US Food and Drug Administration (FDA) has approved the cobas HPV (Human Papillomavirus) Test which identifies women at highest risk for developing cervical cancer. This test will help physicians make early, more accurate decisions about patient care, which may prevent many women from developing this deadly disease.

MIT engineers have developed carbon nanotubes into sensors for cancer drugs and other DNA-damaging agents inside living cells.
The sensors, made of carbon nanotubes wrapped in DNA, can detect chemotherapy drugs such as cisplatin as well as environmental toxins and free radicals that damage DNA. Continue reading “Nanotubes sniff out cancer agents in living cells”
The leading cause of death in all cancer patients continues to be the resistance of tumor cells to chemotherapy, a form of treatment in which chemicals are used to kill cells.
Now a study by UC Riverside biochemists that focuses on cancer cells reports that ingesting apigenin – a naturally occurring dietary agent found in vegetables and fruit – improves cancer cells’ response to chemotherapy.

Researchers have discovered a mechanism for the rapid growth seen in infantile hemangioma, the most common childhood tumor.
The tumors, which are made up of proliferating blood vessels, affect up to 10 percent of children of European descent, with girls more frequently afflicted than boys. The growths appear within days of birth—most often as a single, blood-red lump on the head or face—then grow rapidly in the ensuing months. The development of infantile hemangioma slows later in childhood, and most tumors disappear entirely by the end of puberty. However, while the tumors are benign, they can cause disfigurement or clinical complications. This new research offers hope for the most severe of these cases, pointing at a potential, non-invasive treatment for the condition.

Engineers from the California Institute of Technology (Caltech) have created a “plug-and-play” synthetic RNA device–a sort of eminently customizable biological computer–that is capable of taking in and responding to more than one biological or environmental signal at a time.
In the future, such devices could have a multitude of potential medical applications, including being used as sensors to sniff out tumor cells or determine when to turn modified genes on or off during cancer therapy.

Its already known that weight-loss surgery for morbid obesity can reduce the risk of diabetes and heart problems. Now, new research shows that it may also cut a persons risk of cancer by 80-percent.
A Northwestern University research team has developed a promising nanomaterial-based biomedical device that could be used to deliver chemotherapy drugs locally to sites where cancerous tumors have been surgically removed.
The flexible microfilm device, which resembles a piece of plastic wrap and can be customized easily into different shapes, has the potential to transform conventional treatment strategies and reduce patients’ unnecessary exposure to toxic drugs. The device takes advantage of nanodiamonds, an emergent technology, for sustained drug release. Continue reading “Nanodiamond drug device could transform cancer treatment”
