Question

how have medical surgeries evolved over time?
surgeries have become more invasive.
surgeries now aim for minimal invasiveness and shorter recovery times.
surgeries now require longer recovery periods.

Explanation:

Medical advancements have led to the development of minimally - invasive surgical techniques. These techniques reduce the physical trauma to the patient (less invasiveness) and, as a result, lead to shorter recovery times. For example, laparoscopic surgeries are less invasive than traditional open - surgeries and patients recover faster.

Answer:

Surgeries now aim for minimal invasiveness and shorter recovery times.
