The Claim

In postmenopausal women, regardless of breast cancer history, engaging in progressive resistance exercise training three times per week for 12 weeks is associated with an approximate 5–8% increase in quadriceps muscle thickness as measured by ultrasound imaging.

Source: Skeletal muscle mass, strength, and physical performance gains are similar between healthy postmenopausal women and postmenopausal breast cancer survivors after 12 weeks of resistance exercise training

In plain English

If postmenopausal women do strength training three times a week for three months, their thigh muscles get about 5 to 8% thicker — whether or not they’ve had breast cancer.
