I want to get my skin to be paler, but I don't want to use whitening/lightening creams because I have heard that the chemicals can cause cancer or other various problems. Surgery is not an option either. So, I must resort to home-remedies. Any suggestions?

I would suggest to try some folk natural remedies like applying curd with lemon on the face and neck. Wash off after 15 minutes. For more such remedies you may visit this link. I am sure it would be of great help to you for all skin related probs. http://garima-sancheti.suite101.com/home-remedies-for-skin-care-a140955
