What is the cause of the mass in the pelvis?

Pelvic masses may be caused by physiological reasons such as corpus luteum cysts during female ovulation, infectious diseases such as pelvic inflammatory abscess, benign lesions such as myomas, ovarian cysts or malignant tumors, etc. It is necessary to seek medical attention as soon as possible for a clear diagnosis, and carry out targeted treatment after the diagnosis is confirmed through imaging examinations and pathological tests.

1Genetic and physiological factors

Certain congenital diseases may cause a mass to form in the pelvis, such as an ovarian cyst or an ovarian uterine malformation. Normal physiological changes may also cause symptoms similar to a mass, such as a corpus luteum cyst or a functional ovarian cyst. These masses are usually small and have no obvious symptoms and will resolve on their own within a few weeks.

2Lesions caused by inflammation or infection

Pelvic inflammatory disease, salpingitis and other bacterial infections are common gynecological diseases. The inflammation may develop into an abscess, forming a palpable or visible mass. Such conditions are often accompanied by systemic symptoms such as fever and lower abdominal pain, and require antibiotic treatment and drainage to prevent the spread or recurrence of infection.

3 Benign tumors or lesions

Uterine fibroids and benign ovarian cysts are common causes of pelvic masses. These benign lesions usually grow slowly, but when they are large, they can cause problems such as compression, menstrual abnormalities, or infertility. Treatment is mainly based on follow-up observation. When the mass exceeds 5 cm or causes symptoms, laparoscopic surgery can be used for resection.

4 Malignant lesions and tumors

Ovarian cancer or other malignant tumors may also cause pelvic masses, especially when accompanied by weight loss, loss of appetite, pelvic pain and other symptoms, you need to be highly vigilant. Ultrasound, CT, MRI and tumor marker testing are commonly used diagnostic methods. If a malignant lesion is confirmed, combined treatment methods such as surgery, chemotherapy or radiotherapy are required.

If you find a mass in the pelvis, regardless of whether you have obvious symptoms or not, you should see a doctor as soon as possible and have a professional examination to confirm the cause. Standardized treatment can not only alleviate symptoms, but also prevent the malignant progression of the mass or the occurrence of complications.
