Hi, My mother in law was diagnosed with cancer 5 years back. She has struggled too much and doctors had left hope as it was the final stage. but fortunately she recovered. I got married to her son 2 years ago. We want to try baby now. But doctors say her cancer can be genetic and affect my husband's Sperm . Should we do genetic or chromosome testing? I don't have much knowledge about her cancer since I got married after she was recovered
