American Sarah Shourd is feeling "strong and healthy," according to a source close to the hiker's family.
After almost 14 months of mostly solitary confinement in Iran on charges of espionage, Shourd was released Tuesday on $500,000 bail partially because of medical concerns, Iranian officials said. She reportedly is suffering from a serious gynecological condition and found a lump in her breast.
Shourd was scheduled to visit a doctor today for a medical examination on her first day of freedom from an Iranian prison, sources familiar with the situation told ABC News.
Swiss diplomats who represent U.S. interests in Iran warned Shourd's family last May that the 32-year-old woman was suffering from depression.
Public discussion of her release began on Sept. 9 after a lawyer for Shourd claimed he "warned" Iranian officials that her health was deteriating.
"I gave a letter to Tehran investigators, and I warned [them] about Sarah's situation, and that her health is very weak. They can hold them for up to a year for the investigation, but not more than a year if they haven't been given a proper trial," attorney Masoud Shafie told ABC News through a translator last week.
Earlier this month, Shourd's mother, along with the mothers of two other American hikers still currently detained in Iran, pleaded Iranian officials to release the hikers, saying she were "gravely concerned" for Shourd's health.
As Shourd receives medical attention today, the mothers of the other two captives made an impassioned plea directly to Iranian President Mahmoud Ahmadinejad to free their sons.
"Josh and Shane are still detained in Iran, as you well know," Laura Fattal said on "Good Morning America" of her son Josh Fattal and his friend, Shane Bauer, directly addressing Ahmadinejad. "We thank you for bringing Sarah home, but now it is time [to] bring Josh and Shane home. We urge you ... to show the same compassion you had for Sarah to bring Josh and Shane home."
"I was very happy for Sarah and her mom," Cindy Hicky, Bauer's mother, said. "But very sad that Shane wouldn't be coming with her. ... How hard it must have been for them to separate."
Bauer and Shourd became engaged while they were in captivity and broke the news to their parents in May during the only meeting the mothers and prisoners have had since their July 2009 arrests. They were captured while hiking near the relatively unmarked Iran-Iraq border after allegedly crossing into Iran. They have been accused of espionage.
Upon release, Shourd said she would do everything she could to secure her fiance's and friend's release.
"All of my efforts, starting today, are going to go into helping procure the same freedom for my fiance Shane Bauer and my friend Josh Fattal because I can't enjoy my freedom without them," she said Tuesday. "They should be standing here with me."
When she was released, Shourd thanked officials in Iran and singled out Ahmadinejad for the "humanitarian gesture." Fattal and Hicky also thanked Ahmadinejad for what they called his intervention in Shourd's case, and agreed with a State Department challenge for him to bring the two captives with him when Ahmadinejad comes to the United States for an upcoming United Nations presentation.
"We're always hopeful. ... I hope he really takes that to heart," Hicky said.
"It's their turn now," Fattal said.
