Although you probably won't hear about it from your primary care provider or oncologist, exercise is one of the best things you can do to prevent cancer, including breast cancer. Even more interesting for women like me who have had cancer and are deemed (statistically) to be at high risk for it coming back, is that exercise may help prevent cancer recurrence, including metastatic recurrence. Recent studies have shown that regular exercise can lead to as much as a 50% reduction in recurrence rates for women who have been diagnosed with breast cancer. The most recent research has indicated that the INTENSITY of the exercise women engage in makes a difference in its effectiveness, with greater intensity resulting in greater benefit.
Although I am obviously not a good poster girl for advertising the cancer preventative benefits of regular, intense, exercise, statistically the evidence is there to support this argument. Regular exercisers have lower rates of a number of different cancers. Who's to say that I might not have been diagnosed with cancer earlier in life were it not for those years of regular running and biking? In my case the benefits of exercise were also confounded by regular wine consumption- a lifestyle behavior that my new, now more "cancer-smart," and wiser self, knows put me at significantly increased risk for developing a hormone fueled breast cancer (as well as all sorts of other cancers and health problems)- but that's for a future post.
Back to the present. Exercise is good, so good that it may be the most important thing I have done and can do in the interest of living as long as possible, maybe (if I'm lucky) even as long as my maternal grandparents who lived into their 90s. Vamos a ver...
Besides the possible utility exercise may have as a means of making one's life longer, it also, in my experience, offers the more immediately gratifying benefit of making one's life better. Exercise played a huge role in helping me get through my initial diagnosis and treatment. During those dark days last year as the process of determining the exact nature and degree of my misfortune was unfolding and it seemed for a while that at each level of exploration the answers seemed to get worse and worse, I couldn't do much to change what was happening- but I could walk- and that's exactly what I did- walked, and walked, and walked, and walked. I became the literal version of the saying about how when things are bad you just need to keep putting one foot in front of the other. I did the same thing during chemotherapy. Every day no matter how crappy and tired I felt I got out and walked at least 2 miles and sometimes as many as 5, depending to a large extent where I was in the treatment cycle and whether there was dexamethasone (a steroid drug with considerable "ramping up" effects, given in the few days after treatment to prevent nausea) involved. Thanks in part to this I got through chemotherapy without gaining any weight, in fact I lost a few pounds. This is also a big deal since weight gain during chemotherapy is very much the norm and is directly correlated to decreased likelihood of "disease free survival" (aka not dying at a later date from the cancer showing up later somewhere else in your body).
After finishing treatment last year (I had my last round of chemotherapy on October 6th 2007 and my last radiation treatment on December 19th 2007), I began working up to the more strenuous kinds of exercise I'd done in the past, mainly running and biking, but adding in swimming after a few months when my neighbor (now turned training partner) and I signed up to do the Danskin New England 2008 Triathlon. Doing the training and successfully completing the event provided me with a huge boost toward feeling healthy and more in control of my body again. I enjoyed it enough that I completed a second triathlon on September 14th, 2 days before having my second, this time prophylactic, mastectomy. Although my main reason for having the surgery was so that I wouldn't have to continue to have the remaining breast monitored or continue to have to deal with the uncertainty of a possible local recurrence hanging over me, I was also influenced by the side benefit that with no breasts instead of one I would be able look fairly normal, albeit a bit flat chested, wearing a regular athletic swim suit with no prosthesis.
Since the surgery I've been a little slow getting back into the routine of hard exercise on a regular basis. In addition to having to rest up a bit so I could heal I also had a variety of other things going on, not the least of which was opening my own independent practice and having to learn, on the fly, some of the skills of being a small business owner in addition to being a clinician. I was okay with this for a little while, the business and continuing to earn a living had to take priority temporarily. Now that that's a little more settled and things are becoming more routine I need to return to my main priority which is taking care of myself and doing all I can to live well and live long. Now that I am working only for myself I notice that time management is a real challenge and it is easy to put off exercise thinking that I will have time to do it later in the day because after all I make my own schedule. It really hasn't worked this way, especially now that it's dark out before 5:30 pm.
One of the great things about being a psychologist is that I have all sorts of knowledge that I can sometimes, when I'm being smart about it, apply to myself. This month I've decided to apply what I know about the benefits of setting clear goals, having a routine, and exercising early in the day, in order to get back on track. For this month I am going to exercise every morning first thing as part of my new morning routine- either getting out for at least a 30 minute speed walk, run/walk, or run. If more exercise happens later in the day that's great, "gravy" as they say, if not fine, I've gotten a workout in.
For those of you inclined to comment, especially women previously diagnosed with breast cancer, I am interested in hearing about ways that you have structured your life in ways that make it easier to take care of yourself, whether it's in the realm of exercise, diet, or other self care activities.
