Tell me what you know about cancer treatments?

My mom may soon be receiving Aredia via IV for three months to treat elevated IGA antibodies in her blood. I’m not really looking for sympathy, but thanks anyway. She’s been a nurse for almost 40 years, so she knows a lot about multiple myeloma. Her doctors say that the elevated antibodies could turn into cancer if they are not slowed down (or however you stop the from multiplying).
My mom does not want the treatment because of the possibility of renal failure from it overworking the kidneys. Kidney issues run in her side of the family. My cousin’s in renal failure as we speak.

What do you know about other medical treatments or alternative medicines to treat the causes of multiple myeloma? She and I are especially interested in the alternative medicines she can use to complement the traditional.

Thanks, y’all.
