Cancer
Cancer is a disease in which cells in the body grow abnormally. Cancer cells can invade and destroy nearby tissues. Cancer cells can also spread to other parts of the body. There are many types of cancer, each with its causes, symptoms, and treatments.
Cancer can cause low lymphocytes because it destroys normal cells by attacking them or making them sick, so they die before their time. This happens when cancerous white blood cells break through or damage the skin or mucous membranes (the moist tissues lining the mouth and nose).
