Hello
It seems that you are really neglecting
1.Cysts are uncommon for your age
2. You're having cysts in one
kidney only that indicates it was an acquired cyst only and not from birth
3.You should get evaluated totally what was the reason for cyst s formation, if it comes to another kidney then it's a problem
4. you should periodically monitor the size of cyst every year.
Good thing in your case is opposite kidney has reasonably increased in size
