gallium maltolate for pain relief and cancer cure

Gallium Maltolate has reduced my friends pain 50-80% making it manageable. He has stage 4 prostate, secondary Bone Cancer; Tumor in spine paralyzed him but he's recovering after immediate surgery. Gallium mimics iron, which cancer feeds off of, causing cancer cells to go into apoptosis. He has very low hemoglobin which could be his body's way of fighting cancer instead of feeding it.
