癌症抽血能查出来吗？
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"> 癌症抽血能查出来吗？<span style="color: black;">首要</span>，<span style="color: black;">检测</span>血液<span style="color: black;">能够</span>查出<span style="color: black;">是不是</span>患上了癌症，<span style="color: black;">然则</span><span style="color: black;">都数</span><span style="color: black;">状况</span>下，<span style="color: black;">检测</span>血液只是癌症筛查的手段的一个环节，它还<span style="color: black;">必须</span>别的手段来对癌症进行确诊。</p>

<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">那样</span>，<span style="color: black;">咱们</span>说的<span style="color: black;">检测</span>血液，<span style="color: black;">详细</span><span style="color: black;">检测</span>的是什么呢？在癌症筛查中，<span style="color: black;">检测</span>血液<span style="color: black;">重点</span>是<span style="color: black;">检测</span>肿瘤标志物，临床中除了<span style="color: black;">少许</span>癌症，如白血病，<span style="color: black;">因为</span>血液中就带有癌症信息，<span style="color: black;">因此</span><span style="color: black;">能够</span>通过验血直接<span style="color: black;">发掘</span>白血病；而其他绝大<span style="color: black;">都数</span>的肿瘤，只能<span style="color: black;">经过</span>血液中肿瘤标志物的指标来做初步的判断，当肿瘤标志物反映出癌症的倾向时，<span style="color: black;">经过</span>后续的设备<span style="color: black;">检测</span>来确诊肿瘤的部位、性质和<span style="color: black;">体积</span>。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"> 什么是肿瘤标志物？</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">肿瘤标志物是<span style="color: black;">有些</span>能反映肿瘤<span style="color: black;">是不是</span>存在的化学类物质，<span style="color: black;">经过</span>这些标志物<span style="color: black;">是不是</span>存在或数量的变化，<span style="color: black;">能够</span><span style="color: black;">认识</span>癌细胞的组织分化和细胞功能，为癌症的诊断和<span style="color: black;">归类</span><span style="color: black;">供给</span>依据。</p>
<div style="color: black; text-align: left; margin-bottom: 10px;"><img src="https://pic4.zhimg.com/80/v2-1cc54f8a83191022caf1c7cb402a6af3_720w.webp" style="width: 50%; margin-bottom: 20px;"></div>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">例如：癌抗原15-3这是乳腺癌的辅助诊断标志，<span style="color: black;">咱们</span><span style="color: black;">一般人</span>的血清中，癌抗原15-3含量，每毫升<span style="color: black;">少于</span>30国际单位，<span style="color: black;">倘若</span>这个指标高，<span style="color: black;">那样</span>乳腺癌的患病概率就相对<span style="color: black;">很强</span>，<span style="color: black;">另外</span>癌抗原15-3指标<span style="color: black;">上升</span>，<span style="color: black;">亦</span>是判断结肠癌、宫颈癌、原发性肝癌、肺癌、肠癌和胰腺癌等癌症的参考指标；大部分的卵巢癌<span style="color: black;">病人</span>血清中癌抗原125水平会<span style="color: black;">上升</span>；肠癌、肝胆癌、胃癌和胰腺癌<span style="color: black;">病人</span>血清中糖链抗原19-9会<span style="color: black;">显著</span><span style="color: black;">上升</span>；甲胎蛋白是<span style="color: black;">帮助</span>诊断肝癌的<span style="color: black;">要紧</span>指标，<span style="color: black;">经过</span>它<span style="color: black;">能够</span>初步判断<span style="color: black;">初期</span>原发性肝癌。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"> 肿瘤标志物指标正常应该就不是癌症了吧？</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">肿瘤标志物是判断肿瘤的依据，但不是<span style="color: black;">独一</span>的依据，它<span style="color: black;">必须</span>结合其他手段<span style="color: black;">才可</span>对癌症进行确诊，<span style="color: black;">咱们</span>可以把它理解成交通信号灯的黄色灯，起到警示的<span style="color: black;">功效</span>，当肿瘤标志物指标高了，<span style="color: black;">咱们</span>就应该留意是不是患上了某种肿瘤，经过后续的<span style="color: black;">检测</span>得出<span style="color: black;">最后</span>的判断，<span style="color: black;">倘若</span>肿瘤标志物<span style="color: black;">检测</span>正常，<span style="color: black;">亦</span>不<span style="color: black;">表率</span><span style="color: black;">无</span>肿瘤，临床中<span style="color: black;">亦</span>有恶性肿瘤<span style="color: black;">已然</span>很大了，但肿瘤标志物并<span style="color: black;">无</span><span style="color: black;">上升</span>迹象。随着科技的进步，尤其是DNA和RNA<span style="color: black;">科研</span>成果的应用、新诊断指标的<span style="color: black;">显现</span>、肿瘤标志物诊断策略的<span style="color: black;">提高</span>，在不远的将来，肿瘤标志物对癌症判断的准确性<span style="color: black;">亦</span>将大幅<span style="color: black;">提高</span>。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"> <span style="color: black;">检测</span>肿瘤的手段</p>

<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">肿瘤标志物是血液<span style="color: black;">检测</span>项目中的一类指标，虽然它既<span style="color: black;">不可</span>反映病灶所在位置，<span style="color: black;">亦</span><span style="color: black;">不可</span>用以<span style="color: black;">判断</span>肿瘤存在与否，但对<span style="color: black;">大夫</span>而言，它有指向和参考的<span style="color: black;">功效</span>，它<span style="color: black;">一般</span>是结合CT、核磁、<span style="color: black;">彩超</span>的<span style="color: black;">检测</span>来做判断，<span style="color: black;">仅有</span><span style="color: black;">发掘</span>了占位性病变，再经过病理学上的确认，<span style="color: black;">才可</span><span style="color: black;">最后</span>判断<span style="color: black;">是不是</span>有肿瘤以及肿瘤的性质、部位和<span style="color: black;">体积</span>等；有些<span style="color: black;">病人</span><span style="color: black;">显现</span>不适症状后，不经抽血直接<span style="color: black;">经过</span>CT、<span style="color: black;">彩超</span>等途径<span style="color: black;">亦</span><span style="color: black;">能够</span>直接<span style="color: black;">检测</span>出<span style="color: black;">是不是</span>有肿瘤，<span style="color: black;">选取</span>哪一种<span style="color: black;">检测</span>方式可视<span style="color: black;">详细</span><span style="color: black;">状况</span>而定。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"> 最后，癌症不可怕，只要读者有早筛的<span style="color: black;">认识</span>，癌症的预防就很容易。</p>
