直肠癌的初期症状
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;"><span style="color: black;">直肠癌<span style="color: black;">指的是</span>从齿状线至直肠乙状结肠交界处之间的癌，是消化道最<span style="color: black;">平常</span>的恶性肿瘤之一。直肠癌的<span style="color: black;">初期</span>症状及治疗有<span style="color: black;">那些</span>，得了直肠癌后<span style="color: black;">膳食</span>要<span style="color: black;">重视</span>些什么。</span> </span></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">直肠癌与痔疮区别</span><span style="color: black;"><span style="color: black;">，</span></span><span style="color: black;"><span style="color: black;">直肠癌<span style="color: black;">初期</span>症状与痔疮非常<span style="color: black;">类似</span>。<span style="color: black;">非常多</span><span style="color: black;">病人</span><span style="color: black;">由于</span><span style="color: black;">忽略</span>了这不疼不痒的便血，没能<span style="color: black;">即时</span>确诊。但<span style="color: black;">实质</span>上这两种病还是有区别的。</span> </span></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;"><span style="color: black;">首要</span>，便血不同。痔疮便血的特点是在排便时<span style="color: black;">流血</span>，血色鲜红，排便完后便血<span style="color: black;">自动</span>停止；直肠癌则是大便带血，<span style="color: black;">非常多</span><span style="color: black;">状况</span>下<span style="color: black;">同期</span>混有黏液或脓液，这种血的颜色比痔疮<span style="color: black;">流血</span>颜色要暗<span style="color: black;">有些</span>。其次，直肠癌会<span style="color: black;">显现</span>排便习惯的改变，<span style="color: black;">例如</span>大便变细，次数<span style="color: black;">增加</span>或便秘与</span><span style="color: black;"><span style="color: black;">腹泻交替<span style="color: black;">显现</span>。<span style="color: black;">另外</span>，直肠癌常会伴有其他症状。<span style="color: black;">例如</span>腹部不适、腹胀感或<span style="color: black;">连续</span>性隐痛。<span style="color: black;">因为</span>肿瘤消耗，<span style="color: black;">病人</span>还可能<span style="color: black;">显现</span>贫血、<span style="color: black;">没</span>力、体重减轻、低烧等全身症状。<span style="color: black;">倘若</span>是痔疮，则很少<span style="color: black;">导致</span>这些不适。</span> </span></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">一旦<span style="color: black;">显现</span>便血以及大便功能<span style="color: black;">错乱</span>等可疑症状，不要轻易<span style="color: black;">判断</span>自己是患了痔疮，而应<span style="color: black;">即时</span>找专科<span style="color: black;">大夫</span>就诊，做一下肛门指诊、直肠镜、结肠镜等必要的<span style="color: black;">检测</span>。 </span></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">凡40岁以上有以下任一表现者应列为高危人群：1.一级亲属有结直肠癌史者；2.有癌症史或肠道腺瘤或息肉史；3.大便隐血<span style="color: black;">实验</span>阳性者；4.以下五种表现具两项者：黏液血便、慢性腹泻、</span><span style="color: black;"><span style="color: black;">慢性便秘、慢性阑尾炎史及精神创伤史。</span></span></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;"><span style="color: black;">高危人群更应<span style="color: black;">定时</span><span style="color: black;">检测</span>，<span style="color: black;">警觉</span>肠癌的<span style="color: black;">出现</span>。</span> 直肠癌的<span style="color: black;">初期</span>症状</span><span style="color: black;">1、便血：不少<span style="color: black;">病人</span><span style="color: black;">显现</span>便血都会自以为是小小痔疮<span style="color: black;">导致</span>，不予<span style="color: black;">注意</span>，<span style="color: black;">实质</span>上直肠癌80%都会<span style="color: black;">显现</span>便血<span style="color: black;">状况</span>，严重的会<span style="color: black;">显现</span>粘血便，但因其<span style="color: black;">广泛</span>极易被<span style="color: black;">病人</span><span style="color: black;">忽略</span>。2、黑便：近年来受排毒养颜风潮的影响，不少人<span style="color: black;">乱用</span>泻药从而<span style="color: black;">诱发</span>结肠黑便病<span style="color: black;">明显</span><span style="color: black;">提升</span>，<span style="color: black;">实质</span>上通俗解释<span style="color: black;">便是</span>结肠变黑了，该病伴有腺瘤样息肉和肠癌的比率<span style="color: black;">达到</span>22%-55%。3、腹泻：<span style="color: black;">出现</span><span style="color: black;">连续</span>的大便习惯改变，<span style="color: black;">包含</span><span style="color: black;">忽然</span>便秘、腹泻或两者交替，以及大便次数<span style="color: black;">显著</span><span style="color: black;">增加</span>等都</span><span style="color: black;"><span style="color: black;">是直肠癌部分症状的表现。</span></span></p>
