One more reason to fear our environment and go for the big guns to treat cancers. And avoid BPA as best we can.

What is BPA? (From the article.)
"BPA is one of the most common chemicals to which we are exposed in everyday life. It is the building block of polycarbonate plastic and is also used in the manufacture of epoxy resins. According to Environment Canada (the Canadian equivalent of the EPA), more than 4 billion kilograms (4.4 million tons) of the chemical were produced globally in 2006, and more than 1 billion kilograms (1.1 million tons) were produced in the United States in 2007 (CEPA, 2009)."

I found the below statement absolutely mind-boggling and is also relevent to the "can positive thinking help cure our cancer" thread.

"Studies using cultures of human breast cancer cells demonstrate that BPA acts through the same response pathways as the natural estrogen estradiol (Rivas, 2002; Welshons, 2006). BPA can interact weakly with the intracellular estrogen receptor (ER), and it can also alter breast cell responsiveness and induce cell proliferation in vitro and in vivo. It affects cellular functions through interactions with the membrane estrogen receptor (Watson, 2005; Wozniak, 2005). Along with its many other effects on cell growth and proliferation, BPA has been shown to mimic estradiol in causing direct damage to the DNA of cultured human breast cancer cells (Iso, 2006).
In the presence of BPA, cells from the non-cancerous breast of women diagnosed with breast cancer had a gene-response profile associated with the development of highly aggressive tumors (Dairkee, 2008). Two new studies indicate that BPA reduces the efficacy of common chemotherapy agents (cisplatin, doxirubicin and vinblastin) in their actions against proliferating breast cancer cells when tested in cell systems (LaPensee, 2009; 2010). Thus, not only does early exposure to BPA lead to an increased risk for development of breast tumors, but exposure to BPA during chemotherapy treatment for breast cancer may make the treatment less effective."

MY STORY SO FAR ~~~~ Found suspicious lump 9/2000 Lumpectomy, then node dissection and port placement Stage IIB, 8 pos nodes of 18, Grade 3, ER & PR - Adriamycin 12 weekly, taxotere 4 rounds 36 rads - very little burning 3 mos after rads liver full of tumors, Stage IV Jan 2002, one spot on sternum Weekly Taxol, Navelbine, Herceptin for 27 rounds to NED! 2003 & 2004 no active disease - 3 weekly Herceptin + Zometa Jan 2005 two mets to brain - Gamma Knife on Jan 18 All clear until treated cerebellum spot showing activity on Jan 2006 brain MRI & brain PET Brain surgery on Feb 9, 2006 - no cancer, 100% radiation necrosis - tumor was still dying Continue as NED while on Herceptin & quarterly Zometa Fall-2006 - off Zometa - watching one small brain spot (scar?) 2007 - spot/scar in brain stable - finished anticoagulation therapy for clot along my port-a-catheter - 3 angioplasties to unblock vena cava 2008 - Brain and body still NED! Port removed and scans in Dec. Dec 2008 - stop Herceptin - Vaccine Trial at U of W begun in Oct. of 2011 STILL NED everywhere in Feb 2014 - on wing & prayer 7/14 - Started twice yearly Zometa for my bones Jan. 2015 checkup still shows NED 2015 Neuropathy in feet - otherwise all OK - still NED. Same news for 2016 and all of 2017. Nov of 2017 - had small skin cancer removed from my face. Will have Zometa end of Jan. 2018.
