Breast lift and augmention is unsafe?

I recently consulted with a plastic surgeon for breast augmentation. He recommended also doing a breast lift, but said they need to be separate surgeries because the complications are significantly higher when they are done together. Is this true or is he trying to get me to do two sugergies? What does the cdata suggest? I am a healthy, athletic non smoker in my 30s, no pregnancies or prior surgeries.
