In younger women, they are more common, thus in patients under the age of 21, 60% of ovarian tumors are of the germ-cell type, and up to one-third are malignant. In males, GCTs of the testis occur typically after puberty and are malignant (testicular cancer). In neonates, infants, and children younger than 4 years, most are sacrococcygeal ...
The risk of ovarian cancer increases with age. Most cases of ovarian cancer develop after menopause. [16] It is also more common in women who have ovulated more over their lifetime. [17] This includes those who have never had children, those who began ovulation at a younger age and those who reach menopause at an older age. [5]
This system bases malignancy classification on the histological traits of the tumor (type of tissue). This is opposed to the classification of adult malignancies, which are categorized according to the primary tumor site. The latest iteration of the ICCC is ICD-O-3/WHO 2008, which was updated to reflect hematopoietic codes. [1]
Dysgerminoma accounts for less than 1% of ovarian tumors overall. Dysgerminoma usually occurs in adolescence and early adult life; about 5% occur in pre-pubertal children. Dysgerminoma is extremely rare after age 50. Dysgerminoma occurs in both ovaries in 10% of patients and, in a further 10%, there is microscopic tumor in the other ovary.

The ovarian disease has two forms, juvenile and adult, both characterized by indolent growth, [1] and therefore has high recovery rates. [ 2 ] [ 3 ] The staging system for these tumours is the same as for epithelial tumours and most present as stage I. [ 4 ] The peak age at which they occur is 50–55 years, but they may occur at any age.
Ovarian tumors, or ovarian neoplasms, are tumors in the ovary. [1] Not all are ovarian cancer. [1] They consist of mainly solid tissue, while ovarian cysts contain fluid. [2]In 2020, the World Health Organization (WHO) divided ovarian tumours as 90% epithelial, 3% germ cell, and 2% sex cord-stromal types.
The TNM Classification of Malignant Tumors (TNM) is a globally recognised standard for classifying the anatomical extent of the spread of malignant tumours (cancer). It has gained wide international acceptance for many solid tumor cancers, but is not applicable to leukaemia or tumors of the central nervous system .
