High Levels of Cancer-Linked Chemical in E-Cigarette Vapor, Study Finds

Posted 4 days ago by Drugs.com

WEDNESDAY, Jan. 21, 2015 – E-cigarette vapor can contain cancer-causing formaldehyde at levels up to 15 times higher than regular cigarettes, a new study finds. Researchers found that e-cigarettes operated at high voltages produce vapor with large amounts of formaldehyde-containing chemical compounds. This could pose a risk to users who increase the voltage on their e-cigarette to increase the delivery of vaporized nicotine, said study co-author James Pankow, a professor of chemistry and civil and environmental engineering at Portland State University in Oregon. "We've found there is a hidden form of formaldehyde in e-cigarette vapor that has not typically been measured. It's a chemical that contains formaldehyde in it, and that formaldehyde can be released after inhalation," Pankow said. "People shouldn't assume these e-cigarettes are completely safe." The findings appear in a letter ... Read more

Therapy Dogs Help Cancer Patients Cope With Tough Treatments

Posted 6 days ago by Drugs.com

TUESDAY, Jan. 20, 2015 – People undergoing chemotherapy and radiation for cancer may get an emotional lift from man's best friend, a new study suggests. The study, of patients with head and neck cancers, is among the first to scientifically test the effects of therapy dogs – trained and certified pooches brought in to ease human anxiety, whether it's from trauma, injury or illness. To dog lovers, it may be a no-brainer that canine companions bring comfort. And therapy dogs are already a fixture in some U.S. hospitals, as well as nursing homes, social service agencies, and other settings where people are in need. Dogs offer something that even the best-intentioned human caregiver can't quite match, said Rachel McPherson, executive director of the New York City-based Good Dog Foundation. "They give unconditional love," said McPherson, whose organization trains and certifies therapy dogs ... Read more

Cancer Survivors May Struggle for Years With Mental, Physical Problems

Posted 14 days ago by Drugs.com

MONDAY, Jan. 12, 2015 – Many U.S. cancer survivors have unresolved physical and mental health issues long after being cured, a new study finds. One expert wasn't surprised. "Many oncologists intuit that their patients may have unmet needs, but believe that these will diminish with time – the current study challenges that notion," said Dr. James Ferrara, chair of cancer medicine at Tisch Cancer Institute at Mount Sinai in New York City. The new study involved more than 1,500 cancer survivors who completed an American Cancer Society survey asking about unmet needs. More than one-third pointed to physical problems related to their cancer or its treatment. For example, incontinence and sexual problems were especially common among prostate cancer survivors, the report found. Cancer care often took a toll on financial health, too. About 20 percent of the survey respondents said they ... Read more

Study Says Biopsies Are Safe

Posted 15 days ago by Drugs.com

FRIDAY, Jan. 9, 2015 – Cancer biopsies do not cause the disease to spread, says a new study that dispels a common myth. "This study shows that physicians and patients should feel reassured that a biopsy is very safe," said study senior investigator Dr. Michael Wallace, a gastroenterologist and professor of medicine at the Mayo Clinic in Jacksonville, Fla. The study included more than 2,000 people with pancreatic cancer. Those who received a biopsy using a technique called fine needle aspiration lived longer and had better outcomes than those who did not have a biopsy. "We do millions of biopsies of cancer a year in the U.S., but one or two case studies have led to this common myth that biopsies spread cancer," Wallace said in a clinic news release. The findings in the Jan. 9 online issue of the journal Gut are likely to apply to other cancers because fine needle aspiration is used to ... Read more

Cancer Groups Urge More Regulation of E-Cigarettes

Posted 17 days ago by Drugs.com

THURSDAY, Jan. 8, 2015 – The potential health hazards of e-cigarettes remain unclear, and more regulation on their use is needed, say two groups representing cancer researchers and specialists. The American Association for Cancer Research (AACR) and the American Society of Clinical Oncology (ASCO) together issued a list of recommendations on Thursday aimed at bringing e-cigarette regulations more in line with those of traditional cigarettes. In a news release, the two groups pointed out that e-cigarettes, which are not smoked but deliver nicotine in a aerosolized form, are not yet regulated by the U.S. Food and Drug Administration. They called on the FDA to regulate all types of e-cigarette products that also meet the standard definition of tobacco products. Those that do not meet that standard should be regulated by whichever means the FDA feels appropriate, the cancer groups added. ... Read more

