Naturally, individual cases dictate which tests and treatments are best, but an additional concern about frequent screenings is the problem of false positives. When one is looking for something relatively rare (whether cancer or terrorists), it is wise to remember that a positive result is often false.
毫无疑问，适用于不同病例的检测和治疗方案各有不同，但对于频繁的筛查来说，另一个要注意的地方就是假阳性的问题。当您在寻找一项相对罕见的东西之时（不管是癌症还是恐怖分子），最好记住某些阳性结论往往会是错误的。要么那个“检测出来的”病理状态根本不存在，要么就并不是致命的。
