What case should I file for suppressing a material fact /Fraud? For Nullity or for Divorce

I am Bhargav native of Andhra working in Hyderabad. I recently got married on 8th August 2020. The one to whom I got married is from Hyderabad and native of Vijayawada. The girl to whom I got married undergone a surgery in Oct 2018 and one of her Ovary was removed due to torsion. This was not informed to us prior to marriage. Due to this surgery there were several other complications to her like low back pain etc. I found a scar on her lower abdomen and asked her what it was.She just told me that she has undergone a surgery for removal of ovarian cyst. After that I went to girls house and stayed there for 2 weeks and gathered the documents and found that one of her ovary was removed. Her parents nor her were not even responsible for informing the same to me or to my parents before the marriage. They did this intentionally to hide the fact that if this was known prior no one will proceed or show consent for the marriage.Only when I asked them they revealed about her daughter's surgery about ovary removal. After that I returned to my home and the girl is staying with her parents. I had gathered the medical reports of her surgery as proofs and also have the voice recordings of her parents stating that it was their mistake for not informing about the surgery before. Can you please help me on what cases do I need to file for nullifying my marriage or in case if nullify doesn't happen for divorce. Thanks.
