Coexisting cancer regimes: Transformations of breast and lung cancer in the United Kingdom.

Using in-depth interviews with medical professionals working in the UK, I explore the coexistence of two different cancer regimes in which the different innovations for breast and lung cancer can be located. Breast cancer treatment has seen a protracted series of significant innovations in the context of an emphasis on screening that coexists with a segmentation in subtypes that has allowed targeted therapies for most patients. Lung cancer has also seen the introduction of targeted therapies; however, these can only be used for small groups of patients. Consequently, some interviewees working on lung cancer have expressed a stronger focus on increasing the number of patients undergoing surgery, as well as introducing screening also for lung cancer. As a result, a cancer regime based on the promises of targeted therapies coexists with a more traditional approach that focuses on diagnosing and treating cancers in their early stages.
