Oxygen-starved tumor cells have survival advantage that promotes cancer spread

Using cells from human breast cancers and mouse breast cancer models, researchers say they have significant new evidence that tumor cells exposed to low-oxygen conditions have an advantage when it comes to invading and surviving in the bloodstream.

Simple blood test for early detection of breast cancer

Breast cancer could be detected up to five years before there are any clinical signs of it, using a blood test that identifies the body's immune response to substances produced by tumor cells, according to new research.

New method identifies aggressive breast cancer

Aggressive forms of breast cancer often manipulate the immune response in their favor. This manipulation is revealed in humans by the same immunological 'signature' as in mice. This is shown by a new study. The method makes it possible to obtain an indication of the prognosis of the disease using patients' tumor tissue.

Attacking metastatic breast cancer with sound

Drugs can be safely delivered to cancerous lymph nodes via the lymphatic system and then released inside the nodes using sound waves. Researchers tested the treatment on mice with metastatic breast cancer.

Monitoring the corrosion of bioresorbable magnesium

Researchers have recently been able to monitor the corrosion of bioresorbable magnesium alloys at the nanoscale over a time scale of a few seconds to many hours. This is an important step towards accurately predicting how fast implants are resorbed by the body to enable the development of tailored materials for temporary implant applications.
