New marker substance for cancer cells
Scientists from ETH Zurich have developed a new substance that enables certain tumour types to be rendered visible in high resolution using positron emission tomography. The so-called tracer has successfully been tested in mice. Now the researchers are planning clinical trials in humans.

MicroRNA Drives Both Cancer Onset and Metastasis
A mere 25 years ago, noncoding RNAs were considered nothing more than "background noise" in the overall genomic landscape. Now, two new studies reveal that one of these tiny noncoding molecules -- microRNA-22 -- plays an outsized role in two types of cancer.

Cancer-linked FAM190A gene found to regulate cell division
Johns Hopkins cancer scientists have discovered that a little-described gene known as FAM190A plays a subtle but critical role in regulating the normal cell division process known as mitosis, and the scientists' research suggests that mutations in the gene may contribute to commonly found chromosomal instability in cancer.

Gene That Controls Aggressiveness in Breast Cancer Cells Identified
In a discovery that sheds new light on the aggressiveness of certain breast cancers, Whitehead Institute researchers have identified a transcription factor, known as ZEB1, that is capable of converting non-aggressive basal-type cancer cells into highly malignant, tumor-forming cancer stem cells (CSCs). Intriguingly, luminal breast cancer cells, which are associated with a much better clinical prognosis, carry this gene in a state in which it seems to be permanently shut down.

Immune-Boosting Colorectal Cancer Drug Shows Promise
New data on an emerging treatment that aims to fight colorectal cancer by stimulating the immune system have been presented at the ESMO 15th World Congress on Gastrointestinal Cancer.

Cancer : la radiothérapie entre au bloc
Radiophysicienne à l'hôpital Saint-Louis, à Paris, Ramona Itti pousse la console de radiothérapie mobile jusqu'à l'ascenseur. Direction le deuxième étage. Il est près de midi, ce jour de mai. La météo en berne n'affecte guère le moral des troupes : dans la salle aveugle du bloc chirurgical, les murs ont été blindés par vingt centimètres de béton ; les portes, par une fine couche de plomb. Une sécurité imposée par la réglementation française, et dûment contrôlée par l'Autorité de sûreté nucléaire (ASN).

Cancer professionnel : la difficile question de la reconnaissance
D’après des chiffres parus en 2003, le travail aurait été responsable de 11.000 à 23.000 cancers en France. Tous ne sont cependant pas reconnus comme tel. La question de la causalité reste souvent délicate à déterminer. Mais pourquoi ?
