The role of mammography in causing cancer is not a scientific issue: it is a major issue on the functioning of scientific institutions.

1/n
There is large evidence showing that ionizing radiation creates DNA damage, the main mechanism of cancer. X-rays used in radiology are ionizing radiation.
2/n
Last year, Archie Bleyer and I published in the New England Journal of Medicine epidemiological evidence showing that a large increase in breast cancer incidence occurred following mammography screening (Corcos & Bleyer, NEJM, 2020).
3/n
Others have shown in unbiased studies that there is a perfect correlation between mammography screening and breast cancer incidence (Harding et al., JAMA Int. Med., 2015).
4/n
5 years ago, I tried to publish a manuscript showing that the excess cancers which was observed after mammography screening in the UK was not related to detection but to the previous mammograms.

5/n
This manuscript was serially rejected without valid arguments and can be seen as a preprint. biorxiv.org/content/10.110…
6/n
As this is a major medical question, one would at least expect some kind of rebuttal with some counterargument as in any scientific issue.
7/n
Instead, I was dismissed from my permanent position at the @Inserm after putting my manuscript online in BioRxiv.
8/n
Similar problems were encountered by John Gofman when he found that «low » doses of radiations were causing a lot of cancers.
ratical.org/radiation/CNR/…
9/n
Actually, most of the data from the scientific literature support Gofman’s results, but it is forbidden to reach this conclusion.
10/n
Radiological examinations continue to be a leading cause of cancer and medical authorities refuse a scientific approach to the issue.

11/n
As our data are now in the NEJM, we did not expect a cover-up with the complicity of the media.
12/n
A reminder of what is happening now with the #originofcovid.

Remember the HIV vaccine?

The trial was criticised five years ago by 22 prominent U.S. scientists who doubted it would have any effect. Washington was accused of wasting more than a $100 million (63 million pounds) by funding it.
1/
“It was a tough decision. I am glad we made it,” said Dr. Anthony Fauci, director of the U.S. National Institute of Allergy and Infectious Diseases, who defied the criticism and continued the trial.
2/
Anthony Fauci, also a backer of the test, said of the results: "I don't want to use a word like 'breakthrough,' but I don't think there's any doubt that this is a very important result,"

The Covid-19 epidemic that has claimed millions of lives began in the city of Wuhan, a modern city in China with an institute (the WIV) where bat coronaviruses were studied and housed.
2/n
The most basic way to determine if the SARS-CoV-2 that claimed so many victims came from the WIV would have been to find out what work was being done there by obtaining funding requests and lab notebooks.`

Starting biennial screening mammography at age 40 could cut cancer deaths in Black women by 57%, according to a model study of 100 million women published October 18 in the @AnnalsofIM
auntminnie.com/index.aspx?sec…
See the problems?
1/n
1. This is a model without any observational data.
2. This is ridiculous: there is less than 20 million black women in the USA.
3. According to all long term observational studies, we hardly see any benefit of mammography screening on cancer deaths in women over 50 ...
2/n
, for whom screening should be more effective.
4. Most countries do not recommend screening before 50.
5. The authors do not take into account the fact that mammography screening has actually caused a breast cancer epidemic (Corcos & Bleyer, NEJM)

The chance that a woman will die from breast cancer in developed countries is 1 in 40 (remember that 1 out of 8 women will have breast cancer). Therefore, in a theater of one thousand women, 25 will die from breast cancer.
2/
This means that if regular mammography screening was really reducing breast cancer death by 20%, more than 5 women out of 1000 have been saved by regular mammography screening (since the above numbers are in countries with national screening).

In 2016 I've discovered while working at the @Inserm (the French National Institute of Health and Medical Research) that mammography screening is a major cause of breast cancer, due to X-ray induced-radiation. I was harassed by the INSERM and lost my permanent position in 2018
2/
I received support from Archie Bleyer, Professor Emeritus at OHSU, and we could publish in the New England of Medicine some data on the consequences of nationwide mammography screening in France and in the USA (Corcos & Bleyer, NEJM, 2020).
