Copper Cancer: Copper may cause cancer
and tumor chemotherapy resistance
Researchers found copper blood levels were lower in patients
without cancer. They state copper is involved in the development of cancer. Analysis of patients with breast
cancer, colon cancer and lung cancer showed that serum copper was higher in patients not responding to
chemotherapy compared to patients whose tumors responded to chemotherapy treatment. Additional research has identified the cellular ATP7A and ATP7B related drug
transport systems as the source of copper induced cancer tumor resistance to chemotherapy.
An extreme deficiency or excess
of any nutrient in our body, including water will cause a health problem. The essential nutrient copper is not
any different. It is required for many processes in the body. A deficiency is life threatening.
Copper excess increases the risk of cancer, atherosclerosis, oxidative damage, Alzheimer’s, Parkinson’s and a host of other diseases.
Sources of high amounts of
copper include some dietary supplements, drinking water, bath water and shower water. A person with cancer
should test their urine and blood for copper.
A Heavy Metal Screening Test is available for home urine testing. It’s
difficult to get a doctor to order and find a lab that can do a copper, ionized (free) copper and copper bound
to ceruloplasmin. The ionized copper is the most difficult test to
find.
Copper chelation reduces the
body’s production of tumor blood vessel growth factors (angiogenesis) and reduces tumor growth and small blood vessel density in animal studies.
Human studies of oral chelation drugs are currently underway.
Chelation should be done with
caution under guidance of a health care professional. I know of one person that went into atrial fibrillation
due to magnesium deficiency caused by unsupervised daily, oral, non-prescriptioni chelation. Chelation
products will bind and remove toxic metals and essential minerals from your body, food and supplements.
You should monitor copper and mineral levels and adjust dosages as indicated.
