Abdominal pain is a common symptom that can be caused by many conditions, including cancer. In cancer, this pain may result from the tumor itself, its spread to other organs, or side effects of treatment.
Cancers that can cause abdominal pain include pancreatic cancer, liver cancer, stomach cancer, colorectal cancer, and ovarian cancer.
Early-stage stomach cancer may cause upper abdomen discomfort, which is usually rated as mild to moderate and described as bloating or a dull pain. Pain can increase in frequency from dull to sharp as cancer develops.
Some women with ovarian cancer may experience pelvic or abdominal pain, bloating, or changes in appetite.
So if you’re experiencing consistent, repetitive or severe abdominal pain — especially if it’s accompanied by weight loss, nausea or difficulty eating — it’s wise to have a healthcare provider assess the situation.
