Answers

Hank is undergoing thoracic surgery, which means he is having an operation on his chest.The correct answer is option B.

Thoracic surgery refers to surgical procedures that involve the organs and structures located in the chest cavity, including the heart, lungs, esophagus, and major blood vessels. This type of surgery is performed to treat a variety of conditions such as lung cancer, heart disease, esophageal disorders, and thoracic trauma.

During thoracic surgery, the surgeon gains access to the chest cavity through incisions in the chest wall, allowing them to access and operate on the affected organ or structure.

The specific procedure performed will depend on the underlying condition being treated. Thoracic surgeons are highly specialized and trained in various techniques, including minimally invasive procedures such as video-assisted thoracic surgery (VATS) or robotic-assisted surgery.

The goal of thoracic surgery is to diagnose, treat, and manage conditions affecting the chest region, aiming to improve the patient's quality of life, relieve symptoms, and potentially extend their lifespan. The surgical team works meticulously to ensure the best possible outcome for the patient, considering their overall health and individual circumstances.
