50年前,癌症还是鲜为人知的疾病,而到了今天,则是尽人皆知。现代医学对癌症的认识,也与几十年前不同了。在20世纪的四五十年代,癌症(即恶性肿瘤)确实是不可治愈的疾病。比如,那时发生在女性身上的绒毛膜上皮癌(简称“绒癌”),几乎是发现一个死一个,没办法治。然而,随着化疗手段的进展,现在患“绒癌”的病人,80％以上可以治愈。因此,现在可以说,癌症已是一种可防、可治的疾病了。 Fifty years ago, cancer was still a little-known disease. Today, it is known to everyone. The understanding of cancer in modern medicine also differs from that of a few decades ago. In the 1950s and 1950s, cancer (ie, malignant tumors) was indeed an incurable disease. For example, choriocarcinoma (“velvet cancer”), which occurred in women at that time, was found to be almost dead and could not be cured. However, with the progress of chemotherapy, more than 80% of patients suffering from choriocarcinoma can be cured. Therefore, it can be said that cancer is already a preventable and treatable disease.
