One more symptom of this type of cancer is the abnormal cycle. There are situations when irregular menstrual cycles are a norm. For instance, they are often the consequences of birth control pills and extra stressful situations. In other cases, it is another reason to check the overall health condition. Mind the continuity of the problem: in case an abnormal cycle lasts for 3 or even more months, it is not good at all. Besides, it may be accompanied by the vaginal bleeding, which is not an indicator of the healthy cycle.
