I'm no expert in this, 'cause I still get sick sometimes and that tells me I obviously haven't believed like I should, but what about trusting and believing in God for your health? There is no cancer (or any sickness/disease) mightier than what God has done (Isaiah 53:5 says that by His stripes we were healed). Like I said, I'm no expert in that area, but praise God I'm getting there. Besides that, though, this isn't widely taught or received (as far as I know). Besides Isaiah 53:5 (and 1st Peter 2:24), there are other verses in Proverbs and Psalms that talk about healing, too (Proverbs 17:22, Psalm 42:11, Proverbs 4:20-22, etc.).