Study Finds Link Between Cancer Diagnosis, Stroke Risk

Posted 17 days ago by Drugs.com

WEDNESDAY, Jan. 7, 2015 – Newly diagnosed cancer patients are at increased risk for stroke in the months after they find out they have the disease. And the risk of stroke is higher among those with more aggressive cancer, a new study says. The findings come from an analysis of Medicare claims submitted between 2001 and 2009 by patients aged 66 and older who had been diagnosed with breast, colorectal, lung, prostate and pancreatic cancer. Compared to cancer-free seniors, those with cancer had a much higher risk of stroke. And the risk was highest in the first three months after cancer diagnosis, when the intensity of chemotherapy, radiation and other treatments is typically highest, the researchers at Weill Cornell Medical College in New York City said in a college news release. The risk of stroke was highest among patients with lung, pancreatic and colorectal cancers, which are often ... Read more

Random Mutations Responsible for About Two-Thirds of Cancer Risk: Study

Posted 5 Jan 2015 by Drugs.com

THURSDAY, Jan. 1, 2015 – Although about one-third of cancers can be linked to environmental factors or inherited genes, new research suggests the remaining two-thirds may be caused by random mutations. These mutations take place when stem cells divide, according to the study by researchers at Johns Hopkins Kimmel Cancer Center. Stem cells regenerate and replace cells that die off. If stem cells make random mistakes and mutate during this cell division, cancer can develop. The more of these mistakes that happen, the greater a person's risk that cells will grow out of control and develop into cancer, the study authors explained in a Hopkins news release. Although unhealthy lifestyle choices, such as smoking, are a contributing factor, the researchers concluded that the "bad luck" of random mutations plays a key role in the development of many forms of cancer. "All cancers are caused by a ... Read more

Falling Cancer Death Rate Means 1.5 Million Lives Saved Over 20 Years

Posted 5 Jan 2015 by Drugs.com

WEDNESDAY, Dec. 31, 2014 – Progress in the war against cancer has triggered a 22 percent drop in U.S. deaths over the past two decades, translating to about 1.5 million lives saved, a new American Cancer Society report finds. Even so, the annual report also predict that within a few years, cancer will overtake heart disease as the leading killer of Americans. That's because "the decrease in mortality rates from heart disease has been much larger than the decrease in mortality from cancer," said Dr. Ahmedin Jemal, the cancer society's vice president of surveillance and health services research. "Cancer is a collection of maybe 200 diseases," he explained. "It's not like heart disease, where you have maybe some variation but it is a single entity compared to cancer." In 2011, the most recent year for which statistics are available, heart disease claimed the lives of more than 308,000 men ... Read more

Cancer Doctors Don't Discuss Herbs, Supplements With Patients

Posted 5 Jan 2015 by Drugs.com

MONDAY, Jan. 5, 2015 – Despite concerns about potentially dangerous interactions between cancer treatments and herbs and other supplements, most cancer doctors don't talk to their patients about these products, new research found. Fewer than half of cancer doctors – oncologists – bring up the subject of herbs or supplements with their patients, the researchers found. Many doctors cited their own lack of information as a major reason why they skip that conversation. "Lack of knowledge about herbs and supplements, and awareness of that lack of knowledge is probably one of the reasons why oncologists don't initiate the discussion," said the study's author, Dr. Richard Lee, medical director of the Integrative Medicine Program at the University of Texas MD Anderson Cancer Center in Houston. "It's really about getting more research out there and more education so oncologists can feel ... Read more

Cancer Treatment Costs Weigh Heavily on Patients, Study Finds

Posted 19 Dec 2014 by Drugs.com

FRIDAY, Dec. 19, 2014 – The cost of cancer treatment can cause financial stress that threatens patients' well-being, a new study finds. Researchers examined data from 1,000 people in the United States who had been diagnosed with colorectal or lung cancer. Of those patients, almost 900 had finished their treatments and were cancer-free, and more than 100 had advanced cancer. Nearly half of the patients said they were struggling to pay their medical bills, which was linked with a poorer health-related quality of life. This "financial toxicity" can impact cancer patients regardless of income, employment, or status of their cancer and other health problems, according to the study. "Our focus has been on how the cost of cancer care impacts a patient's well-being, and we found that patients are at risk of experiencing financial harm as a result of the treatments we prescribe," lead author ...

