Genetics test could help treat cancer patients

Doctors believe a new genetic test can predict which patients with early lung cancer face a higher risk of having the disease return.

Researchers examined the molecular genetics of lung cancer in two different studies. Experts hope the test can help them see which patients will need just surgery for lung cancer and which will require chemotherapy afterwards.

The study appears in the journal "Lancet."
