Breast Cancer Care is drawing up a campaign to make older women more aware of the risks of getting the disease.
The awareness drive, scheduled for October, follows a new report by the charity which highlights the concerns of 50 cancer specialists about older women, commonly perceived to be at less risk from breast cancer.
The report, Breast Cancer in the UK: What's the Prognosis?, shows that more than half the experts questioned believe there will not be enough cancer treatment facilities to cope with the ageing population in the next 30 years.
"Many women over 75 don't realise they are at risk," said Anna Wood, the charity's policy analyst. "But they are actually more likely to get breast cancer because the risk escalates as they age."
