Considering CPAP

Hey guys I’m dealing with bad sleep for 2 years, I did a sleep study last year, and . I was diagnosed with Mild sleep apnea/hypopnea syndrome and mild nocturnal hypoxemia. My question is : Is worthy to treat it or not? My average AHI is 6.1, but when lying on my side is 1.3 and when lying on my back is 10.8, the doctor recommended me to do surgery rather than CPAP, I have septal deviation and turbinate hypertrophy.
