Anesthesia techniques extend far beyond the obvious of numbing an area to pain in order for a medical procedure to take place for the patient. From pre and post-operative care to assisting in healing long term there are a number of ways that anesthesia can benefit patients facing a number of medical concerns. There is a growing amount of research that shows regional anesthesia can have a positive impact on, not only care for cancer treatment patients, but on survival rates as well.
