Uterine cancer primarily affects the lining of the uterus, known as the endometrium, and is the most common female reproductive system cancer in developed countries. It typically presents in women post-menopause, with increasing incidence associated with age. There are several subtypes, including endometrial carcinoma, which is the most prevalent, and uterine sarcomas, which are rarer yet more aggressive. Early detection significantly improves treatment outcomes, making awareness of the condition critical.

Several factors can increase the risk of developing uterine cancer, including obesity, a history of hormone replacement therapy, and irregular menstrual cycles. Additionally, genetic predispositions such as Lynch syndrome can heighten risks, and a personal history of breast or ovarian cancer may also contribute. Women who have never been pregnant and those with certain chronic health conditions like diabetes may also face a higher likelihood of diagnosis.

Common symptoms of uterine cancer include abnormal vaginal bleeding, particularly post-menopausal bleeding, pelvic pain, or discomfort during intercourse. Other indications may manifest as unexplained weight loss or an increase in the frequency of urination. Promptly addressing these symptoms with a healthcare provider is crucial for early identification and intervention.

Uterine cancers, primarily endometrial cancer, are often linked to factors such as obesity, hormonal imbalances, particularly excess estrogen without adequate progesterone, and a history of certain reproductive health issues like polycystic ovary syndrome (PCOS) or endometrial hyperplasia. Other risk factors include age (most common in postmenopausal women), diabetes, hypertension, and a family history of uterine or colon cancer. Lifestyle choices such as poor diet and lack of physical activity may also contribute to the overall risk of developing uterine cancers.

The diagnosis of uterine cancer usually begins with a comprehensive clinical evaluation, including a pelvic examination and a review of medical and family history. Imaging tests such as ultrasound or CT scans may be used, alongside biopsies of the uterine lining to confirm the presence of cancerous cells. Additional diagnostic procedures, such as hysteroscopy, can offer a closer examination and facilitate tissue sampling for accurate diagnosis.

Treatment for uterine cancers typically involves a combination of options including surgery, radiation therapy, and hormone therapy, depending on the stage and type of cancer. Surgical intervention often includes a hysterectomy to remove the uterus, and in some cases, nearby lymph nodes are also removed for further evaluation. For advanced stages, chemotherapy may be recommended to help control the spread of the disease and alleviate symptoms.

While not all cases of uterine cancer can be prevented, certain lifestyle modifications may reduce risk, such as maintaining a healthy weight, engaging in regular physical activity, and managing chronic conditions like hypertension and diabetes. Hormonal treatments for conditions like polycystic ovary syndrome (PCOS) should be discussed with a healthcare provider to prevent endometrial hyperplasia, a precursor to cancer. Regular gynecological check-ups can also aid in early detection and preventative measures.
