Physical Activity Significantly Extends Lives of Cancer Survivors

Physical activity significantly extends the lives of male cancer survivors, a new study of 1,021 men has found.
During the period while the men were followed, those who expended more than 12,600 calories per week in physical activity were 48 percent less likely to die than those who burned fewer than 2,100 calories per week.
Kathleen Y. Wolin, PhD, of Loyola University Chicago Stritch School of Medicine, is co-author of the study, published in the Journal of Physical Activity & Health, the official journal of the International Society for Physical Activity and Health.
Many cancer survivors are living longer, due to earlier diagnosis and better treatment, and their numbers are increasing rapidly. “Thus physical activity should be actively promoted to such individuals to enhance longevity,” researchers concluded.
There has been extensive research showing that among generally healthy, cancer-free populations, physical activity extends longevity. But there has been relatively little such research on physical activity among cancer survivors.
Researchers examined data from the Harvard Alumni Health Study, an ongoing study of men who entered Harvard as undergraduates between 1916 and 1950. Researchers looked at 1,021 men (average age 71) who previously had been diagnosed with cancer. In questionnaires conducted in 1988, men reported their physical activities, including walking, stair-climbing and participation in sports and recreational activities. Their physical activities were updated in 1993, and the men were followed until 2008.
Compared with men who expended fewer than 2,100 calories per week in physical activity, men who expended more than 12,600 calories per week were 48 percent less likely to die of any cause during the follow-up period. This finding was adjusted for age, smoking, body mass index, early parental mortality and dietary variables. (By comparison, a 176-pound man who walks briskly for 30 minutes a day, five days a week burns 4,200 calories.)
There were similar findings for mortality from cancer and cardiovascular disease: the most physically active cancer survivors were 38 percent less likely to die of cancer and 49 percent less likely to die of cardiovascular disease during the follow-up period.
Wolin is an epidemiologist. She is researching the role that exercise, obesity and other lifestyle-related factors play in the prevention of cancer and in improving outcomes after diagnosis. She also is studying how to improve outcomes once a disease is diagnosed. She earned her ScD from Harvard, and now is an associate professor in the departments of Public Health Sciences and Surgery at Loyola University Chicago Stritch School of Medicine. Wolin’s team is recruiting colon cancer survivors for a home-based strength-training intervention.
First author of the study is I-Min Lee of Harvard Medical School. Other co-authors are Sarah E. Freeman of the Harvard School of Public Health, Howard D. Sesso of Harvard Medical School and Jacob Sattlemair of Boston, Ma.

Diabetes and smoking

Postby Marion » Mon Mar 14, 2016 2:03 pm

Six months ago I was diagnosed with type 2 diabetes. At the time my blood sugar was at 25. My oncologist put me on 2000mg. of Metformin and 60 mg. of Gliclazide per day. My blood sugar level went down to an average of 5 or 6 per day. My doctor still wants me to loose weight and do more exercise to loose weight.
My main concern is that I am a chain smoker

and I don't exercise enough. Every spring and every fall I get bronchitis. I worry that one of these days I may be diagnosed with lung cancer as well. I am starting to walk around the block every few days but that is the extent of my exercising. I am taking a dietary supplement called Belly Trim XP and have lost about 5 or 6 pounds in my gut. I feel good about that. I have also started using an e cigarette. I use it more when I am outside because the extra humidity in the air prevents me from coughing while using it. If I use it indoors in my apartment the air is too dry and I am prone to coughing when using my e cigarette. What I have done is reduce the wattage setting on the unit which makes it more bearable. My only problem is that I am still addicted to cigarettes. I average 15 to 20 a day. I just can't seem to quit yet. Am I doomed to get cancer in the end??
