"She got 16 to 32 months, but that's like a life sentence if she doesn't get her proper care," Arnold's daughter, Toni, said.
Arnold's attorney, Heidi Eakin, said the bail set by Senior Judge John Braxton is significant but one the family will attempt to raise.
"We just asked for reasonable bail. And the definition of reasonable is anywhere from nothing to bail that's impossible to post. I'm not saying this is impossible to post," she said. "We just have a little work to do."
Braxton has not ruled on the motion to reconsider the sentence he imposed Tuesday, but Eakin said she expected the judge may schedule a hearing. If that happens, the attorney said, she would present medical records and possibly testimony from a doctor.
Meanwhile, Arnold's family and other supporters plan to gather at 9 a.m. Monday outside the West Chester courthouse to protest her sentence.
Arnold has been transferred from the Lehigh County Prison to the state prison in Muncy since her sentencing, according to Eakin. She is being held in the facility's hospital.
"I want her out on bail so she can receive treatment from her local oncologist and surgeon who understand the severity of this cancer," Eakin said, adding that Arnold is scheduled to begin an eight-month chemotherapy regimen in November.
According to the Attorney General's Office, Arnold told an employee to "hold onto" a citation that had been filed against one of her adult sons for fighting with her other son, resulting in its not being docketed for 21/2 months.
That employee was later subpoenaed, and prosecutors say Arnold attempted to have her fired.
