Is There a Connection Between Endometriosis and Ovarian Cancer?

Ovarian cancer ranks as the second most common gynecological tumor in developed countries and is the most lethal tumor of the female reproductive system. Despite advancements in radical surgery and chemotherapy, the overall survival rate for ovarian cancer has remained largely unchanged over the past three decades.

Endometriosis is a benign gynecological disease where endometrial tissue is found outside the uterus, causing significant issues like female infertility and dysmenorrhea. The potential link between endometriosis and ovarian cancer has been a subject of research for many years. Some studies indicate that women with endometriosis may have a slightly elevated risk of developing ovarian cancer. But does this mean endometriosis is a precancerous condition?

The Link Between Endometriosis and Ovarian Cancer

Certain studies suggest that women with endometriosis are at a higher risk of developing specific types of ovarian cancer, such as clear cell carcinoma and endometrioid carcinoma. This association could be due to chronic inflammation, hormonal imbalances, and abnormal tissue growth caused by endometriosis. However, the evidence is not definitive enough to classify endometriosis as a direct precursor to ovarian cancer.

Although endometriosis is benign, it exhibits some malignant behaviors such as proliferation, infiltration, metastasis, and recurrence, similar to ovarian cancer. Long-term endometriosis, particularly deep infiltrating endometriosis, might have a potential for malignant transformation. Some studies even suggest that certain treatments for endometriosis, such as the drug danazol, may increase the risk of ovarian cancer.

Misconceptions About Endometriosis and Cancer

Despite these associations, it is incorrect to universally classify endometriosis as a precancerous lesion. Most women with endometriosis do not develop ovarian cancer, and the overall risk of malignancy remains low. Thus, while there is a potential risk, it is not a definitive outcome for all endometriosis patients.

Regular medical monitoring is crucial for women with endometriosis to keep track of any changes in their condition. It is essential to discuss suitable management strategies with healthcare providers to prevent potential complications and maintain good health.

Preventing Pathological Changes in Endometriosis

Here are some steps that can help prevent pathological changes in endometriosis:

1. Avoid Unnecessary Gynecological Examinations: Repetitive or unnecessary gynecological exams, especially near or during menstruation, should be avoided to prevent the endometrium from being squeezed into the fallopian tubes.

2. Quality of Gynecological Surgery: Gynecological surgeries should be performed with care, avoiding times close to menstruation when possible. Gentle procedures and avoiding forceful compression of the uterus can reduce the risk of inducing endometriosis.

3. Operational Norms During Examinations: Doctors should adhere to procedural guidelines during gynecological exams. For instance, hysterosalpingography (HSG) should not be performed immediately after menstruation to minimize the risk of endometriosis.

4. Healthy Lifestyle: Maintaining a balanced diet, engaging in regular moderate exercise, and keeping a healthy weight are crucial. Avoid unhealthy habits like smoking and excessive alcohol consumption.

5. Herbal Medicine and Dietary Adjustments: Herbal medicines, such as Fuyan Pill, combined with dietary adjustments, can improve physical conditions and alleviate symptoms of endometriosis. Always consult a doctor before starting any medication.

6. Regular Check-Ups and Consultations: Regular gynecological exams can help detect and address potential problems early. If symptoms such as pelvic pain or irregular menstruation occur, prompt medical attention and appropriate treatment are necessary.
