Cancer Research: Antibody to save cancerous bones ♦ Better understanding of cancer-spreading enzymes ♦ Survival has improved for stage IV breast cancer

New studies create better understanding of cancer-spreading enzymes A detailed structural view of an enzyme, called MMP7, has been revealed as it binds to the membranes, or surfaces, of cancer cells. This understanding could lead to better treatments.
Survival has improved for women with stage IV breast cancer  study that included more than 20,000 women with stage IV breast cancer finds that survival has improved and is increasingly of prolonged duration, particularly for some women undergoing initial breast surgery.
Antibody developed to save cancerous bones Osteosarcoma (OS) is a rare cancer most often affecting adolescents and children. While most bone cancers have their origin in other body tissues and spread to the bones through metastases, OS originates in the bone tissue. Researchers now show that OS cells degrade the bone tissue through a completely different process than metastasized bone cancer. Through treatment with a specific antibody, the researchers blocked the process and reduced up to 80 percent of bone degradation in a cancer model
False-positive mammograms may indicate increased risk of breast cancer later Women with a history of a false-positive mammogram result may be at increased risk of developing breast cancer for up to 10 years after the false-positive result.
