Early Detection of Uterine Cancer

Uterine cancer is the most common gynecological cancer in the US. Uterine cancer can be broadly classified into two different types, namely endometrial cancer (cancer of the lining of the uterus) and uterine sarcoma (cancer of the muscle of the uterus), with endometrial cancer being the most common type of uterine cancer.

Uterine cancer is a growing cause for concern as incidence and mortality rates have increased each year from 2013 to 2022. However, when detected early, uterine cancer is highly treatable and typically has a favourable prognosis. Notably, the relative five-year survival rate for early stage, localized uterine cancer is approximately 95%. Fortunately, uterine cancer often presents with clear symptoms which enables early detection and timely treatment of the disease. Hence, it is important to understand how uterine cancer can be identified, diagnosed and managed in the early stages.

Early detection refers to the diagnosis of a disease while it is still in the early stages. For uterine cancer, this is when the cancer is still confined within the uterus. Early detection is important as it significantly increases the chances of successful treatment. Early-stage uterine cancer may be treated with surgery alone whereas more aggressive forms of treatment are required in the later stages. Hence, not only does early detection improve treatment outcomes, it also reduces the emotional and physical burden on patients by reducing the need for more aggressive therapies.

Early detection is often carried out through screening tests. Cancer screening tests are used to identify signs of cancer in people who do not exhibit any symptoms. However, they are not usually performed for uterine cancer as there are no accurate and reliable tests available. Hence, it is crucial to understand the symptoms and risk factors associated with uterine cancer to catch the disease as early as possible.

The hallmark sign of uterine cancer is abnormal vaginal bleeding. This includes bleeding after menopause, between periods and heavier or prolonged periods. While not all cases of abnormal vaginal bleeding are due to uterine cancer, any post-menopausal bleeding warrants prompt medical evaluation.

Other common symptoms include abnormal vaginal discharge, pelvic pain and unexplained weight loss. It is important to note that uterine cancer manifests itself differently for each individual. The stage and type of uterine cancer also influence the severity and type of symptoms experienced. Hence, it is crucial to be aware of any unusual changes in your menstrual cycle and seek medical attention immediately if you notice any of these symptoms.

While uterine cancer can affect any woman, certain groups of women have a higher risk of developing the disease. For these groups of women, it is even more crucial to seek medical evaluation should any symptoms develop. These include women who:

• Have undergone menopause and have vaginal bleeding
• Have genetic conditions such as Lynch syndrome
• Have a family history or uterine or colon cancer
• Have had certain breast cancer treatments
• Are obese or have had prolonged estrogen exposure

Additionally, for women with a family history of uterine and/or colon cancers, genetic testing can be performed. This is to identify any mutations in the genes which might indicate an increased likelihood of developing uterine cancer. Regular endometrial biopsies may be recommended for these women to enable early diagnosis of uterine cancer. Hysterectomy may also be an option for women who do not wish to conceive or no longer plan to have children. However, the benefits, risks and limitations of these approaches should be discussed with your healthcare provider to determine if they are appropriate for you.

Early detection of uterine cancer is heavily dependent on recognizing and responding promptly to symptoms rather than formal screening. By being aware of common symptoms and understanding your risks, uterine cancer can be caught early. This improves survival chances substantially as treatment can be delivered at the point at which it is the most effective.
