What Does This Lipid Profile Indicate?

my total cholestrol is 217. LDL:139, HDL:56, Try Glycerides: 113. This is the value since last 4 years after diet control and regular exercise. Should I start taking medication (80 mg statin) as prescribed by the cardiologist for 2 months and stop after that. or is it OK to leave it like that? My BMI is 22.5 and age 40 years
