As breast cancer awareness month is observed during October, the American Physical Therapy Association (APTA) is hoping to shine a spotlight on lymphedema, a chronic, debilitating and often irreversible side effect of cancer treatment. http://www.physorg.com/news174846489.html Medicine & Health Thu, 15 Oct 2009 17:28:54 EST news174846489 A new report finds widespread variations and frequent errors in HER2 testing -- a procedure recommended for all patients with invasive breast cancer. http://www.physorg.com/news174760517.html Medicine & Health Wed, 14 Oct 2009 18:10:01 EST news174760517 Aromatase inhibitors, the same drugs that have buoyed long-term survival rates among breast cancer patients, also carry side effects including joint pain so severe that many patients discontinue these lifesaving medicines. New University of Pennsylvania School of Medicine research, however, has uncovered patterns that may help clinicians identify and help women at risk of these symptoms sooner in order to increase their chances of sticking with their treatment regimen. http://www.physorg.com/news173356992.html Medicine & Health Mon, 28 Sep 2009 11:43:54 EST news173356992 Men who have a regular, ongoing relationship with a health care provider are more likely to receive prostate cancer screening and less likely to be diagnosed with advanced prostate cancer, regardless of their race, according to a University of North Carolina study published in the current issue of the journal Cancer. http://www.physorg.com/news168075191.html Medicine & Health Wed, 29 Jul 2009 09:00:01 EST news168075191 For the 29,000 patients in the United States with metastatic colorectal cancer, chemotherapy with irinotecan is a standard treatment that has been shown to improve survival. But for more than one in 10 of these patients, a variation in their DNA means that this treatment could result in a severe reduction in their white blood cell count, leading to a high risk of bacterial infection and possible subsequent death. A new genetic test can identify those with the variation in order to lower the treatment dose -- however, it has been unclear whether the testing is worthwhile. http://www.physorg.com/news167911053.html Medicine & Health Mon, 27 Jul 2009 10:57:58 EST news167911053 For a human cell, this is a scary world. Each of the 60 trillion or so cells in the average person's body is damaged tens of thousands, perhaps a million, times a day, scientists say. http://www.physorg.com/news165692290.html Medicine & Health Thu, 02 Jul 2009 01:10:01 EST news165692290 By targeting and disabling a protein frequently found in melanoma tumors, doctors may be able to make the cancer more vulnerable to chemotherapy, according to early results of a clinical study conducted by researchers in the Duke Comprehensive Cancer Center. http://www.physorg.com/news155559442.html Medicine & Health Fri, 06 Mar 2009 10:58:10 EST news155559442 Frequent and/or long-term marijuana use may significantly increase a man's risk of developing the most aggressive type of testicular cancer, according to a study by researchers at Fred Hutchinson Cancer Research Center. The study results were published online Feb. 9 in the journal Cancer. http://www.physorg.com/news153373750.html Medicine & Health Mon, 09 Feb 2009 03:49:37 EST news153373750 Survivors of early-stage lung cancer who take part in regular physical activity have a better quality of life, according to a study in the February issue of the journal Cancer Epidemiology Biomarkers and Prevention, available online now. Patients who are more physically active report better mood, more vigor, and greater physical functioning, the study shows. http://www.physorg.com/news152892495.html Medicine & Health Tue, 03 Feb 2009 14:08:57 EST news152892495 University of Michigan Health System researchers have published new data to help answer two dreaded questions: "Is it cancer?" and "What type of treatment should I have?" http://www.physorg.com/news152802970.html Medicine & Health Mon, 02 Feb 2009 13:16:41 EST news152802970 While chronic inflammation is widely believed to be a predisposing factor for colon cancer, the exact mechanisms linking these conditions have remained elusive. Scientists at the Melbourne Branch of the international Ludwig Institute for Cancer Research (LICR) and the Technical University Munich have jointly discovered a new piece of this puzzle by demonstrating how the Stat3 protein links inflammation to tumor development, a discovery that may well lead to the identification of new therapeutic targets for colon cancer. http://www.physorg.com/news152801922.html Medicine & Health Mon, 02 Feb 2009 13:00:32 EST news152801922 Bladder cancer is much more likely to be deadly for women and African-Americans, but the reasons long believed to explain the phenomenon account for only part of the differences for such patients compared to their white and male counterparts, according to results published in the Jan. 1 issue of the journal Cancer. http://www.physorg.com/news150646734.html Medicine & Health Thu, 08 Jan 2009 14:18:54 EST news150646734 Researchers from the University of Granada and the University of Barcelona have shown that treatment with maslinic acid, a triterpenoid compound isolated from olive-skin pomace, results in a significant inhibition of cell proliferation and causes apoptotic death in colon-cancer cells. Maslinic acid is a novel natural compound and it is able to induce apoptosis or programmed death in human HT29 colon-cancer cells via the intrinsic mitochondrial pathway. Scientifics suggest this could be a useful new therapeutic strategy for the treatment of colon carcinoma. http://www.physorg.com/news150636441.html Medicine & Health Thu, 08 Jan 2009 11:27:21 EST news150636441
