Immunotherapy is a method of treating cancer by stimulating the body's immune system so that it can identify and eliminate cancer cells. It can be used on its own or in tandem with other cancer therapies like chemotherapy and radiation.
The immune system functions as a network of cells, tissues, and organs to defend the body from pathogens. It does this by seeking out and eliminating disease-causing microorganisms such as bacteria, viruses, fungus, and more. There are two types of immune systems: innate and adaptive. You're born with the ability to fend off infections thanks to your innate immunity. When immune cells detect an intruder, they send out a signal to other cells in the body to begin eliminating the threat. Both phagocytes (which ingest and digest foreign bodies) and lymphocytes are examples of white blood cells. (which attach to invaders and attack). They are produced in the bone marrow and kept in various organs and tissues, including as the thymus and the tonsils and adenoids. Immunotherapy is a rapidly developing field in cancer care; it stimulates the immune system to once again attack malignant cells. Melanoma, ovarian and breast cancer, lung cancer, and colon cancer are only some of the malignancies that it is used to treat. Immunotherapy stimulates the immune system to fight cancer by using the body's own defense mechanisms, such as white blood cells called T-cells. Some patients have shown remarkable and long-lasting improvements after this awakening. Adoptive cell transfer is another type of immunotherapy that is used to increase the number of vital immune cells that are actively preventing tumor progression. The patient's blood cells are drawn off, modified in a laboratory, then reintroduced to the patient through an intravenous drip. Acute lymphoblastic leukemia in children and some forms of B-cell lymphoma in adults that haven't responded to conventional treatments are two examples of cancers for which this method has been approved. Immunotherapy is effective because it guides the body's immune system to locate and eliminate cancer cells. However, it comes with potential negative impacts on your health. Some of these negative reactions are temporary and will disappear on their own. On the other hand, some may be more severe or persistent. Tell your doctor right away if any of your adverse effects become severe or persistent. This information will be useful for both continuing treatment and stopping it abruptly if necessary. The skin, lungs, joints, heart, and possibly even other organs can be affected. They may cause discomfort or make it difficult to carry out daily tasks. Your doctor may prescribe medicine to suppress your immune system or temporarily suspend immunotherapy if the adverse effects are severe enough. If this doesn't work, your doctor may increase your immunotherapy dosage or try a different medication. Immunotherapy is a method of treating cancer that makes use of the body's own immune system to eliminate malignancies. Some people with cancers that haven't responded to standard therapies like chemotherapy or radiation may benefit from this procedure. Additionally, it extends the time period during which some people are cancer-free. If cancer does return, a boosted immune system will be better able to detect and destroy the offending cells. Clinical trials are being conducted on a wide variety of immunotherapies to determine which ones are most effective against specific tumors. The application of immunotherapy in the treatment of genetic disorders, autoimmune illness, and inflammation is also being explored. There are potential negative consequences of immunotherapy. These may occur before, during, or after therapy and range from minor to severe. Flu-like symptoms, tiredness, and skin responses like a rash are all possible side effects. Steroids or other medications may alleviate these unintended effects.
