Looking tired and drained, the visibly upset 27-year-old broke down as she was met by a number of photographers and left the airport by a private exit.
The mother-of-two returned home for more tests and treatment after speaking to her doctor, her publicist said.
In an interview before the diagnosis, Goody had told a magazine that she was going to India because she needed to support her family with earnings from "Bigg Boss", the Indian version of the British reality show "Big Brother".
"I have to keep working to support my family. It's not an option to stop, " she told Reveal magazine.
"It's always difficult working away from home but I can't wait around for the doctors to find out what's wrong with me. I need to keep working."
"I know it sounds crazy and a lot of people will criticise me for it, but I have to pay the bills at the end of the day. And if I do face cancer, I need to make sure I can support the boys, " she added.
"I will worry for my beautiful boys if I get unwell. I live for them." Goody's contract with "Bigg Boss" was reportedly worth 100, 000 pounds.
Her publicist Max Clifford confirmed the cancer diagnosis Tuesday, saying: "Jade had some tests recently, then she went off to India to appear in the Indian Big Brother."
"We put the consultant in touch with the programme-maker in India and, because of the circumstances, [he] was allowed to speak to her and explain the results of her tests."
He said the consultant advised Goody to return to Britain straight away.
