Abstract

The present disclosure is directed to generally methods for treating mammographic breast density and/or breast stiffness in a patient in need thereof, such as a premenopausal or perimenopausal patient, comprising the administration of an effective amount of androgenic agent and an effective amount of an aromatase inhibitor. These methods may also be useful in post-menopausal woman.

Claims

1. A method of treating mammographic breast density in a patient in need thereof, comprising administering to the patient:

i) an effective amount of androgenic agent; and

ii) an effective amount of an aromatase inhibitor;

wherein the method further induces breast involution of breast cells in the patient.

87. The method of claim 1, wherein the patient is peri-menopausal.

88. The method of claim 1, wherein the patient is post-menopausal.

89. The method of claim 1, wherein the patient is pre-menopausal.

90. The method of claim 87, wherein a patient'"'"'s breast has a mammographic breast density of 25% or greater via 2-D determination.

91. The method of claim 88, wherein a patient'"'"'s breast has a mammographic breast density of 25% or greater via 2-D determination.

92. The method of claim 89, wherein a patient'"'"'s breast has a mammographic breast density of 25% or greater via 2-D determination.

93. The method of claim 1, wherein the method increases a patient'"'"'s breast compression during mammographic visualization or detection of the breast.

94. The method of claim 90, wherein the method increases the patient'"'"'s breast compression during mammographic visualization or detection of the patient'"'"'s breast.

95. The method of claim 91, wherein the method increases breast compression during mammographic visualization or detection of the patient'"'"'s breast.

96. The method of claim 92, wherein the method increases breast compression during mammographic visualization or detection of the patient'"'"'s breast.

97. The method of claim 1, wherein the method reduces the mammographic breast density of a patient'"'"'s breast between one or more annual intervening mammographic detections.

98. The method of claim 94, wherein the method reduces the mammographic breast density of the patient'"'"'s breast between one or more annual intervening mammographic detections.

99. The method of claim 95, wherein the method reduces the mammographic breast density of the patient'"'"'s breast between one or more annual intervening mammographic detections.

100. The method of claim 96, wherein the method reduces the mammographic breast density of the patient'"'"'s breast between one or more annual intervening mammographic detections.

101. The method of claim 98, wherein the method reduces breast stiffness of the patient'"'"'s breast between one or more annual intervening mammographic detections.

102. The method of claim 99, wherein the method reduces breast stiffness of the patient'"'"'s breast between one or more annual intervening mammographic detections.

103. The method of claim 100, wherein the method reduces breast stiffness of the patient'"'"'s breast between one or more annual intervening mammographic detections.
