On Prostate Cancer Prevention – Identifying Areas of Susceptibility

Posted by Dr. Allison Smith on Friday, 24 June

In our current medical paradigm, screening for cancer is considered a preventive measure by virtue of providing an earlier diagnosis. Getting an early jump on a disease process like cancer makes treatment exponentially easier and outcomes generally better. Under the current guidelines, that early jump on prostate cancer starts at age 55 for men at low to moderate risk and 40-45 for men at high risk. It takes years for cancer to grow to a detectable point after the tumor's initial induction from a normal cell to a cancerous one. There's been a lot of research done to determine what those inducers are and how they work. Three of these inducers are simple to test for and completely modifiable with treatment and/or avoidance:

  • Bisphenol A
  • Arsenic
  • Catechol estrogens

Element Testing – Why Sample Type Matters!

Posted by Ted Zava on Tuesday, 03 May

Urine, serum, plasma, whole blood, red blood cells, feces, hair, fingernails … the list goes on. How do you decide what biological sample(s) to use for element analysis? Can results be compared to scientific literature or do they have clinical significance? Is it possible for values to be elevated or low in one sample type and normal in another? Do test results indicate recent intake, body burden, acute toxicity, chronic toxicity, deficiency, or homeostatic regulation? These are just some of the questions facing a testing laboratory when they want to develop and validate essential and toxic element profiles that will provide clinically meaningful results.

Many residents were surprised to learn today that high levels of arsenic and cadmium are being detected at an air monitoring station in Southeast Portland, Oregon according to the state Department of Environmental Quality (DEQ)

Watch the News: Dr. Zava comments on toxin exposure in SE Portland

The state began monitoring air quality after moss samples taken from the area last October were found to be high in arsenic and cadmium. The results, which were only made public in the past few days, show cadmium at 49 times the acceptable level and arsenic at 159 times the acceptable level for air.

Of key concern is that the testing location is in an area populated with businesses, schools, and parks. It is not clear yet how long exposure has occurred or whether it is caused by a nearby glass blowing facility. As of this week, the glass blowing facility decided to cease use of arsenic and cadmium.

Colorado Mine Spill Makes High Levels of Toxic Metals a Threat to Humans & Wildlife

Posted by Ted Zava on Monday, 17 August

colorado.mine.spill.blog_1On August 5, 2015 the Environmental Protection Agency (EPA) accidentally breached a tunnel holding liquid waste as part of the cleanup of the Gold King Mine in Colorado.

This breach resulted in the release of 3 million gallons of toxic waste into Colorado’s Animas River. The waste stained the river yellow and continued to travel downstream into the San Juan River. The Animas and San Juan Rivers are a source of drinking and irrigation water, are heavily used for recreation, and are home to a wide variety of wildlife.
