Invasive procedures are medical techniques that involve entering the body, often through incisions or punctures, to diagnose or treat conditions. These procedures can include surgeries, biopsies, and catheter insertions. They are typically performed in hospitals or specialized clinics and may require anesthesia to minimize discomfort. While invasive procedures can be effective in addressing health issues, they also carry risks such as infection, bleeding, and complications from anesthesia. Medical professionals carefully evaluate the necessity of these procedures, considering factors like the patient's overall health and the potential benefits versus risks involved.
