Home ozone therapy choice for breast cancer?

My wife has breast cancer. We’re trying some alternative treatments… We also want to try ozone. She’s drinking ozone water made with this cheap ozone generator:
Aqua-6 Ozone Generator Ozonator Water Air Oil Purifier 600 mg/h . She is also trying ozone bagging with that ozone generator using a regular plastic bag. (BTW, for how many minutes and times a day this should be done? )

 What other forms of ozone administering are workable for breast cancer? Is it vaginal or rectal or ear insufflation? Which one will be more beneficial? And could you please, give me tips on using  the preferred methods? I know that a medical grade ozone is needed for that, but I can’ afford it now. Some people here had success with these cheap generators, so I’m hoping to be able to use such as well. Thank you.
