What percentage of ovarian tumors are benign?

How common are benign ovarian tumors?

Epidemiology. Benign ovarian tumours occur in 30% of females with regular menses (eg, luteal cysts as incidental findings on pelvic scans) and 50% of females with irregular menses. Predominantly they occur in premenopausal women; they may also occur perinatally.

Are most ovarian tumors benign?

Most ovarian germ cell tumors are benign, but some are cancerous and may be life threatening. Less than 2% of ovarian cancers are germ cell tumors. Overall, they have a good outlook, with more than 9 out of 10 patients surviving at least 5 years after diagnosis.

Can an ovarian tumor be benign?

Overview of ovarian tumors

Ovarian tumors are abnormal growths on the ovaries, the female reproductive organs that produce eggs. Ovarian tumors can be noncancerous (benign) or cancerous (malignant).

Do benign ovarian tumors cause symptoms?

Noncancerous (benign) ovarian growths include cysts (mainly functional cysts) and tumors. Most noncancerous cysts and tumors do not cause any symptoms, but some cause pain or a feeling of heaviness in the pelvis. Doctors may detect growths during a pelvic examination, then use ultrasonography to confirm the diagnosis.

How often are ovarian masses cancerous?

Germ cell tumors are more likely to appear in females under 20 years, accounting for 70% of ovarian tumors in this age group. Approximately 3% are malignant.

How long does it take for an ovarian tumor to grow?

Generally, epithelial ovarian cancer grows rapidly and presents as advanced disease at the time of diagnosis because patients do not experience symptoms in the early stages [3], [4]. However, it generally takes about 3–6 months for a cancer to double in volume [5].

Can you see ovarian tumors ultrasound?

Ultrasound is often the first test done if a problem with the ovaries is suspected. It can be used to find an ovarian tumor and to check if it is a solid mass (tumor) or a fluid-filled cyst. It can also be used to get a better look at the ovary to see how big it is and how it looks inside.

Are ovarian tumors always cancerous?

Ovarian tumors are most often benign, however, some types may develop into ovarian cancer if left untreated. Symptoms are rare and tumors are usually detected during a routine pelvic exam or Pap test. Treatment typically involves surgical removal of the tumor and sometimes the surrounding tissue or the affected ovary.

Which is the most radiosensitive ovarian tumor?

The TOV21G and CAOV4 lines showed the highest levels of radiation sensitivity, while HEY, and OVCA420 were the most radioresistant from the panel tested. Curiously, the control cell line IOSE29, derived from normal ovarian tissue, is intermediate in the range of radiosensitivities measured (Fig. 1).
