Hello dear , hi
Warm welcome to Healthcaremagic.com
I have evaluated your query thoroughly .
*  Guidelines for your questions  in sequence
1.  Suppositories give symptomatic relief , not cure for lifetime .
2.  Surgery is required if more pain , bothersome .
3.  It will not become cancerous for rest of your life .
4.  In my opinion , you need to consult  a  General  surgeon for guidelines
5.  It will not go away without surgery .
6.  
Laser is an option , for availability in Australia , have to consult local
     surgeon .
Hope this clears your query .
Welcome for any further  assistance .
