based on type of epithelial tissue and whether the tumour is malignant or benign

ovarian and testicular cancer malignancy comparison
ovarian teratomas are usually benign
testicular teratimas are usually malignant
Features of benign tumours
-non-invasive growth pattern
- usually encapsulated
-no evidence of invasion
-no metastases (secondary tumours)
-cells similar to normal so they are well differentiated
- have a function similar to normal tissue
rarely cause disease
