One of the biggest challenges in detecting stomach cancer is that stomach cancer often develops quietly. In its early stage, the disease may cause few or no noticeable symptoms, and the common signs and symptoms that do appear can easily be mistaken for less serious digestive conditions. As a result, many people are not diagnosed with stomach cancer until additional testing is performed.1

While there is no routine stomach cancer screening program for most people in the United States, physicians may recommend testing for individuals with persistent digestive symptoms or certain risk factors for stomach cancer, such as a family history of stomach cancer or long-term stomach inflammation.

Understanding when to seek medical evaluation, the screening tests for stomach cancer that may be recommended, and how doctors confirm a stomach cancer diagnosis can help patients make informed decisions about their care.1,3

What is Stomach Cancer?

Stomach cancer, also called gastric cancer, is a type of cancer that develops when abnormal cancer cells grow in the lining of the stomach. Most stomach cancer begins in the innermost lining of the stomach before growing into deeper layers of the stomach. As the disease progresses, cancer may spread to nearby tissues or other parts of the body.1

Because stomach cancer often causes few noticeable symptoms in its early stages, many people are not diagnosed with stomach cancer until additional testing is performed. Understanding when testing is recommended, and the diagnostic tools physicians use, can help support an earlier cancer diagnosis ahead of the need for alternative treatments for stomach cancer.

What Are the Early Signs of Stomach Cancer?

One of the reasons stomach cancer can be difficult to detect is that it often causes few noticeable symptoms in its early stages. When symptoms do occur, they are frequently mistaken for common digestive conditions, such as indigestion or acid reflux. Because these changes can seem minor, many people delay seeking medical evaluation.1

Some of the common signs and symptoms that may lead a healthcare provider to recommend further testing include:

  • Loss of appetite
  • Unexplained weight loss
  • Feeling full after eating small amounts of food
  • Persistent bloating after meals
  • Mild or recurring stomach pain or discomfort
  • Nausea or vomiting
  • Heartburn or indigestion
  • Fatigue related to anemia

As stomach cancer progresses, additional symptoms such as vomiting blood, black stools, abdominal swelling, or jaundice may develop. However, these symptoms can also be associated with other digestive conditions and do not necessarily mean you might have stomach cancer. If symptoms persist or worsen, your healthcare provider may recommend a test for stomach cancer to determine the underlying cause.1,3

Can Stomach Cancer Be Detected Early?

Yes, stomach cancer can sometimes be detected early, but it is often difficult because the disease may cause few or no noticeable symptoms during the early stomach cancer stages. As a result, many people are not diagnosed until additional testing is performed.1

There is currently no routine stomach cancer screening program for people at average risk in the United States. However, according to the National Cancer Institute, individuals with certain inherited conditions or other factors that increase the risk of stomach cancer may benefit from closer medical evaluation and screening.3 In countries where stomach cancer tends to be more common, such as Japan and South Korea, regular upper endoscopy is more widely used to help detect stomach cancer at an earlier stage.2,3

Who Should Consider Stomach Cancer Screening?

Although routine gastric cancer screening is not recommended for everyone, some people have a higher risk of developing stomach cancer and may benefit from closer medical monitoring.

Your healthcare provider may recommend screening tests for stomach cancer if you have the following stomach cancer risk factors4:

  • A family history of stomach cancer
  • A history of Helicobacter pylori infection
  • Long-term stomach inflammation (chronic gastritis)
  • Stomach polyps
  • Hereditary diffuse gastric cancer or other inherited cancer syndromes
  • Lynch syndrome (hereditary nonpolyposis colorectal cancer)
  • Previous surgery in which part of the stomach was removed requires ongoing surveillance
  • Other conditions associated with an increased risk of stomach cancer

If you have one or more of these risk factors, your healthcare provider can determine whether additional monitoring or testing is appropriate based on your medical history and overall health.3

How Is Stomach Cancer Diagnosed?

There is no single test for stomach cancer. Instead, physicians use a combination of examinations, laboratory testing, endoscopic procedures, and imaging studies to confirm a stomach cancer diagnosis and determine whether the disease has progressed beyond the stomach.

