Chemotherapy can damage many organs including the liver. See "Organ Damage" on Wikipedia: https://en.wikipedia.org/wiki/Chemotherapy

A friend's sister beat colon cancer over ten years ago but now is having liver problems that took a while to pin down. They warned her she'd probably die in a couple years from the cancer without Chemo, but would have this risk long term and it recently showed up.
