First Signs of Stomach Cancer: What to Watch For

Here are the most common early symptoms that could signal stomach cancer. While these signs may also be caused by less serious issues (like indigestion), it’s important not to ignore them — especially if they persist.

1. Persistent Indigestion or Heartburn

We all get indigestion now and then. But if you're constantly experiencing:

*Burning in the chest or upper stomach

*Acid reflux

*Bloating after eating

it could be more than just a dietary issue. Ongoing discomfort like this may be an early sign of gastric issues, including cancer.

2. Loss of Appetite or Feeling Full Quickly

If you find yourself losing interest in food — or feeling full after just a few bites — it could be a red flag. Tumors in the stomach can restrict its capacity or interfere with digestion, leading to early satiety and weight loss.

3. Unexplained Weight Loss

Losing weight without trying might sound appealing to some, but it’s often a sign that something’s wrong. In stomach cancer, unintentional weight loss can result from reduced appetite, nausea, or the body’s increased energy demands due to the tumor.

4. Stomach Pain or Discomfort

Pain or discomfort in the upper abdomen that:

*Lingers or comes and goes

*Is not clearly related to eating

*Doesn’t respond well to antacids

should be checked out, especially if it becomes more frequent or intense.

5. Nausea and Vomiting

Nausea can stem from many causes — food poisoning, stress, medications — but if it's ongoing and you're also vomiting (sometimes even vomiting blood), it may be an early warning sign of a stomach tumor interfering with digestion.

6. Bloated Feeling After Eating Small Meals

If small portions leave you feeling overly bloated or gassy, it could be more than poor digestion. This sensation, when frequent, could signal something pressing on the stomach or altering the way food is processed.

7. Fatigue and Weakness

As the disease progresses, internal bleeding may occur — often unnoticed at first. Over time, it can lead to anemia, causing:

*Fatigue

*Shortness of breath

*Pale skin

If you’re constantly feeling tired and don’t know why, a blood test and GI evaluation may be needed.

Who’s at Risk for Stomach Cancer?

Anyone can get stomach cancer, but certain factors increase your risk:

*Age (most common in people over 50)

*Helicobacter pylori (H. pylori) infection

*Diets high in smoked or salty foods

*Long-term acid reflux or gastritis

*Family history of stomach cancer

*Smoking and heavy alcohol use

*A history of stomach polyps

When to See a Doctor

If you’re experiencing any combination of the symptoms above, especially if they persist for more than a few weeks, it’s important to speak to a healthcare provider. They may recommend:

*Endoscopy (to look at the stomach lining)

*Biopsy (to test tissue for cancer)

*Imaging tests (like a CT scan or ultrasound)

*Blood tests (to check for anemia or tumor markers)

Conclusion

While early signs of stomach cancer can be subtle or easy to dismiss, listening to your body can save your life. If you're experiencing persistent indigestion, bloating, stomach discomfort, or unexplained weight loss, don't brush it off.

Getting checked early can lead to a faster diagnosis — and more treatment options.
