Since uterine cancer affects the uterus, every woman is at risk for contracting this type of cancer (unless you’ve had a hysterectomy). However it is most common for women over the age of 50 who have gone through menopause.  One major risk factor for developing uterine cancer is taking hormones or other drugs. These hormone risks include using estrogen without also using progesterone, or taking Tamoxifen – a drug used to treat certain forms of breast cancer. There are also certain physical factors that can contribute to an increased risk of contracting uterine cancer. Major bodily factors include being obese, being a smoker, or having a history of uterine, colon, or ovarian cancer in your family. You are also a greater risk if you have had problems getting pregnant or if you had fewer than five periods a year before beginning menopause. Another risk factor is suffering from endometrial hyperplasia. Abnormal bleeding or postmenopausal bleeding is the most common early symptom of endometrial cancer. If you notice any vaginal bleeding that is not normal for you and your monthly cycle, you should be mindful of your symptoms so that you can recall them for your doctor.  If the abnormal bleeding continues for any considerable amount of time (more than a few days) or if it happens during several monthly cycles in a row, consider notifying your doctor. Check for bleeding between periods. If you notice bleeding between periods, this can be a symptom of uterine cancer.  Be wary of bleeding that last longer or is heavier than normal. If your menstrual cycle changes in any way, this can be a symptom of a problem with your reproductive system, including uterine cancer. Look for changes like heavier periods than normal, longer periods than normal, or increased PMS symptoms (cramps, fatigue, etc.). Keep a journal recording these occurrences. Bleeding, even a small amount (also known as spotting), after having gone through menopause can be problematic for many reasons. One of these reasons is the possibility of uterine cancer. If you are vaginally bleeding after menopause, you should consult your doctor immediately. Since menopause eliminates your body’s need to go through the menstrual cycle every month, any bleeding after menopause can be problematic and should be taken seriously. Take the time to notice if your menstrual periods last longer than seven days. A longer than average menstrual cycle can be indicative of problems with your reproductive system, including uterine cancer. Keep track of how many days your period lasts for several cycles in a row so you can tell your doctor. A doctor can help you regulate your periods so that they are more manageable and make sure there are no underlying problems causing the longer periods.

Summary:
Know the risk factors. Notice if you have abnormal vaginal bleeding. Watch for bleeding after menopause. Track your cycle.
