Cancer patient recovers after injection of immune cells
By Roger Highfield, Science Editor

A cancer patient has made a full recovery after being injected with billions of his own immune cells in the first case of its kind, doctors have disclosed.

The 52-year-old, who was suffering from advanced skin cancer, was free from tumors within eight weeks of undergoing the procedure.

After two years he is still free from the disease which had spread to his lymph nodes and one of his lungs.

Doctors took cells from the man's own defense system that were found to attack the cancer cells best, cloned them and injected back into his body, in a process known as "immunotherapy". After two years he is still free from the disease which had spread to his lymph nodes and one of his lungs.

Experts said that the case could mark a landmark in the treatment of cancer.
