number in parentheses is final n value.

Values are mean ± SE

^{a, b}

Values within a row with different superscript letters are significantly different by Chi-square analysis. P<0.01

^{c, d, e}

Values within a row with different superscript letters are significantly different by Chi-square analysis: P<0.0001

Values within a row with different superscript star are significantly different by t-test (only AL and CCR, but not ICR –Only one mouse with weighed tumor).
