Yes, and yes. It can be completely cured. Actress and singer Kylie Minogue is one such example. And there is no other option to be absolutely certain of cure than to go in for western medicine at specialised hospitals. Steve Jobs and others have tried homeopathy and other traditional medicine, to no avail. While these have their benefits, they are not regulated and there is no evidence for their effects on cancer.
Hope you make the right choice and wish you or your own a speedy recovery.
