Breakthrough Breast Cancer is warning women of the dangers of alcohol.
The warning comes just two years after another major breast cancer charity adopted a wine company as a corporate sponsor.
A Breakthrough survey revealed only 7 per cent of women were aware of any link between alcohol and breast cancer and more than half of the total would either limit their consumption or stop drinking completely to reduce their risk.
"Drinking less alcohol is one of the few things women can do to reduce their risk," said Breakthrough chief executive Delyth Morgan.
Breast Cancer Campaign was criticised for accepting £50,000 in 2002 from wine company Hardy's.
The official relationship between the two companies has ended, but Claire Wakelin, PR manager for Constellation Europe, said staff continued to fundraise for Breast Cancer Campaign and had raised several hundred pounds during this year's awareness month.