Cigarettes Cause One-Third of U.S. Cancer Deaths: Report

Posted 9 Dec 2014 by Drugs.com

TUESDAY, Dec. 9, 2014 – Despite large declines in smoking rates, cigarettes still cause about one-third of cancer deaths in the United States, according to a new study. "Our results indicate that cigarette smoking causes about three in 10 cancer deaths in the contemporary United States. Reducing smoking prevalence as rapidly as possible should be a top priority for U.S. public health efforts to prevent future cancer deaths," researchers from the American Cancer Society wrote. The researchers analyzed 2010 national data to get the latest numbers. The new cancer death estimate doesn't include deaths from secondhand smoke. It also doesn't include deaths from other types of tobacco use such as cigars, pipes, or smokeless tobacco. The study appears in the journal Annals of Epidemiology. More than 30 years ago, a groundbreaking study concluded that 30 percent of all cancer deaths in the ... Read more

Home Treatment for Cancer-Related Swelling May Slash Costs

Posted 8 Dec 2014 by Drugs.com

FRIDAY, Dec. 5, 2014 – Home treatment for cancer-related lymphedema – swelling due to fluid buildup – reduces the cost of treating the condition, a new study says. This swelling, which is caused by the removal of or damage to lymph nodes during cancer treatment, can be painful and debilitating. It's also incurable. Researchers examined the home use of pneumatic compression garments to treat lymphedema. The garments inflate and deflate in cycles to help drain buildup of lymph fluid that causes the swelling. The average annual cost of care for a patient with lymphedema fell from slightly more than $62,000 to $50,000 when the pneumatic compression devices were used at home, according to the study published online Dec. 3 in the journal PLoS One. "Total health-care costs for these patients are very high, but can be profoundly reduced with treatment intervention, in this case a compression ... Read more

Most Americans Agree With Right-to-Die Movement

Posted 8 Dec 2014 by Drugs.com

FRIDAY, Dec. 5, 2014 – Already-strong public support for right-to-die legislation has grown even stronger in the days since the planned death of 29-year-old brain cancer patient Brittany Maynard, a new HealthDay/Harris Poll has found. An overwhelming 74 percent of American adults now believe that terminally ill patients who are in great pain should have the right to end their lives, the poll found. Only 14 percent were opposed. Broad majorities also favor physician-assisted suicide and physician-administered euthanasia. Only three states – Oregon, Washington and Vermont – currently have right-to-die laws that allow physician-assisted suicide. "Public opinion on these issues seems to be far ahead of political leadership and legislative actions," said Humphrey Taylor, chairman of The Harris Poll. "Only a few states have legalized physician-assisted suicide and none have legalized ... Read more

Many Ignore Cancer's Warning Signs, Survey Finds

Posted 3 Dec 2014 by Drugs.com

TUESDAY, Dec. 2, 2014 – Many people ignore potential warning signs of cancer, a new British survey found. The study involved 1,700 people aged 50 and older in the United Kingdom who completed a health questionnaire listing 17 symptoms, including 10 widely publicized possible cancer symptoms. The symptoms included unexplained cough, bleeding, or significant changes in bowel or bladder activity. While 53 percent of the participants said they had experienced at least one of the potential cancer symptoms in the previous three months, only 2 percent thought cancer was a possible cause of those symptoms. In many cases, people attributed potential signs of cancer to reasons such as age, infection, arthritis, cysts and hemorrhoids, according to the Cancer Research U.K.-funded survey. It was published Dec. 2 in the journal PLOS One. "Most people with potential warning symptoms don't have ... Read more

Obesity Tied to Half a Million Cancers Worldwide, Report Shows

Posted 26 Nov 2014 by Drugs.com

WEDNESDAY, Nov. 26, 2014 – Obesity is associated with close to 500,000 new cancer cases worldwide each year, and nearly two-thirds of obesity-related cancers occur in North America and Europe, a new report shows. The analysis of data from 184 countries showed that excess weight was associated with 345,000 (5.4 percent) of new cancers in women in 2012, and 136,000 (1.9 percent) of new cancers in men in 2012. Among women, postmenopausal breast, endometrial and colon cancers accounted for nearly three-quarters (250,000 cases) of obesity-related cancers, while colon and kidney cancers accounted for more than two-thirds (nearly 90,000 cases) of obesity-related cancers in men. Excess weight was associated with about 8 percent of cancers in women and 3 percent of cancers in men in developed nations, compared with 1.5 percent of cancers in women and 0.3 percent of cancers in men in developing ...
