Summary

To ascertain the possibilities to isolate the breast cancer olfactive signature

Detailed description

Patient recruitment during the first surgery consultation in Curie Institute. Odor sampling (non-invasive) with an odor-sensing polymer (Sorbstar® polymer developed especially for the trace level analysis), on: * The hands, before and after surgical excision of the tumor (friction of the hands) * The diseased breast, before and after surgical excision of the tumor (via a compress positioned on the breast for 1 night) * The tumor, during the surgical procedure (odor collection over a tumor sample). Each patient will be her own witness, before and after surgical excision, in an attempt to isolate the chemical signature tracks of breast cancer. The samples after surgery will be made after healing and before implementation of a treatment (chemotherapy and / or radiotherapy).
