Sorry your mom isn't well. My own Mother passed before she was sixty. I just wish I had known then what I know now.
I've just started using DMSO and MSM and read tons of stuff about them first. There is a lot of discussion about DMSO helping carry whatever cancer medication is used directly to the cells. I remember one discussion about nebulizing it for lung cancer. Others used a drop or two under the tongue three times a day.
DMSO is very controversial but I know you would do your homework before using or not using it. People still give us shite about Iodine too.
Dr. Stanley Jacob is probably the best supplier of a pure product. That's not where I ordered but I'm not using it internally.
