A new study shows the odds of surviving breast cancer are improved not only because treatments are more effective, but also as a result of smaller tumors.

Pouring over 25 years of cancer records nationwide, researchers conclude smaller tumor sizes account for 61 percent of the improvement in breast cancer survival

Scientists at the Vienna Medical University in Austria say varying tamoxifen therapy with a drug called anastrozole produces better results in older women past menopause, in the early stages of their breast cancer.

"Switching from tamoxifen to anastrozole after two years is more beneficial for the patients than staying on tamoxifen," Professor Raimund Jakesz, the lead researcher, says in an interview

Researchers at the University of Cambridge in England announce the discovery of four new genes believed to be involved in the development of breast cancer.

After examining tissue from 53 breast cancer tumors and cells grown in the laboratory, researchers narrowed down the search for the genes that could provide a foundation for new treatments of breast cancer

Researchers have finally been able to find out how much exercise women should perform for their age. They have also found that their ability to exercise is a little lower than men's, however, their ability to exercise decreases faster than men's.

The research reveals women whose capacity is under 85-percent of what it should be are likely to die within eight years

Researchers at the University of Cambridge in England have narrowed down the search for the genes that that could provide a basis for new treatments for the disease, according to a Reuters Health Report.

"By using the latest in DNA technology we've been able to pinpoint four new genes likely to be involved in the development of breast cancer," said Professor Carlos Caldas, who headed the research team
