Breast Cancer Deaths Record Low
The number of women dying from breast cancer has fallen to a record low by dropping under 12,000 a
year for the first time since records began.
The Cancer Research UK data showed that 11,990 women died in the UK in 2007.
The previous lowest figure had been recorded in 1 97 1一 the year records began一after which it rose
steadily year by year until the late 1980s.
Professor Peter Johnson,Cancer Research UK's chief clinician,said,"It's incredibly encouraging to see fewer
women dying from breast cancer now than at any time in the last 40 years,despite breast cancer being diagnosed
more often."
"Research has played a crucial role in this progress,leading to improved treatments and better management
for women with the disease."
" The introduction of the NHS(国民保健制度)breast screening program has also contributed as the
earlier cancer is diagnosed,women are more likely to survive."
Breast cancer is now the most common cancer in the UK with 45,500 women every year diagnosed with
the disease一a 50% rise in 25 years.
The number of deaths peaked in 1989,when 15,625 women died.It then fell by between 200 and 400
deaths each year until 2004.
There was a slight rise in 2005 and then two years of falls.
Dr. Sarah Cant,policy manager at Breakthrough Breast Cancer,said,"It is great news that fewer women
are dying from breast cancer and highlights the impact of improved treatments,breast screening and
awareness of the disease."
"However,there are still too many women affected and the incidence of the disease is increasing year by
year.,,
The rising rate of breast cancer diagnosis has been put down to a variety of factors including obesity
(肥胖)and alcohol consumption.
Breast cancer can come back 10 years after you are first diagnosed.
