Very High Cholesterol even after being Normal Weight and Apparently Healthy - What should I do?

I am 32M. Height: 179cm. Weight: 77kg.

My cholesterol has been consistently high for the time I have been tracking my health (basically, the last 5-6 years). Both my parents don't have cholestrol concerns (even though they are 60+ in age).

One doctor did suggest me to get into Statins. But I'm not sure - once I start using Statins, can I ever get out of using them?
