Examining the molecular profiles of tumors from 12 different types of cancers, scientists working with the National Institutes of Health-backed Cancer Genome Atlas said Thursday they had found striking similarities between tumors originating in different organs. Their discoveries, made possible by improvements in sequencing technologies and computing methods, could herald a day when cancers are treated based on their genetic profiles, rather than on their tissue of origin, said UC Santa Cruz biomolecular engineer Josh Stuart , a participant in the project and coauthor of a commentary discussing its findings released Thursday by the journal Nature Genetics . Eventually, such a shift in thinking could lead researchers to new treatments for hard-to-treat cancers, Stuart said, in an interview with the Los Angeles Times.

A two-step process that begins by looking for a sudden change in a cancer marker may hold the key to detecting ovarian cancer earlier in its development, when this often-lethal cancer is easier to treat successfully, says a new study published in the journal Cancer. The study used a growing body of research on ovarian cancer to devise a strategy to identify women who need more intensive monitoring and not raise alarms or increase invasive surgery among women who are not likely to have developed the disease.

Women, wouldn't you like to know your precise risk of developing breast cancer, ovarian cancer and endometrial cancer? And wouldn't you like to know what changes you could make in your life to reduce that risk? Researchers from the National Cancer Institute would like to help you. They've just published a study in the journal PLOS Medicine that takes a significant step toward that goal. Ruth Pfeiffer , a senior investigator in the National Cancer Institute's Division of Cancer Epidemiology and Genetics, and colleagues focused on the predictive value of more than a dozen variables, including a woman's body mass index , number of children she has, how long she took birth control pills, whether she used hormone therapy to treat symptoms of menopause, family history of gynecological cancers, and use of cigarettes and alcohol.

Pierce Brosnan 's daughter Charlotte has died of ovarian cancer, the same disease that took her mother, Cassandra Harris, in 1991. She was 41. "On June 28 at 2 p.m. my darling daughter Charlotte Emily passed on to eternal life, having succumbed to ovarian cancer," Brosnan , 60, said in a statement to People . She was surrounded by her husband, her two children and her two brothers. Charlotte had battled the disease for three years.

In the course of our country's history, the U.S. Patent and Trademark Office has bestowed coveted protection on many strange and wondrous inventions: the three-legged pantyhose (in case one leg runs), the sealed, circular peanut butter-and-jelly sandwich, the motorized ice cream cone. And of course, the human gene. The human gene? How is that even possible? Could you patent a cat's whiskers? A cloud formation? A comb-over for a balding man? (Ah, well, yes, there is a comb - over patent out there somewhere.)

WASHINGTON - The Supreme Court ruled that human genes are a product of nature and cannot be patented and held for profit, a decision that medical experts said will lead to more genetic testing for cancers and other diseases and to lower costs for patients. In a unanimous ruling Thursday, the nine justices declared that human genes are not an invention, so they cannot be claimed as a type of private property. The decision invalidates a Utah company's patents on two genes that are linked to breast and ovarian cancer, and is likely to lead to several thousand other gene patents being tossed as well.
