Resolved question:
Hello Doctor,
I am an Information technology student in USA, I am doing thesis. We are developing a software tool to calculate the mutation risk of BRCA1,BRCA2, Tp53 and PTEN gene of breast cancer. We are using family history to detect the presence of faulty gene in the family. I want to know how you can predict the probability of mutation risk of the consultant using Bayes Theorem?
For example, if the consultant grandmother (maternal) and her aunt (maternal) had breast cancer. How do you calculate the probability of cancer in the consultant using Bayes Theorem?. How do you calculate prior probabilities and conditional probabilities in this case?
Could you please help me. I don't have any other source to clear my question.
Thank you very much
Sincerely

Hello,
Thank you for your query at DoctorSpring.com
Since he ejaculated outside you, there is no concern for pregnancy here.
The literature says that precum can lead to pregnancy in rare cases, however that is more theoretical, and practically I haven't seen a case getting pregnant from precum.
Also it was day 22 of your menstrual cycle, so it is pretty late and ovulation would have occured around the 15th day. So again practically there is no chance of pregnancy.
Feel free to discuss further,
Regards.
Thank you for your response so quickly. Just one follow-up question-i am scheduled to have my period by Thursday of this week. If that occurs, would that be 100% reassurance?
Hello,
Yes definitely.
Period is the most conclusive evidence of no pregnancy.
Hope this was helpful,
Regards.
