Anecdotal reports have suggested that silicone breast implants may cause immunological disorders. In a nationwide study of over 7000 Swedish women with breast implants and a control group of over 3000 who had undergone breast reduction surgery, Nyrén et al (p 417) found no excess risk for connective tissue disease. Among the women with implants, 29 were hospitalised for connective tissue disease compared with the 25.5 expected from national hospital discharge rates. Among the women who underwent breast reduction, the figures were 14 and 10.5 respectively. When the two groups of women were compared directly those with implants had a slightly lower risk of connective tissue disease.
