    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">近年来，<span style="color: black;">开发</span>出能够检测癌症的血液检测技术，<span style="color: black;">始终</span>是<span style="color: black;">专家</span>聚焦的<span style="color: black;">要紧</span><span style="color: black;">行业</span>。</span></p>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;"><strong style="color: blue;"><span style="color: black;">非常多</span>人的想象是<span style="color: black;">这般</span>的——从人<span style="color: black;">身体</span>取一小瓶血液，<span style="color: black;">经过</span>检测，就能够在癌症<span style="color: black;">初期</span>和最佳治疗<span style="color: black;">周期</span><span style="color: black;">发掘</span>癌症</strong>。</span></p>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">这种想法<span style="color: black;">特别有</span>吸引力，<span style="color: black;">亦</span>是<span style="color: black;">专家</span>们正在积极探索的方向。</span></p>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">但事实证明，尽管付出了很大的<span style="color: black;">奋斗</span>，还是很难找到一种<span style="color: black;">靠谱</span>、准确的血液检测<span style="color: black;">办法</span>来<span style="color: black;">帮忙</span><span style="color: black;">初期</span><span style="color: black;">发掘</span>癌症。</span></p>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">想要在血液中寻找癌症的线索，绝不是容易的事。</span></p>

    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">其次，癌症的标记物在血液中并不是独立存在的，它们与<span style="color: black;">各样</span>健康细胞和其他分子共存于血液中，</span><span style="color: black;"><strong style="color: blue;">仅仅1毫升血液中就有大约50亿个红细胞</strong>。</span></p>

    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">检测结果可能<span style="color: black;">显现</span>假阴性，<span style="color: black;">亦</span><span style="color: black;">便是</span>误判一个癌症<span style="color: black;">病人</span>“<span style="color: black;">无</span>得癌症”；<span style="color: black;">亦</span>可能<span style="color: black;">显现</span>假阳性，误判一个本来<span style="color: black;">无</span>癌症的人“得了癌症”。</span></p>
