One mutant cell: One normal cell inside your breast mutates (becomes abnormal), and begins to grow. The normal "stop" signal that tell a cell to stop dividing doesn't work, so the cells keep dividing. One cell becomes two, two become four, four become eight, etc. It takes millions of cancer cells to form a tumor you can feel.

Abnormal cells grow: Takes years unless you have a particularly fast growing type associated with brca1 and brcaii genes.

Not sure..: If i understand your question correctly, but breast size has no bearing on who may get breast cancer. Have a yearly physical examination with your doctor, and if there is a breast lump or concern see your doctor soon.
