This Popular Procedure Tripled the Cancer Risk of 1.65 Million People Last Year

The evidence is really stacking up against the routine use of many commonly used medical screening methods such as mammograms and CT scans—two ionizing radiation screening methods that I’ve been warning about since the creation of this web site.
On the heels of recent reports revealing that too many diagnostic tests are being done on adults, new reports have now come out, warning that some of these tests not only can cause cancer in children, but can induce new cancers in children who are being treated for cancer.

Chest Radiation at Young Age Contribute to Later Breast Cancers

Researchers from the Memorial Sloan-Kettering Cancer Center in New York City recently presented their findings at the annual meeting of the American Society of Clinical Oncology in Chicago, stating that girls who receive radiation to the chest to treat childhood cancer have a high risk of developing breast cancer at a young age i.

Even those who received low doses of the common cancer treatment face an increased risk of breast cancer later, the scientists said, adding that the risk posed by radiation may be as great as having the BRCA1 or BRCA2 mutation—two genetic mutations associated with an increased risk of breast cancer.

The researchers analyzed data from nearly 1,300 cancer survivors in the Childhood Cancer Survivor Study. As reported by MedPage Today ii:

“With a median follow up of 26 years, 175 of the nearly 1,300 cancer survivors later developed breast cancer at a median age of 38 years. The time between the initial therapy and later breast cancer was a median of 23 years, the researchers found…

As well, they studied 4,570 first-degree female relatives of participants in the Women’s Environmental Cancer and Radiation Epidemiology study to estimate the incidence associated with carrying two mutations, BRCA1 and BRCA2, that increase the risk of breast cancer.

Overall, Moskowitz said the cumulative incidence of breast cancer at age 50 was 24 percent, compared with the 4 percent background rate among all women reported by the Surveillance and Epidemiology End Results (SEER) database.

For women exposed to the high levels of mantle radiation formerly used to treat Hodgkin lymphoma (20 Gy or more), the cumulative incidence at age 50 was higher at 31 percent, Moskowitz said. That is similar to the 30 percent incidence seen in the cohort of relatives among carriers of the BRCA1 mutation, she said.

But even for women exposed to lower levels of whole-lung radiation (10 to 19 Gy), the cumulative incidence was elevated and was comparable to the 10 percent rate seen among carriers of the BRCA2 mutation in the cohort of relatives, she said.”

Sadly enough, the proposed “solution” is to begin mammogram screenings earlier on women who received radiation treatment in their youth, which further increases their risk of cancer! The nonsensical nature of this argument is truly mindboggling…

Routine Mammograms are Ineffective and Increase Your Risk of Breast Cancer

Mammograms expose your body to ionizing radiation that can be 1,000 times greater than that from a chest x-ray, which we know poses a cancer risk. According to Dr. Samuel S. Epstein, M.D., chairman of the Cancer Prevention Coalition, and Rosalie Bertell, Ph.D. of the International Physicians for Humanitarian Medicine iii:

“If a woman follows the current guidelines for premenopausal screening, over a 10 year period she would receive a total dosage of about 5 rads. This approximates the level of exposure to radiation of a Japanese woman one mile from the epicenter of atom bombs dropped on Hiroshima or Nagasaki.”

… [In] a study by Dr. Robert M. Kaplan, the chairman of the department of health services at the School of Public Health at the University of California, Los Angeles… they found 22 percent more invasive breast tumors in the group who had mammograms every two years compared to the group who had just one mammogram over a six-year period.”

Not surprisingly, as often happens when anyone dares speak out against those in power, both the American Cancer Society and NCI called Dr. Epstein’s findings “unethical and invalid.” But Dr. Epstein is by no means alone anymore. A number of studies have surfaced, especially in the past couple of years, shedding much-needed light on the ineffectiveness and dangers of mammography.
