According to the NCI, stomach cancer is asymptomatic and this implies that it often goes undetected until an advanced stage. Some of the most common symptoms of stomach cancer are:
- Nausea
- Unexplained heartburn
- Constant bloating
- Poor appetite
- Blood in the stool
- Jaundice
- Feeling full after eating in small portions
- Excessive fatigue and exhaustion
- Stomach ache
- Low red blood cell count (anemia)
- Swelling and fluid build up
There is a high probability that these symptoms are caused by things other than cancer like viruses or ulcers. But experiencing these symptoms chronically is an indication to get oneself examined by a doctor. Read more on the different stomach cancer types.
