Flattie 

A breast cancer survivor that is FLAT after a mastectomy. It can be a double or single mastectomy, a survivor or previvor.

It can be because they chose not to get implants immediately or because they had to have their implants removed for one reason or another. An example of why they had them removed, they made them sick.

A friend just got diagnosed with breast cancer and said she wasn’t getting implants. I told her she would have to come with me to a Flatties meet up.
