Breast density has something to do with breast cancer. This is not really news. It's clear there is some kind of link, some kind of relationship, some kind of risk related to breast density for both pre- and post-menopausal women. It's just not clear how exactly breast density -- how much fat tissue fills the breast compared to other tissue -- contributes to breast cancer risk. But once it is clear, medical professionals will have a whole new arsenal of power in the fight against this deadly disease.

Cancer News in Context, a regular series of podcast commentaries produced by the Harvard Center for Cancer Prevention, highlights two recent studies that add weight to the fact that breast density is an important tool in breast cancer prediction and identifies two areas that with futher study might help determine why breasts that are very dense are associated with higher risks for breast cancer -- and why density may be as important a factor as age in determining risk.

Currently, mammograms are the chosen method for measuring breast density. But measurement is not required, and there are no national standards for how to measure. Once federal groups issue requirements and direction on how to classify density, women will receive more accurate assessments of their personal risk.

There is also speculation that altering breast density through hormonal therapy may lower risk. Perhaps genetics are the strongest indicator of risk, making short-term solutions ineffective, but perhaps certain interventions can override genetics, helping women protect themselves from breast cancer.

There are many issues that must be ironed out before we really understand how breast density affects breast cancer. There is no doubt that density, when added to other risk factors, will surely help improve the accuracy of prediction. It's one tool, among many, that is poised to open all sorts of doors.

I was in my oncologist office yesterday and noticed a new poster hanging on the wall advertising an on-line system for managing health care -- for scheduling appointments, confirming appointments, locating test results, paying bills, and more. Founded in 1999 and headquartered in Emeryville, California, RelayHealth is the premier provider of secure on-line healthcare communication services that link patients, healthcare professionals, payors, and pharmacies in matters that are medically non-urgent. The website also features news and customer stories and aims to improve the delivery and accessibility of healthcare to patients -- in a seamless manner.

I haven't done much with this service yet -- but I did take a short tour and made a simple search for my physician whose information promptly popped up on my screen. That part was easy. And once I register with a username and password, I will have more access to more information pertaining to me and my healthcare team. And you can too.

I sometimes complain about the lack of warmth I've encountered from medical professionals throughout my journey with breast cancer. There have been glimpses of compassion. And there are a few who stand out as truly caring and concerned. But there seems to be a general lack of sensitivity. Maybe it's a side effect of the job -- distance -- that I should have been prepared for. But instead I was shocked by how I often felt forgotten, like a number, just one of many in my same boat. And this makes me sad -- for me and for all the others who sail rough waters in search of health. I have waited in lobbies for hours -- four hours one time -- and I've been encouraged to toughen up. I've rarely felt comforted -- except by a few who have hugged me or placed a hand on my shoulder. That's all it takes. A simple gesture or kind word.
