Stomach (Gastric) Cancer — Causes, Symptoms & Treatment

What is Stomach (Gastric) Cancer?

Stomach cancer, also called gastric cancer, is a disease where cells in the stomach grow out of control. The stomach is an organ in your belly that helps digest food. When cancer starts here, it can spread to other parts of the body if not treated early. According to the World Health Organization (WHO), stomach cancer is one of the most common cancers worldwide. Early detection can make treatment more effective. Therefore, knowing the signs and risks is important for everyone.

Causes of Stomach Cancer

Many factors can increase the risk of stomach cancer. While not everyone with these risks will get cancer, knowing them can help you stay aware. Some common causes include:

Helicobacter pylori infection: This is a type of bacteria that can damage the stomach lining.

Family history: If close relatives had stomach cancer, your risk may be higher.

Smoking: Smoking increases the risk of many cancers, including stomach cancer.

Diet: Eating lots of salty, smoked, or pickled foods can raise your risk.

Age: Most cases happen in people over 50 years old.

Other health conditions: Long-term stomach inflammation or certain types of anemia can also increase risk.

However, having one or more of these factors does not mean you will get stomach cancer. But it is wise to talk to your doctor if you are concerned.

Common Symptoms

Stomach cancer symptoms can be hard to notice at first. Often, they are similar to other common stomach problems. Still, you should see a doctor if you have any of these symptoms for more than a few weeks:

Ongoing stomach pain or discomfort

Feeling full after eating small amounts

Unexplained weight loss

Nausea or vomiting

Loss of appetite

Heartburn or indigestion that does not go away

Blood in stool or vomit (may look dark or black)

Feeling tired or weak

Because these signs can be caused by many things, it is important to get checked. Early diagnosis can improve treatment outcomes.

Diagnosis

Doctors use several tests to find out if someone has stomach cancer. If you have symptoms, your doctor may suggest:

Endoscopy: A thin tube with a camera is passed down your throat to look at your stomach.

Biopsy: During endoscopy, a small tissue sample may be taken for testing.

Imaging tests: Scans like CT or MRI help see if cancer has spread.

Blood tests: These can check for anemia or other problems.

So, if you are wondering how stomach cancer is diagnosed, these are the main steps. Your doctor will explain which tests are best for you.

Treatment Options

Treatment for gastric cancer depends on the stage and your overall health. Your doctor will discuss the best plan for you. Common treatment options include:

Surgery: Removing part or all of the stomach to get rid of cancer.

Chemotherapy: Medicines that kill cancer cells or stop them from growing.

Radiation therapy: High-energy rays used to destroy cancer cells.

Targeted therapy: Drugs that attack specific cancer cells without harming normal cells.

Immunotherapy: Treatments that help your immune system fight cancer.

Sometimes, doctors use more than one treatment. For example, you may have chemotherapy before or after surgery. Each person’s plan is unique, so ask your doctor about your options.

Prevention & Lifestyle Tips

While you cannot prevent all cases of stomach cancer, you can lower your risk. Here are some helpful tips:

Eat more fresh fruits and vegetables

Limit salty, smoked, or pickled foods

Do not smoke or use tobacco

Limit alcohol intake

Maintain a healthy weight

Stay active with regular exercise

Get treated for Helicobacter pylori infection if you have it
