I had an induced abortion at 14 weeks pregnant . i've also had an induced abortion at 4 weeks pregnant and a miscarriage at 8 weeks pregnant. do i have a high chance of breast cancer ?

No I do not believe that this increases your risk. If you have a risk of breast cancer in your family, this can have an effect. I would suggest some contraceptives to avoid the pregnancies until you are ready for children.

Abortions, induced or spontaneous would not raise your risk of breast cancer. Your family history is more important. Maintain a healthy weight, abstain from tobacco and alcohol.
