Understanding Immunotherapy
Immunotherapy is a new way to fight cancer that uses the body’s own defense. It helps the body see and fight cancer cells better. This method changes how we treat cancer, using the patient’s immune system to help.
What is Immunotherapy?
Immunotherapy is a targeted therapy that uses the immune system to fight cancer. It boosts the body’s immune defenses and targets specific cancer cells. This therapy teaches the immune system to find cancer cells better, without harming healthy cells.
How Immunotherapy Works
Is Immunotherapy Effective? Immunotherapy works in several ways. It uses immune checkpoints, which are molecules that control the immune response. By blocking these checkpoints, drugs help the immune system find and attack cancer cells better.
Types of Immunotherapy Treatments
Immunotherapy uses the immune system to fight cancer. We’ll look at three main types of treatments. These include checkpoint inhibitors, cancer vaccines, and adoptive cell transfer. Each type works differently and targets specific cancers.
Checkpoint Inhibitors
Checkpoint inhibitors are special antibodies. They stop proteins that block T-cells from fighting cancer cells. By stopping these proteins, the immune system can attack tumors better. Treatments like pembrolizumab (Keytruda) and nivolumab (Opdivo) help with cancers like melanoma and lung cancer.
Is Immunotherapy Effective? Clinical trials show they can make people live longer and get better results.
Cancer Vaccines
Cancer vaccines help the immune system fight cancer cells. They have antigens that make the immune system react against tumors. For example, sipuleucel-T (Provenge) helps with prostate cancer and has made people live longer.
Researchers are working on new vaccines to help more people with cancer.
Adoptive Cell Transfer
Adoptive cell transfer takes T-cells from a patient and changes them to fight cancer. CAR-T therapy is a big part of this. It’s very effective against some leukemias and lymphomas.
Is Immunotherapy Effective? This therapy changes T-cells to target cancer cells directly. It’s a big step in personalized medicine, giving treatments that fit each patient’s needs.
Benefits of Immunotherapy
Immunotherapy is a new way to fight cancer. It uses the body’s immune system to find and attack cancer cells. This method is unique and offers a new way to treat cancer.
