医学研究人员巳开始进行合成激素的实验研究。这些激素可有效地阻断有害物质的分泌。研究者希望此方法能更好地治疗许多常见病。对于一些癌症病例,这种新方法可能代替必需的手术。一些合成激素能阻止生长缓慢的肿瘤分泌有害激素。另一些合成激素则因切断了肿瘤所需激素的产生而抑制肿瘤。这些激素正有效地治疗脑和小肠一些少见的肿瘤以及 Medical researchers started the experimental study of synthetic hormones. These hormones can effectively block the secretion of harmful substances. The researchers hope that this method can better treat many common diseases. For some cancer cases, this new method may replace the necessary surgery. Some synthetic hormones can prevent slow-growing tumors from secreting harmful hormones. Other synthetic hormones suppress tumors by cutting off the production of hormones required for tumors. These hormones are effectively treating some rare tumors in the brain and small intestine, as well as
