diet and scheduling time for exercise. High-risk individuals should get regular medical check-ups to identifying the diseases at an early stage when fighting it is easier. As prevention starts with small steps, take precautions to change unhealthy habits and encourage your family to do the same.
