Once More: Exercise
I know. I know. I write about this all too often, but it continues to cross my desk, and every now and then I even hear from someone that my constant carping on this topic has been motivating. (Thank you, Patricia). I think, too, that I am feeling somewhat guilty this morning as I did not make it to the gym. I had an early morning meeting at work, and there is just no way that I can get up, go to the gym, shower (And did I mention that we had no hot water this morning? At least it is not January!), drive to work and be here by 7:00 AM. Rationally, I know that missing an occasional day does not matter, but I am so obsessive about my routine that I fear missing days. I think the worry is that missing one work out will make it easier to miss the next one. Hopefully, I will be back on the elliptical machine tomorrow morning.
Anyway, here is a short piece from Nature about the benefit of exercise for women post adjuvant treatment for breast cancer. New to me is the suggestion that exercise may be particularly useful for women who have ER positive breast cancers. Here is an excerpt and then a link:
Exercise: Powering Up
AFTER THE FACT
For those who have received a diagnosis of breast cancer, there is also evidence that exercise can improve disease outcomes. A metaanalysis of six studies that included more than 12,000 women with breast cancer concluded that taking up exercise after diagnosis cuts the risk of dying from the disease by 34% (and of dying from any cause by 41%), within the 9-18-year time frame of the studies.
By contrast, in the same meta-analysis, women who exercised before diagnosis were 18% less likely to die in a given period than inactive women, but there was no difference in the rate of breast cancer deaths.
In two of the six studies, there was an indication that only women with a body mass index (BMI) greater than 25 benefited from exercise after diagnosis. The two studies that took into account the oestrogen-receptor (ER) status of the tumours found that women with ER-positive tumours were the only subgroup to benefit from post-diagnosis exercise. While not conclusive, these associations do suggest pathways that might be involved in mitigating cancer risk.
