What Is Stomach Cancer?
The growth of cancerous cells within the stomach lining is called stomach cancer or gastric cancer. This cancer is difficult to analyze because it does not cause any symptoms in the earlier stages. Stomach cancer accounts for 1.7 percent of new cancer cases worldwide.
While stomach cancer is relatively uncommon compared to other types of cancer, probably the biggest threat of this disease is the difficulty of diagnosing it. Since stomach cancer typically does not cause any early symptoms, it often goes undiagnosed until after it spreads to other parts of the body. This makes it more difficult to treat.
Though stomach cancer can be difficult to analyze and treat, it is important to get the learning that individuals have to beat the disease.
What Causes Stomach Cancer?
The stomach is just one part of the upper section of the digestive system. The stomach is liable for digesting food and after that moving the nutrients along to the rest of the digestive organs, in particular the internal organs.
Stomach cancer happens when typically healthy cells within the upper digestive system become cancerous and develop out of control, shaping a tumor. This is a slow process and it takes many years for the tumor to develop.
What Are the Types of Stomach Cancer?
Adenocarcinomas account for 90 to 95 percent of stomach cancer cases. The mucosa, or innermost lining of the stomach, is where these malignancies originate from gland cells.
There are two primary kinds of adenocarcinomas in the stomach:
-
Under a microscope, the cancer cells in intestinal adenocarcinomas appear to be normal cells because they are highly differentiated.
-
Under a microscope, diffuse adenocarcinomas have poorly or undifferentiated cancer cells that appear different from normal cells. Compared to intestinal adenocarcinomas, diffuse adenocarcinomas develop and propagate more quickly and are more difficult to cure.
Other cancers that develop in the stomach are as follows:
-
Gastroesophageal Junction Adenocarcinoma (GEJ) - A cancer that originates at the junction of the esophagus and gastric cardia.
-
Gastrointestinal Neuroendocrine Tumors - A type of cancer that begins in the neuroendocrine cells of the intestinal tract.
-
Gastrointestinal Stromal Tumors (GIST) - A cancer type that begins in the nerve cells that line the wall of the stomach.
-
Primary Gastric Lymphoma - A kind of non-Hodgkin lymphoma that develops in the stomach.
What Are Risk Factors of Stomach Cancer?
Stomach cancer is directly connected to tumors in the stomach. However, there are a few factors that might increase the risk of developing these cancerous cells. These risk factors incorporate certain diseases and conditions, for example,
1. Lymphoma (a type of blood cancer).
2. H.pylori bacterial infection (a common stomach infection that can sometimes prompt ulcers).
3. The presence of tumors in other parts of the digestive system.
4. Stomach polyps (abnormal growth of tissue on the lining of the stomach).
Stomach cancer is more common among:
1. Older adults (as a rule people 50 years and older).
2. Men.
3. Smoking tobacco.
4. A positive family history of the disease.
5. People who are of Asian (particularly Korean or Japanese), South American, or Belarusian descent.
While individuals own medical history can impact their risk of developing stomach cancer, certain lifestyle factors can likewise assume a job. One may probably get stomach cancer if they:
1. Consume a lot of salty and processed foods.
2. Eat too much meat.
3. Have a history of alcohol abuse.
4. Do not exercise.
5. Do not cook or store food properly.
If one is at risk of developing stomach cancer, it is best to get some screening tests done. As this cancer does not cause any symptoms in the early stages, screening tests are the only sure way to rule it out.
What Are the Symptoms of Stomach Cancer?
As indicated by the NCI Trusted Source, there are typically no early signs or symptoms of stomach cancer. Unfortunately, this implies that people often feel nothing is wrong until cancer has reached the late stage. The absolute most common symptoms of cutting edge stomach cancer are:
2. Frequent heartburn.
3. Loss of appetite, sometimes sudden weight loss.
4. Constant bloating.
5. Feeling full after eating a small portion (early satiety).
6. Bloody stools.
7. Jaundice.
8. Excessive fatigue.
9. Stomach pain that worsens after meals.
How Is Stomach Cancer Diagnosed?
To make a diagnosis, the doctor will first play out a physical exam to check for any abnormalities. They may likewise arrange a blood test, including a test for the presence of H. pylori bacteria. More diagnostic tests should be done if the doctor accepts that individual show indications of stomach cancer. Diagnostic tests specifically search for suspected tumors and other abnormalities in the stomach and throat. These tests may include:
1. An upper gastrointestinal endoscopy.
2. Biopsy.
3. Imaging tests, for example, CT scans and X-rays.
How Is Stomach Cancer Treated?
The treatment options include:
1. Chemotherapy.
3. Surgery.
4. Immunotherapy (vaccines and medicines).
The treatment plan will depend on the cause and stage of cancer. Apart from killing the cancer cells in the stomach, the treatment should also prevent the cells from spreading to the lymph nodes, lungs, bones, and liver.
What Are the Ways to Prevent Stomach Cancer?
Stomach cancer as such cannot be prevented, but following tips that can lower the risk of developing all types of cancer.
1) Maintain a healthy weight.
2) Consume a balanced diet and a diet low in fat.
3) Quit smoking.
4) Exercise regularly.
What Is the Prognosis of Stomach Cancer?
When stomach cancer is diagnosed, the prognosis is usually not favorable. As the cancer grows more aggressive and spreads outside of the primary stomach tumor, its overall five-year survival rate decreases. This rate drops to 32 percent if the cancer spreads to the stomach's deeper tissues. The survival rate of stomach cancer decreases to six percent if it has spread to distant organs. Because of this, early detection is essential to improve the prognosis for stomach cancer patients.
Conclusion:
Some medications are also used to lower the risk of stomach cancer. This is generally done for people who have other diseases that may contribute to cancer. To know more about these drugs, consult a medical gastroenterologist online now. The incidence of gastric cancer correlates with socioeconomic status and is clearly dependent on environmental or geographical factors.
