Will menstruation be normal in cervical cancer? Most of the early stages of cervical cancer do not have typical clinical symptoms and may not affect menstruation, which may be normal. Only when cervical cancer occurs to a certain stage or exophytic type of cervical cancer, vaginal bleeding may occur, and invasion of blood vessels may lead to increased menstruation or delayed menstruation. Usually it is in the middle and advanced stages of cervical cancer that menstruation may be affected because it invades blood vessels, especially the heavy bleeding caused by invasion of large blood vessels, which may lead to postponement of menstruation or even heavy menstruation. Therefore, we should not rely on normal menstruation to determine whether we have cervical cancer or not. We should have regular cervical cancer screening and hpv testing every year, which are very effective measures to prevent cervical cancer.
