All subjects will be given 2-4 weeks of probiotics prior to surgery in operable stage I-III breast adenocarcinoma tumors ≥1.0 cm. Subjects will take the probiotic three times a day.
Dietary Supplement: Probiotic
Primal Defense Ultra® Probiotic Formula is an over-the-counter probiotic that provides 15 billion colony forming units of 13 species of beneficial bacteria, including Saccharomyces boulardii, Lactobacillus plantarum, Bacillus subtilis, Bifidobacterium lactis, Bifidobacterium bifidum, Lactobacillus rhamnosus, Bifidobacterium breve, lactobacillus casei, Lactobacillus salivarius, Lactobacillus acidophilus, Lactobacillus brevis, Bifidobacterium longum, and Lactobacillus paracasei.
