Hamilton and colleagues detected significant associations between bloating and increased abdominal distension and diagnosis of ovarian cancer,1 but these symptoms are not early signs of ovarian cancer but of advanced stage disease: an enlarged ovary, omental cake, or ascites. Visiting a doctor will result in diagnosis but not improved prognosis.
Bloating and abdominal distension are non-specific signs. Almost every woman has them in the second half of the menstrual cycle, and women with irritable bowel syndrome experience them frequently if not daily. As most women will not visit their general practitioners for these symptoms, this study cannot be regarded as population based.
Giving prominence to these non-specific signs and referring women to a gynaecologist for ultrasonography is not likely to be cost effective and will increase anxiety about cancer. On the basis of these results, abdominal distension and abdominal pain will yield, respectively, an additional 14 and 217 referrals yearly
