Hi,Dear,Thanks for your query to HCM.
Dear I read your query and reviewed it with context to your query facts.
I understood your health concerns and feel Concerned about them.
Based on the facts of your query, you seem to suffer from-
Multiple 
Boils with White Heads,after shaving of the 
Scrotum.This is caused due to the infection of the hair follicles of the scrotum.
With summer,scrotal heat rises so the infection grows in these dormant 
folliculitis lumps on testicles,which leads to the pus formation.
This is treatable with antibiotics/anti-inflammatory and Surgical 
drainage in some cases.
So nothing to worry being Cancers.They are just Scrotal 
Pimples.
Hope this would help you to reduce worry with your problem.
Take care and wish you to recover fast and Live healthy.
Hope this reply would help you to plan further treatment with your family and specialist doctors there.
Welcome for any further query in this regard.
Good Day!!
