Palliative care seeks to manage symptoms of advanced illness through a holistic, multidisciplinary approach. A study found that early palliative care for metastatic lung cancer improved quality of life and mood, and led to less aggressive end-of-life care without negatively impacting survival time. Opioids are effective for dyspnea when appropriately dosed and monitored, while supplemental oxygen and benzodiazepines may also provide relief. Defining standards for palliative care is important for research.
