On LostEdit

X-ray of Ben's spine in ("Every Man for Himself").

BenEdit

In "Every Man for Himself", Jack, while in a medical area of The Hydra, saw an X-ray of a man in his 40s with a large tumor on his spine.

This was revealed in "The Cost of Living" to belong to Ben, who said that he wanted Jack to operate on him. Though it was not stated whether it was a malignant or benign tumor, Ben implied that he would not have much time to live if something was not done.

• Jack eventually told Ben that it was malignant.

Later, Jack agreed to operate on Ben, in exchange for Kate and Sawyer being set free. He eventually removed the tumor, though the stitches later became infected. It is not yet known whether Ben returned to full health following the deal Jack made with him, which commuted Juliet's sentence so she would not be executed.

RachelEdit

Rachel had cancer and was going through chemotherapy. Her sister Juliet gave her medicine that allowed her to become pregnant. ("Not in Portland")

When Juliet was on the Island, Ben told her that the cancer had returned, but Jacob could heal Rachel if Juliet stayed on the Island to help the pregnant women. When Ben got cancer later, Juliet thought that Ben was lying and that Rachel was dead, but he proved to her that she was alive by showing her a live feed of Rachel with her son. ("One of Us")

MiscellaneousEdit

• Rose was diagnosed with some sort of terminal illness prior to coming to the Island (not specified, but likely cancer). It was deemed untreatable at that point, and she sought the advice of a spiritual healer. Miraculously, upon arrival to the Island, the disease seemed to have undergone spontaneous remission.
• Diane Janssen had a terminal illness and was being treated for it.
• Angelo Busoni had a terminal tumor that Jack unsuccessfully operated on. ("The Hunting Party")
• While being examined because of headaches, Sawyer told Jack that his uncle died of a brain tumor. ("Deus Ex Machina")
