<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">癌症难以完全<span style="color: black;">解决</span>，<span style="color: black;">重点</span><span style="color: black;">原由</span>是癌细胞的特性决定的，癌细胞和正常细胞有<span style="color: black;">那些</span>不同？</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">1、癌细胞是一种变异细胞，癌细胞除了分裂<span style="color: black;">失去控制</span>以外，还会侵入<span style="color: black;">周边</span>正常组织，<span style="color: black;">乃至</span>经<span style="color: black;">身体</span>循环系统或淋巴系统转移到的其他部分。 </p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">2、癌细胞能<span style="color: black;">没</span>限增殖，癌细胞间粘着性减弱，易于被凝集素凝集，粘壁性下降。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">3、单个癌细胞的癌细胞核可比正常大1-5倍，核<span style="color: black;">体积</span>不等，容易在<span style="color: black;">身体</span>分散和转移。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">4、细胞癌变<span style="color: black;">出现</span>的一个很<span style="color: black;">要紧</span>的<span style="color: black;">原由</span>是<span style="color: black;">由于</span>细胞基因组<span style="color: black;">出现</span>了突变，继而<span style="color: black;">显现</span>细胞生长和分裂的<span style="color: black;">反常</span>，并将有缺陷的遗传物质传递下去，直至癌组织的<span style="color: black;">显现</span>。</p>
<h2 style="color: black; text-align: left; margin-bottom: 10px;"><span style="color: black;">为何</span>体检难查<span style="color: black;">初期</span>癌症</h2>
<div style="color: black; text-align: left; margin-bottom: 10px;"><img src="https://pic1.zhimg.com/80/v2-e01ba875ed5a445e93f19b770c836eb4_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;"><span style="color: black;">为么</span>健康体检难以<span style="color: black;">初期</span><span style="color: black;">发掘</span>所有癌症？<span style="color: black;">重点</span><span style="color: black;">原由</span>如下：</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">1、<span style="color: black;">初期</span>癌瘤体积微小</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">微小肿瘤<span style="color: black;">通常</span><span style="color: black;">指的是</span>直径<span style="color: black;">少于</span>1厘米，<span style="color: black;">针对</span>身<span style="color: black;">身体</span>位置较深的肿瘤，尤其是体积微小的肿瘤，常规身体<span style="color: black;">检测</span>及影像学<span style="color: black;">检测</span>，难保都能查出。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">仅有</span>当肿瘤长到<span style="color: black;">必定</span><span style="color: black;">体积</span>和密度时，才可能被<span style="color: black;">发掘</span>。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">0.5cm以下的肺部肿瘤，<span style="color: black;">没</span>法<span style="color: black;">经过</span>常规体检和X线胸片和CT<span style="color: black;">检测</span>出来，<span style="color: black;">因此</span><span style="color: black;">大夫</span>常常<span style="color: black;">意见</span><span style="color: black;">跟踪</span>观察。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">2、癌症部位隐匿</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">例如胰腺癌、卵巢癌、纵隔肿瘤等生长部位较隐匿的肿瘤，<span style="color: black;">同期</span><span style="color: black;">无</span><span style="color: black;">显著</span>的症状， 难以<span style="color: black;">经过</span>常规体检<span style="color: black;">初期</span><span style="color: black;">发掘</span>。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">3、癌症恶性<span style="color: black;">行径</span></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">癌细胞鞥浸润转移，健康体检<span style="color: black;">发掘</span>的小肿瘤，并不<span style="color: black;">必定</span>是癌症。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">然则</span>恶性程度很高的癌症，原发病灶很小，就可能已<span style="color: black;">出现</span>了血行播散或淋巴道播散。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">例如肺的小细胞肺癌恶性程度高，病变恶化快，X线胸片<span style="color: black;">发掘</span>肺部小结节，但可能已<span style="color: black;">出现</span>全身广泛转移。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">4、检测<span style="color: black;">办法</span>限制：</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">有些先进的检测可能<span style="color: black;">加强</span>肿瘤检出率，但花费巨大，<span style="color: black;">同期</span>还可能对身体产生潜在的<span style="color: black;">消极</span>影响。PET-CT扫描<span style="color: black;">检测</span>，近年来已<span style="color: black;">作为</span>“时尚”和“高端”<span style="color: black;">检测</span>手段。<span style="color: black;">然则</span>，该手段不仅<span style="color: black;">花费</span>昂贵，<span style="color: black;">况且</span>辐射的潜在影响<span style="color: black;">亦</span>大，<span style="color: black;">通常</span>不<span style="color: black;">做为</span>常规体检的手段。</p>
<h2 style="color: black; text-align: left; margin-bottom: 10px;">应用<span style="color: black;">那些</span><span style="color: black;">检测</span>容易<span style="color: black;">发掘</span><span style="color: black;">初期</span>癌症</h2>

<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">体检是<span style="color: black;">初期</span><span style="color: black;">发掘</span>癌症和癌前病变的<span style="color: black;">要紧</span>途径。体检中各项血液<span style="color: black;">检测</span>指标，<span style="color: black;">彩超</span>、X光、肛门直肠指检，妇科体检中的巴氏涂片、乳腺</p>
