Can all cancers be treated with surgery?

It is impossible to remove some cancers surgically, even with cryotherapy. There are cancers of the bloodstream which are impossible to remove with surgery alone. These have to be treated with medicines because some cancers are systemic, meaning surgery is just a local treatment. It's not a regional treatment. It's a local treatment. In order for it to be effective, the problem has to be in one place and localized. It has to be a well-defined location where you know exactly the boundaries of the cancer. Any cancer that is moving outside well-defined boundaries cannot be cured by surgery.
