Stomach cancer usually begins in the mucus-producing cells that line the stomach. This type of cancer is called adenocarcinoma.
Over the past several decades, cancer rates of the main part of the stomach (gastric corpus) have decreased globally. During the same period, cancers in the area where the upper part of the stomach (gastrocardia) meets the lower part of the swallowing tube (esophagus) became more common. This area of the stomach is called the gastroesophageal junction.
Signs and symptoms of gastroesophageal junction cancer and stomach cancer can include:
- Feeling bloated after eating.
- Feeling of fullness after eating small amounts of food.
- Feeling of severe and permanent heartburn in the stomach.
- Severe and permanent indigestion.
- Constant feeling of nausea for no apparent reason.
- Stomach pain.
- Persistent vomiting Unintentional weight loss.
“When do you see a doctor?”
If you have signs and symptoms that worry you, make an appointment with your doctor. Your doctor will likely look at the most common causes of these signs and symptoms first.
In general, cancer begins when an error (mutation) occurs in a cell’s DNA. The mutation causes cells to grow and divide rapidly and continue to live while normal cells would die. The accumulating cancer cells form a tumor that can spread to nearby structures. Cancer cells can break away from the tumor and spread throughout the body.
Gastroesophageal junction cancer is associated with gastroesophageal reflux disease (GERD) and, to a lesser extent, obesity and smoking. Gastroesophageal reflux is a disease caused by the frequent backing up of stomach acid into the esophagus.
There is a strong association between a diet high in salty and smoked foods and stomach cancer, which is located in the main part of the stomach. With the increased use of refrigerators to preserve foods around the world, stomach cancer rates have decreased.
The causes of gastroesophageal junction or stomach cancer are not clear, so there is no way to prevent them, but you can take steps to reduce your risk of developing gastroesophageal junction and stomach cancer by making some simple changes in your daily life. For example, you can try:
exercises. Regular exercise is associated with a lower risk of stomach cancer. Try to get physical activity during the day on most days of the week.
Eat more fruits and vegetables. Try to include more fruits and vegetables in your daily diet. Choose a diet rich in a variety of colorful fruits and vegetables.
Cut back on smoked and salty foods. Protect your stomach from these foods.
- Quit Smoking. If you smoke, quit. If you don’t smoke, don’t start smoking. Smoking increases your risk of stomach cancer as well as other types of cancer. Quitting smoking can be very difficult, so ask your doctor for help.
Ask your doctor about your risk of developing gastroesophageal junction or stomach cancer. Talk to your doctor if you have an increased risk of gastroesophageal junction or stomach cancer. Together, they considered regular endoscopy to look for signs of stomach cancer.
