Immunotherapy is a treatment that uses certain parts of a person’s immune system to fight diseases such as cancer. This can be done in a couple of ways:
Some types of immunotherapy are also sometimes called biologic therapy or biotherapy.
In the last few decades immunotherapy has become an important part of treating some types of cancer. Newer types of immune treatments are now being studied, and they’ll impact how we treat cancer in the future.
Immunotherapy works better for some types of cancer than for others. It’s used by itself for some of these cancers, but for others, it seems to work better when used with other types of treatment.
Your immune system is a collection of organs, special cells, and substances that help protect you from infections and some other diseases. Immune cells and the substances they make travel through your body to protect it from germs that cause infections. They also help protect you from cancer in some ways.
The immune system keeps track of all of the substances normally found in the body. Any new substance that the immune system doesn’t recognize raises an alarm, causing the immune system to attack it. For example, germs contain substances such as certain proteins that are not normally found in the human body. The immune system sees these as “foreign” and attacks them. The immune response can destroy anything containing the foreign substance, such as germs or cancer cells.
The immune system has a tougher time targeting cancer cells, though. This is because cancer starts when cells become altered and start to grow out of control. The immune system doesn’t always recognize cancer cells as foreign.
Clearly, there are limits on the immune system’s ability to fight cancer on its own, because many people with healthy immune systems still develop cancer. Sometimes the immune system doesn’t see the cancer cells as foreign because the cells aren’t different enough from normal cells. Sometimes the immune system recognizes the cancer cells, but the response might not be strong enough to destroy cancer. Cancer cells themselves can also give off substances that keep the immune system in check.
To overcome this, researchers have found ways to help the immune system recognize cancer cells and strengthen its response so that it will destroy them.
The main types of immunotherapy now being used to treat cancer include:
At KCC we have specially trained doctors in immunotherapy and we are one of the hospitals which started this type of treatment successfully in Kerela. At present this treatment is mainly used for lung cancer, renal cell carcinoma, melanoma and lymphoma.
