Diagnosed with breast cancer, will a natural remedy wellness clinic work?

My aunt has just been diagnosed with breast cancer. can you kindly explain what this measurements are on the biopsy report? 5s/2c and further stated 1.3 x 1.1.

She is planning on using another method of treatment at a wellness clinic called Utopia in Florida, which treatment involves natural remedies and vitamins minerals etc, for a period of 8 weeks. If it is not successful, will her cancer spread during that time? How fast does cancer spread?
