Breast density and mammograms: New FDA rule will ensure all women have more information after cancer screenings

The FDA’s rule change requires that all women in the US be informed about breast density and options for supplemental screening.

Ignoring reason and evidence: Why new breast cancer guidelines advising against screening women in their 40s are misguided

Early detection is crucial in the fight against breast cancer. Yet the Canadian Task Force on Preventive Health Care’s new guidelines do not endorse breast cancer screening for women in their 40s.

What breast cancer risk assessments can tell you

The FDA’s rule change requiring providers to inform women about breast density could lead to a flurry of questions

Dense breast tissue is common and normal, but it can make cancer more difficult to detect. FDA requirements going into effect in September 2024 will dictate that patients be better informed about it.

Biopsies confirm a breast cancer diagnosis after an abnormal mammogram – but structural racism may lead to lengthy delays

Early detection of breast cancer is critical to improving chances of survival. But racial and ethnic minority patients systematically have delayed diagnoses that reduce the benefits of screening.

29,000 cancers overdiagnosed in Australia in a single year

New research estimates 24% of cancers in men that were detected in 2012 were overdiagnosed, meaning they never would have caused harm if left untreated.

Routine mammograms do not save lives: The research is clear

October is breast cancer awareness month. Women should know there is no reliable evidence that routine mammograms reduce death from breast cancer, and there’s good evidence that they cause harm.

Three questions to ask about calls to widen breast cancer screening

Calls to routinely offer breast cancer screening to more women might sound like a good idea, but can harm. Here are three questions to ask when figuring out whether more screening really is better.

Women should be told about their breast density when they have a mammogram

Women with dense breasts are more likely to develop breast cancer. Density also makes it harder for doctors to detect breast cancer on a mammogram.

Most people want to know risk of overdiagnosis, but aren’t told

Researchers have been talking about the dangers of overdiagnosis for some time. But now a national survey shows most people aren’t told about the risk it poses to their health – and they want to know.

The mystery of breast cancer

Major causes have been identified for most common cancers, like liver and lung. But we still haven’t identified one for breast cancer.

Great expectations: our naive optimism about medical care

“It might do me some good and it won’t hurt to give it a go.” How often have you heard a phrase like this? Most people have naïve optimism about medical care. That’s the finding of a systematic review…

How does breast density impact on cancer screening?

We’ve known for some time that women with dense breasts are at higher risk of breast cancers that are difficult to detect by mammography. To address this problem, 19 US states have introduced laws requiring…
