Legal & General paid out over £8.5 million to women who had been diagnosed with breast cancer in 2014.
The average age of someone making a claim for this illness was 49 years old.
Legal & General issued its claims statistics to support Breast Cancer Awareness month, which is taking place this October.
Breast cancer is the most common cause of cancer in women in the UK and can affect both men and women. Statistics published by Cancer Research UK found that in 2011 nearly 50,000 women were diagnosed with the disease, the equivalent of more than 130 women a day.
A woman in the UK has a one in eight chance of being diagnosed with breast cancer during her lifetime.
Mark Holweger, managing director, intermediated at Legal & General Assurance Society said:"Breast cancer is a huge issue for women in this country and Legal & General fully supports Breast Cancer Awareness Month. With over a 100 women being diagnosed each day it is really important that anyone who has any concerns speaks to their doctor as soon as possible.
"Breast cancer can be diagnosed in anyone, man or woman, young or old, so it is vital that everyone makes sure they are aware of the symptoms and takes steps to protect themselves."
