Best of Breast: news for week ending 31 October 2014

New developments in Breast Cancer and Cancer from Google Alerts, for the week ending 31 October 2014.

We’re used to thinking of arsenic as a poison, so it comes as a surprise that arsenic in drinking water in a region in Chile has been linked to 50% lower deaths from breast cancer.

In case you were wondering where you can get hold of some arsenic, you don’t have to look any further than your supermarket:  according to a UK study, more than half the rice products in the EU exceed child safety limits for arsenic!

Talk about cereal killers!

1.  Arsenic in drinking water linked to fewer breast cancer deaths

http://newscenter.berkeley.edu/2014/10/28/arsenic-drinking-water-breast-cancer/

  • A new study has linked arsenic to a 50 percent drop in breast cancer deaths.
  • The study presents results of breast cancer mortality data from a region in Chile where residents were inadvertently exposed to high levels of arsenic, a naturally occurring element found in many minerals.
  • Instead of an increase in mortality, as with many other cancer sites, the study found that breast cancer deaths were cut in half during the period that coincided with high arsenic exposure.
  • The effect was more pronounced among women under age 60, with mortality in these women reduced by 70 percent.

2.  More than half of rice products including Rice Krispies and Heinz baby rice exceed new EU limits for ARSENIC

  • Experts warn some popular rice products contain high levels of arsenic
  • Channel 4’s Dispatches, Rice: How Safe is our Food? (which will be broadcast on Monday night) tested 81 different products with the Institute for Global Food Security at Queen’s University Belfast.
  • Tests found 58% exceeded new recommended arsenic limits for children
  • Scientists say high levels over time could lead to cancer or heart disease
  • People in Britain consume five times more rice today than 40 years ago
  • Organic original puffed rice cereal by Kallo Foods was found to have 323 parts of arsenic per billion (ppb) while Organic wholegrain baby rice by Organix was found to have 268 ppb  – 168 per cent above recommended levels for babies and children.
  • Rice Krispies by Kelloggs were found to have 188 ppb, far above the recommended levels for babies and children.
  • Baby organic rice cakes by Boots were found to be 162 ppb, and Organic wholegrain banana porridge by Organix at 142 ppb.

3.  Google Developing a Pill That Would Detect Cancer and Other Diseases

  • Google is attempting to develop a pill that would send microscopic particles into the bloodstream in an effort to identify cancers, imminent heart attacks, and other diseases.
  • The company is fashioning nanoparticles—particles about one billionth of a meter in width—that combine a magnetic material with antibodies or proteins that can attach to and detect other molecules inside the body.
  • The idea is that patients will swallow a pill that contains these particles, and after they enter the bloodstream—attempting to identify molecules that would indicate certain health problems—a wearable device could use their magnetic cores to gather them back together and read what they’ve found.

4.  War on cancer is stalling because pharmaceutical firms only create drugs they know will make a profit, leading scientist claims

http://www.dailymail.co.uk/health/article-2806496/War-cancer-stalling-pharmaceutical-firms-create-drugs-know-make-profit-leading-scientist-claims.html#ixzz3I2vuANxM

  • Paul Workman is chief executive of Institute of Cancer Research in London
  • Says despite huge advances in understanding cancer, drugs are still lacking
  • Claims theoretical scientists have identified 500 cancer-related proteins which could be attacked by drugs – but only 5 per cent of these treatments have so far been developed.
  • Argues finance is the problem, with companies putting profits first
  • Should be given incentives to develop treatments for rarer cancers
  • Calls for more targeted and smaller clinical trials that will reduce the initial outlay, and sharing the cost and risk of trials between universities and companies
