I have read that dcis is not yet cancer, but pre-cancer..so why take the drug???!!! Check books by Susazze Somers on her interviews with prominent MD's….it is all about hormone imbalance…I take beta glucan and Wii be three years cancer free…my cancer antigen test is 5, and anything under 38 is normal says my onc. I had stage 2 because I let lump go for three years before mammogram and disgnosis. I am 83…took no Als..and no radiation and my oncologist says she doesn't know what to make of it!!! She is astounded….there were serious reason I did nothing but lumpectomy…….going to dentist is worse for me!!!! Than lumpectomy.
