Which condition is NOT considered a contraindication to breastfeeding?

Bilateral silicone breast implants are not a contraindication to breastfeeding. Multiple studies have shown that breastfeeding can be successfully achieved by women with breast implants, as silicone is contained within the implant and is not released into breast milk. Furthermore, the physical structure of the breasts is typically not altered to such an extent that it would impair the ability to breastfeed.

In contrast, maternal HIV infection is a significant concern for breastfeeding as the virus can be transmitted to the infant through breast milk. Active tuberculosis poses a similar risk where the disease could potentially infect the infant, especially if there is an active, untreated infection. Severe maternal drug abuse can also interfere with both the quality of breast milk and the mother's ability to care for the infant, leading to potential harm to the neonate.

Thus, while conditions like HIV and active tuberculosis are contraindications due to the risk of transmission of infectious agents, and severe maternal drug abuse can impact the health and wellbeing of both the mother and child, having bilateral silicone breast implants does not inherently pose the same risks to breastfeeding.
