Breast implants: is there an association with connective tissue disease?

Area of Science:

• Biomaterials Science
• Immunology
• Rheumatology

Background:

• Concerns exist regarding a potential association between silicone gel breast implants and connective tissue diseases.
• The Medical Devices Directorate (MDD) of the Department of Health initiated a review of available data.

Purpose of the Study:

• To evaluate the scientific data concerning the safety of silicone gel breast implants.
• To assess the potential link between breast implants and connective tissue diseases, particularly scleroderma.

Main Methods:

• Comprehensive review of existing scientific literature and data.
• Analysis of animal studies investigating silicone's immunological effects.
• Examination of epidemiological data on scleroderma prevalence in women with breast implants.

Main Results:

• Animal studies indicate silicones are unlikely to provoke significant immune responses or impair infection resistance.
• While silicones can act as adjuvants, their effects are minimal unless with potent adjuvants.
• One patient series showed a higher scleroderma prevalence, but overall incidence in women with implants is not demonstrably higher than in the general population.

Conclusions:

• The available data does not establish a clear causal link between silicone gel breast implants and connective tissue diseases like scleroderma.
• Further investigation may be warranted, but current evidence does not support a widespread increased risk.
