Using a technique that causes telomere DNA to fluoresce under a microscope, the researchers scrutinized tissue samples in which some cells had a precancerous
With the HALO360 System, physicians can remove the Barrett's tissue before it has a chance to develop into cancer just as they would any other precancerous
condition found in the body.
As with the precancerous
colon polyp, it makes logical sense that if we can eliminate the Barrett's dysplasia completely and safely, we should do so in order to reduce the risk for developing cancer.
Pulmonologist Stephen Lam of the British Columbia Cancer Agency in Vancouver and his colleagues used a flexible, lighted scope to examine lung tissue and procure a sample of one precancerous
lesion from each of 101 current and past smokers around age 40.
Mediscience Technology Corporation and its New York subsidiary, Medi-photonics Development Company LLC, are engaged in the design, development and commercialization of medical devices that detect cancer and physiological change using frequencies of light that are emitted, scattered and absorbed to distinguish malignant, precancerous
, or benign tissues from normal tissues.
The microenvironment around a cancer-prone, or precancerous
, cell can either promote or suppress its growth into a tumor, adds Campisi.
We are pleased with the feedback regarding the ease of use and clinical performance of Onco-LIFE, especially for the detection of early cancer and precancerous
lesions where Onco-LIFE demonstrated a 325% per-lesion improvement in the detection of early lung cancer (moderate-severe dysplasia and carcinoma in situ) and a 250% per-patient improvement compared to white-light alone.
In addition, tests detected Cox-2 in precancerous
lesions in the stomachs of nine other volunteers.
According to the American Academy of Dermatology, around 10 million Americans each year are affected by actinic keratosis, or AK, a common type of precancerous
skin lesion caused by cumulative exposure to the sun.
Nine weeks later, they surveyed the rats for precancerous
intestinal-surface features called aberrant crypts.
The study results, presented at Digestive Disease Week(R) (DDW(R)), May 14-19, 2005, clearly demonstrate the benefits of the Halo360 system for the treatment of Barrett's esophagus, a precancerous
condition affecting the lining of the esophagus.
The difference between slightly abnormal tissue and precancerous
tissue can be subtle.
