This phase II trial determines the effect of metformin extended release on the risk for
developing lung cancer in overweight/obese patients that are at high-risk for developing lung
cancer. Metformin is widely used to treat type II diabetes and has a long history of safety
and minimal side effects. At similar dosage, the drug may have potential anti-cancer
activity. Metformin use has been associated with improved survival in patients with non-small
cell lung carcinoma, a specific type of lung cancer, and it has also been shown to enhance
immune mobilization against tumors. This trial aims to see whether metformin extended release
as a preventative treatment may lower the chance of developing lung cancer, and whether it
may help patients' immune system learn ("reprogram") to lower a certain type of immune cell
(called regulatory T cells) that are linked to tumor development.
