Weather Conditions May Affect Prostate Cancer Patients.
A unique swotting links dry, cold weather to higher rates of prostate cancer. While the findings don't corroborate a direct link, researchers suspect that weather may affect adulteration and, in turn, boost prostate cancer rates. "We found that colder weather, and downcast rainfall, were strongly correlated with prostate cancer," researcher Sophie St-Hilaire, of Idaho State University, said in a scuttlebutt release.
So "Although we can't say exactly why this correlation exists, the trends are constant with what we would expect given the effects of climate on the deposition, absorption, and degradation of persistent systematic pollutants including pesticides". St-Hilaire and colleagues studied prostate cancer rates in counties in the United States and looked for links to state weather patterns.
They found a link, and suggest it may exist because polar weather slows the degradation of pollutants. Prostate cancer will strike about one in six men, according to CV information in the study. Reports suggest it's more common in the northern hemisphere.

Patients With Cancer Choose Surgery
Patients With Cancer Choose Surgery.
People with talk cancer who endure surgery before receiving radiation treatment fare better than those who start treatment with chemotherapy, according to a small reborn study. Many patients may be hesitant to begin their treatment with an invasive procedure, University of Michigan researchers noted. But advanced surgical techniques can pick up patients' chances for survival, the authors illustrious in a university news release. The study was published online Dec 26, 2013 in JAMA Otolaryngology Head and Neck Surgery.
Nearly 14000 Americans will be diagnosed with voice cancer this year and 2,070 will Euphemistic depart from the disease, according to the American Cancer Society. "To a minor person with tongue cancer, chemotherapy may sound like a better option than surgery with extensive reconstruction," inquiry author Dr Douglas Chepeha, a professor of otolaryngology-head and neck surgery at the University of Michigan Medical School, said in the despatch release. "But patients with oral pit cancer can't tolerate induction chemotherapy as well as they can handle surgery with follow-up radiation".
And "Our techniques of reconstruction are advanced and propose patients better survival and functional outcomes". The retreat involved 19 people with advanced oral cavity mouth cancer. All of the participants were given an first dose of chemotherapy (called "induction" chemotherapy). Patients whose cancer was reduced in square footage by 50 percent received more chemotherapy as well as radiation therapy.

Experts Urge Parents To Buy Kids Sunglasses Against Ultraviolet Radiation
Experts Urge Parents To Buy Kids Sunglasses Against Ultraviolet Radiation.
With May designated as UV awareness month, experts are occupation on parents to give particular heed to the safety of their children's eyes this summer. Although eye keeping is a concern for people of all ages, Prevent Blindness America, the nation's oldest eye healthiness and safety organization, warns that children are particularly vulnerable to the harmful ultraviolet A and B (UVA and UVB) price that can accompany sun exposure. For one, children in the main spend more time in the sun, the group noted.
In addition, the organization highlights the American Optometric Association's cautionary judgement that the lenses of young eyes are more transparent than that of adults, risking retinal location to a greater degree of short wavelength light. "We need to remember to take care of our eyes from UV every day of the year," Hugh R Parry, president and CEO of Prevent Blindness America, said in a communication release. "UV rays reflecting off the water, sand, pavement and even snow are uncommonly dangerous. We can encourage our children to wear the proper ogle protection by leading by example".
UV exposure has been linked to the onset of cataracts, macular degeneration and a major array of eye health issues, the experts noted. Prevent Blindness America advises that each and every one who goes out in the sun should wear sunglasses that block out 99 percent to 100 percent of both UVA and UVB dispersal - noting that sunglasses without such protection can actually cause the pupils to dilate, thereby doing more hurt than good. A wide-brimmed hat or cap also offers some measure of eye protection, the batch suggested.
With specific respect to children, Prevent Blindness America further encourages parents to make safe that sunglasses fit their child's face properly and shields the sun's rays from all directions. The league points out that wrap-around sunglasses might be optimal in the later regard, because they additionally defend the skin immediately surrounding a child's eyes. Sunglasses, they note, should always be composed of impact-resistant polycarbonates, rather than glass, and should be scratch-free.

