Maintains Bones, Joints, Neurons and May Reduce Prostate Cancer Risk
by Stephen B. Strum, M.D., FACP
Medical Oncologist Specializing in Prostate Cancer


Boron, the fifth element in the periodic table of elements, has a number of important functions that are worthy of intense clinical attention. Boron is an integrative element supporting the functions of calcium, magnesium, and vitamin D. Boron enhances bone and joint integrity and brain function. The results of a recent study indicate that boron is the most significant element in the prevention of prostate cancer. This finding complements an exciting basic research study showing that boron, an inhibitor of serine proteases such as PSA, lowered PSA and prostate cancer volume significantly. This simple and relatively inexpensive element deserves a major focus of funding in the world of research and clinical medicine.

Stephen B. Strum, M.D. has been a board-certified medical oncologist since 1975. In 2000 he became the first medical director of the Prostate Cancer Research Institute in Los Angeles. Dr. Strum has published widely about prostate cancer as well as other areas to optimize outcomes for those with cancer.


ACRONYM: A word formed from the initial letters of a name, such as BNCT for Boron Neutron Capture Therapy.

ADJUNCT: Something added to another for embellishment or completion.

ADJUVANT: An additional therapy that is added to a primary treatment to increase or aid its effect. Adjuvant therapy is usually given once the primary therapy is completed, e.g., radiation therapy after primary surgery. Neoadjuvant therapy indicates that the additive therapy is given prior to the so-called primary therapy. For example, neoadjuvant androgen deprivation therapy is often used prior to radiation therapy.

COCKEREL: A young rooster.

KILOGRAM (kg): A unit of mass equaling one thousand grams or 2.2 pounds.

MICROGRAM (mcg or mg): A unit of mass equaling one millionth of a gram.

MICRON: A unit of length equal to one millionth of a meter or approximately 1/25,000 of an inch.

MILLIGRAM (mg): A unit of mass equaling one thousandth of a gram.

NOAEL: No-Observed-Adverse-Effect Level. This is an acronym used to categorize toxicity of various drugs, vitamins, and supplements.

PROTEOLYTIC: Having the ability to break down proteins by enzyme actions.

QUARTILE: The value of the boundary at the 25th, 50th, or 75th percentiles of a frequency distribution; this is divided into four parts, each containing a quarter of the population. In a class of 100 students, those 25 students with the highest grades are in the upper quartile of the class, while the 25 with the lowest grades are in the lowest quartile.
