<div style="color: black; text-align: left; margin-bottom: 10px;"><span style="color: black;">
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">许多人即使<span style="color: black;">已然</span><span style="color: black;">显现</span>了直肠癌的征兆，<span style="color: black;">亦</span>很少有这方面的<span style="color: black;">警觉</span>。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">前些天，我收治了一个直肠癌的<span style="color: black;">青年</span>女性<span style="color: black;">病人</span>，96年的，标准的95后，就非常典型。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">95后<span style="color: black;">女子</span>直肠癌晚期：误以为是痔疮</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">这位95后的<span style="color: black;">女子</span>有痔疮病史5-6年了，常常大便<span style="color: black;">流血</span>，基本都是鲜血，<span style="color: black;">不外</span><span style="color: black;">近期</span>1年半<span style="color: black;">流血</span>量<span style="color: black;">增加</span>。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">这位<span style="color: black;">病人</span>误认为是自己的痔疮加重了。<span style="color: black;">由于</span>工作忙，<span style="color: black;">无</span>时间看<span style="color: black;">大夫</span>，便<span style="color: black;">始终</span>这么拖着。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">近期</span>两个月<span style="color: black;">败兴</span>，她排便越来越困难，大便越来越细，才不得不去看<span style="color: black;">大夫</span>。不看<span style="color: black;">没关系</span>，一看吓一跳：竟然患了直肠癌。</p>

<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">经过</span>简单的直肠指检，<span style="color: black;">发掘</span>直肠肿瘤<span style="color: black;">已然</span>将肠壁全层浸润。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">学医的<span style="color: black;">伴侣</span>都<span style="color: black;">晓得</span>这个常识：病变占据1/4肠壁大约<span style="color: black;">必须</span>6月时间，<span style="color: black;">此刻</span>看来她的病变应该有24月了。</p>
<h2 style="color: black; text-align: left; margin-bottom: 10px;"><span style="color: black;">怎么样</span>分辨直肠癌和痔疮？</h2>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">因为</span>直肠癌非常容易被误诊为痔疮，<span style="color: black;">因此呢</span><span style="color: black;">加强</span>对直肠癌的<span style="color: black;">警觉</span>非常<span style="color: black;">要紧</span>。</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;">怎样</span>区别这两种<span style="color: black;">疾患</span>？下面3种症状<span style="color: black;">能够</span>进行初步判别：</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">其一，<span style="color: black;">流血</span>性质</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">痔疮<span style="color: black;">流血</span><span style="color: black;">常常</span><span style="color: black;">出现</span>于排便时，呈喷射状流出，<span style="color: black;">或</span>在便后滴出鲜血，血与便不相混。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">而直肠癌<span style="color: black;">常常</span>便血相混，并常常伴有脓液和粘液，有特殊的腥臭味，常常有便后</p>
