癌症,被称为本世纪最凶恶的一大病魔,无数的科学家在不懈地努力,寻求准确诊断和治疗癌症的方法。近年来,随着对染色体研究的深入,各种致病基因不断被发现。科学界在利用基因技术诊断和治疗癌症问题上也有了新的突破。目前,染色体解析不仅能阐明导致多种遗传性疾病、早老性痴呆症、糖尿病等基因变异情况,在诊断和治疗癌症方面也有了进展。八十年代末,美国食品和医药管理局批准将基 Cancer, known as the most vicious disease in this century, has made unremitting efforts to find ways to accurately diagnose and treat cancer. In recent years, with the deepening of chromosome research, various pathogenic genes have been discovered. The scientific community has also made new breakthroughs in the use of genetic technology to diagnose and treat cancer. At present, chromosomal analysis can not only elucidate genetic mutations that cause multiple inherited diseases, Alzheimer’s disease, and diabetes, but also make progress in the diagnosis and treatment of cancer. In the late 1980s, the U.S. Food and Drug Administration approved the
