Rheological properties of healthy and cancer tissues under shear strain: Column A, the normalized storage modulus (G′) as a function of shear strain for different degrees of axial compression (0%, 20%, and 40%). The decrease of G′ with increasing shear strain depicts strain weakening and is greater for cancer tissues (red dots). Column B, the phase shift angle as a function of shear strain for different degrees of axial compression. Cancerous tissues became significantly more dissipative at increased shear strain (Column B). G′ was normalized to the minimum shear strain value.
