Normal breast in section. We observe in 3 the mammary gland, in 7 the adipose tissue, and in 2 the large pectoral
The Tillaux maneuver consists of palpating the tumor mass, while asking the patient to perform an armored adduction of the arm: the patient tries to bring the arm of her body against the pressure exerted by the doctor who away from it. This maneuver has the effect of contracting and displacing the pectoralis major muscle. Thus, the doctor will appreciate the mobility or, on the contrary, the fixity of the tumor in relation to the deep plane constituted by the pectoralis major.
When the tumor is limited to the breast, it will remain mobile with respect to the pectoralis major. On the other hand, a fixity sign implies an invasion of the deep plane by the tumor, thus a greater extension of this one.
