Biological or biologic therapy is a treatment that aims to boost or restore the body's immune (natural defense) system's ability to combat infection and disease. Biological therapy, also known as biotherapy or immunotherapy, is a treatment option for a variety of cancers and other diseases. Biological therapy frequently includes the use of biological response modifiers (BRMs). These compounds are routinely produced in small amounts by the body in response to infection and diseases. BRMs can be produced in huge quantities using modern laboratory techniques.
Radiopharmaceuticals are biologically active compounds that are labelled with radionuclides to provide a viable source of ionizing radiation for diagnostic and therapeutic purposes. Radiopharmaceuticals are drugs that are used to diagnose and treat medical conditions. They can be administered to the patient in a variety of methods. They can be given by mouth, by injection, or by placing them in the eye or the bladder, for example.
