Single moms

So I'm trying to decide if I should just go have a baby. No, I'm not taking this decision lightly. I have no SO in my life, and there are no prospects. What I do have are lots of ovarian cysts. Every female in my family has had a hysterectomy from ovarian cancer. I assume it's only a matter of time for me too. I'm 30. Should I continue waiting for Mr. Right and risk my chance? How hard is it to be a single mom? I know women do it every day and survive.
