In its early stages, ovarian cancer often has no symptoms. For this reason, nearly 75 percent of women who develop this disease have already progressed past the early stage when they are first diagnosed with ovarian cancer.
Even in its later stages, ovarian cancer may be associated with vague and often ignored symptoms. As the tumor enlarges, the woman may complain of feeling bloated and full and she may noticed that her abdomen seems puffy or swollen. Some women experience nausea, indigestion, gas, loss of appetite and weight loss. Others complain of problems with urination and changes in bowel habits. Less frequently, unexplained vaginal bleeding may occur. Shortness of breath may result if fluid buildup from the abdomen collects near the lungs.
