This is a problem that usually occurs only in women, who tend to bloat much more easily than men do. Cancer isn't the only problem that can cause bloating. Indigestion and digestive disorders can cause bloating, and some women even get bloated while on their period. Food sensitivities--like gluten or lactose intolerance--can also be the cause behind the bloating. If, however, the problem persists for more than a week or two, it could be a sign of cancer--particularly if accompanied by bleeding and/or weight loss.

If you have belly or pelvic pain, a reduced appetite, and urinary problems, it could be a sign that you definitely have ovarian cancer. The symptoms will usually occur on a daily basis, and you should be concerned if they last for more than 2 or 3 weeks. You will take a pelvic exam, along with an ultrasound and/or blood tests to locate the problem.
