Alternative treatments

I have had a total thyroidectomy due to papillary thyroid cancer in 2914, a radical cystectomy due to bladder cancer in 2022. The bladder cancer seems to be taken care of. All scans back clear. The thyroid is a different animal. I now have metastatic thyroid bone cancer in my left hip and right shoulder. I had external beam radiation in August. The results were underwhelming, at least to me. I have another scan in March or April to see if there is any improvement.
But, I'm here to ask if any has any knowledge of Ivermectin and Fenbendazole as treatments. I have read both promising and inconclusive studies. I'm thinking it may be worth a shot
