Lung Center

Lung Center of Nevada, a division of Comprehensive Cancer Centers of Nevada provides dedicated services for patients with lung cancer as well as various pulmonary diseases and sleep disorders.

With a renowned team of medical oncologists, radiation oncologists, surgeons, and pulmonary specialists working together in a multidisciplinary approach, Comprehensive is able to implement individualized treatment plans without the need for the patient to travel outside of the practice.

Our pulmonologists are also consultants for doctors in many specialties who need assistance in the pulmonary and intensive care areas. Often times, we are enlisted to manage patients in hospital ICUs who need ventilator support.

Sleep Disorders
Lung Center of Nevada also treats patients suffering from sleep disorders at Sleep Center at Comprehensive. There are a number of sleep disorders that can decrease a person’s quality of life and can cause problems if left untreated, including:

Sleep Apnea is a common sleep disorder caused by the soft tissue in the throat falling and blocking the airway. When this happens, our bodies naturally wake us up briefly to open the airway so we can breathe again. Sleep Apnea can cause complications down the road if not treated early. Treatment options range from machines that help with breathing to surgery. A board certified sleep medicine physician at Lung Center of Nevada will provide options to help determine which treatment is best for each individual patient.

  • Periodic Limb Movements of Sleep (PLMS)
