Childhood Cancer – Let’s Talk About It

Posted by Dr. Alison McAllister on Friday, 30 September

Children's cancer ribbon

The month of September is known for both menopause month and children’s cancer awareness month. Many people commonly recognize the first but not the second.

I would just like to take a moment and talk about children’s cancer. This is not my typical blog about fun and the joy of science and research that I usually strive for.

Don’t worry, I'll blog about the wonders of estrogen, thyroid, or testosterone soon I’m sure. The ZRT family however, has been touched by a child of an employee with cancer – Go Regan! – and sadly 1 out of 300 children will be diagnosed with cancer (under the age of 18).

I personally have 3 friends whose children have had cancer and I’ve personally worked with families and been affected by their journeys.  Without awareness, there is no drive for funding of pediatric cancer research or pediatric cancer treatments which today is only 4% of the national research budget and almost zero of the pharmaceutical companies’ budgets.

3 Keys to Preventing Prostate Cancer

Posted by Dr. Allison Smith on Friday, 24 June

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

High Air Levels of Arsenic & Cadmium May Be Linked to a Cancer Cluster in Portland, Oregon

Many residents were surprised to learn 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.
