I think some people believe there are alternative treatments for cancer. I’m not saying to skip the mainstream therapy, but just that maybe you could also look for complementary therapy and do them both. I know there are some people who have done well with cancer. You can find their stories online if you search for them
Dm127, I am praying for you
Dear heavenly father, please send Your infinite healing power to this dear man. In the name of Jesus, Amen
