Understanding Uterine Cancer: Symptoms, Risks, and Prevention

Uterine cancer, the sixth most common cancer among women, primarily originates in the uterus, specifically in the endometrium, or lining of the uterus. According to Dr. Vincent Wagner, a Gynecologic Oncologist at the University of Iowa Health Care, this uncontrolled growth of cells can lead to tumor formation. There are two main types of uterine cancer: endometrial cancer, which is the most prevalent and generally treatable when caught early, and uterine sarcoma, which is less common and tends to be more aggressive.

The development of uterine cancer is influenced by various factors. Dr. Wagner notes that most endometrial cancers are linked to prolonged exposure to estrogen, which can stimulate the uterine lining's growth. Key risk factors include obesity, polycystic ovary syndrome (PCOS), early onset of menstruation, late menopause, and hormone therapy without progesterone. Additionally, certain genetic changes are associated with more aggressive subtypes of uterine cancer, which are not as closely tied to hormonal factors. The average age of diagnosis is 60, with postmenopausal women being at a higher risk. Notably, Dr. Jonathan D. Black, a Board-Certified Gynecologic Oncologist, highlights that aggressive types of uterine cancers are more prevalent among Black and Japanese women.

Recognizing the symptoms of uterine cancer is crucial for early detection. The hallmark symptom is abnormal vaginal bleeding, particularly after menopause. Other symptoms include irregular periods, bleeding between periods, pelvic pain, and pelvic pressure. Dr. Wagner emphasizes that some early signs can be easily overlooked, such as pink or watery vaginal discharge, unexplained weight loss, pelvic bloating, and pain during bowel movements or urination.

Experts suggest that women can take proactive steps to reduce their risk of uterine cancer. Dr. Black advises maintaining a healthy weight, as excess body fat can convert into estrogen, increasing cancer risk. Regular exercise is also recommended to improve hormone balance and reduce inflammation. For women experiencing irregular menstrual cycles, hormonal treatments may help protect the uterine lining. Furthermore, being aware of family health history, particularly conditions like Lynch syndrome, can inform screening and preventive strategies.

Both Dr. Wagner and Dr. Black stress the importance of consulting a medical professional for any unusual bleeding, especially postmenopausal bleeding, as early detection significantly improves treatment outcomes. Dr. Wagner notes that when uterine cancer is diagnosed early, it is one of the most treatable cancers.
