Immunity to commensal papillomaviruses protects against skin cancer
A mouse model of papillomavirus infection reveals that skin colonization with commensal papillomaviruses protects the immunocompetent host against chemical- and UV-induced skin cancer through CD8+ T cell immunity.

Palmitoylation-dependent activation of MC1R prevents melanomagenesis
The protein modification palmitoylation increases the ability of variant forms of the melanocortin-1 receptor (MC1R) to induce pigmentation, and this is linked to reduced development of melanomas.

Substantial contribution of extrinsic risk factors to cancer development
Recent analyses have suggested that the intrinsic behaviour of tissue stem cells may be responsible for malignant transformation and cancer progression, raising questions regarding the influence of extrinsic factors on tumourigenesis; here, both data-driven and model-driven evidence show that such intrinsic risk factors contribute only marginally to cancer development, indicating that cancer risk is heavily influenced by extrinsic factors.

An ultraviolet-radiation-independent pathway to melanoma carcinogenesis in the red hair/fair skin background
Individuals with the red hair/fair skin phenotype usually carry a polymorphism in the gene encoding the melanocortin 1 receptor (Mc1r) that results in the production of pigment containing a high pheomelanin-to-eumelanin ratio; here it is shown in a mouse model that inactivation of Mc1r promotes melanoma formation in the presence of the Braf oncogene, thus suggesting that pheomelanin synthesis is carcinogenic by an ultraviolet-radiation-independent mechanism.

Cyclin D1 multitasks
Cyclin D1 is one of the drivers of the cell cycle, and its deregulation may promote the development of tumours. Surprisingly, this protein also mediates the repair of damaged DNA, a mechanism that commonly prevents cancer. See Letter p.230

Introduction: The prevention agenda
Despite our relative wealth of knowledge about the causes of cancer, the disease persists — and the burden is worsening. Prevention demands political will, ample funding and a change in mindset.

Genomic evolution of metastasis
Prognosis for patients with pancreatic cancer is bleak, often owing to late diagnosis. The estimate that at least 15 years pass from tumour initiation to malignancy offers hope for early detection and prevention. See Letters p.1109 & p.1114
