Inflammation's Newly Recognized Role in Cancer

Inflammation helps promote healing. But chronic inflammation can play a role in various diseases, and researchers are beginning to appreciate that inflammation may help tumors grow and spread. Anti-inflammatory medications could be the next wave of cancer drugs. Steve Mirsky reports.

The medical dictionary definition of inflammation is the reaction of a part of the body to injury or infection, characterized by swelling, heat, redness and pain.  The process includes increased blood flow with an influx of white blood cells and other chemical substances that facilitate healing.  So inflammation is good.  Except when it’s bad.  In the past 15 years, the medical community has realized that inflammation contributes to heart disease, by helping to form arterial plaque, and to diabetes and possibly even to depression. 

And according to an article in the July issue of Scientific American, more and more researchers are coming to the realization that inflammation may also play a crucial role in the development of cancer.  Until recently, genetic changes were the primary focus of cancer study.  But in the last decade it’s become clear that developing tumors can take over some of the molecular apparatus of inflammation and use it to grow and spread.  The good news is that this realization opens up a new realm of possible anticancer drugs.  Anti-inflammatory medications might have the potential to stop new tumors in their tracks.

It’s Time to Stand Up for Science

If you enjoyed this article, I’d like to ask for your support. Scientific American has served as an advocate for science and industry for 180 years, and right now may be the most critical moment in that two-century history.

I’ve been a Scientific American subscriber since I was 12 years old, and it helped shape the way I look at the world. SciAm always educates and delights me, and inspires a sense of awe for our vast, beautiful universe. I hope it does that for you, too.

If you subscribe to Scientific American, you help ensure that our coverage is centered on meaningful research and discovery; that we have the resources to report on the decisions that threaten labs across the U.S.; and that we support both budding and working scientists at a time when the value of science itself too often goes unrecognized.

In return, you get essential news, captivating podcasts, brilliant infographics, can't-miss newsletters, must-watch videos, challenging games, and the science world's best writing and reporting. You can even gift someone a subscription.

There has never been a more important time for us to stand up and show why science matters. I hope you’ll support us in that mission.

Thank you,
