Cancerous.eu – What is Stomach Cancer? Stomach cancer, also known as gastric cancer, is a type of cancer that starts in the cells lining the stomach. It can develop in any part of the stomach and may spread to other parts of the body.
The exact cause of stomach cancer is not known, but certain factors can increase the risk of developing the disease, including a family history of stomach cancer, smoking, a diet high in salted or smoked foods, infection with the Helicobacter pylori bacteria, and previous stomach surgery.
Symptoms of stomach cancer may include abdominal pain, bloating, nausea, loss of appetite, unintentional weight loss, and vomiting. However, these symptoms may also be caused by other conditions, so it is important to see a doctor for an accurate diagnosis.
Treatment options for stomach cancer may include surgery, chemotherapy, radiation therapy, or a combination of these therapies. The choice of treatment will depend on the stage and location of cancer, as well as the patient’s overall health.
Early detection is important for the successful treatment of stomach cancer, so it is important to see a doctor if you experience any of the symptoms or have any risk factors for the disease.

Type of Stomach Cancer
There are several types of stomach cancer, which are classified based on the type of cells that are involved in the cancer. The most common type of stomach cancer is adenocarcinoma, which starts in the cells that make up the lining of the stomach. Other types of stomach cancer include:
- Lymphoma: This type of cancer starts in the immune system cells that are located in the walls of the stomach.
- Gastrointestinal stromal tumors (GISTs): These are rare tumors that start in the cells that are responsible for the movement of food through the digestive system.
- Carcinoid tumors: These are rare tumors that start in the hormone-producing cells of the stomach.
- Squamous cell carcinoma: This is a rare type of stomach cancer that starts in the cells that line the inside of the stomach.
The treatment and prognosis for each type of stomach cancer may vary depending on the type of cancer, the stage at which it is diagnosed, and the overall health of the patient. It is important to consult with a healthcare professional for an accurate diagnosis and appropriate treatment plan.

Stage of Stomach cancer
Stomach cancer is typically staged based on the size and extent of the tumor, whether it has spread to nearby lymph nodes, and whether it has spread to other parts of the body. The most common staging system for stomach cancer is the TNM system, which stands for tumor, node, and metastasis. The stages of stomach cancer are:
- Stage 0: This stage is also known as carcinoma in situ, which means that the cancer cells are only found in the top layer of cells in the stomach lining.
- Stage I: The cancer has grown into deeper layers of the stomach lining, but has not spread beyond the stomach.
- Stage II: The cancer has grown into nearby lymph nodes or has grown through the outermost layer of the stomach.
- Stage III: The cancer has grown through the stomach wall and into nearby organs or tissues, and may have spread to nearby lymph nodes.
- Stage IV: The cancer has spread to distant organs, such as the liver, lungs, or bones.
The treatment options and prognosis for stomach cancer depend on the stage of the cancer at the time of diagnosis. Early-stage stomach cancer may be treated with surgery to remove the tumor, while advanced-stage cancer may require a combination of surgery, chemotherapy, and radiation therapy. It is important to consult with a healthcare professional for an accurate diagnosis and appropriate treatment plan.

What Are the Symptoms of Stomach Cancer?
The symptoms of stomach cancer can vary from person to person, and some people with early-stage stomach cancer may not experience any symptoms at all. However, some common symptoms of stomach cancer include:
- Abdominal pain or discomfort: This may be felt as a dull ache or a sharp pain in the upper abdomen, and may worsen after eating.
- Bloating or feeling full quickly: This may be caused by the tumor blocking the stomach, making it difficult to eat a normal amount of food.
- Nausea and vomiting: These symptoms may be caused by the tumor irritating the stomach lining, or by the stomach’s inability to digest food properly.
- Loss of appetite: This may be caused by the tumor affecting the stomach’s ability to produce the hormones that regulate hunger.
- Unintentional weight loss: This may be caused by the tumor affecting the body’s ability to absorb nutrients from food.
- Difficulty swallowing: This may be caused by the tumor blocking the esophagus or by the muscles of the stomach becoming weak.
- Fatigue or weakness: These symptoms may be caused by the body’s response to the cancer or by the cancer causing anemia.
It is important to note that these symptoms can also be caused by other conditions, and having one or more of these symptoms does not necessarily mean that a person has stomach cancer. However, if you are experiencing any of these symptoms, especially if they are persistent or worsen over time, it is important to see a doctor for an accurate diagnosis.

What Are the Risk Factors for Stomach Cancer?
Several factors can increase the risk of developing stomach cancer. Some common risk factors include:
- Age: The risk of developing stomach cancer increases as a person gets older, with most cases occurring in people over the age of 50.
- Gender: Stomach cancer is more common in men than in women.
- Family history: People with a family history of stomach cancer are at a higher risk of developing the disease.
- Helicobacter pylori infection: This bacterial infection is a major cause of stomach inflammation and can increase the risk of developing stomach cancer.
- Diet: A diet high in salted, pickled, or smoked foods can increase the risk of developing stomach cancer.
- Smoking: Smoking cigarettes or using other tobacco products increases the risk of developing stomach cancer.
- Alcohol consumption: Heavy alcohol consumption can increase the risk of developing stomach cancer.
- Previous stomach surgery: People who have had surgery to remove part of their stomach are at a higher risk of developing stomach cancer.
- Pernicious anemia: This condition can increase the risk of developing stomach cancer.
It is important to note that having one or more of these risk factors does not necessarily mean that a person will develop stomach cancer, and many people who develop the disease have no known risk factors. However, if you have one or more of these risk factors, it is important to discuss your risk with a healthcare professional and take steps to reduce your risk if possible.

How Is Stomach Cancer Diagnosed?
Stomach cancer is typically diagnosed through a combination of medical history, physical examination, and diagnostic tests. Here are some common methods used to diagnose stomach cancer:
- Medical history and physical examination: Your healthcare provider will ask about your symptoms and any risk factors for stomach cancer. They will also perform a physical exam, including a thorough examination of your abdomen.
- Imaging tests: Imaging tests such as X-rays, CT scans, MRI scans, and ultrasound scans can help your healthcare provider see the inside of your body and look for signs of stomach cancer.
- Endoscopy: In an endoscopy, a thin, flexible tube with a camera on the end is passed through your mouth and down your throat to examine your stomach. If any suspicious areas are found, your healthcare provider may take a tissue sample (biopsy) for further testing.
- Biopsy: A biopsy involves taking a tissue sample from the suspicious area and examining it under a microscope to look for cancer cells.
- Blood tests: Blood tests can help detect certain markers that may indicate the presence of stomach cancer.