Cancer Risk From CT Scans Lower Than Previously Thought
Cancer Risk From CT Scans Lower Than Previously Thought.
The hazard of developing cancer as a sequel of radiation exposure from CT scans may be move than previously thought, new research suggests. That finding, scheduled to be presented Wednesday at the annual tryst of the Radiological Society of North America in Chicago, is based on an eight-year study of Medicare records covering nearly 11 million patients. "What we found is that overall between two and four out of every 10000 patients who be subjected to a CT scan are at risk for developing secondary cancers as a result of that emission exposure," said Aabed Meer, an MD candidate in the department of radiology at Stanford University in Palo Alto, Calif. "And that risk, I would say, is decrease than we expected it to be".
As a result, patients who paucity a CT scan should not be fearful of the consequences, Meer stated. "If you have a caress and need a CT scan of the head, the benefits of that scan at that moment outweigh the very stripling possibility of developing a cancer as a result of the scan itself. CT scans do amazing things in terms of diagnosis. Yes, there is some dispersal risk. But that small risk should always be put in context".
The authors set out to quantify that jeopardize by sifting through the medical records of elderly patients covered by Medicare between 1998 and 2005. The researchers separated the matter into two periods: 1998 to 2001 and 2002 to 2005. In the earlier period, 42 percent of the patients had undergone CT scans. For the epoch 2002 to 2005, that force rose to 49 percent, which was not surprising given the increasing use of scans in US medical care.
Within each group, the explore team reviewed the number and sort of CT scans administered to see how many patients received low-dose radiation (50 to 100 millisieverts) and how many got high-dose diffusion (more than 100 millisieverts). They then estimated how many cancers were induced using example cancer risk models.

Mammography Is Against The Lifetime Risk Of Breast Cancer
Mammography Is Against The Lifetime Risk Of Breast Cancer.
The embryonic cancer endanger that radiation from mammograms might cause is slight compared to the benefits of lives saved from primordial detection, new Canadian research says. The study is published online and will appear in the January 2011 linocut issue of Radiology. This risk of radiation-induced titty cancers "is mentioned periodically by women and people who are critiquing screening and how often it should be done and in whom," said writing-room author Dr Martin J Yaffe, a senior scientist in imaging inquiry at Sunnybrook Health Sciences Centre and a professor in the departments of medical biophysics and medical imaging at the University of Toronto. "This muse about says that the good obtained from having a screening mammogram far exceeds the chance you might have from the radiation received from the low-dose mammogram," said Dr Arnold J Rotter, supervisor of the computed tomography section and a clinical professor of radiology at the City of Hope Comprehensive Cancer Center, in Duarte, Calif.
Yaffe and his colleague, Dr James G Mainprize, developed a rigorous facsimile to estimate the risk of radiation-induced breast cancer following exposure to dispersal from mammograms, and then estimated the number of breast cancers, fatal breast cancers and years of vitality lost attributable to the mammography's screening radiation. They plugged into the model a typical emanation dose for digital mammography, 3,7 milligrays (mGy), and applied it to 100000 hypothetical women, screened annually between the ages of 40 and 55 and then every other year between the ages of 56 and 74.
They purposeful what the hazard would be from the radiation over time and took into account other causes of death. "We used an unmixed risk model," Yaffe said. That is, it computes "if a certain tot of people get a certain amount of radiation, down the road a certain number of cancers will be caused".

Solar Ultraviolet Radiation Danger At Ski Resorts
Solar Ultraviolet Radiation Danger At Ski Resorts.
Skiers and other out of doors enthusiasts beggary to be aware that factors such as weather conditions and time of day can cause considerable modification in the levels of ultraviolet (UV) radiation during the winter, researchers say. They analyzed observations collected between 2001 and 2003 at 32 high-altitude ski resorts in western North America. They also interviewed of age guests at the resorts and looked at their clothing and equipment in order to assess their plain of sun protection.
Average UV levels at the ski resorts were moderately low but diverse substantially, the researchers found. Clear skies, time close to noon, and more hours of full knowledge as the ski season progressed were the strongest predictors of increased UV radiation. The researchers also found child associations between higher UV radiation and altitude, longitude and temperature.
However, elevated UV levels were not associated with increased use of sun-protection measures, such as sunscreen lip balm, germaneness of sunscreen 30 minutes before skiing, wearing a precede cover with a brim, or wearing gloves. The deliberate over did find that as UV levels increased, adults were more likely to wear sunscreen with a lowest 15 SPF and to reapply it after two hours, and more likely to wear sunglasses or goggles. Men were more in all probability than women to use sunscreen.
