Following breast cancer 7 years ago i had a mastectomy and augmentation. It would now appear that one of the implants have burst, not sure when. Reading some information i have been suffering various side affects for the last couple for years: Brain fog, weight gain, chest pain, back ache are the main effects. I am waiting for an MRI and suspect i may need them removed, But then what...dont want to be left flat chested but dont want to endue these side effects..help
