I would encourage you (whether you are sick or not) to start reading the Scriptures on healing as many times as you can during the day...out loud. Why? Because God hears you, His angels hear you and your body hears you. If you are a born-again believer in Christ Jesus, then you have authority over your body. You are the righteous of God and your body is a blessing to God. Also, continue listening to the Scriptures on healing. I listen to these at night time while I sleep. I have them on my iPhone, and scriptures continually play throughout the night. You can listen to these for FREE online, or order one. Just put it into your CD player. During the day, read scriptures on healing out loud. Print scriptures on healing and post them around your house.
Keep doing this until it gets down in your heart. Make the time to do it. When you go to the doctor and he prescribes you medicine, what do you do? You take it and expect to get better. If the doctor says you need surgery, what do you do? You make time and have the surgery. Well, same thing with God's Word. The Word of God is medicine to your flesh. Harken to His Words, obey God and diligently seek Him. Don't say you don't have time. Jesus died on the Cross and bore those stripes and you WERE healed!
Have a Blessed day,
Healed of Cancer
