<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">胃癌是起源于胃黏膜上皮的恶性肿瘤,在我国<span style="color: black;">各样</span>恶性肿瘤中发病率居首位,胃癌发病有<span style="color: black;">显著</span>的地域性差别,在我国的西北与东部沿海地区胃癌发病率比南方地区<span style="color: black;">显著</span>为高。好发年龄在50岁以上,男女发病率之比为2:1。<span style="color: black;">因为</span><span style="color: black;">膳食</span>结构的改变、工作压力增大以及<span style="color: black;"><a style="color: black;">幽门螺杆菌</a></span>的感染等<span style="color: black;">原由</span>,使得胃癌呈现<span style="color: black;">青春</span>化倾向。</p>
