Cancer News: HPV vaccine highly effective ♦ Nanohydrogels attack cancer cells ♦ Gold nanotubes attack cancer cells ♦ Hormone replacement therapy increased ovarian cancer

HPV vaccine highly effective against multiple cancer-causing strains According to a multinational clinical trial involving nearly 20,000 young women, the human papilloma virus vaccine, Cervarix, not only has the potential to prevent cervical cancer, but was effective against other common cancer-causing human papillomaviruses, aside from just the two HPV types, 16 and 18, which are responsible for about 70 percent of all cases. That effectiveness endured for the study's entire follow-up, of up to four years. Continue Reading
Nanohydrogels that attack cancer cells Hydrogels are materials that are commonly used in everyday objects such as contact lenses or diapers, in order to control humidity. However, chemical engineers have now developed a new technology based on thermosensitive nanoparticles (nanohydrogels) to use these materials in the field of biomedicine, as an alternative to achieve controlled release of anticancer drugs.

Gold nanotubes launch a three-pronged attack on cancer cells Scientists have shown that gold nanotubes have many applications in fighting cancer: internal nanoprobes for high-resolution imaging; drug delivery vehicles; and agents for destroying cancer cells Continue Reading
Short-term use of hormone replacement therapy associated with increased ovarian cancer risk Taking hormone replacement therapy (HRT) for menopause, even for just a few years, is associated with a significantly increased risk of developing the two most common types of ovarian cancer, according to a detailed re-analysis of all the available evidence Continue Reading
