Stomach cancer is the fifth most commonly diagnosed cancer in the world. Over 10 lakh cases of gastric cancer are diagnosed each year around the world. One of the biggest dangers of this disease is the difficulty of diagnosing it. Gastric cancer, like most gastrointestinal cancers, is either asymptomatic in initial stages or the symptoms are mistaken for less serious gastrointestinal issues. Hence, it often goes undiagnosed until after it spreads to other parts of the body.
Once the cancer spreads to other parts of the body, it becomes difficult to cure. This happens often because the cancer wasn't found early enough. Early detection of stomach cancer is key to improving treatment outcomes. So, if we could catch stomach cancers sooner, we might save more lives. But why do these cancers often go undetected until it is too late? Are there warning signs we can look out for?
We speak with Dr. Nikhil Agrawal, Director, Cancer Care, Surgical Oncology, Max Super Speciality Hospital Saket, who answers all your burning questions.
“Mild abdominal discomfort or gastric trouble is usually not a cause for concern. Ignore it if it happens occasionally. But, if symptoms occur regularly, worsen, and don't go away, seek medical help. Don't ignore persistent symptoms,” Dr. Agrawal says, adding that by recognising these symptoms and seeking medical attention promptly, we can catch diseases and cancers early, when they are more treatable.
1. Indigestion, heartburn, and bloating: Most people experience these symptoms occasionally, and it is ok to ignore it. However, persistent symptoms that do not go away could be a sign of something more serious.
2. Vague discomfort or pain in the abdomen: Occasional abdominal pain or discomfort is common and should not be a cause of concern. However, when this is persistent, increasing, and associated with other symptoms, you should seek a medical opinion.
3. Nausea and vomiting: While nausea and vomiting can happen because of various causes such as disagreeable food, recurrent episodes should not be ignored. If you experience these symptoms regularly, particularly if they are accompanied by other signs, it’s important to consult a healthcare professional.
4. Loss of appetite: A sudden and significant decrease in appetite can be a subtle indicator of serious diseases. If you find yourself feeling full after eating only small amounts, this could signal an underlying issue that needs attention.
5. Unexplained weight loss: Unintended weight loss is often alarming and can indicate a serious health concern. If you are losing weight without trying—especially if it occurs alongside other symptoms—it's essential to seek medical advice.
6. Black stool: Black stools indicate bleeding in your gastrointestinal tract. This is usually a serious sign, and you should immediately consult a doctor. Remember that some medicines, such as iron tablets, and some foods can also cause black stools.
7. Low haemoglobin (anaemia): Anaemia can be because of various causes, and stomach cancer is one of them. If you are detected to have low haemoglobin, then get investigated to find the cause.
