One therapeutic dose of radiation causes 30 percent spongy bone loss in mice

...menopausal women who received pelvic radiation for cervical and colorectal cancer increased their bone fracture risk by 60%. Radiation following anal cancer increased the risk of fracture by 200%, he said. Astronauts lose 2% of bone mass for each month they are exposed to the effects of microgravity. So far...

Gene screen for breast cancer better than pathologist's 'eye'

...uch as lung, head and neck cancers, pancreatic and cervical cancers." Pathologists look for telltale shapes of cells to determine if cancer is present, but molecular changes in cells, especially for early cancers, are beyond the reach of even the most powerful microscopes.

Spinal cord bridge bypasses injury to restore mobility

...d animal study, 12 rats had spinal injuries at the cervical level 3 (C3) that resulted in impaired motor functions to their right side limbs. The animals had trouble moving, climbing or grooming.

Teens unaware of sexually transmitted diseases until they catch one, Carnegie Mellon study finds

...nital warts can render a woman more susceptible to cervical cancer, and chlamydia can lead to infertility. A 2004 study, involving the same group of adolescent girls, found that those who viewed an interactive sex education DVD created by Carnegie Mellon researchers were more likely to become abstinent than ...

Building a better mouse model of lung cancer: FHIT counts

... head and neck, esophageal, colorectal, breast and cervical cancers as well. Because the loss of FHIT occurs so early in lung cancer, mice that are missing that gene may be a good model in which to test new ways to treat or prevent the disease, says Huebner. "There are some other useful mouse models out ther...
