Flatulence, or gas, is actually a normal bodily function and, in fact, it is quite healthy. Flatulence is the by-product of digestion, although when cancer treatment causes severe flatulence and/or lower abdominal pain, measures can be taken to minimize the treatment's effects.
Fortunately, stomach cancers are a very rare cause of gas and bloating; however, it does happen. This is caused by a tumor developing inside the stomach, causing problems such as bloating, gas, a feeling of fullness or discomfort. A hard stomach might also be one of the symptoms of stomach cancer.
