Bloating
An early sign of stomach cancer is the feeling bloated or extremely full, especially after each meal. It is caused by the swelling or lump caused by cancerous cells in the digestive tract. However, it can be difficult to diagnose cancer with this condition because this is a very common health issue in many people. The best way to get a precise diagnosis is to seek professional advice from your doctor. Some lab tests would be effective in finding out the underlying cause and ruling out the trigger. [3]
