It is a collection of reactions and responses that the body makes to damaged cells or infection.

So it is sometimes called the immune response. Cancer can weaken the immune system by spreading into the bone marrow. The bone marrow makes blood cells that help to fight infection. This happens most often in leukaemia or lymphoma, but it can happen with other cancers too.

The cancer can stop the bone marrow from making so many blood cells. Certain cancer treatments can temporarily weaken the immune system.

This 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:. You can find information about the different types of cancer treatments.

Some cells of the immune system can recognise cancer cells as abnormal and kill them. But this may not be enough to get rid of a cancer altogether. This is also called innate immunity. These mechanisms are always ready and prepared to defend the body from infection.

They can act immediately or very quickly. This in built protection comes from:. Certain cancer treatments can also overcome these protection mechanisms.

Chemotherapy can temporarily reduce the number of neutrophils in the body, making it harder for you to fight infections. Radiotherapy to the lung can damage the hairs and mucus producing cells that help to remove bacteria.

Neutrophils are a type of white blood cell that are very important for fighting infection. They can:. Chemotherapy, targeted cancer drugs and some radiotherapy treatments can lower the number of neutrophils in the blood.

Although antibodies can recognize an antigen and lock onto it, they can't destroy it without help. That's the job of the T cells. They destroy antigens tagged by antibodies or cells that are infected or somehow changed.

Some T cells are actually called "killer cells. These specialized cells and parts of the immune system offer the body protection against disease.

This protection is called immunity. The immune system takes a while to develop and needs help from vaccines. By getting all your child's recommended vaccines on time, you can help keep your child as healthy as possible.
