医学专家指出,环境污染与工业化紧密联系的生活方式的改变,是大部分恶性肿瘤患发的主要根源。尽管人们的环保意识不断增强,但是,癌症发病率仍在急剧上升,显然,注意体育锻炼以改变生活方式,是防癌、抗癌的当务之急。实践证明,经常参加体育锻炼能够增强人体的抗病能力,包括防癌、抗癌的能力。联邦德国运动医学家范阿肯教授经过研究认为,同年龄的人在同一期间,坚持体育锻炼的人,即使是患了癌症,其死亡率也比缺乏体育锻炼的人低得多。美国哈佛大学的研究人员对11所学校毕业的5398名妇女进行调查发现,平时缺乏体育运动的妇女患子宫、卵巢、子宫颈和阴道癌的病例是经常参加体育锻炼妇女的2-5倍;前者患乳腺癌人数是后者的2倍。体育锻炼之所以能防癌原因有六个:一是,体育锻炼能增强机体的免疫功能。体内的免疫功能愈强,其歼灭癌细胞的数目就愈大。同时,只有当患者体内有一定的免疫功能时,免疫药物以及药物治疗才能发挥它应有的作用。因而 Medical experts point out that the change in lifestyle that is closely linked to environmental pollution and industrialization is the main source of most malignant tumors. Although people’s awareness of environmental protection continues to increase, the incidence of cancer is still rising sharply. Obviously, paying attention to physical activity to change lifestyles is an urgent task for cancer prevention and cancer prevention. Practice has shown that regular participation in physical exercise can enhance the body’s resistance to disease, including the ability to prevent cancer and fight cancer. According to a study conducted by the federal German sports medicine scientist, Professor Van Aken, people who persist in physical exercise during the same period as those of the same age, even if they have cancer, have a much lower death rate than those who lack physical activity. Researchers at Harvard University in the United States conducted a survey of 5,398 women graduating from 11 schools and found that women who lack physical exercise usually suffer from uterine, ovarian, cervix and vaginal cancers 2-5 times more often than women who regularly participate in physical exercise; The number of people with breast cancer is 2 times that of the latter. There are six reasons why physical exercise can prevent cancer: First, physical exercise can enhance the body’s immune function. The stronger the immune function in the body, the greater the number of cancer cells that have been destroyed. At the same time, only when the patient has a certain degree of immune function, immune drugs and drug treatment can play its due role. thus
