Most ovarian tumors are benign (non-cancerous), but a significant percentage are malignant, especially in older women, with common epithelial types making up 90% of ovarian cancers, while rarer germ cell and stromal tumors account for fewer cases but often have good prognoses. A study found that complex cysts in older women might have a 6.5% chance of being cancerous within three years, but the overall lifetime risk of developing ovarian cancer is around 1.4%.
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. There are several subtypes of germ cell tumors.
Ovarian cysts that persist may require surgery for diagnosis and treatment. A 2019 study found that a higher percentage of complex ovarian cysts may be cancerous, estimating that among those age 50 or older, 6.5% of individuals with complex ovarian cysts may be diagnosed with ovarian cancer within 3 years.
Lifetime risk of ovarian cancer
A woman's risk of getting ovarian cancer during her lifetime is about 1 in 91. Her lifetime chance of dying from ovarian cancer is about 1 in 143. (These statistics don't count low malignant potential ovarian tumors.)
Approximately 20% of women with advanced-stage ovarian cancer survive beyond 12 years after treatment and are effectively cured.
The most common symptoms of ovarian cancer
Ovarian cancer is often referred to as “the silent killer” for a good reason: It ranks as the fifth deadliest cancer among women. In fact, of the 22,530 women who will receive an ovarian cancer diagnosis each year, nearly 14,000 of them will die from it, according to the American Cancer Society (ACS).
Main causes of ovarian cancer
You may have a higher chance of getting ovarian cancer if you: inherited a faulty gene, such as the BRCA genes or those linked to Lynch syndrome. had breast cancer or bowel cancer. had radiotherapy treatment for a previous cancer.
Ovarian cancer most frequently develops in women 55 to 64 years old and in women who began menstruating before age 12 or reached menopause after age 50. Higher risk also is associated with: Obesity.
About 90% of women diagnosed with ovarian cancer have epithelial ovarian cancer. This type of cancer starts on the outer surface of the ovary and has few established risk factors and the worst prognosis. It's the deadliest type of gynecological cancer.
Any time tumor marker levels are elevated, it makes us more suspicious that a pelvic mass might be ovarian cancer. But tumor markers can still be elevated, even if someone doesn't have ovarian cancer.
Cysts that appear uniform after an ultrasound exam or a CT scan are almost always benign and should simply be watched. If the cyst has solid components, it may be benign or malignant and should have further evaluation.
Studies have found that endocrine dysfunction, inflammation, stressful environments and genetics are the main causes of ovarian cysts in women. Moreover, ovarian cysts have been linked to a variety of psychological disorders.
Most epithelial ovarian cancers are now thought to start in the nearby fallopian tube, but it's very difficult to find cancer there before it spreads to an ovary. Germ cell ovarian cancer and stromal ovarian cancer are rare types of ovarian cancer.
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.
Genetic mutations – Mutations of the BRCA1 or BRCA2 genes significantly increase a woman's risk of ovarian cancer. Obesity – If you have a body mass index (BMI) of 30 or higher, you may be at increased risk of ovarian cancer.
The 2 tests used most often (in addition to a complete pelvic exam) to screen for ovarian cancer are transvaginal ultrasound (TVUS) and the CA-125 blood test.
Women who have never been pregnant and given birth have a higher risk of developing epithelial ovarian cancer. It is possible that the higher risk in women who have never been pregnant is linked to the factors that may make it difficult for her to become pregnant.
Removing the ovary can be crucial in treating ovarian cancer, but it's not a cure on its own. Oophorectomy works best with treatments like chemotherapy and targeted therapy. The decision for surgery should involve a qualified oncology team to evaluate all options.
No. A Pap test can't reliably detect ovarian cancer. A Pap test is a procedure that involves collecting cells from your cervix and examining them under a microscope. A Pap test can detect cervical cancer and changes in your cervical cells that may increase your risk of cervical cancer in the future.
As with most cancers, ovarian cancer becomes more common as you get older. The risk of ovarian cancer increases steeply from around 45 years. And is greatest in those aged between 75 and 79 years.
Bloating, diarrhea and abdominal pain are three of the most common ovarian cancer symptoms. The bloating can be so severe that it distorts your appearance. Feeling full quickly and heightened fatigue are two other ovarian cancer symptoms.
Treatment for ovarian cancer
The main treatments for ovarian cancer are surgery and chemotherapy. Your treatment depends on several factors including your cancer stage and grade.
Ovarian cancer is known as the “silent killer” due to the difficulty in early detection because most women do not have any early symptoms. As with other cancers, the earlier the diagnosis of ovarian cancer is given, the greater the chance can be for a good outcome.
