The overall purpose of biotherapy in cancer treatment is to enhance the immune response against cancer cells. Biotherapy, also known as immunotherapy, involves using the body’s own immune system to fight cancer. This form of treatment can take various approaches, such as monoclonal antibodies, vaccines, immune checkpoint inhibitors, and cytokines, all designed to stimulate or enhance the natural defenses of the immune system.

By targeting and bolstering the body’s immune response, biotherapy aims to identify and destroy cancer cells more effectively than conventional treatments. This method can also help the immune system remember cancer cells, potentially offering long-term protection against recurrence.

While biotherapy might also contribute to minimizing side effects or providing supportive care, its primary role is focused on activating and strengthening the immune response against tumors. This distinguishes it from other types of cancer treatments, which may directly destroy tumor cells or provide nutritional support.
