Spaying a female dog before her first heat primarily reduces the risk of which cancer?

Explanation:
Spaying removes the ovaries, the source of estrogen and other hormones that stimulate mammary tissue. Because many mammary tumors in dogs are hormone-driven, eliminating ovarian hormone exposure early in life greatly lowers the chance of developing breast cancer, with the strongest protection when done before the first heat. The other cancers listed aren’t primarily affected by female reproductive hormones, and prostate cancer occurs in males, so spaying a female doesn’t impact it or necessarily change the risk of liver or kidney cancers.
