Nowadays, many young women also get breast cancer. If premenopausal women do a series of moderate-intensity exercises, they can reduce their risk of breast cancer by up to 10%. [사진=게티이미지뱅크]One study showed that physical activities such as walking and cycling can reduce the risk of breast cancer by up to 10% in young women under the age of 45.
The Institute for Cancer Research (ICR) in London, UK, said this was the result of a survey of around 547,000 women who had not entered menopause. The research team analyzed data from 19 research articles around the world, including the “Breast Cancer Now Generations Study”. Additionally, the physical activity level and cancer diagnosis of premenopausal women, who were followed for an average of 11.5 years, were studied. During this period, 10,231 out of 547,000 people (about 1.9%) were diagnosed with breast cancer.
“Many of the factors that influence breast cancer are outside of our control,” said lead author Dr. Michael Jones. “Exercise can significantly reduce your risk of breast cancer, so that’s a huge benefit.”
According to study results, women who did more physical activity, such as walking (top 10 percent), had a 10 percent lower risk of developing breast cancer before menopause than women who did less (bottom 10 percent). Bass). During the analysis, the research team considered other breast cancer risk factors and lifestyle habits, such as family history of breast cancer, body mass index (BMI), smoking and alcohol consumption .
The research team said: “There is no specific amount of physical activity that women need to see the effects of physical activity. However, the more people engage in moderate to vigorous exercise in addition to work-related physical activity, the lower the risk of breast cancer.” Active physical activity lowers sex hormones such as estrogen and testosterone, as well as insulin and growth hormone levels, which can promote the growth of breast cancer. It also reduces inflammation, which is associated with the development and progression of cancer.
According to the research team, breast cancer is more common in older women, but in the UK 5,000 young women under the age of 45 develop breast cancer every year. Breast cancer in younger women is more aggressive and tends to be diagnosed at a later stage. According to National Cancer Registration Statistics (2020), approximately 50% of breast cancer patients in Korea develop before menopause (average age 50 years). In particular, the percentage of young breast cancer patients under the age of 39 reaches 11%. There is an urgent need to find new ways to prevent breast cancer in young women.
The results of this study (International Pooled Analysis of Leisure-Time Physical Activity and Premenopausal Breast Cancer in Women From 19 Cohorts) were published in the Journal of Clinical Oncology published by the American Society of Clinical Oncology.
