What do i do with an cyst?

See your doctor: Cyst treatment depends on location, size, and likely recurrence. Often a biopsy is done to confirm that it is benign. Options include doing nothing, reducing or removing it. Reduction is done because it is too dangerous to remove. Benign cysts can be removed for cosmetic reasons or to prevent recurrence. If it presses on a body part and causes dysfunction, then it should be excised.
