Because a lung cancer diagnosis and lung cancer treatments are increasingly complex and continue to rapidly change, some oncologists may not be familiar with all of the most current research and available clinical trials. It is very acceptable and strongly advisable to get a second opinion. However, if your lung cancer is making you feel very sick, you may not want to delay treatment while trying to set up this appointment. There are many cancer centers nationwide with highly trained thoracic oncologists available to render second opinions. They will be able to talk with you about standard treatment options that you may be able to receive closer to home, as well as the more recent developments in the treatment of lung cancer and review available clinical trials.
