Final answer:
Biological therapy is an experimental cancer treatment strategy aiming to provide targeted treatment by developing substances, such as immunotherapy, monoclonal antibodies, targeted chemotherapy, and nanotechnology, to specifically attack cancer cells without damaging healthy tissue.
Step-by-step explanation:
Biological therapy, an experimental approach in cancer treatment, aims to utilize the body's own defense mechanisms to combat cancer. The goal of this therapy is to provide specific targeting to attack cancer cells directly without harming surrounding healthy tissue. The strategy involves the development of targeted pharmaceuticals. These advanced treatments are known as targeted therapies, and they are substances that interact with specific proteins associated with cancer cells, and can selectively inhibit their growth or kill them. Examples of such therapies include immunotherapy, monoclonal antibody therapy, targeted chemotherapy, and the use of nanotechnology.
Immunotherapy, in particular, is a method where the immune system is activated or supplemented to fight cancer. Monoclonal antibodies are lab-made proteins that can bind to cancer cells, helping the immune system identify and destroy them. Targeted chemotherapy refers to chemotherapy drugs that are designed to attack specific vulnerabilities in cancer cells. Lastly, nanotechnology in cancer treatment involves creating materials at the nanoscale to deliver drugs more effectively or to act in the body in ways that can treat cancer more precisely.
