Cancer and its treatment can weaken your body’s immune system by affecting the blood cells that protect us against disease and germs.
The immune system is the body's network of cells and organs that is specially developed for fighting off infections. Weaknesses in the immune system can be either congenital, meaning someone is born with them, or acquired, caused by outside factors. Disorders of the Immune System. Your immune system is your body's defense against infections and other harmful invaders. Without it, illnesses from bacteria or viruses, for example, would be constant. Your immune system is made up of special cells, tissues, and organs that work together to protect you. What the immune system does. The immune system protects the body against illness and infection caused by bacteria, viruses, fungi or parasites. It is really a collection of reactions and responses that the body makes to damaged cells or infection. So it is sometimes called the immune response. The lymph, or lymphatic, system is a major part of the immune system. It's a network of lymph nodes and vessels. Lymphatic vessels are thin tubes that branch, like blood vessels, throughout the body. They carry a clear fluid called lymph. Lymph contains tissue fluid, waste products, and immune system cells. The immune system protects the body against illness and infection caused by bacteria, viruses, fungi or parasites. It is really a collection of reactions and responses that the body makes to damaged cells or infection. 2. Lacking fever – a sign low immunity. A good immune system has power, power to kill viruses, bacteria, and cancer cells. That power comes from heat, called fever. A strong immune system should be able to raise core temperature high enough to create unfavorable environment for the invaders. Cancer and its treatment can weaken your body’s immune system by affecting the blood cells that protect us against disease and germs. As a result, your body can’t fight infection, foreign substances, and disease as well as a healthy person’s body can. Immune system disorders cause abnormally low activity or over activity of the immune system. In cases of immune system over activity, the body attacks and damages its own tissues (autoimmune diseases). Immune deficiency diseases decrease the body's ability to fight invaders, causing vulnerability to infections.
