RISK OF MALIGNANCY BY AGE & MENOPAUSE

http://www.wdxcyber.com/ncanc08.htm

 

If you look at the distribution of ages in this study (confined to women over 30), you will see that benign tumors and causes of ovarian masses can occur in all age ranges. Malignancy of the ovary definitely is higher in older women and lower in frequency in the younger ages.

 

 

Risk of Malignancy Age Distribution

Age
(years)
Benign
(n=290)
Malignant
(n=75)
30-44 106 (37%) 11(15%)
45-54 104 (36%) 17(23%)
>=55 80 (28%) 47(63%)


After menopause, are not most ovarian masses malignant?

Just as there is an increased chance of an ovarian tumor being malignant at older ages, so is the chance after menopause. Benign pelvic/ovarian masses occur with almost equal frequency before and after menopause.
