Can steristrips be left on for too long following breast lift and augmentation? (Photo)

I'm 3 weeks po b/l b/a with lollipop incision. I've had steri-strips on since surgery on 3/5. They are sticking good & No signs of irritation or infection. My 3 week post-op appointment was cancelled & rescheduled for 2 weeks from now which would put me at 5 weeks post-op. My PS's nurse said to leave steri-strips in place until my appointment. Is it possible to leave steri-strips on for too long? Is there any harm in this or could it actually be beneficial for healing & minimizing scarring?
