48
M/c type of benign cystic ovarian tumor?
Cystadenoma

What % of cancers in the female population are ovarian malignancies?
5%, not too common. Although it has a high mortality rate due to late stage diagnosis + low cure rate. Very deadly. (if not metastasized, survival rates close to 90%, however usually always has spread when diagnosed)

How complex is ovarian malignancy?
Very b/c cancer originates from at least 4 different cell populations. Many different environments for cancer to come from.

M/c form of ovarian malignancy?
Cystadenocarcinomas (epithelial) From chart: Epithelial = 65-75% Germ cell neoplasms = 15-20% Metastases to ovary = 5-10% Sex cord stromal = 5-10%
86
SF of ovarian malignancy?
-complex cystic masses with septations -very large up to 30-40cm -nodular or papillary growths/protrusions -ascites (bilateral disease suspicious of malignancy)
87
4 stages with ovarian malignancy?
