Nanoparticles deliver anticancer cluster bombs

Scientists have devised a triple-stage "cluster bomb" system for delivering the chemotherapy drug cisplatin, via tiny nanoparticles designed to break up when they reach a tumor.

Chemists cram two million nanorods into single cancer cell

( -- Rice University chemists have found a way to load more than 2 million tiny gold particles called nanorods into a single cancer cell. The breakthrough could speed development of cancer treatments that would ...

Crystal structure reveals how curcumin impairs cancer

Quantum entanglement: the 'spooky' science behind physics Nobel

This year's physics Nobel prize was awarded Tuesday to three men for their work on a phenomenon called quantum entanglement, which is so bizarre and unlikely that Albert Einstein was skeptical, famously calling it "spooky".

Performing cellular surgery with a laser-powered nanoblade

To study certain aspects of cells, researchers need the ability to take the innards out, manipulate them, and put them back. Options for this kind of work are limited, but researchers reporting May 10 in Cell Metabolism describe ...

Breast cancer

Breast cancer is a cancer that starts in the breast, usually in the inner lining of the milk ducts or lobules. There are different types of breast cancer, with different stages (spread), aggressiveness, and genetic makeup. With best treatment, 10-year disease-free survival varies from 98% to 10%. Treatment is selected from surgery, drugs (chemotherapy), and radiation. .

In the United States, there were 216,000 cases of invasive breast cancer and 40,000 deaths in 2004. Worldwide, breast cancer is the second most common type of cancer after lung cancer (10.4% of all cancer incidence, both sexes counted) and the fifth most common cause of cancer death. In 2004, breast cancer caused 519,000 deaths worldwide (7% of cancer deaths; almost 1% of all deaths).

Breast cancer is about 100 times as frequent among women as among men, but survival rates are equal in both sexes.
