premalignant lung cancer dna found by johns hopkins team


scientists from johns hopkins believe they have identified the very earliest premalignant genetic changes that mark the potential onset of the most common and deadliest form of lung cancer. researchers examined tissue, blood, and dna from six people with precancerous and cancerous lung lesions. the most destructive form of the disease is thought to develop from microscopic lesions in the lung tissue, which then becomes cancerous tumors by accumulating multiple genetic alterations. “this work is a big step in advancing our knowledge of lung cancer because it could give us a chance to find people at risk early,” says a member of the research team.

during the last few years, drug-resistant tb strains have grown more common. management of drug-resistant tb can be difficult, and these strains require specialized treatment. using conventional methods, patients with resistant tb would need to wait for up to six weeks for antibiotic resistance testing. with a new testing technique created by a university college london team, the detection time for tuberculosis (tb) may be reduced to a few days rather than a week or more.
