1. INTRODUCTION • Ovarian cancer is the most common cause of mortality in most parts of the world , and currently is the most common impediment to achieving desirable life expectancy in most countries. • Ovarian cancer is one of the most common gynecologic cancers that rank third after cervical and uterine cancer. • It also has the worst prognosis and them highest mortality rate

2. Ovarian cancer is the fourth most common cause of cancerrelated deaths in women and is the seventh most common cancer diagnosed. An estimated 200,000 cases and 125,000 deaths due to ovarian cancer occur worldwide annually. Its incidence is highest among the high-resource countries with the incidence being 9.3 per 100,000 women.16 Ovarian cancer has accounted for 4% all new cancer cases in women in the year 2017.

3. There were approximately 7,500 new cases of ovarian cancer in the UK between the years 2015 and 2017 and nearly 4,200 deaths due to ovarian cancer in the year 2017.17 This type of cancer develops most often in women aged 50–70 years.

4. Nearly 80% of the cancers are epithelial cell cancers which originate from the surface epithelium of the ovaries. Other types of ovarian cancers include germ cell tumours , sex cord stromal cell tumours and metastatic cancers. Primary peritoneal cancer and primary fallopian tube cancer are rare malignancies but share many similarities with ovarian cancer

5. Also, clinical management of these three types of cancers is similar . Therefore, they follow a common staging system. Based on the histologic, genetic and molecular evidence, it can be presumed that 80% of tumours that had been classified as originating in the ovaries or peritoneum may have developed in the fallopian tubes in reality.
