New information presented at the 69th Conference of the American Academy of Dermatology showed that skin cancer cases are rising dramatically in the U.S. The new estimates indicate that in 2006, the actual number of skin cancer cases was over 3.5 million. The authors suggest that the… more
A new report from the American Cancer Society on cancer in African Americans (AA) shows that the gap in survival between AA and Whiltes has decreased for cancers of the lungs and prostate but remained the same or increased for other cancers, including breast and colorectal. The differnces are… more
Accurate and early diagnoses is invaluable in the fight against cancer. Early detection guarantees the best chances of survival, since physicians can begin treatment before the cancer has had time to spread to other parts of the body. Researchers at the Fraunhofer Institute for Cell Therapy and… more
When the International Olympic Committee announced Beijing as the site of the 2008 summer Olympic games, more than a few eyebrows were raised. China had earned a reputation for its excessive air pollution, and athletes openly voiced concerns that the breathing conditions could hamper their… more
The level of circulating DNA in a cancer patient may positively correlate with the likelihood of the cancer to spread, report researchers from the Polytechnic University of Valencia. They describe the study from which they drew this conclusion in an article in the Journal of Thoracic Oncology. The… more
Glomas are a dfficult-to-treat form of brain cancer. Researchers at institutions in Texas have shown that they can target gold nanoparticles to gliomas implanted in mice. Nanoparticles are extremely small and can easily float in the blood and reach tumors. The nanopartilcles can then be… more
A review of patients enrolled in 16 clinical trials has revealed that the anti-angiogenesis drug bevacizumab (Avastin®) may actually increase the risk of death when combined with certain chemotherapy drugs. In combination with taxanes or platinum containing drugs, bevacizumab was associated… more
Many cases of stomach (gastric) cancer are caused by long-term infection with the bacterium Helicobacter pylori. A vaccine that prevents infection with H. pylori could reduce the incidence of gastric cancer. U.S. researchers, using computer modeling, have developed a vaccine that… more
Ovarian cancer is the most fatal gynecological cancer, in part because when the cancer is detected, the malignant cells have frequently already spread (metastasized) to other parts of the body, . Researchers at the Georgia Institute of Technology, however, have discovered that members of the miR200… more
Thrombin is a naturally occurring protein responsible for the clotting of blood in normal tissue. High levels of thrombin in cancer patients, however, are correlated with serious health threats. When the body is under stress, it triggers an inflammatory response, which signals the body to increase… more
In order for cancers to metastasize (spread to other parts of the body,) they often take advantage of the body’s normal signaling pathways. The Notch-signally pathway is very important in embryonic development, but its aberrant activity has been linked to tumor development. Researchers at… more
The blood-brain barrier (BBB) is a tight seal that prevents most things from crossing over from blood vessels into the fluid surrounding our brains and spine. Although this unusually restrictive system works to prevent bacteria, and other large and/or hydrophilic molecules, from diffusing into the… more
Cancer spread (metastasis) is responsible for about 90% of cancer deaths so knowing which cancers are likely to spread is very important. Researchers in China, Canada and the U.S. have discovered that levels of a single protein allowed them to make predictions of cancer spread with 90%… more
Japanese researchers have confirmed that dogs are able to very accurately detect colon cancer, even at early stages. The researchers let the dogs sniff stool or breath samples of cancer patients, normal patients and individuals with non-cancerous conditions of the colon (i.e. diverticulitis… more
Having surgery is stressful and it is well known that high stress levels can negatively affect the immune system. Researchers at MD Anderson have shown that patients taught stress management can boost their immune system function. The patients were all men who were going to have… more
Normal, healthy cells use specific proteins called transcription factors to regulate the activit of their genes. Importantly this is done in a tightly controlled manner. When the transcription factor NF-κB is functioning normally, it is capable of being turned off and on, and thus cellular… more
There's a reason your mom was so insistent you eat your broccoli. Among other things, broccoli has repeatedly shown its potential to fight off the development of cancer. This effect is accomplished, at least in part, by the enzyme myrosinase and the anti-inflammatory effects of a chemical found in… more
Broccoli is a special vegetable. Besides being packed with vitamins, it has repeatedly shown a capacity to fight off cancer. Until recently, why broccoli had this effect remained unknown. A recent study in the American Cancer Society's Journal of Medicinal Chemistry reveals that isothiocyanates (… more
The development of a model of the breast ductal system on a microchip represents a major step forward in breast cancer research. The “ breast-on-a-chip” model allows researchers to more accurately see the interaction that breast cancer therapies have with their environment, and how these affect… more
Human Immunodeficiency Virus (HIV) causes severe repression of the body’s capacity to heal and fight off infection. As a result, HIV patients are at a greater risk for developing some cancers. For HIV positive patient, physicians must pay special attention to their cancer treatment, since… more
