If spending my days as a hospice and palliative care physician has taught me anything, it’s that cancer is everywhere. Obviously, I deal with cancer patients on a daily basis, but it seems that even in my personal life, few weeks pass without hearing of someone else receiving the diagnosis. Part of it is my age. As I get older, I’m inching into the demographic where the incidence is rising. Also, I become more aware of my own mortality, so I take notice more than I did in my twenties. However, the truth is that the incidence of cancer is increasing. The reasons are multi-factorial and too complex to dissect here.
The other thing I continue to notice is that while modern medicine is pretty good at treating acute illnesses, we stink at prevention. This has led me to dive deeply into disease prevention over the last few years. The point as it relates to cancer is that two thirds of cancer can be prevented with lifestyle modifications (nutrition, exercise, don’t smoke, etc.). It is estimated that one-third of cancer can be prevented with routine exercise alone. The reason is not some nebulous process where exercise magically prevents problems. It is a very complex, but real, set of processes that occur with regular exercise that are being elucidated more and more each year. There are numerous physiologic, neuro-hormonal responses that are beyond the scope of this discussion that help prevent the equally real processes that lead to cancer development. This link is to the National Cancer Institute’s informational page on physical activity and cancer. It’s very basic and I encourage everyone to glance at it and see if you can find the motivation to get moving!
