Early radiation exposure raises breast cancer risk

Cancer News: Early radiation exposure raises breast cancer risk

Exposure to radiotherapy or radiation-based diagnostics like computed tomography (CT scans) in early childhood increases breast cancer risk in adulthood, a new study in the Jan 2010 issue of Cancer Epidemiology, Biomarkers & Prevention.

The study involved women exposed to thymic irradiation during infancy from 1926 to 1957. Breast cancer was identified in 96 treated in an average dose of 0.71 Gy and 57 untreated women during 159,459 person-year follow-up.

Adams MJ and colleagues from University of Rochester School of Medicine and Dentistry found women who were treated by radiation were 200 percent more likely to develop breast cancer than those who did not receive radiation.

Higher doses of radiation were linked to high risk of breast cancer.

The researchers concluded that “at radiation doses between those received by the breast from chest CT and cancer therapy during early childhood, breast cancer incidence rates remain elevated >50 years after exposure.”

They wrote “This implies that increased breast cancer risk will remain a lifelong concern in females treated during childhood with currently reduced radiotherapy doses and for infants receiving multiple chest CTs.”

John Gofman, Ph.D. M.D. a distinguished nuclear physician, had reported much earlier that 75 percent of women with breast cancer were exposed to either diagnostic imaging, test or radiation therapy.

Ionizing radiations including x-ray used in medical diagnostics, mammogram screenings, air port whole body scanning, and cancer treatment are recognized by the U.S. National Toxicology Program as cancer-causing agents.

Breast cancer is diagnosed in more than 170,000 women each year in the United States and the disease kills about 50,000 annually in the country.

Breast cancer symptoms include a lump or thickening that feels different from the surrounding tissue, bloody discharge from the nipple, change in size and or shape of a breast, formation of dimples on the breast skin, inverted nipple, peeling or flaking of the nipple skin and redness on the breast skin like the skin of an orange, according to mayoclinic.com

Breast cancer treatments include surgery, radiation therapy, chemotherapy, hormone therapy, and targeted therapy.

BBC promotes conventional x-ray technology to be used on only ‘suspicious’ travelers at Newcastle Airport.

These X-ray scanners send a high-energy beam of electromagnetic waves that pass through the subject to digitally create the x-ray image of the persons’ insides. These machines are similar to the Backscatter X-ray scanners (the scanners that look like 2-boxes you step in-between) but rely on low-energy x-ray waves that are only strong enough to pass through clothing producing the ‘blue alien‘ image of the persons figure.

X-rays that penetrate the human body are extremely dangerous and can even be deadly, people who use them significantly increase the risks of internal cancer and tumor growth. Women are especially susceptible to these deep penetrating rays as breast tissue has is very vulnerable to cancer, children and the unborn are the most at-risk.

The Backscatter and millimeter-wave are far less damaging than conventional x-ray, but Backscatter machines still rely on ionizing x-ray and millimeter-wave scanners rely on terahertz waves still be absorbed by the very surface of the skin, destroying, mutating DNA and skin cells which could lead to cancer.

Here is CNN’s Sanjay Gupta failing to mention that terahertz waves from millimeter-wave machines have been tested to “unzip double-stranded DNA, creating bubbles in the double strand that could significantly interfere with processes such as gene expression and DNA replication (that can potentially cause cancer)”.

He also fails to mention that radiation damage is cumulative and with each dose builds upon cellular mutation caused by the last –in other words– these machines can effect previously damaged cells to trigger the spread of cancer.
