Interleukin-1 beta (IL-1 beta)
Interleukin-1 beta (IL-1 beta) is similar in action to IL-1 alpha with the exception of its association with breast cancer. Immunoreactive IL-1 beta is detected in approximately 90% of invasive breast carcinomas. IL-1 beta levels are significantly higher in invasive carcinomas compared to benign lesions.
