人过40岁之后,每年都应该进行一次防癌健康体检。人年龄越大,接触致癌物质的几率越高,发生癌变的可能性也就越高。如果一个人在青少年时期受致癌物质的影响较大,那么在步入中年后即有形成恶性肿瘤的可能。同时,中年人免疫系统功能开始衰退,清除癌变细胞的免疫监视机能减弱,为组织癌变提供了条件。目前,除了常规的影像学检查(B超、胸片外),近10种肿瘤标记物的检查,为早期诊断肿瘤创造了条件。如诊断肝癌和前列腺癌的甲胎蛋白和前列腺特异抗原(PSA)等。由于这两种标记物敏感,对诊断相应肿瘤的准确率达80%~90%。

After the age of 40, an anti-cancer health checkup should be conducted every year. People older, the higher the risk of exposure to carcinogens, the higher the possibility of cancer. If a person is greatly affected by carcinogens during adolescence, it is possible to form a malignancy after entering middle age. At the same time, the immune function of middle-aged people began to decline, and the immune surveillance function of eliminating cancerous cells was weakened, which provided the conditions for the canceration of the tissues. Currently, in addition to routine imaging (B ultrasound, chest X-ray), nearly 10 kinds of tumor markers for the early diagnosis of cancer to create the conditions. Such as the diagnosis of liver cancer and prostate cancer alpha-fetoprotein and prostate-specific antigen (PSA). Due to the sensitivity of these two markers, the accuracy of diagnosis of the corresponding tumor is 80% to 90%.
