A large follow-up study of cosmetic breast implant patients previously suggested an overall decrease in mortality but increased risks of brain and respiratory cancers and of suicides.
This cohort of 12,144 implant patients and 3614 patients with other types of plastic surgeries was followed for 5 additional years, enabling derivations of standardized mortality ratios (SMRs) based on population rates and relative risks (RRs) based on comparisons with the other patients.
A total of 443 implant and 221 other plastic surgery patients were identified as deceased (SMR = 0.65 [95% confidence interval (CI) = 0.6-0.7] and 0.56 [0.5-0.6], respectively). Despite evidence that implants can interfere with mammographic visualization, there was no evidence that implant patients had a higher risk of death from breast cancer as compared with either the general population or other plastic surgery patients. The previous excess risk of brain cancer deaths among implant patients was attenuated by follow-up (as the result of no additional deaths; SMR = 1.43, 0.8-2.5; RR = 2.07, 0.5-8.9). A previously observed excess risk of respiratory cancer deaths persisted in comparisons with other plastic surgery patients (RR = 1.63; 1.0-2.7), but there was no evidence of a trend of risk with follow-up time. Implant patients also showed an elevated risk of suicide (SMR = 1.63, 1.1-2.3; RR = 2.58, 0.9-7.8) and of deaths caused by motor vehicle accidents (RR = 1.73; 0.6-5.4).
Although several elevations in cause-specific mortality were attenuated by additional follow-up, the excess risk of suicide among the implant patients remains of concern.

    • "Due to initial health concerns regarding silicone implants used for breast reconstruction and augmentation, there have been numerous epidemiological studies conducted to evaluate adverse outcomes. Several studies have reported a protective effect for breast cancer in women with silicone implants (Brinton et al., 2006; Brisson et al., 2006; Deapen et al., 2007; Friis et al., 2006; Lipworth et al., 2009; McLaughlin et al., 2006; Villeneuve et al., 2006). Two studies found a 30–50% reduction of risk in breast cancer with silicone augmentation (Brisson et al., 2006; Lipworth et al., 2009). "

    ABSTRACT: Silicone polymers are used for a wide array of applications from passive samplers in environmental studies, to implants used in human augmentation and reconstruction. If silicone sequesters toxicants throughout implantation, it may represent a history of exposure and potentially reduce the body burden of toxicants influencing the risk of adverse health outcomes such as breast cancer. Objectives of this research included identifying a wide variety of toxicants in human silicone implants, and measuring the in vivo absorption of contaminants into silicone and surrounding tissue in an animal model. In the first study, eight human breast implants were analyzed for over 1400 organic contaminants including consumer products, chemicals in commerce, and pesticides. A total of 14 compounds including pesticides such as trans-nonachlor (1.2-5.9ng/g) and p,p'-DDE (1.2-34ng/g) were identified in human implants, 13 of which have not been previously reported in silicone prostheses. In the second project, female ICR mice were implanted with silicone and dosed with p,p'-DDE and PCB118 by intraperitoneal injection. After nine days, silicone and adipose samples were collected, and all implants in dosed mice had p,p'-DDE and PCB118 present. Distribution ratios from silicone and surrounding tissue in mice compare well with similar studies, and were used to predict adipose concentrations in human tissue. Similarities between predicted and measured chemical concentrations in mice and humans suggest that silicone may be a reliable surrogate measure of persistent toxicants. More research is needed to identify the potential of silicone implants to refine the predictive quality of chemicals found in silicone implants.

    ABSTRACT: An understanding of the scope and nature of negative psychological complications resulting from plastic surgery is vital. This knowledge is essential to improve the complex interactions that patients experience as part of their surgical intervention. This is a national survey of patients' psychological complications reported by 312 board certified plastic surgical nurses. Perceived patient psychological complications were reported at a higher rate than perceived physical complications (p> .001), with peri-operative complications of anxiety and mild depression being most prevalent. Less frequent psychological complications included patient disappointment and severe depression. Not surprisingly, surgical site pain and nonspecific physical distress were the most frequent physical complications; sleep disturbance was common. Psychological complications occur at higher rates than do physical complications in plastic surgical practices. Patients with pre-existing psychological conditions are more at risk for peri-operative psychological complications. Nurses should be adequately prepared to screen, support, and coordinate psychological treatment for plastic surgery patients with the plastic surgeon.
