目前,晚期癌症是不治之症,人们对这种病比较关注。医生对患者采取药物和手术治疗也采用放射性疗法。放射性治疗(如镭射线)对早期癌症有一定疗效,但对晚期癌症仍不能治愈。国外有资料报导,尝试用π~-介子射线治疗晚期癌症,已治愈多例。本文试从生物—物理角度论述其理论依据。 At present, advanced cancer is an incurable disease. People are more concerned about this disease. Doctors also use radiation therapy to take medications and surgical treatment to patients. Radiation therapy (such as radium ray) has a certain effect on early cancer, but it is still incurable for advanced cancer. Abroad, there are data reports, try to use π ~ - meson radiation treatment of advanced cancer, has been cured in many cases. This article tries to discuss its theoretical basis from the biological-physical perspective.
