Dear Grace,
Thank you for what you have shared, my daughter is also threatened by the predictors. I would like to see your publication. I appreciate the wisdom and grace with which you have shared and the accuracy with which you have captured the threat and yet have moved forward in science, simply and elegantly stating things as they are. I hope that that the answers are explicated and put into practice in your lifetime.
Be Well
Amy

Hello all,
I am going to speak from three foci. One as a registered nurse who has taken care of patients who are diagnosed with and treated for breast cancer. Two, as a nurse scientist who studies all aspects of breast cancer, as well as other areas of healthcare concern. And three, and probably most importantly to me, right now, as a person with a recurrence of advanced stage breast cancer. And, interestingly, both diagnoses were found serendipitously – not because I didn’t have mammograms done, but because I had “interim” tests done for another screening, when the cancerous cells were “seen”.
I have many comments about this thread, but have received some interest in a publication related to this, so am not going to bore you with ALL my thoughts and info; besides this response would be way tooo long by then.
Primarily, my comment relates to all three of these roles: it isn’t so much the discovery of the breast cancer nodes that is as important as the importance of recognizing that each of those discovered nodes very likely has yet to be undiscovered cells, and those cells grow to be discovered – and that is when we are diagnosed, treated, and scared. It is akin to the “just noticeable difference” that we discuss in some measurement methods. We have to look in different ways, and harder for those cells – or other markers - that are not yet seen but that could be predictors.
We absolutely need more specific and precise methods of discovery of all kinds of cancer cells. FYI for those of you that may not know, there is a large scale study going on right now in the US called “The Sister Study”. The study examines number of variables that would help identify people who have a higher probability of “getting” cancer; hopefully, some markers may be identified from this project. The study follows a large cohort of women who are sisters of women who have been diagnosed with BC. This has been ongoing for some time now, and we may see some preliminary results soon.
Klim, I strongly agree – we need to garner the support for erring on the side of over testing, (as opposed to over diagnosis).
Folks, let’s keep talking about this issue from both a scientific approach as well as a patient-centered approach.
Thanks for the thread, and for listening.
Everyone, have a wonderful Holiday season.
Grace

In the process of knowledge discovery, what is known about a concept must be qualified to ensure understanding before that concept can be used for making judgements or conclusions. Thus, concepts must be examined for their characteristics and usage, with the goals of common understanding, consistent communication and theory development in mind (Rodgers & Knafl, 2000).

Klim,
I see what you mean...Do you think if women were more accurately informed to build acceptance along with the screenings as a public health service for 2-3 years and if RR etc was taught in school health classes and a public information with decision aids was offered that this could build a bridge. I think once women get past the emotion they would want to know and would be more accepting of improved diagnostics?

Amy,
I am sure a research protocol to render a test more specific about intrinsic malignancy could be devised. However the basic problem here is that screening carries so much face validity and therefore so much 'emotional' support that to devise and institute such a protocol is hindered by the need to explicitly acknowledge the possible existence of over diagnosis, over and above the issues associated with DCIS. Thus to do so has a certain heretic component that does not, and will not, help. First we need a greater degree of acceptance of the need to do so.

Klim,
It was your initial response that kept me thinking and returned me to the land of reason. I wonder if it would be worth using markers and tracking the cells overtime with a segment of the population. Klim what would you envision as strategies to solving this complexity?
Andy, I really appreciate both the breast and prostate decision aids, these are the best I have seen...great work I like how you have explained the risk factors and the graph is outstanding without being overwhelming.
Paul, these papers are excellent and I learned a lot from reading them that I hope to apply later!
Jo, The lawyers information site was surprisingly informative maybe it is time to merge all for a blog article
Thanks to all for your help and understanding, You are awesome
Best,
Amy

Amy,
The whole current controversy surrounding mammography centres on the issue of overdiagnosis. Does it exist if so how common is it? Without doubt removing tumours is much better than not and the earlier the clinical stage the better the survival experience – again without doubt. The evidence is overwhelming. But the question is are there some tumours for which treatment is unnecessary – to which the answer is probably yes, and there may be many. But deciding which is not anywhere near reliable enough right now. Hence the controversy. In my view the guidelines are woefully inadequate and I think women are not given anything like enough information to take proper decisions on an impossible question. That however is no excuse in my view.

Dear all,
Does anyone know how to find out if people who have breast cancers removed have a higher longer survival rate than those who do not? The question was raised that perhaps those with lesions and successful surgery could have perhaps left them in there with no ill results? The thinking was that if it is cancer within a set number of years they will die anyway with or without intervention.
I was too emotionally invested to look at this clearly initially however wilful ignorance does not solve problems but can be a source of alienation. What evidence is there that screening and consequent treatment is not helpful? I do understand that mass screening may be a waste of resources in terms of numbers needed to treat but it seems that the suggested guidelines seem to be evidence starved as well.
Many thanks if someone could direct me to helpful links in this area.
Best,
Amy
