‘America’s Sweetheart’ Julia Roberts has been alarmed ever since a mysterious mole showed up on the side of her right breast during a recent photo shoot.

photographers spotted the blemish as they snapped the Pretty Woman star at a Hollywood tribute to George Clooney and now cancer experts are calling for the actress to get screened.

After seeing photos of the actress’ mole Dr Christine Horner, a cancer expert and plastic surgeon in Taos, New Mexico, where Roberts has a home, told US tabloid the Globe that it would be better to remove the mole.

“I would definitely remove the mole. It is raised, pigmented and greater than a centimeter, which statistically increases the risk of it converting to malignancy,¡± he was quoted by Contactmusic, as saying.

But Beverly Hills dermatologist Dr David Stoll insists the blemish looks as if Roberts has already had a growth removed.

“It looks like a scar from the removal of a growth,” he added.
