肠癌初期不痛不痒，大便显现4种反常就要警觉！上完厕所记得看一眼
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">说起便血，不<span style="color: black;">晓得</span>你会想到什么呢？</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">可能你会认为与痔疮<span style="color: black;">相关</span>，虽然便血是痔疮的典型症状，<span style="color: black;">然则</span>，它还可能与一种更危险、更可怕的<span style="color: black;">疾患</span><span style="color: black;">相关</span>——肠癌。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">“万病之源，始于肠道。”我国是肠癌的大国，每年有38万人<span style="color: black;">检测</span>出来，19万人因它死亡。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">据统计，临床上有80%以上的肠癌在<span style="color: black;">初期</span>被误以为是痔疮，<span style="color: black;">因此呢</span><span style="color: black;">错失</span>最佳治疗<span style="color: black;">机会</span>，<span style="color: black;">懊悔</span>莫及！</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">肠癌<span style="color: black;">为么</span>难以<span style="color: black;">发掘</span>？</p>
<div style="color: black; text-align: left; margin-bottom: 10px;"><img src="https://pic2.zhimg.com/80/v2-49f6c5258cea9aabcfbdac700e65282d_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;">肠癌近10年来发病率疯狂飙升，增长了97.15%。<span style="color: black;">通常</span>认为高动物蛋白、高脂肪、低纤维<span style="color: black;">膳食</span>是肠癌高发的<span style="color: black;">原因</span>。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">随着生活<span style="color: black;">前提</span>变好，越来越多人从<span style="color: black;">处理</span>温饱到过度<span style="color: black;">膳食</span>，<span style="color: black;">况且</span>人们（尤其是<span style="color: black;">青年</span>人）外出就餐频繁、爱吃红肉（猪、牛、羊肉）、蔬菜<span style="color: black;">果蔬</span>摄入量不足，容易被结肠癌盯上。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">肠癌非常“狡猾”，<span style="color: black;">初期</span>不会<span style="color: black;">显现</span>太多典型症状，常常让人忽略掉；到了晚期，<span style="color: black;">因为</span>病情的恶化，才会有临床的表现。</p>
<div style="color: black; text-align: left; margin-bottom: 10px;"><img src="https://pic3.zhimg.com/80/v2-daaae3f34a70848ee22d9dda90ba03b2_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;">加之，结肠几乎<span style="color: black;">无</span>痛感神经，<span style="color: black;">引起</span>近80%的<span style="color: black;">病人</span><span style="color: black;">发掘</span>时<span style="color: black;">已经是</span>晚期，5年<span style="color: black;">存活</span>率仅有5%至40%，这与<span style="color: black;">初期</span>肠癌95%的<span style="color: black;">存活</span>率比起来，真是天差地别。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">因此呢</span>，早<span style="color: black;">发掘</span>、早诊断、早治疗极其<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;">发掘</span>大便<span style="color: black;">反常</span>，要<span style="color: black;">即时</span><span style="color: black;">看病</span></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">大众</span>千万不要忽视大便，它不仅能反映你的肠道问题，<span style="color: black;">况且</span>还影响全身的健康。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">肠癌来临时，上厕所会<span style="color: black;">显现</span>以下<span style="color: black;">反常</span>，哪怕<span style="color: black;">显现</span>一个，<span style="color: black;">亦</span>要<span style="color: black;">即时</span><span style="color: black;">检测</span>。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">1、便血+黑便</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">正<span style="color: black;">一般人</span>排便时，粪便大<span style="color: black;">都数</span>为黄褐色。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">而患肠癌者，在排便的过程中，会受到粪便的挤压，<span style="color: black;">导致</span>肠道息肉破损<span style="color: black;">显现</span>，再加上有些物质被吸收或因血液中铁离子被氧化，就会<span style="color: black;">显现</span>便血，其粪便呈黑色。</p>
<div style="color: black; text-align: left; margin-bottom: 10px;"><img src="https://pic3.zhimg.com/80/v2-568e0fc4e43768d30c0c8636ac85d842_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;">非常多</span>人以为是痔疮问题，傻傻分不清楚两者的区别：</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">痔疮便血：</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">痔疮<span style="color: black;">显现</span>的便血，多在用力排便时<span style="color: black;">显现</span>，其颜色是鲜红色，<span style="color: black;">一般</span>附在粪便表面，<span style="color: black;">或</span>大便后滴血。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">肠癌便血：</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">而肠癌的便血则是“主动”<span style="color: black;">流血</span>，混杂在大便中，颜色呈暗红<span style="color: black;">或</span>黑色。<span style="color: black;">因为</span>肠道粘膜被破坏，排便时会产生较多的粘膜。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">2、大便性状改变</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">大便性状改变，如原来是成形的，<span style="color: black;">此刻</span><span style="color: black;">显现</span>了黏液便、性状变细条、有固定的压痕等。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">3、便秘或与腹泻交</p>
