Cancer arises when any given body cell starts to divide in places and at times at which this is not desirable. The abnormal cell grows out of control and has a selective advantage over its neighbors, thereby forming a tumor. The aberrant growth in most tissues results in the formation of a solid tumor. However, tumors originating in blood, bone marrow and the lymphatic system, such as leukemia, multiple myeloma and lymphoma, don’t have a centralized location and are called ‘liquid’ tumors. Lymphoma arises in the lymph nodes or lymphatic vessels. They are full of lymphocytes, which normally help the body fight infections. However, lymphocytes grow out of control in lymphoma patients.
