Key Risk Factors You Should Know
Long-term inflammation of the stomach lining, known as chronic gastritis, can increase the risk of stomach cancer. While inflammation is a normal immune response, chronic irritation can damage stomach cells and trigger DNA changes, making them more vulnerable to malignancy .
Pernicious anemia, a condition linked to chronic gastritis, occurs when the body fails to absorb enough vitamin B12. Over time, this deficiency can cause further stomach lining damage, increasing cancer risk. Pernicious anemia is often autoimmune-related, meaning the immune system mistakenly attacks stomach cells that produce intrinsic factor, worsening inflammation.
Because both chronic gastritis and pernicious anemia involve stomach lining damage, individuals with these conditions should consult their doctor about regular screenings to monitor for potential cancerous changes.
