Cool study!

An enzyme that blocks breast cancer? -- see here

The LA Times today mentions a study by USC researchers that found green tea to block the effects of a specific kind of chemo agent used on multiple myeloma and a couple of other cancers--not breast cancer, though. Green tea is an antioxidant (perhaps it would be more precise to say it contains antioxidants) that are effective at preventing breast cancer, and it may even aid in the treatment of breast cancer. Although some very conservative oncologists, such as the local practice near where I live, don't want their patients using green tea or other antioxidants during chemo, I found a substantial amount of research showing that green tea actually aided the effects of chemo. It may help chemotherapy target cancer cells better, while protecting non-cancer cells and thus easing the damaging effects on the body. (Note that I am linking to a layperson-friendly page, not to one of the studies, but a quick Google search will get you the real research.)

I'm very happy to say that I was treated at USC, which--this study notwithstanding--seems more open to green tea; I wasn't treated at the local practice.

Just wanted to share!

The Case of the Disappearing Cancer

I've been sent articles several times already about this Norwegian study that concluded that some breast (and other) cancers may spontaneously disappear, without treatment. I don't really have much comment of my own, because before I could really think deeply about the study, I read this fantastic response by a "skeptical OB-GYN," who writes a terrific, point-by-point analysis. Some highlights:

The study only looks at incidence of cancer. It does not look at outcome and life expectancy. If it turns out that the women in the study group have a much lower incidence of death from breast cancer, because they are treated early and aggressively, it will justify the apparent over diagnosis of breast cancer.

And,

there is no way to tell the difference on mammography, or by any other technique, between the cancers that will disappear and the ones that will go on and kill the woman.

To me, these two quotes really say everything we need to know at this point. However, as winter comes and my summer tan fades, and I note in the mirror greater evidence of the premature aging effects of chemo; as I read on the web that a close family member's kind of lung cancer is often treated with Taxol, and I think back on the bone pain and the horrible allergic reactions; as I think about the months of my life "lost" to sitting miserably on the couch; as I think of the awfulness that is cancer treatment, I certainly hope that researchers follow up on this study and find a way to make the important distinctions. Let's get rid of chemo for anyone for whom we can!

In the news

I have certainly been reticent lately. (That's reticent, not reluctant!) The blessing and the curse of being back to "normal life" is that I am mired in the quotidian tasks of work and errands. The good news is, we will be going on vacation in a couple of weeks, to Northern Italy, Slovenia, and Croatia. I am very excited. It'll be a 3-week trip, hitting lots of lovely places (Alps, Venice, seaside Istrian resorts...). And our house and dog won't be lonely, since there will be visitors throughout our time away, enjoying the beach life in our absence.

But I'm here for business, so let me get to it. The other day, NPR had a very interesting story about a new study (published in JAMA if you want to go get the actual study; full paper here, subscription required; the NPR audio is here) regarding diagnostic technologies. Apparently mammography plus ultrasound found 28% more tumors in women with dense breast tissue (like me!) than did mammography alone. That's a rather whopping increase, I think. The procedure was recommended (by the authors) primarily for women at high risk, rather than those undergoing routine screening. As someone who's already had breast cancer, some sources say that I am at high risk, so I will be talking to my doctor before my next annual mammogram!

And a second important story. Now people--does anyone out there really still not get it that we need to exercise? That we really, really need to? That all the rationalizations and justifications in the world do not prevent breast cancer, but that moving our butts even a little bit will start to help, and moving them a lot will really help? (Plus all those other benefits, like fitting into jeans.)

Anyway, now I hope that everyone with a daughter starts to make it a priority to be sure that she does not sit on her own butt, become a couch potato, shun PE (as I did!!), or otherwise grow up without learning that physical activity is a really fantastic part of life. If you can't do this for her enjoyment, then do it for her life. Another new study published this week found that adult breast cancer risk was substantially cut for women who had exercised as girls and teenagers. That's right--it's not enough to turn women loose to discover exercise once they're grown. We need to start them early, so that the next generation can have a better shot at avoiding induction into the Breast Cancer Club.

I hope all my friends, family, and kind readers will take this to heart for the young women-to-be whom they love!
