Syracuse, NY -- U.S. Army Sgt. Brandon Hinman said the next 48 hours are crucial for his wife who is battling a rare, life threatening cancer.

Jenna Hinman faced a major setback in her recovery over the weekend when she developed pneumonia.

Brandon Hinman said his wife is not doing well, but she's continuing to fight. Jenna Hinman has been on life support at Crouse Hospital for nearly two months. She remains in critical condition.

Jenna Hinman gave birth to Kinleigh Ann Hinman and Azlynn Mary Hinman by emergency C-section March 3 only to have doctors immediately discover she was battling stage 3 choriocarcinoma. The twins, who were delivered premature, remained in the neonatal intensive care unit for six weeks.
