In brief: 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.

In brief: Abnormal cells grow

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