Stomach Cancer
What is Stomach Cancer?
Stomach cancer, or gastric cancer, develops from the lining of the stomach. The most prevalent form—adenocarcinoma—is accountable for 90–95% of all cases and develops in the glandular cells that produce mucus and digestive juices. These cancers are also divided into two broad subtypes: intestinal, which tends to form gland-like structures and is often associated with environmental factors; and diffuse, which is more aggressive in character and often associated with genetic mutations.
Stomach Cancer Types
Adenocarcinoma (90–95%)
•Includes intestinal and diffuse types.
Gastrointestinal Stromal Tumors (GISTs)
•Arise from the stomach's connective tissue.
Lymphomas
•Cancers involving the immune system, rarely presenting in the lining of the stomach.
Carcinoid Tumors
•Arise from hormone-secreting cells of the stomach.
Stomach Cancer Symptoms
- •Frequent or long-lasting indigestion or heartburn that does not improve with over-the-counter medications.
What’s Notable
The fifth most common cancer globally
The fourth most common cause of cancer-related deaths globally.
In 2022, there were over 1 million new cases and approximately 770,000 deaths.
When to Seek Help
You should seek medical help if you have persistent symptoms such as ongoing indigestion or heartburn that does not improve, unexplained weight loss, stomach pain or discomfort, difficulty swallowing, vomiting (especially if blood is present), black or tarry stools, or abdominal swelling. If these symptoms last more than two to three weeks or worsen, especially in combination, timely evaluation by a healthcare professional is essential for early diagnosis and effective treatment.
