不良心理是种种肿瘤病的诱发因素。有研究发现,心理紧张、在精神压力很大的恶劣环境中工作的人,患结肠癌、直肠癌的机率竟是工作环境好心情平均者的55倍。科学界因此认为,保持积极健康的精神状态,能减少患癌的机会,并推测,已患癌症的病人通过调整心理措施也可大大增强自身的抗癌能力。一些科学工作者试图通过这种方法寻找治癌的新途径。英国的沃克教授与阿伯丁大学有关学者对80名患乳癌的妇女进行研究,让 Unhealthy psychology is a predisposing factor for various tumor diseases. Some studies have found that people who work in stressful situations and work in stressful and stressful environments have a 55 times higher chance of developing colon cancer and rectal cancer. The scientific community therefore believes that maintaining an active and healthy mental state can reduce the chance of cancer, and speculates that patients who have suffered from cancer can also greatly enhance their cancer-fighting ability by adjusting psychological measures. Some scientists try to find new ways to treat cancer through this method. Prof. Walker of the United Kingdom and Aberdeen University scholars studied 80 women with breast cancer.
