Teresa Kay is single and 25 years old. Two months ago, she was diagnosed with non-Hodgkin's lymphoma, a cancer of the lymph glands. Doctors calculate that, in her age group, there is a 50% chance of a cure if the cancer is treated conventionally.

When Janice Wheeler discovered a lump under her right jaw, she thought it was a blocked saliva gland. She ignored it, and it seemed to go away. One year later the lump reappeared and this time she went to her GP who referred her to hospital for a biopsy. The diagnosis of non-Hodgkin's lymphoma came as a shock to her but, unlike King Hussein of Jordan, who succumbed to the disease on Sunday after many attempts at treatment, two years after chemotherapy Janice remains well and free of disease.
