About Us

Freeport, Grand Bahama, Bahamas

The objective here at the IAT Centre is to restore function to your immune system and to identify any loss of function you may have in any system, and direct you to restorative and regenerative therapies for that system. You are only as healthy as your least functional system in your body.

A declining immune function is part of the aging process, and many of us are experiance symptoms of such a change. For some people, this loss of immune function comes earlier and may manifests as a chronic infection or as cancer due to a failure by your immune response to identify and contain cancer cells.

At the Immune Augmentative Therapy Centre we have been working to find the best therapies available to restore your immune function since 1977. Lawrence Burton Ph.D. opened the IAT Clinic in Freeport after his many years of successful research therapy in the USA on the immune systems of hundreds of terminally ill cancer clients. With the establishment of the IAT in the Bahamas, Dr. Burton was able to further refine his treatments with the use of isolates serum cytokines and immune directive proteins from healthy people to help improve the immune system in people with cancer.

Each cancer treatment plan is customized to the person with cancer. In addition to immune therapy, such as cancer vaccine, we provide angiogenesis inhibition (blocking new blood vessels that feed tumor), apoptosis inducing agents (to help tumor cells to commit suicide), and cytotoxic agents that kill tumor cells while not destroying normal cells.

    Joan was diagnosed in April, 1979, after her salivary gland was excised. She came to the IAT Clinic following extensive radiation. Her prognosis was "terminal" by a well known head & neck surgeon in NYC. He gave her three options: 30% chance of survival with radical surgery of the face, jaw & tongue. Less percent with less radical surgery, or extension of life for a short period  of time with radiation, only. She chose radiation, keeping her face in tact & began the IAT treatment in September of 1979...Now, 32 years later, she continues to be cancer free , thanks to the Immuno Augmentative Therapy. - J.W.

    “In March 2000 I was diagnosis with mesothelioma and given a few months to live. A week later my husband brought me from England, traveling in a wheelchair, to the Cancer Clinic in the Bahamas. Within a few weeks of the treatment I was much stronger, swimming in the sea and going for long walks on the beach. I have remained completely fit and healthy since then. My last 3 annual CT scans showed no growth of the cancer-HOORAY!” - S.E.
