Research shows that breast cancer appears in black women at an earlier age that it does in white women.
On average, white women diagnosed at Hornerton University Hospital at Hackney in east London, were 67 years old.
The average age of black women diagnosed with breast cancer was 46, which indicates that the disease strikes black women at an earlier age.
It is possible that the two ethnic groups may differ biologically, according to Dr. Rebecca Bowen, who wrote the "Cancer Research UK" study for the British Journal of Cancer.
Dr. Bowen emphasized that the new information is important in order to make the black population more aware of the risk factors associated with breast cancer and to emphasize the importance of early screening and detection.
Every year, 44,000 women are diagnosed with breast cancer in the UK, making it the most prevalent form of cancer in the nation.
Breast cancer will strike one in nine women, and approximately 80 percent of the cases will occur in women over the age of 50.
