Stomach cancer typically starts in the mucus-producing cells that line the stomach. This type of cancer is known as adenocarcinoma. For the past many decades, rates of cancer in the central part of the stomach have been falling worldwide. During the same period, cancer disease in the region where the top part of the stomach meets the lower end of the swallowing tube has become much more accessible. This part of the stomach is known as the gastroesophageal junction.
Symptoms of Stomach Cancer
Signs and symptoms of stomach cancer may contain:
1) Fatigue discomfort
2) Feeling bloated after eating
3) Feeling full after eating a small quantity of food
4) Serious, persistent heartburn
5) Chronic indigestion that is always present
6) Unexplained, persistent nausea
7) Stomach pain
8) Persistent vomiting
9) Unintentional weight loss
These are the significant stomach cancer symptoms seen normally in the people
Stomach Cancer Causes
In general, cancer starts when an error happens in a cell’s DNA. The mutation causes the cell to increase and divide at a constant rate and to continue living when a normal cell would die. The combining cancerous cells form a tumor that can invade nearby structures. And cancer cells can break off from the tumor to expand throughout the body. Stomach cancer causes are related to having gastrointestinal reflux disease (GERD) and, less strongly, with obesity and smoking. GERD is a situation caused by a frequent backflow of stomach acid into the esophagus. There is a strong correlation between a diet high in smoked and salted foods and stomach cancer positioned in the central area of the stomach. As the use of refrigeration for preserving foods has increased around the world, the rates of stomach cancer causes have declined.
Diagnosis of Stomach Cancer
Tests and processes used for the diagnosis of gastroesophageal junction cancer and stomach cancer involve
1) Upper Endoscopy: A thin tube including a tiny camera is passed the throat and into the stomach. The doctor can observe signs of cancer. If any suspicious areas are found, a piece of tissue can be collected for analysis.
2) Imaging test: Imaging tests used to watch stomach cancer involve computerized tomography (CT) scans and a particular type of X-ray test, often called a barium swallow.
3) Exploratory Surgery: The doctor may suggest surgery to watch signs that cancer has expanded beyond the esophagus or stomach, within the chest or abdomen. Exploratory surgery is typically performed laparoscopically. This means the surgeon makes many small incisions in the gut and places a special camera that transfers images to a monitor in the operating room.
Stages of Stomach Cancer
The stages of stomach cancer include:
1) Stage I: At this stage, the tumor is restricted to the top layer of tissue that lines the inside of the esophagus or stomach. Cancer cells also may have expanded to a limited number of nearby lymph nodes.
2) Stage II: Cancer at this stage has expanded deeper, increasing into a deeper muscle layer of the esophagus or stomach wall. Cancer may also have developed to more of the lymph nodes.
3) Stage III: At this stage, cancer may have grown through all the layers of the esophagus or stomach and expand to nearby structures. Or it may be a smaller cancer that has developed more extensively to the lymph nodes.
4) Stage IV: This stage indicates that cancer has grown too distant parts of the body.
Stomach Cancer Treatment
The treatment of gastroesophageal junction cancer or stomach cancer based on the stage of cancer, the overall health, and the choices.
2) Radiation Therapy
4) Targeted Medicines
5) Supportive treatment
Prevention of Stomach Cancer
It is not clear what reasons gastroesophageal junction or stomach cancer, so there is no route to prevent stomach cancer. But you can take steps to minimize the chance of gastroesophageal junction cancer and stomach cancer by making small changes to your everyday life. For instance, try to:
1) Exercise: Daily exercise is related to a minimized risk of stomach cancer. Try to fit physical activity into the day time most of the week.
2) Consume more fruits and vegetables: Try to consume more fruits and vegetables into the diet every day. Select a wide variety of colorful fruits and vegetables.
3) Minimize the amount of salty and smoked foods you consume: Protect the stomach by restricting these foods.
4) Quit Smoking: If you do not smoke, do not start. Smoking enhances the chance of stomach cancer and many other types of cancer disease. Quit smoking can be tough, so ask the doctor for help.
5) Consult the doctor about the stomach cancer problem: Consult with the doctor if you have a growing chance of gastroesophageal junction cancer or stomach cancer. Together you may consider periodic endoscopy to watch for symptoms of stomach cancer.
