There is a book called “Prayer Passport to Crush Oppression” by Dr. Daniel Olukoya that contains prayers for dismantling cancer which can be a demonic attack. Here is one of those prayers. (There are a number of other such prayers on the internet.)
The name of JESUS is above ALL names, and ALL things (Phil. 2:9). That includes cancer!
“But he answered and said, Every plant, which my Heavenly Father hath not planted, shall be rooted up. ” (Matthew 15:13)
“And ye shall serve the Lord your God, and he shall bless thy bread, and thy water; and I will take sickness away from the midst of thee.” (Exodus 23:25)
1. All the activities of silent killers in my body, die, in the name of Jesus.
2. You symptom of cancer in any area of my body, die, in the name of Jesus.
3. Every evil growth in my body, I curse you to die, in Jesus name.
4. I fire back every arrow of cancer, in the name of Jesus.
5. Every abnormal production and uncontrollable behaviour of cells in my body, stop, in the name of Jesus.
6. I bind every spirit of death and hell, in the name of Jesus.
7. Every negative consequence of abnormal production of cells in my body, die, in the name of Jesus.
8. I shall not die but live to declare the works of God, in Jesus name.
9. You mass of extra tissue that has become malignant in me in my …………………………be melted by the fire of God, in the name of Jesus.
10. Every demon of cancer, I bind you and cast you out, in Jesus name.
11. Every vampire spirit, release my life, in the name of Jesus.
12. You malignant tumour, go back to your own kind by fire, in the name of Jesus.
Any demon involved in this sickness I rebuke you in the name of Jesus and command you to come out now.
Now lay your hands on the affected part of your body and pray like this:
Evil growth, dry up and die, in the name of Jesus. Any and all satanic instructions to my body, be dismantled now, in Jesus name. Every poison in my body, come out through the mouth and through the nose, in the name of Jesus.
Every spirit behind this cancer, come out with all your roots, in the name of Jesus. Come out all the way out now in the name of Jesus. I command you to leave. You have to go now.
Every cancer anchor in my body, be dismantled in Jesus name.
Every vehicle of cancer, die, in the name of Jesus.
Power of cancer, die, in the name of Jesus.

I dismantle every hand of witchcraft, in the name of Jesus.
Every threat to my life, my God shall threaten you to death, in the name of Jesus.
By the power of the stripes of Jesus, I kill every power of cancer, in the name of Jesus.
