The researchers say this technology is both easier and more cost-effective than the more invasive treatments commonly used. It’s potential use is particularly promising in brain cancer victims due to its non-invasive nature, the laser’s ability to go through thin bone like the skull, and the femtosecond laser radiation which according to Parigger helps, “avoid heating up too many other things that you do not want heated.
” Now that the technology has been developed, Parigger and his colleagues are in the process of commercializing it and making it widely available.

Trials of galeterone record early success in treatment of advanced stage tumours...
A new drug that tackles advanced prostate cancer in three different ways has passed its first hurdle towards being approved.
Scientists reported promising early trial results using galeterone, which is designed to treat cancer that no longer responds to hormone therapy. However, researchers counselled caution as tests on the "triple whammy" drug have been carried out on only a small number of patients.
In their tests, scientists based at Harvard University reported that galeterone reduced levels of prostate specific antigen (PSA), a prostate cancer blood marker, by 30% or more in about half of patients. Eleven patients had PSA reductions of 50% or more, and in some there was significant shrinkage in tumour size.

The second annual Google Science Fair, a science talent competition for kids ages 13 to 18, was held this month in Palo Alto, California. This year’s winner, 17-year-old Brittany Wenger, wrote a cloud-based computer program that makes breast cancer detection less invasive. She called it the “Global Neural Network Cloud Service for Breast Cancer.” Wenger created computer programs coded to think like the human brain and then used them to locate mass malignancy in breast tissue samples.
BLOG: Engineered Viruses Could Kill Cancer
Traditional methods of finding mass malignancy use a minimally invasive, but painful, biopsy called a fine needle aspirate (FNA). Analyzing tissues collected with this method isn’t always effective and sometimes results in further invasive procedures. Wegner tested her method with 7.6 million trials to see how accurately it would detect cancerous tumors. It succeeded with a 97.4 percent success rate in prediction and 99.1 percent sensitivity to malignancy when analyzing samples collected from FNA. Employing this data to a cloud service could make it possible for doctors to assess tumors without employing more invasive testing.

Mina Bissell est venue partager ses 35 ans recherche sur le cancer, 35 années de travail autour d'une même question : qu’est-ce qui fait que les cancers se développent ? Sa réponse : leurs interactions avec leur micro-environnement. Elle n'a pas été la première à en avoir l'intuition mais la première à le prouver. A la conférence TEDGlobal, elle a raconté son expérimentation.

À la veille de la Journée mondiale contre le cancer, l'information est encourageante : une fibre optique portable dotée d’un scanner pourrait détecter en quelques minutes des cellules cancéreuses noyées au milieu du tissu sain.
Grâce à cette technique, les chirurgiens espèrent disposer de moyens suffisants pour s'assurer lors de l’excision d’une tumeur que tout le tissu cancéreux a bien été retiré et ainsi éviter les récidives.

The $100,000 Zhang earned comes with first prize in the Siemens Competition in Math, Science & Technology. Her project, “Design of Image-guided, Photo-thermal Controlled Drug Releasing Multifunctional Nanosystem for the Treatment of Cancer Stem Cells,” was apparently as complex, thorough, and revolutionary as it sounds.
The nanoparticle Zhang created is already being referred to as something of a “swiss army knife” in the area of cancer treatment. That’s not to say it’s dull and rusty because I you didn’t take care of it when I was you were out camping, but rather that it has a whole bunch of useful applications.
The nanoparticle is delivered to tumors via the drug salinomycin where it kills cancer cells and deposits gold and iron-oxide materials to help with MRI imaging.
