Breath Analysis Offers Non-Invasive Method to Detect Early Lung Cancer

"Researchers are using breath analysis to detect the presence of lung cancer. Preliminary data indicate that this promising noninvasive tool offers the sensitivity of PET scanning, and has almost twice the specificity of PET for distinguishing patients with benign lung disease from those with early stage cancer."

DNA Shed by Tumors Shows Promise for Non-Invasive Screening and Prognosis

DNA Shed by Tumors Shows Promise for Non-Invasive Screening and Prognosis | Lung Cancer Dispatch | Scoop.it

"Certain fragments of DNA shed by tumors into the bloodstream can potentially be used to non-invasively screen for early-stage cancers, monitor responses to treatment and help explain why some cancers are resistant to therapies, according to results of an international study led by Johns Hopkins Kimmel Cancer Center investigators.


"Analyzing blood samples from 640 patients with various cancers, the researchers used digital polymerase chain reaction-based technology (a sophisticated method of multiplying and measuring the number DNA molecules) to evaluate how well the DNA fragments predicted the presence of tumors in the patients."

Sidestepping the Biopsy With New Tools to Spot Cancer

Sidestepping the Biopsy With New Tools to Spot Cancer | Lung Cancer Dispatch | Scoop.it

"For people with cancer or suspected cancer, the biopsy is a necessary evil — an uncomfortable and somewhat risky procedure to extract tissue for diagnosis or analysis.


"Lynn Lewis, a breast cancer patient in Brooklyn, has had her cancer analyzed an easier way: simple blood tests that are being called 'liquid biopsies.'


"Telltale traces of a tumor are often present in the blood. These traces — either intact cancer cells or fragments of tumor DNA — are present in minuscule amounts, but numerous companies are now coming to market with sophisticated tests that can detect and analyze them."
