Figure 3. Increased extracellular levels of dispensable amino acids, but not glucose and lactate, in dense breast tissue in vivo.

On regular screening mammograms women, who were categorized with breasts characterized as either dense (BI-RADS D) or nondense (BI-RADS A) tissue, were invited to participate in this study as described in the materials and methods. Women with dense (n = 20) and nondense (n = 18) breasts were subjected to microdialysis in the left breast to sample extracellular amino acids, glucose and lactate.
