Kelly Osbourne lives in fear she will one day be diagnosed with cancer and makes weekly visits to her doctor to get health shots to boost her immune system.
The singer-turned-reality TV star admits her mom Sharon’s battle with colon cancer in 2002 has scared her for life and she insists on regular check-ups.

She says, “I’m absolutely convinced I’m gonna get cancer. Once a week I go to the doctor and get a B12 shot; B12 is really good at building your immune system and keeping you healthy and every time I think I’ve got a lump somewhere, I’m like, ‘Oh my God, I gotta go to the doctor.’ Most of the time he sits me down and is like, ‘Kelly, get out of my office!'”

And the 26 year old reveals the cancer scare has taught her one important life lesson: “It makes you realize that, at the end of the day, all you have is your family.”

Rock matriarch Sharon Osbourne successfully battled the disease and went on to found her own cancer charity.
