Newly created cancer stem cells could aid breast cancer research
...nitial experiments, a few tissue slices revealed a primary
tumor structure that resembled that of cancer patients with metastases. That prompted Ince to wonder whether the cancer cells he created would metastasize if the mouse lived longer. He repeated the experiment in other mice, reducing the number of c...

ways of treating cancer at present, and these have fundamentally changed little in 30 years. In the case of solid tumours, surgery can be used to cut out the cancerous tissue, while radiation therapy can kill the malignant cells, and chemotherapy sto...

New test improves detection of liver cancer
...patocellular carcinoma (HCC) is the most prevalent primary
liver cancer. The disease most often appears following a chronic inflammation of the liver as a consequence of a hepatitis B or C virus infection or cirrhosis of the liver. Cirrhosis of the liver comprises a group of liver diseases in which the norma...
