Tumour volume in cubic millimetre (mm³) and tumour weight in absolute values (g) and relative values (percentage of the body weight (% BW)) on the day of euthanization per group. Mean ± standard deviation.

	Tumour volume (mm3)	Tumour weight (g)	Tumour weight (% BW)
Control	4015 ± 713	2.92 ± 0.47	0.79 ± 0.12
Betaine	1874 ± 1154∗∗	1.63 ± 0.94∗	0.48 ± 0.28∗∗
C-PC	473 ± 162∗∗∗$$$	0.21 ± 0.06∗∗∗$$$	0.06 ± 0.02∗∗∗$$$
