A simple nail balm that could greatly improve the quality of life of cancer patients is being tested.
Formulated by Robert Thomas, a cancer doctor at Addenbrooke's Hospital in Cambridge, it contains natural oils and plant extracts believed to be offer protection against the ravages of chemotherapy.
Just as powerful cancer drugs can make hair fall out, they can also make nails fall off. Other symptoms include ridges, blackening and foul-smelling pus, leaving those affected by onycholysis too embarrassed to socialise or go to work.
Even simple tasks, such as picking up or cuddling their children, can be painful.
Professor Thomas said that overall, emotional toll is on a par with hair loss but it is largely ignored. Men and women are both affected, and taxotere - one of the most common, breast, prostate and lung cancer drugs - is the worst offender.