The goal of diagnostic testing is not only to find cancer, but also to identify the stage of the disease, determine the type of stomach cancer, and evaluate whether cancer spreads to nearby lymph nodes or other organs.

Medical History and Physical Examination

Diagnosis usually begins with a discussion about your symptoms, personal medical history, family history of stomach cancer, and other risk factors for stomach cancer. Your physician will also perform a physical examination and determine whether additional testing is needed.3,5

Upper Endoscopy

The most common test for stomach cancer, an upper endoscopy, involves looking at your stomach through a thin, flexible tube called an endoscope. The endoscope features a camera at its tip.

This is inserted down your throat (usually while you are under sedation). With the endoscope, your doctor can see the inside of your esophagus, stomach, and beginning section of the small intestine. If abnormal tissue is found, small tissue samples can often be collected during the same procedure for additional testing.1,5

If the growths are small enough, the doctor can actually remove them entirely with the endoscope. An upper endoscopy may also be used to relieve complications caused by stomach cancer diagnosis. However, upper endoscopies can potentially miss some types of stomach cancer. In these cases, your doctor may use other imaging tests.

Biopsy

If your doctor identifies an abnormal growth or suspicious tissue during an endoscopy, a biopsy is typically the next step in confirming a stomach cancer diagnosis. A biopsy involves removing a small sample of tissue and sending it to a laboratory, where a pathologist examines it for cancer cells.1

Depending on the findings, your doctor may also collect biopsy samples from nearby areas, such as the lymph nodes, to determine whether cancer spreads beyond the stomach. If the abnormal tissue is located deeper within the stomach wall, an endoscopic ultrasound may be used to guide a thin, hollow needle into the tissue to collect the sample.3,5

A biopsy is the most reliable test for stomach cancer because it can confirm whether cancer is present and help identify the type of stomach cancer. These results are used alongside imaging tests to determine the stage of the disease and guide treatment planning.1

Endoscopic Ultrasound

If an upper endoscopy does not provide enough information, your doctor may recommend an endoscopic ultrasound (EUS) to evaluate areas that cannot be seen clearly during a standard endoscopy. This test is particularly useful for helping physicians detect stomach cancer that has grown deeper into the stomach wall and determine whether cancer spreads to nearby lymph nodes.5

Like a standard endoscopy, an endoscopic ultrasound uses a thin, flexible tube that is passed into the stomach. However, the endoscope is fitted with a small ultrasound probe that uses sound waves to create detailed images of your stomach and the surrounding tissues.

An endoscopic ultrasound may help physicians:

  • Evaluate how deeply the tumor has grown through the layers of the stomach
  • Examine nearby lymph nodes for signs that cancer may have spread
  • Guide a needle biopsy if tissue samples are needed from deeper areas of the stomach wall

The additional information provided by an endoscopic ultrasound helps physicians determine the stage of the disease and develop an individualized treatment plan.3,5

CT, PET, and MRI Scans

If stomach cancer is confirmed, imaging studies provide additional information about the disease.

Depending on your situation, your physician may recommend:

  • CT scans to evaluate the abdomen and surrounding organs
  • PET scans to help identify whether cancer spreads beyond the stomach
  • MRI scans to provide detailed images when additional evaluation is needed

These tests help determine the stage of the disease and provide important information for developing an individualized treatment plan.3,5

What Happens After a Stomach Cancer Diagnosis?

Receiving a stomach cancer diagnosis is the beginning of developing a personalized treatment plan.

After diagnostic testing is complete, physicians evaluate several important factors, including:

  • The stage of the cancer
  • The location and size of the tumor
  • Whether nearby lymph nodes are involved
  • Whether cancer spreads beyond the stomach
  • Your overall health and medical history

Understanding these findings helps physicians recommend the most appropriate cancer treatment and discuss available treatments for stomach cancer based on your individual diagnosis and goals.

The success of how to treat stomach cancer depends on a lot of things, but as with most cancers, the prognosis is better when the cancer is caught at an earlier stage.

