If my biopsy came back with severe dysplasia level 3, does it mean that i have cervical cancer?

May not be: Type iii dysplasia means, 2/3 of the cells of the lining are abnormal.Could be a carcinoma in situ ( means safe , cancer cells are not invading ) only your expert can answer after further tests, need close monitoring and treatment.

Needs follow-up: For level 3 pap, you need to have a discussion with your doctor for follow-up testing, repeat pap, colposcopic examination and may be biopsy. You may or may not have cervical cancer, but you need to get follow-up testing.
