Day surgery for brain tumours on the NHS in Britain

The technique, which has been developed by Britain's youngest female brain surgeon, Dr. Gelareh Zadeh at University College Hospital, London, "freezes" the patient's scalp with a local anaesthetic before making an incision in their skull.

Experts say the use of a local rather than general anaesthetic makes operating easier and means the patient makes a faster recovery; they can also go home the same day rather than remain in hospital for up to a week.

The procedure was first performed in July this year on 52-year-old patient, Deborah Calder, who remained awake throughout the surgery and was able to talk to her doctors throughout the operation.

Mrs Calder, who had cancer in her lungs before it spread to her brain, says the procedure was completely painless, and she was made to feel very relaxed; the operation has apparently given her "a new lease of life".

By evening she was at home with her family enjoying a cup of tea and has since made a full recovery.

As a rule a brain tumour is a very serious condition, and people require a great deal of support both before and after the operation.

The new technique has been described as potentially "very exciting" as it is less invasive than the usual surgery and the recovery period is much shorter.

The less time spent in hospital also lessens the likelihood of contracting an infection.

However, doctors say not all patients would be suitable for the treatment and also say there are downsides to going home so quickly and some might become anxious after the procedure about symptoms and not having access to the information they need at a crucial time.
