怎么样发掘初期肠癌？就要靠它们...
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">近年来，我国大肠癌的发病率呈逐年<span style="color: black;">上升</span>的趋势，而能够得到<span style="color: black;">初期</span>确诊的大肠癌<span style="color: black;">病人</span>却很少。在临床上，大肠癌的<span style="color: black;">初期</span>诊断率偏低，其<span style="color: black;">原由</span><span style="color: black;">重点</span>是人们对该病的<span style="color: black;">初期</span>信号<span style="color: black;">无</span>足够的<span style="color: black;">注意</span>。</p>

<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">随着人们健康<span style="color: black;">认识</span>的<span style="color: black;">加强</span>，许多中老年人都会<span style="color: black;">定时</span>做<span style="color: black;">包含</span>血液<span style="color: black;">检测</span>、腹部<span style="color: black;">彩超</span>、胸透等常规体检，可很少有人会主动做肠道健康<span style="color: black;">检测</span>。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">大肠癌是一种可防可治的恶性肿瘤。<span style="color: black;">因为</span>预防<span style="color: black;">办法</span>及健康教育奏效，美国大肠癌发病率与死亡率现<span style="color: black;">处在</span>下降<span style="color: black;">周期</span>；而中国大肠癌发病率与死亡率则<span style="color: black;">处在</span>快速<span style="color: black;">提升</span><span style="color: black;">周期</span>。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">结直肠癌（即大肠癌）的症状较隐匿，在<span style="color: black;">疾患</span>的<span style="color: black;">初期</span>，<span style="color: black;">乃至</span><span style="color: black;">疾患</span>的晚期<span style="color: black;">周期</span>，<span style="color: black;">病人</span>可<span style="color: black;">无</span><span style="color: black;">显著</span>的局部症状，以至于许多<span style="color: black;">病人</span>在确诊时已到中晚期，治疗效果大打折扣。<span style="color: black;">因此呢</span>，肠道的健康<span style="color: black;">检测</span>尤显<span style="color: black;">要紧</span>。</p>

<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">粪便隐血<span style="color: black;">实验</span>、肛门<span style="color: black;">检测</span>指检、肠镜</p>

<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">为何</span>要做隐血<span style="color: black;">实验</span>筛查大肠癌？</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">当消化道少量<span style="color: black;">流血</span>时<span style="color: black;">通常</span>不会有便血、黑便等表现，粪便外观肉眼<span style="color: black;">无</span><span style="color: black;">反常</span>，但<span style="color: black;">经过</span>粪便隐血<span style="color: black;">实验</span><span style="color: black;">能够</span>对消化道内极少量的<span style="color: black;">流血</span>做出判断。</p>

<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">针对</span><span style="color: black;">无</span>胃病病史的人们，<span style="color: black;">倘若</span>体检<span style="color: black;">发掘</span>粪便隐血<span style="color: black;">实验</span>阳性，<span style="color: black;">意见</span>择时再做一次，<span style="color: black;">倘若</span>还是<span style="color: black;">或</span><span style="color: black;">连续</span>呈现阳性<span style="color: black;">那样</span>就<span style="color: black;">必须</span><span style="color: black;">警觉</span>了，<span style="color: black;">首要</span>要排除消化肿瘤，最<span style="color: black;">平常</span>的消化道肿瘤部位有胃、结肠、十二指肠，在专科<span style="color: black;">大夫</span><span style="color: black;">意见</span>下进一步做肠镜或胃镜<span style="color: black;">检测</span>。</p>
