宫颈癌的核心诱因是HPV（人乳头瘤病毒）感染，但从感染到最终确诊宫颈癌并非一蹴而就，而是需经历明确的渐进式病变过程：首先是宫颈低级别鳞状上皮内病变（LSIL，即CIN1），随后进展为宫颈高级别鳞状上皮内病变（HSIL，含中度CIN2与重度CIN3）。临床数据显示，从HPV感染发展为宫颈癌前病变通常需要5年左右；而从癌前病变进一步恶化为浸润癌，周期可长达10至20年。

Somehow it worked out.
The NCAR team spent the next ten years working on the problem with researchers at airlines, universities, the F.A.A., NASA, and NOAA—the National Oceanic and Atmospheric Administration. “It was a national imperative,” Cornman said. Luckily, the beginnings of a solution were already in place. The team at NCAR had used sophisticated new Doppler radar systems to detect microbursts. When those were added to the wind detectors already installed at many airports, and the two systems were integrated with software that Cornman developed, microbursts could be detected as they were happening. “A problem where hundreds of people were dying suddenly stopped,” Cornman said. The last time a commercial flight was downed by a microburst in the U.S. was in 1994.
