Shell Oil should donate the oil it purchased from Russia to the Ukraine.

Agree completely. But there's so much more to do. Start by removing barriers for women in their 40s to get screened. Save more lives and reduce suffering. Open Ontario breast screening to women in their 40s now.

October is #BreastCancerAwarenessMonth. About 1 in every 8 women will develop breast cancer in their lifetime. Early detection is critical. This month, let’s take a moment to remember those we’ve lost, honour the survivors, and support those still fighting.

Why is @Cantaskforce member Scott Klarenbach propagating inaccurate information to Family Doctors on breast cancer screening? He is undermining a lifesaving tool where benefits>>> harms. Political agenda or just his lack of knowledge? Either way, dangerous to our health!

Methinks @cantaskforce doth protest too much. Instead of self-congratulatory tweeting, they should do their homework, read the modern science and replace their dangerous breast screening guidelines that will harm women.

It's truly outrageous that given the flawed breast screening guidelines by @cantaskforce and the outcry from 65,000 concerned individuals, Minister Petitpas Taylor and Dr Theresa Tam haven't acted yet to review its governance, claiming "arms length". This is their responsibility!

Women have a right to know if they have low, mid, or high density breasts, so they can know if their mammogram is reliable - take charge of their health and discuss w health provider. Consider ultrasound if they have very dense breasts. Ontario policy out of date!

Regular mammography screening saves lives for women 40 and older, but is less accurate in dense breasts. Density also a risk factor for br cancer. Based on my old 1980s research w Dr. N Boyd, Ontario only tells women when their density is over 75%. This is antiquated ....

Minister Petipas Taylor distancing herself from dangerous Task Force Recs good first step. Now she must step up and revamp dysfunctional TF.

@DonDavies Over 50,000 Canadians agree with Don Davies and signed a petition demanding the guidelines be removed.

Canada's new breast cancer screening guidelines ignore breast density and recommend against self-examination and timely mammograms. They will cause over 400 women to die unnecessarily every year. The federal government has a responsibility to fix these dangerous guidelines.

Instead of endorsing (or even worse, following) dangerous Canadian Task Force Recs. on Breast Screening, Physicians should follow the lead of our Federal Health Minister, Ginette Petipas Taylor, who in Parliament distanced herself from the Task Force. A good first step.

It's time to respond to @cantaskforce Canadians deserve better guidance on breast cancer screening! My concerns are described in open letter to Task Force at goo.gl/4i8UBt Sorry it's so long. Let them know what you think.

Very poor judgement by @cantaskforce in posting biased anti-screening video. See my critique at goo.gl/np7wLe @carlyweeks thinks this is a balanced presentation! - she needs to do some homework (I'd be glad to give her reading list). CTF has let Canadians down.

@cantaskforce had the opportunity to present benefits and risks clearly and accurately, but chose to cherrypick data, incorrectly overestimating risks and ignoring modern data on benefits. Not too late to correct this! Read the literature.

Better outcomes? Here's how: 1) Screening that is able to reduce incidence of advanced cancers by earlier detection is strongly associated with mortality reduction. 2) Breast ultrasound, MRI, contrast-enhanced dig mammography find cancers in dense breasts missed by mammography
Carly Weeks@carlyweeks

I wrote about breast density, a known risk factor for breast cancer, and the push to ensure women know whether they have it. The problem? There is little evidence showing that extra screening for tissue density will lead to better outcomes. theglobeandmail.com/canada/article…

@DrBridgetOBrien This was not an RCT. Read Prof Harry de Koning's critique of this study to learn why it has very limited value. By the way, do we know how many of the breast cancer deaths were from screen-detected cancers? Same problem with Bleyer-Welch overdiagnosis paper using SEER data.

@DrBridgetOBrien Statement based on really naive assumptions by M. Baum who demanded proof that all-cause mortality is reduced by breast cancer screening. Simple statistics! This would require randomized trial of several hundred thousand women, even if screening totally eliminated br cancer.
