There are four symptoms indicating stomach issues:
1. Upper abdominal pain:
In the early stages of stomach cancer, upper abdominal pain is generally not prominent and may be light or imprecise. As the disease progresses, abdominal pain becomes more noticeable and localized.
2. Nausea and vomiting:
Stomach cancer can cause symptoms of nausea and vomiting, especially in cancers located in the gastric antrum. Tumors can block the pylorus over time, preventing the emptying of food.
