Helicobacter pylori (H. pylori) infection: This is a long-term infection in the stomach. It causes inflammation of the stomach (Chronic Gastritis) and can lead to cancer over time.
Dietary habits:
Excessive consumption of salty foods, pickles, and dried fish.
Low intake of fruits and vegetables.
Processed meat (for example, sausage, bacon).
Lifestyle:

Excessive alcohol consumption.
Other stomach diseases:
Untreated peptic ulcer.
Polyps (small tumors) in the stomach.
Chronic gastritis.
Genetic factors (Family History): If close relatives in the family have had stomach cancer, this risk may also be genetic.
Age and gender: The risk increases with age (over 50 years). It is more common in men than in women.
Previous surgeries: People who have had previous surgeries for diseases such as stomach ulcers have a slight risk of developing cancer many years later.
