Stomach Cancer: Causes, Symptoms

Stomach cancer, also known as gastric cancer, originates in the lining of the stomach. This disease develops when normal stomach cells undergo genetic mutations, leading to uncontrolled cell growth and the formation of a tumor. While the exact causes of stomach cancer are not fully understood, several risk factors have been identified.

These risk factors include chronic infection with Helicobacter pylori bacteria, a diet high in salty and smoked foods, a family history of stomach cancer, smoking, obesity, and certain genetic conditions. By understanding the potential risk factors and seeking timely medical advice, individuals can take steps to reduce their risk of developing stomach cancer. It is essential to consult with healthcare professionals for personalized guidance and monitoring to maintain stomach health.

What Are the Symptoms of Stomach Cancer

Stomach cancer can present with various symptoms that may include persistent abdominal pain or discomfort. Some patients may also experience fatigue, weakness, or blood in the stool. It's important to consult a healthcare provider if you experience any of these symptoms, as early detection and treatment are crucial for better outcomes.

Persistent nausea, vomiting, and difficulty swallowing may indicate advanced stages of stomach cancer.
Feeling full quickly, even after eating small amounts of food, can be a sign of stomach cancer.
Blood in the stool or black, tarry stools could be indicative of stomach cancer and should be evaluated.
Fatigue, weakness, and a general sense of unwellness may accompany other stomach cancer symptoms.

Causes of Stomach Cancer

Chronic infection with Helicobacter pylori bacteria is a significant risk factor for stomach cancer, as this bacterium can cause inflammation and damage to the stomach lining over time. Other common causes include smoking, a diet high in salty and processed foods, obesity, and a family history of stomach cancer. Additionally, certain genetic factors and long-term stomach inflammation, known as gastritis, can also increase the risk of developing this type of cancer. Making healthy lifestyle choices and addressing risk factors can help lower the likelihood of developing stomach cancer.

Regular consumption of smoked, pickled, or salty foods can increase the likelihood of developing stomach cancer.
Genetic factors, such as a family history of stomach cancer, can predispose individuals to this type of cancer.
Pernicious anemia, a condition where the stomach lacks intrinsic factor, may elevate the risk of stomach cancer.
Long-term inflammation of the stomach lining, known as chronic gastritis, is associated with an increased risk of stomach cancer.

Types Of Stomach Cancer

Stomach cancer has several types, each arising from different types of cells in the stomach lining.Here are the main types

Adenocarcinoma: The most common type of stomach cancer that starts in the glandular cells lining the stomach.
Lymphoma: A cancer that begins in the immune system cells of the stomach.
Gastrointestinal stromal tumors (GISTs): Rare tumors that can develop in the stomach's muscle or connective tissue layers.
Carcinoid tumors: Slow-growing tumors that typically start in the hormone-producing cells of the stomach lining.
Squamous cell carcinoma: A less common type of stomach cancer that originates in the squamous cells lining the stomach's surface.
Small cell carcinoma: A highly aggressive and rare form of stomach cancer that typically spreads quickly.

Risk Factors

Factors such as infection with Helicobacter pylori bacteria, a family history of stomach cancer, smoking, obesity, and a diet high in smoked, pickled, or salty foods can increase the likelihood of developing this type of cancer. Additionally, individuals with certain genetic conditions, chronic gastritis, or a history of stomach polyps may also be at higher risk. It is important to be aware of these risk factors and take proactive steps to maintain a healthy lifestyle to potentially reduce the risk of stomach cancer.

Age over 50: Individuals older than 50 are at higher risk for stomach cancer due to cumulative exposure to risk factors over time.
Helicobacter pylori infection: This common bacterial infection in the stomach is a significant risk factor for developing stomach cancer.
Family history: Having a close relative diagnosed with stomach cancer increases an individual's own risk of developing the disease.
Smoking: Tobacco use, especially long-term smoking, is linked to an increased risk of stomach cancer development.
Diet high in salty and smoked foods: Consuming a diet rich in salt-preserved, smoked, or pickled foods can elevate the risk of stomach cancer.

Diagnosis of Stomach Cancer

They may then order imaging tests such as CT scans or endoscopy to visualize the stomach and obtain tissue samples for biopsy. In more advanced cases, additional tests like laparoscopy or PET scans may be recommended to determine the extent of the cancer's spread. The combination of these diagnostic methods helps healthcare providers accurately identify and stage stomach cancer, guiding them in developing an appropriate treatment plan for the patient.

Endoscopy is commonly used to visualize the stomach lining and take tissue samples for biopsy.
Blood tests may reveal certain markers that can indicate the presence of stomach cancer.
Stool tests can sometimes detect traces of blood that may suggest the presence of stomach cancer.
Biopsy is the definitive method for diagnosing stomach cancer by examining tissue samples under a microscope.

Treatment for Stomach Cancer

Treatment for stomach cancer typically involves a combination of surgery, chemotherapy, and radiation therapy, depending on the stage and location of the tumor. Surgery aims to remove the cancerous tissue and nearby lymph nodes, while chemotherapy and radiation therapy may be used before or after surgery to shrink the tumor or eliminate any remaining cancer cells. Targeted therapy and immunotherapy are also emerging as potential treatment options for stomach cancer.

Surgery is a common treatment for stomach cancer, involving the removal of the tumor and surrounding tissues.
Chemotherapy uses drugs to kill cancer cells and may be recommended before or after surgery to reduce the risk of recurrence.
Radiation therapy uses high-energy beams to destroy cancer cells and is sometimes used alongside surgery or chemotherapy.
Targeted therapy drugs target specific molecules involved in cancer growth and can be used in combination with other treatments.
Immunotherapy boosts the body's immune system to help fight cancer cells and has shown promising results in certain types of stomach cancer.
Palliative care focuses on relieving symptoms and improving quality of life for patients with advanced stomach cancer.
