Discovery of method to identify how cancer evades the immune system

One of the fundamental traits of a tumor - how it avoids the immune system - might become its greatest vulnerability, according to researchers from the University of Southern California. Their findings, demonstrated in human breast and colorectal cancers, indicate that a technique for determining a tumor's "immune signature," could be useful for diagnosing and treating specific cancers.

Long-term effects of cancer survivorship on the employment of older workers

Cancer survivors between 55 and 65 years old who remain cancer-free for two to six years after diagnosis are as likely to be working as their peers who have not had cancer, a new study shows. However, people recently diagnosed with new cancers are less likely to be working.

Exercise lowers insulin in breast cancer survivors

Normally sedentary breast cancer survivors who completed an exercise program reduced the levels of insulin in their blood, revealing a likely link between physical activity and better outcomes, researchers from Dana-Farber Cancer Institute in Boston reported at the annual meeting of the American Society of Clinical Oncology in Chicago.

Black Americans' beliefs may hamper lung cancer prevention and care

Blacks in the United States are less certain than whites about recommendations to prevent lung cancer and are more fearful of having symptoms evaluated, beliefs that may keep them from seeking timely treatment for the disease, researchers from Dana-Farber Cancer Institute reported at the American Society of Clinical Oncology's annual meeting in Chicago.

Two-photon absorption imaging of hemoglobin

In an advance that can potentially assist cancer diagnosis, a new optical technique provides high-resolution, three-dimensional images of blood vessels by taking advantage of the natural multiple-photon-absorbing properties of hemoglobin, the red-blood-cell molecule that carries oxygen throughout the bloodstream.
