Hi @Vishay6, welcome to the forum!
There is an Anti Cancer Treatment field available on Patreon and Youtube.
Advanced Healing and Senescent Cell Removal combined with that would probably help.
Anti Aging on Patreon, the Internal Alchemy series, the Eternity Redux tag (would probably support healing processes, and may also help directly with slowing/stopping cancerous cell growth, but I’m unsure whether it does), Bone Marrow Strengthening and Enhanement and Fat to Stem Cells may help support your body to help it heal.
