Women who have breast implants and go on to develop breast cancer have a greater risk of dying from the disease than those without, a new study suggests.
Researchers say that patients with cosmetic implants have a 38% higher risk of dying from breast cancer than women who do not have implants.
The study, published on the British Medical Journal’s website, also found that women with implants could be diagnosed with breast cancer at a later stage than those without.
Previous research has suggested that implants can make it more difficult to detect cancer at an early stage because they can create shadows on mammograms that obscure breast tissue.
The authors, based in Canada, examined data from 12 studies relating to the stage at which breast cancer is diagnosed in patients with and without breast augmentation.
They found that women with cosmetic breast implants had a 26% increased risk of being diagnosed at a later stage of cancer than women without implants.
They also looked at a further five studies and found that women with implants had a 38% greater risk of death from breast cancer.
However, the authors stressed that the findings should be treated with caution because some of the studies did not adjust for other variables.
They called for further investigations into the long-term health effects of breast implants.
A statement released by the authors said: “The results show a higher risk of breast cancer-specific mortality among women with breast cancer who have implants compared with women with breast cancer without implants.
“Nevertheless, the overall estimate should still be interpreted with caution because this meta-analysis included a relatively small number of studies.”
Fazel Fatah, president of the British Association of Aesthetic Plastic Surgeons, said: “As the authors themselves conclude, the results of this statistical analysis of previously published papers should be treated with caution.
“The study only demonstrates an association of reduced survival rate from non-localised (advanced) breast cancer in women with breast implants rather than a cause.
“Further studies are required to see if other forms of breast scanning, such as MRI, could be preferable to mammography in women who have breast implants.”
