already approved antibiotics to the rescue?? schoolgirls innocent question may have

I think you might have misheard

It is possible that breast cancer might be caused by a virus-- many head and neck and cervical cancers are-- but antibiotics are not effective against viruses

If these antibiotics work against some forms of cancer it may be because they target the mitochondria (as mitochondria have an evolutionary relationship with bacteria, being believed to have descended from bacteria) which are differentially sensitive in cancer vs normal cells
