Tissue structure delays cancer development
Cancer growth normally follows a lengthy period of development. Over the course of time, genetic mutations often accumulate in cells, leading first to pre-cancerous conditions and ultimately to tumour growth. Using a mathematical ...

Comprehensive look at rare leukemia finds relatively few genetic changes launch disease
The most comprehensive analysis yet of the genome of childhood acute myeloid leukemia (AML) found only a few mistakes in the genetic blueprint, suggesting the cancer arises from just a handful of missteps, according to new ...

When inflexibility is counterproductive: Mechanism of UV-induced DNA Dewar lesion revealed
Excessive exposure to ultraviolet (UV) radiation of sunlight can result in skin damage and may even induce skin cancers. Irradiation with UV light causes mutations in the DNA, which can interfere with or even inhibit the ...

Researchers identify early ovarian cancers
Ovarian cancer kills nearly 15,000 women in the United States each year, and fewer than half of the women diagnosed with the disease survive five years. A screening test that detects ovarian cancer early, when it is still ...
