New scalpel probes into cancer

...inguish between normal human brain cells and their malignant form. At present the only way to tell if cancerous cells are present is to stain tissue samples, which may take hours this scalpel will be able to tell the surgeon when to stop cutting. The brain is a particularly critical place to know when enough...

Skin cancer on the rise

...erts say women have previously had higher rates of malignant skin cancer, probably because of the fashion for suntans. But now they are starting to listen to the warnings about skin cancer, and are protecting both themselves and their children....

Combined scan gives exact cancer diagnosis

...s not always possible to detect the border between malignant and normal areas. Doctors at the University of Texas now say that combining positron emission tomography (PET) with the more conventional computed tomography (CT) scan gives a more detailed diagnosis of such tumours. In PET, abnormal tissue is dete...

Reduction in melanoma death rate

Camera gives hope for detection of breast cancer

...intimammography, is good at distinguishing between malignant and benign tumours, has been done on a standard gamma camera. The limitation of this kind of camera is that it cannot pick up small tumours within dense breast tissue. The Hopkins team has designed a new, breast specific, camera that overcomes thes...

New surgery in head and neck cancer

...uency ablation involves the use of heat to destroy malignant tissue. Including liver tumours, it has been used to effect in varied tumour types.Now researchers at Montefiore Medical Center, New York, report// the primary use of radiofrequency ablation in head and neck cancer. The group of patients were not can...

Associated therapy for multiple myeloma

...intravenous administration. Multiple myeloma is a malignant cancer of the plasma cell, which is a type of white blood cell found in many tissues of the body. As the cancer grows, it destroys normal bone tissue, which causes pain and crowds out normal cell production. Multiple myeloma is the second most commo...

Implication of virus in colon cancer
