신체활동이 암에 미치는 영향 : 대장암, 유방암, 전립선암에 대한 역학(疫學)연구를 중심으로 = Effects of physical activity on cancer - Focusing Mainly on Colon, Breast and Prostate Cancer -

다국어 초록 (Multilingual Abstract)

Many efforts have been carried out to cure and treat cancer, but there are still a constant increase in death ratio due to cancer. The prevention of cancer is the most important thing because cancer is the fatal disease. There are many ways to prevent cancer, physical activity is one of them. Many studies have investigated the relationship between physical activity and cancer. The results of these studies are as follows; there is around 40-50% less chance of getting colon cancer, 30-40% for breast cancer, and 10-30% for prostate cancer. Even with all these studies it was hard to find Korean studies investigated the relationship between physical activity and cancer.
The prevalence rates of cancer are hugely variable due to the difference of gender, ethics, diet habit and physical activity. So it is needed that studies should be done for each ethical group.
The variation of physical activity is huge and it depends on many various factors: intensity, frequency, duration, and type. For this reason, it is hard to estimate the total physical activity accurately with large population in a long term study. The inconsistent results could be attributed, in part, to methodological issues, including crude assessment of physical activity.
Therefore further studies should be performed to develope more precise methods of estimating total physical activity and investigate the relationship between physical activity and cancer for reducing cancer with Koreans.