Alternative Treatment Options for Stomach Cancer

After a stomach cancer diagnosis, many patients begin exploring different approaches to cancer treatment. At ITC, our physicians develop individualized treatment programs that focus on addressing stomach cancer while supporting the body’s natural healing processes.

ITC offers alternative treatments and natural pain relief for stomach cancer through personalized care plans designed around each patient’s diagnosis, stage of disease, and overall health. Depending on your needs, your physician may recommend a combination of evidence-informed therapies that support whole-person wellness while addressing the disease using non-invasive or minimally invasive approaches.

Personalized Alternative Therapies at ITC

Following a comprehensive evaluation, your physician may recommend one or more stomach cancer treatments based on your individual diagnosis.

Intratumoral Immunotherapy

Intratumoral immunotherapy delivers immune-based medications directly into the tumor rather than through systemic administration. By targeting treatment directly to the tumor site, this approach aims to destroy cancer cells while limiting unnecessary exposure to surrounding healthy tissue.

Localized Hyperthermia

Localized hyperthermia cancer treatment is based on research that supports using high temperatures of 113 degrees to heat body tissue, subsequently killing cancer cells without injuring healthy tissue. Often combined with other types of treatment, localized hyperthermia targets a cancer cell’s proteins and other structures, resulting in smaller tumors.

Laser Cancer Therapy

Light Amplification by Stimulated Emission of Radiation uses a strong light beam to precisely target and penetrate cancerous tissue, effectively destroying it with minimal effects on the surrounding tissue. The following laser cancer treatment options also result in a less painful recovery.

These may include:

  • Carbon Dioxide (CO₂) Lasers – Used to target abnormal tissue located near the surface, including selected early-stage cancers
  • Argon Lasers – Often used with photodynamic therapy, argon lasers seal blood vessels during radiation therapy and help prevent bleeding
  • Nd:YAG Lasers – Generate heat energy capable of reaching deeper tissue and may help kill cancer cells in localized areas

The type of laser selected depends on the tumor’s location and the patient’s individualized treatment plan.

Gerson Therapy

Nutrition is an important part of whole-person cancer care. ITC incorporates the principles of Gerson Therapy through individualized nutritional guidance emphasizing organic, plant-based foods, physician-selected supplements, and detoxification practices. Through Gerson Therapy cancer treatment, we develop a three-component regimen.

  • Vegetarian diet
  • Daily supplements
  • Detoxification

The goal is to help support immune function, promote overall wellness, and provide nutritional support throughout treatment.

DMSO Potentiation Therapy

With a DMSO dosage tailored to meet your health and personal needs, DPT works with other drugs that treat cancer by helping them to penetrate the cancer cells, and subsequently, requiring a lower dosage of medication.

Because the DMSO bypasses the digestive tract and acids, the medication is more effectively absorbed into the system. An added benefit of DMSO IV therapy for cancer treatment is that it allows the individual to receive healing nutrients even while unable to eat.

Psycho-Spiritual Therapy

A stomach cancer diagnosis can affect emotional, mental, and spiritual well-being in addition to physical health.

Psycho-spiritual therapy supports patients by encouraging emotional resilience, stress management, and a stronger mind-body connection throughout their healing journey. This therapy reflects ITC’s holistic philosophy of treating the whole person rather than focusing solely on the disease.

Natural Halotherapy

Also known as biophotonic therapy, natural halo light therapy combines botanical compounds with controlled light exposure as part of ITC’s holistic approach to wellness.

This therapy is designed to support healthy cellular function, encourage tissue health, and promote overall well-being as part of an individualized treatment program.

Vitamin and Mineral Supplementation

One of the key components for combating cancer is maintaining a healthy immune system. While killing damaged cells, cancer treatments also have a supplemental effect of reducing appetite, leaving patients with a nutrient deficiency and a reduced ability to combat the greater risk of illness. may be administered by taking a daily tablet orally, intravenously, or by injection.

After reviewing laboratory findings and nutritional status, ITC physicians may recommend personalized vitamin and mineral supplements to help address deficiencies, support immune function, and promote overall wellness during treatment.
