Dr. H. Gilbert Welch (Dartmouth) & Dr. Archie Bleyer (OHSU) found in their study, published in The New England Journal of Medicine, that alarming numbers of women are enduring body and life altering treatments for cancers that would not have affected them negatively in their lifetimes.
Apparently pathologists can't distinguish the non-aggressive from the lethal breast cancers.
So all cancer is treated as if it will progress. We're finding double the early and not less late stage breast cancers, says Welch. That's a big problem of over-diagnosis, over-treatment leading to harm, not to mention inflated cancer rates and all kinds of tricks being played with numbers to scare us, says this mathmetician, general internist, & public health advocate.

Overdiagnosis is explained in this Dallas Morning News article by Welch Too Many Mammograms Don't Help and also in these 4 short videos by Welch:
Welch authored these books:
“This thought-provoking book offers a unique perspective on cancer screening.”—Barbara Bibel Library Journal
“Intelligent and eminently readable . . . a timely reminder that screening is not all it’s all cracked up to be. This is a book that should be read by all healthcare providers and all symptom-free individuals who are being coerced into a screening test.”—Michael Baum New Scientist
Hear Welch in the Debate Over The Benefits Of Routine Mammograms, an amazing exchange about perhaps the most controversial medical issue today, the value of mammography screening. It includes these participants:
As an example of harms of screening, Welch uses the prostate cancer "epidemic" that led to surgeries removing prostates before we knew prostate cancer isn't always life-threatening, and certainly not worth losing bladder and sexual function in asymptomatic healthy men.
In this 2015 interview on Science Friday Avoid the Doctor - For Your Health Welch discusses how technology advances of seeing tiny things set us up for radical treatment before symptoms arrive and may not ever..
