Lauren Ashley, 30, has has had more than 20 operations or minor procedures to identify and remove malignant growths.
She was first diagnosed with cancer in her lung as a toddler, but has since been struck three more times, in her left eye, her bladder and a kidney, and on her right foot.
Lauren said: "I must be the unluckiest person in Britain. Some people may think it's freaky but I just think it's part of me now. All I can do is carry on and not think about it too much."
Lauren, from Bedford, was 16 months old when she was diagnosed with neuroblastoma, which caused a tumour in one of her lungs.
The growth was removed just before her second birthday and she went on to have her daughter Eryn, now six.
But in 2008 Lauren's bad luck returned. She suffered a migraine that lasted for several days, and specialists eventually said there was a tumour behind her left eye, which they are still monitoring.
The following year, she was diagnosed with cancer for the third time, in her bladder and left kidney.
She had surgery to remove the tumours from her bladder, and to remove the kidney completely.
This July, the disease struck again when Lauren noticed a lump on her right foot, which was diagnosed as squamous cell carcinoma, a form of skin cancer, and was removed.
Doctors now think it might be connected to the cancer behind her eye, which they believe is a melanoma. Next week , she will begin another course of chemotherapy to shrink it.
