News on Cancer

Cancer is a class of diseases in which a group of cells grow uncontrollably, invade and destroy adjacent tissues and sometimes spread to other locations in the body via lymph or blood (metastasize).  These three malignant properties differentiate them from benign tumors, which are self-limited, and do not invade or metastasize.  Most cancers form a tumor but some, like leukemia, do not.

Cancer can be the result of DNA mutations, exposure to carcinogens or radiation, viral infections, hormonal imbalances, immune system dysfunction or a hereditary predisposition to certain syndromes.

Update on Cell Phones and Brain Tumors

About 30 studies have tried to evaluate the possible association between cell phones and the risk of brain tumors, but the results have been inconsistent. Conclusions from the INTERPHONE project, the largest study ever conducted on the use of cell phones and cancer risk were published online in the International Journal of Epidemiology. Although the results have been eagerly anticipated, it seems that the link between cell phones and brain tumors is still in question. Read more

Preventing Lung Cancer in Smokers

As HealthandAge reported yesterday, a team of U.S. researchers has determined that a gene pathway called PI3K is activated in the airways of smokers with lung cancer and testing for PI3K activation may be a way to predict or diagnose lung cancer. According to this same study published April 7 in the journal Science Translational Medicine, treatment with an inexpensive and widely-available natural supplement may reverse PI3K pathway activation and help to prevent lung cancer in high-risk smokers.

Predicting Which Smokers Will Get Lung Cancer

Cigarette smoke is the leading cause of lung cancer in the United States, accounting for approximately 90 percent of all lung cancer cases. Unfortunately, at this time, there is no reliable test for predicting which smokers are at highest risk for developing lung cancer. It is also difficult to detect lung cancer at an early stage, when treatment might be more effective. Read more

Obese Patients Just as Likely to Receive Preventive Care

People who are overweight or obese often fear that healthcare providers are biased because of their weight. And, clinicians often express dissatisfaction in caring for obese patients. In combination, these observations raise potential concerns that obese patients might receive lower quality of medical care. However, according to a new study published in the April 7 issue of the Journal of the American Medical Association, obese patients are no less likely to receive recommended preventive care than other patients.

Which Prostate Cancer Treatment is Best for Quality of Life?

Robot-assisted procedures for prostate cancer are increasingly popular among patients, in part due to marketing from surgery centers and the perception that these types of surgeries are better than open radical procedures for prostate cancer. According to a new study in the Journal of Urology, men with early stage prostate cancer are likely to experience better long-term quality of life with non-surgical treatments. Read more

Laparoscopy No Better Than Open Surgery for Prostate Cancer

Open radical prostatectomy is considered the standard treatment for prostate cancer. However, minimally-invasive surgical procedures for prostate cancer are becoming more popular even though there is limited evidence that these surgeries result in better outcomes than open radical prostatectomy. In the April 2010 issue of Journal of Urology, researchers report that laparoscopic prostate cancer removal and open prostate cancer removal have similar rates of complications. Read more
