I suffered a meniscal tear, can I start training again?

My knee got injured 5 months ago, mainly due to weights lifting.
I got an X-Ray done and it didn’t show anything, so after I proceed to get a MRI where it says that it may be a ‘lateral meniscal tear. Minimal knee effusion’.
Should I be careful to go back to training with weights and running? Should I follow some sort of treatment?
