When can I start jogging?

I want to try to get fitter and have signed up to a beginners jogging class that starts tonight.  A friend said that her plastic surgeon said not to jog.  I have had breast reconstruction surgery about 2 and a half years ago using implants and my back muscles.  Has anyone heard anything about not being able to jog.  I would wear a really strong sports bra.......    I have left a message for my plastic surgeon but I am sure he won't hurry in coming back to me with advice.
