A study of more than 15,000 childhood cancer survivors found a “surprisingly” high number lacked concern for their well-being in adulthood—despite the group’s increased health risks. Some 40 percent were unconcerned about developing new cancers.

Valerie Powell, a program coordinator with the University of Alabama at Birmingham’s department of radiation oncology struggled for eight years trying to figure out why a lump had formed under her jawline, with little help from CT and MRI.

“This study provides strong support that vitamin D plays an important role in breast cancer prevention,” said co-author of the study Joan M. Lappe, PhD, in a statement. “It also demonstrates that blood levels of vitamin D for breast cancer prevention need to be higher than currently recommended levels for bone health.”

"Our findings show that people have a strong desire to do something to address the threat of cancer and that they would prefer to receive a screening test that does not save lives rather than not be screened at all," said lead author Laura Scherer, PhD.

Researchers from the University of Michigan Rogel Cancer Center have discovered a new subtype of prostate cancer that occurs in about 7 percent of patients.

Several aspects of cancer-related cognitive impairment are currently unknown, including why it occurs, how long it lasts and what other health problems it causes. But the real mystery lies in the wide-ranging estimates of how many cancer patients “chemobrain” actually impacts, according to an article in the Los Angeles Times.

A multicenter clinical trial underway at UT Southwestern in Dallas is testing a new technique that would avoid nerve bundles and arteries commonly affected during prostate cancer radiation therapy in hopes of preserving patients’ sexual function.

Cancer researchers are taking notice of a pair of studies published in Nature Medicine that found editing a cell’s genomes with CRISPR-Cas9 has the potential to seed cancer and may eventually generate the disease, STAT reports.
