Roxy Jacenko's jailed husband Oliver Curtis to appeal conviction after breast cancer diagnosis.

Jailed banker Oliver Curtis is set to appeal his conviction while his wife Roxy Jacenko begins treatment for breast cancer.

Curtis, 30, was sentenced to two years in prison on June 24 after a Supreme Court jury found him guilty of conspiracy to commit insider trading.
