Frequently Asked Questions
Why is stomach cancer often diagnosed late?
It often grows slowly over many years and may not cause noticeable symptoms until an advanced stage, with early symptoms like indigestion or feeling full quickly often mistaken for less serious digestive issues. This is why persistent digestive symptoms, especially in someone with risk factors, deserve prompt medical evaluation rather than being dismissed.
Does H. pylori infection really cause stomach cancer?
Yes, chronic infection with Helicobacter pylori bacteria causes long-term inflammation of the stomach lining that can lead to malignant changes over time, making it the single most significant identifiable risk factor. Testing and treating H. pylori infection when found is an important preventive step, particularly for those with a family history of stomach cancer.
Is stomach cancer more common in certain regions?
Yes, its incidence varies considerably by region, being notably higher in parts of East Asia, likely reflecting a combination of H. pylori prevalence and traditional dietary patterns high in smoked, salted, or pickled foods common in those regions. It is less common in India than in East Asia, though risk factors like H. pylori infection are still relevant locally.
Can stomach cancer be treated successfully?
Localized disease is often treated successfully with surgical removal of part or all of the stomach, sometimes combined with chemotherapy, while more advanced or metastatic cases have more limited but still meaningful treatment options including targeted therapy and immunotherapy. Outcomes are generally better the earlier the cancer is caught, reinforcing the value of prompt evaluation of persistent symptoms.
What dietary changes help reduce stomach cancer risk?
Reducing intake of smoked and salted foods while increasing fruit and vegetable consumption are recommended preventive measures, alongside not smoking and treating any H. pylori infection. These changes are especially relevant for people with a family history of stomach cancer or chronic gastritis.
