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.
This is sometimes mistaken for a heart attack, hence the misnomer, heartburn. Gas in the stomach can also cause chest pain when associated with a condition called gastro-esophageal reflux disease (GERD), where stomach contents are washed back up or refluxed into the esophagus. If this happens often, stomach acids may damage the lining of the esophagus, resulting in heartburn.
