The full explanation.
The simple version
Belly pain is one of the most common symptoms there is, and it is very rarely caused by cancer. Most abdominal pain comes from everyday digestive causes and settles quickly.
What usually causes belly pain
Common causes include indigestion, gas and bloating, constipation, stomach bugs, food intolerances, irritable bowel syndrome, period pain, and urinary infections. These are common, come and go, and often relate to eating, bowel habits, or the menstrual cycle.
When belly pain is more worth checking
Pain is more worth a doctor's look when it is persistent or steadily worsening, wakes you at night, or comes with other symptoms such as unexplained weight loss, a change in bowel habits, feeling full quickly, blood in the stool, or yellowing of the skin. These have many non-cancer causes too but are worth reviewing.
When to see a doctor
See a doctor for belly pain that lasts more than a couple of weeks, keeps worsening, or comes with weight loss, bowel changes, or other symptoms. Sudden, severe pain should be checked urgently. Most belly pain has a harmless, treatable cause.
