A chemical found in green tea has been used to treat two types of skin cancer, scientists say.
extract is too weak to make an impact when consumed in tea. However,
when applied to cancer cells in the lab it made two-thirds of tumours
shrink or disappear.
Scientists at the universities of Strathclyde and Glasgow, who carried out the research, found the extract, known as epigallocatechin gallate (EGCg), had no side-effects on other cells or tissue.
created a cell with EGCg and transferrin, a protein that naturally
targets and latches on to the surface of cancer cells, and applied it to
tumours. Tests were
done on two types of skin cancer: epidermoid carcinoma which forms
scales on the surface of the skin and melanoma which often develops in
people who have moles on their skin.
both studies, 40 per cent of tumours vanished, while 30 per cent of
tumours in carcinoma cases and 20 per cent in melanoma cases shrank. A
further 10 per cent of melanoma tumours were stabilised, so did not grow
10,000 people in the UK are diagnosed with melanoma each year, with the
majority women, according to the Macmillan Cancer Support charity.
