It produces a total blood loss of 30 to 80 mL (about 2 to 8 tablespoons), and occurs normally every 21 to 35 days.</p><p>Vaginal bleeding that occurs between periods or after menopause can be caused by various problems. Most are benign and can be easily treated. Sometimes, vaginal bleeding may be due to cancer or pre-cancer. Therefore, any unusual bleeding should be evaluated right away. The risk for cancer increases to about 10% in women with postmenopausal bleeding.</p><p>Make sure that bleeding is coming from the <a test="test" href="./002342.htm">vagina</a> and is not from the rectum or the urine. Inserting a tampon into the vagina will confirm the vagina, cervix, or uterus as the source of bleeding.</p><p>A careful exam by your health care provider is most often the best way to find the source of the bleeding. This exam can be done even while you are bleeding.</p></div></div></section><section><div class="section"><div class="section-header"><div class="section-title"><h2>Causes</h2></div><div class="section-button"><button type="submit" aria-controls="section-2" role="button" title="Expand/Collapse section"><span class="icon icon-section-action">
