Biological Therapy



This therapy, also known as biotherapy, biological response modifier therapy or immunotherapy is one of the newer additions to the weaponry against cancer.

Biological therapy either augments or increases the body's ability to fight cancer, or decreases the side effects caused by toxic chemotherapy drugs.

THE WAYS IN WHICH BIOLOGICAL THERAPY ACTS:

  • Intereferes with cancer cell growth.
  • By their indirect action, these medications increase the ability of the body's cells, particularly the immune cells,which are actively involved in fighting diseases like infections and cancers.
  • These drugs help repair normal cells damaged by anti cancer chemotherapy drugs.

Biological therapy employs biological response modifiers and the common ones used are interferons, interleukins, or tumor necrosis factor.

Biologic therapy may be combined with chemotherapy or radiation therapy.

What are the side effects of biological therapy?
The side effects commonly encountered with this therapy are as follows:

  • Low grade fever.
  • Rashes and bruises.
  • Nausea and vomiting (usually mild).

All these problems disappear on cessation of therapy.
