What is stomach cancer A Mayo Clinic expert explains
Learn more about stomach cancer from oncologist Mohamad (Bassam) Sonbol, M.D. 请参见副本 供视频使用 What is stomach cancer A Mayo Clinic expert explains I'm Dr. Bassam Sonbol, an oncologist at Mayo Clinic. In this video we'll cover the basics of stomach cancer: What is it? Who gets it? The symptoms, diagnosis, and treatment. Whether you're looking for answers for yourself or someone you love, we're here to give you the best information available. Stomach cancer, also called gastric cancer, can happen in any part of the stomach. However, in the U.S., most stomach cancers occur in the gastroesophageal junction, which is where the esophagus - the tube that carries chewed up food - meets the stomach. There are several different types of stomach cancers, but most are curable if detected at an early stage. What once was the leading cause of cancer death is now well down on the list thanks to the advancement in technology and scientific research. In fact, new cases of stomach cancers have dropped by about 1.5% every year for the last 10 years. Stomach cancer more commonly affects older people. The average age of those diagnosed with stomach cancer is 68. Around 60% of cases occur in patients older than 65, and there is a slightly higher lifetime risk of stomach cancer in men. However, it can affect anyone. Stomach cancer tends to develop slowly over time, usually over many years. What happens is small changes occur in the DNA of the stomach cells, telling them to over multiply and then they accumulate, forming abnormal growth called tumors. There are several known risk factors that could increase your risk of developing stomach cancer, for instance, smoking doubles your risk of stomach cancer, family history of stomach cancer, infection with H. pylori, long-term stomach inflammation, gastroesophageal reflux disease, or stomach polyps. Eating a diet high in salty and smoked foods or low in fruits and vegetables can be also a risk. And there is some correlation between higher weight and risk, as well. Stomach cancer can present itself in several different ways, such as difficulty swallowing, feeling bloated after eating, feeling full after only eating a small amount of food, heartburn, indigestion, nausea, stomach pain, unintentional weight loss, and vomiting. If you have any signs and symptoms that worry you, make an appointment with your doctor. Your doctor may investigate the more common causes of these symptoms first or refer you to a specialist, like a gastroenterologist or an oncologist, like me. To determine if you have stomach cancer, your doctor may start with an upper endoscopy, where a tiny camera is passed through the throat and into the stomach. If your doctor finds something suspicious, they remove some tissue for a biopsy, where the cells gets sent to a lab for further analysis. Your doctor may also run some imaging tests, like CT scan or a special x-ray called a barium swallow. Identifying the extent of the cancer helps your doctor determine the best treatment. To determine the stage, they will run more tests, like blood tests, endoscopic ultrasound, CT scan, or a PET scan. In some cases, your doctor may recommend laparoscopic surgery, where the doctor inserts a special camera directly into the abdomen. Creating a treatment plan for stomach cancer is a collaborative effort between doctors from different specialties. Our goal is to make the best treatment plan for your overall health and personal well-being. There are five main treatment options for stomach cancer: Surgery to remove all of the cancerous tissue and probably some of the healthy tissue around it. Chemotherapy, which uses drugs that journey throughout the body, destroying any cancer cells in its path. Radiation therapy, which uses high-powered beams of energy to target cancer cells. Targeted drug therapy, focusing on blocking specific weaknesses present within cancer cells. And immunotherapy, a drug treatment that helps your immune system recognize which cells are dangerous and attack them. Finding out you have cancer can be really overwhelming and difficult. It can help to find spaces where other people understand what you're going through. Try connecting with cancer survivors online or in your community. Learning about your condition can help you make confident decisions about your care. If you'd like to learn more about stomach cancer, watch our other related videos or visit mayoclinic.org. We wish you well. 胃食管交界处和胃 打开弹出式对话框 关闭 胃食管交界处和胃

胃癌
胃癌最常起源于覆盖胃部内层的细胞。 当胃中的细胞生长异常时就会发生胃癌。胃是腹部中间，肋骨下方的一个肌肉囊。它帮助分解您摄入的食物。 胃癌，也被称为胃肿瘤，可以累及胃的任何部分。在大部分国家，胃癌都发生在胃的主要部分（胃体）。 但是在美国，胃癌更有可能累及运送所吞咽食物的长管（食管）与胃接触的部位。此部位叫做胃食管连接部。 胃癌发生的位置是医生在决定治疗方案时考虑的一个因素。治疗通常包括手术切除胃癌。术前和术后可能会建议其他治疗方法。 产品与服务

胃癌的体征和症状可能包括： 吞咽困难 饭后腹胀 进食少量食物后有饱腹感 胃灼热 消化不良 恶心 胃疼 不经意间的体重减轻 呕吐 何时就诊
如果您对任何体征和症状感到担心，请预约就医。医生首先可能会调查能够引起这些体征和症状的更常见的病因。 申请 Mayo Clinic 预约 病因
目前尚不清楚是何原因导致胃癌，但研究发现，有许多因素都会增加患胃癌的风险。 医生们知道，胃癌始于胃细胞的 DNA 变化。细胞的 DNA 包含指示细胞该如何做的指令。而 DNA 的变化，则会命令胃细胞快速生长，并在健康细胞应该死亡的情况下继续存活。这些不断聚集的细胞形成了可侵入并破坏健康组织的肿瘤。随着时间的推移，这些细胞会分裂并扩散（转移）到身体的其他部位。 风险因素
增加患胃癌风险的因素包括： 胃食管反流病 肥胖症 进食大量咸味和烟熏食物 蔬果摄入不足 胃癌家族史 幽门螺杆菌感染 长期胃发炎（胃炎） 吸烟 胃息肉 预防
为了降低患胃癌的风险，您可以： 保持健康的体重。如果您超重或肥胖，和您的医生讨论帮助减重的策略。目标是一周内使体重缓慢稳定地减轻 0.5 到 0.9 公斤。 选择富含水果和蔬菜的饮食。每天尽量多吃水果和蔬菜。选择各种颜色的水果和蔬菜。 减少咸味和烟熏食品的食用量。通过限制这些食物来保护您的胃。 戒烟。如果您吸烟，请戒烟。如果您不吸烟，继续保持。吸烟会增加您患胃癌和其他癌症的风险。戒烟可能非常困难，因此不妨向医生求助。 向您的医生询问您患胃癌的风险。如果您有较高的胃癌风险，请咨询您的医生。有明显胃癌家族史的人可能考虑做一些检测，比如内镜检查，查找胃癌迹象。 来自妙佑医疗国际员工 在 Mayo Clinic 治疗 申请 Mayo Clinic 预约 诊断与治疗 April 27, 2021 打印 Share on: FacebookTwitterWeChat WeChat
