My mother found out she had breast cancer last summer. She's doing fine now, but she had a hysterectomy recently and they found basically a tumor before it became cancerous. They said she had (and has had it for a while) a disease that leads to Ovarian cancer, I can't remember the name of it at the moment. She got the gene mapped out that could cause breast cancer mapped out, but it came back negative. The people at the genetics test said they could do a blood test for the best results, but I wouldn't be able to get the results until I'm 18.

What are my chances of getting one or the other, or both?
