The immune system is the system in your body that fights off infection. Immunotherapy is a form of medical treatment that activates your immune system to help fight Cancer. There are many different types of immune cells in your body. Other cells fight different types of Cancer.
The immune system protects the body against illness and infection that bacteria, viruses, fungi, or parasites can cause. It is a collection of reactions and responses the body makes to damaged cells or diseases. It is sometimes called the immune response.
The immune system can help to fight Cancer. Some immune system cells can recognize cancer cells as abnormal and kill them. But this may not be enough to get rid of cancer altogether. Some treatments aim to use the immune system to fight Cancer.
There are two main parts of the immune system:
Cancer avoids detection by the immune system and affects how the immune system works against other illnesses. Blood and bone marrow cancers, including lymphoma and most types of leukaemia, impact the immune system because bone marrow is where immune system cells are made. Specific treatments can also have an impact on cancer patients’ immunity.
Cancer can weaken the immune system by spreading into the bone marrow. The bone marrow makes blood cells that help to fight infection. It often happens in leukaemia or lymphoma but can also occur with other cancers. Cancer can stop the bone marrow from making so many blood cells.
Specific cancer treatments can temporarily weaken the immune system. It is because they can cause a drop in the number of white blood cells made in the bone marrow. Cancer treatments that are more likely to weaken the immune system are:
