Breast cancer is the most common type of cancer in the UK. Most women diagnosed with breast cancer are over 50, but younger women can also get breast cancer.
About one in eight women are diagnosed with breast cancer during their lifetime. There's a good chance of recovery if it's detected in its early stages.
For this reason, it's vital that women check their breasts regularly for any changes and always get any changes examined by their GP.

Symptoms of breast cancer

a lump or swelling in either of your armpits
dimpling on the skin of your breasts

Being overweight may not be as unhealthy as it was 40 years ago," BBC News reports. New research has found a body mass index (BMI) of 27 is linked to the lowest rate of death – but someone with a BMI of 27 is currently classed as being overweight. BMI is a score calculated by dividing your weight (usually in kilograms) by the square of your height (usually in metres and centimetres). Currently, a BMI of 25 to 29.9 is classified as being overweight. Researchers looked at 120,528 people from Copenhagen, recruited from 1976 to 2013, and separately compared those recruited during the 1970s, 1990s and 2000s. They were followed up until they died, emigrated, or the study finished. The BMI linked to the lowest risk of having died from any cause was 23.7 in the 1970s group, 24.6 in the 1990s group, and had further risen to 27 in the 2003-13 group. It may be the case that the suggested upward shift in optimal BMI is the result of improvements in preventative treatments for weight-rela...
