A woman's risk of developing breast cancer has
risen to one in eight from one in nine, according to Cancer Research UK.
The charity's figures show that breast cancer rates in the UK have increased by
3.5% in 10 years, from 42,400 new cases in 1999 to 47,700 in 2008.
Women aged between 50 and 69 have seen the biggest rise in breast cancer rates
Exercising and eating healthily can reduce the risk, cancer charities say.
Cancer Research UK figures suggest that breast cancer is by far the most common
cancer in women, accounting for almost a third of cases.
Bowel cancer is the second most common, followed by lung.
Almost half of breast cancer cases in 2008 (48%) were in women aged between 50
A third were in women aged over 70, with 19% in women aged 25-49.
Previous research has shown that lifestyle factors and a family history of
breast cancer increase a woman's risk of developing the disease.
Sara Hiom, director of health information at Cancer Research UK, said that small
changes in everyday habits can help to reduce cancer risk.
"Cutting back on alcohol by keeping within government recommended limits of no
more than 14 units a week (a small drink a day) helps.
"Taking more exercise and eating a diet high in fibre but low in saturated fat
can help maintain a healthy weight - which in turn reduces breast cancer risk."
New figures from the World Cancer Research Fund suggest that making these simple
changes in lifestyle could result in about 79,000 cases of all kinds of cancer
being prevented in the UK each year.
The WCRF says breast cancer cases specifically could be reduced by 42%.
Obesity most likely increases the risk of cancer by raising levels of hormones
such as oestrogen and insulin in the body. High levels of these hormones,
produced by the fat tissues, are common features of many cancers.
Excess body fat may also affect how the body processes fats and sugars and how
the immune system functions.
Almost two out of every three women with breast cancer survive for more than 20
years and more than three-quarters of women with breast cancer survive for at
least 10 years, says Cancer Research UK.
Sara Hiom, from Cancer Research UK, urged women to get tested at the earliest
"Mammograms will pick up breast cancers early on before they can be felt as a
lump or spotted through other visible changes and we know that the earlier a
cancer is detected the more successful treatment is likely to be, so women can
benefit by taking up invitations to breast screening," she said.
Dr Rachel Greig, senior policy officer at Breakthrough Breast Cancer, said the
figures were a wake-up call and should not be ignored.
"More women are developing breast cancer and, although survival is improving
thanks to breakthroughs in breast awareness, screening and treatment, we clearly
have much further to go.
