目的:探讨血型、年龄和膳食因素与乳腺癌发生和预防的关系。方法:通过对195名乳腺癌患者进行血型、年龄和膳食情况进行问卷和病案调查,数据采用2χ检验进行分析。结果:乳腺癌患者的发生与A、B、O、AB血型的关系与对照组比较差异无统计学意义(P>0.05);通过对195名患者的年龄分布分析表明,<20岁乳腺癌患者极为罕见,40~50岁妇女患乳腺癌的可能性最大,>50岁随着年龄的增高发病风险逐渐降低,>70岁妇女患乳腺癌的可能性很小。结论:乳腺癌的发生与A、B、O血型无关,高脂肪、高动物蛋白摄入患乳腺癌的危险性增高。提示40~50岁的女性要按时查体,早发现早治疗,同时低脂肪、低动物蛋白饮食、高纤维素摄入可减少乳腺癌的发生。
Objective: To investigate the relationship between blood type, age and dietary factors and the occurrence and prevention of breast cancer. Methods: Questionnaires and medical records were performed on 195 breast cancer patients by blood type, age and diet. The data were analyzed by 2χ test. Results: There was no significant difference between the incidence of breast cancer and the blood type of A, B, O and AB compared with the control group (P> 0.05) .According to age distribution analysis of 195 patients, breast cancer patients <20 years old Very rare, 40 to 50-year-old woman is most likely to breast cancer,> 50-year-old with age, the incidence of risk decreased gradually,> 70-year-old woman is unlikely to breast cancer. Conclusion: The occurrence of breast cancer has nothing to do with the A, B, O blood group, and the risk of high fat and high animal protein intake in breast cancer is increased. Tip 40 to 50-year-old woman to check the body on time, early detection and early treatment, while low fat, low animal protein diet, high fiber intake can reduce the incidence of breast cancer.
