Colon Cancer Symptoms: Page 4
One bout of upset stomach is nothing to worry about. Ongoing or repeated bouts of cramping, indigestion, nausea, and vomiting, however, are cause for concern.
How it feels: The upset stomach caused by colon cancer can feel like gas, bloating, and aching, or like sharp stabbing cramps and pain that causes you to double over. "I thought I had ulcers" is a common comment of those diagnosed with colon cancer. Some people experience chronic heartburn or acid stomach.
What causes it: An obstruction in the intestines may lead to indigestion, nausea, and vomiting. Inflammation can lead to cramping and pain. When impaired digestion causes food to back up, the result can be acid indigestion.
What to do: Be careful if your doctor diagnoses acid indigestion or heartburn and sends you home with a prescription for heartburn medication. It's fine to take it for a while, but if symptoms persist, return and ask for additional testing.
