The present invention relates to methods of treating cancer through stasis induction, wherein said stasis-inducing treatment results in reduced blood flow to the cells of said cancer, leading to diminished tumor growth and/or tumor death. In one embodiment, the stasis-inducing treatment comprises administering a therapeutically effective amount of a chalcogenide, salt, or prodrug thereof. The method of treating cancer may optionally comprise an additional step of withdrawing a portion of blood from said patient, such that blood flow to said cancer is further reduced or eliminated. In additional embodiments, the method of treating cancer may optionally comprise an additional step of diverting a portion of the blood flow in said patient, such that blood flow to said cancer is further reduced or eliminated.
