World cancer experts have finally declared what NewsTarget readers learned nearly four years ago: That processed meats cause cancer, and anyone seeking to avoid cancer should avoid eating all processed meats for life.

Hundreds of cancer researchers took part in a five-year project spanning more than 7,000 clinical studies and designed to document the links between diet and cancer. Their conclusion, published in the World Cancer Research Fund's report, Food, Nutrition, Physical Activity and the Prevention of Cancer: a Global Perspective (2007), has rocked the health world with a declaration that all people should immediately stop buying and eating processed meat products and that all processed meat should be avoided for life!

NewsTarget published a very interesting article regarding different factors that are damaging our health. 

Parents directly poison their children every day with products far more dangerous than Mattel toys.

Scientists have pinpointed a set of common variations in human DNA that signal a higher risk for prostate cancer in men who carry them. Some of these variations are more common in African-American men, which may help explain why prostate cancer rates are higher in African Americans than in men of other races.

The findings, published in 3 separate studies, may lead to genetic tests that will help identify those most at risk for the disease. The findings may also help unlock the biological mysteries behind prostate cancer, which could speed up the discovery of new treatments.

The 3 studies focus on DNA variations located on chromosome 8 in some men. The variations may be linked to as many as 68% of prostate cancer cases in African Americans, 60% in Japanese Americans, 46% in Latinos, 45% in native Hawaiians and 32% in whites, the authors of 1 of the studies calculate.

(CBS) CHICAGO Drugs used to treat skin conditions were prescribed to millions of users for years before federal authorities warned that the medicines might cause cancer. CBS station WBBM-TV In Chicago's Dave Savini reports on the risks that some say should have been made known from the start.

“I would never have put this in my body had I known how toxic and potent this drug was,” says Traci Reilly of Naperville, who believes two widely prescribed medications may be responsible for her breast cancer. “I noticed a lump in my right breast which is the exact area where I was using the drug.”

AUSTRALIAN researchers have discovered a new way that cancer can be passed down from parents to children that will allow them to diagnose the disease earlier.

Previously researchers believed young cancer sufferers inherited a parent's gene mutation.
However doctors were at a loss to explain why tests showed no sign of genetic mutation in some people with cancer.

Now researchers from St Vincent's Hospital in Sydney and the University of New South Wales have discovered that a chemical which paralyses part of the body's DNA can also be passed down from parents to children and cause cancer.

Gonorrhea, a common sexually transmitted infection, can double the risk of bladder cancer in men, researchers said on Tuesday.

Earlier studies had already suggested a link and scientists from the Harvard School of Public Health in Massachusetts who monitored the health of 51,529 American men found 286 cases of bladder cancer in men who had had the infection.

"We observed a two-fold increase in bladder cancer risk among men with a history of Gonorrhea," said Dr Dominique Michaud, the lead author of the research reported in the British Journal of Cancer.

The link was stronger for invasive and advanced bladder cancer, which is more serious and difficult to treat, and among smokers.

Researchers at the University of Southern California (USC) recently made significant strides toward settling a decades-old debate centering on the role played by stem cells in cancer development.

According to the study's findings, which appear in an upcoming issue of Nature Genetics and now available online, genes that are reversibly repressed in embryonic stem cells are over-represented among genes that are permanently silenced in cancers; this link lends support to the increasingly discussed theory that cancer is rooted in small populations of stem cells.

USC researchers uncovered this link after observing that of 177 genes repressed by Polycomb group (PcG) proteins, fully 77 showed evidence of cancer-associated enzymatic modification of DNA (known as methylation). "Finding that a Polycomb target in an embryonic stem cell is 12 times more likely to become abnormally methylated in cancer is highly significant," says Peter Laird, Ph.D., one of the lead researchers and associate professor of surgery, biochemistry and molecular biology, and director of basic research for surgery at the Keck School of Medicine of USC.

Scientists have identified a gene linked to the most common type of kidney cancer in children, and expressed hope this might help doctors determine which young patients are most at risk of dying.

Writing on Thursday in the journal Science, Massachusetts General Hospital researchers said about 30 percent of cases of the cancer called Wilms tumor involve mutations in a gene called WTX located on the sex-determining X chromosome.

About 90 percent of childhood kidney cancer cases are Wilms tumor. It occurs in roughly one in 10,000 children worldwide. It is treated with surgery and chemotherapy, with about 80 percent of patients surviving. It usually appears by age 5.

The disease also is called nephroblastoma.

Drinking an excess of cow's milk can promote cancer growth, according to Dr. T. Collin Campbell, Emeritus professor from Cornell University. After 27 years of animal research, Dr. Campbell came to that rather surprising conclusion which he revealed in his book, "China Study."

Dr. Campbell wrote a book on diet and cancer in 1982 that shocked U.S. medical authorities, as he organized an epidemiological study in China seeking associations between diets and diseases. The New York Times called the study the "greatest in the world" of epidemiological studies.

In Dr. Campbell's experiments, two groups of rats were exposed to equally high doses of highly carcinogenic aflatoxin to induce cancer. The rats were then fed a diet either with 20 percent glutencasein from animals. After a certain period, cancer cells did not increase in rats on the gluten diet, while the number of cancer cells in the rats on the casein diet drastically increased. from plants, or 20 percent.

A third of adults in Wales believe getting cancer is down to fate and are unaware many cases could be prevented, researchers have found.

Cancer Research UK, which surveyed 4,000 people, said more than half of all cases of cancer could be prevented.

But researchers found 33% of Welsh adults thought it was down to destiny, compared with the UK average of 27%.

The charity said it was alarming many people were not aware making lifestyle changes could help reduce their risk.

BETHESDA, Md. An environmental group says Maryland's air has cancer-causing toxins at levels far above what the federal government deems safe.

The report was released by Environment Maryland as part of a push to make Maryland the eleventh state to follow California's stricter auto emissions standards.The group's report is based on an analysis of federal data released earlier this year.

It found that the risk of cancer from all air toxins was at least ten times higher than the federal standard in each of the state's 23 counties and Baltimore City. The report didn't include data on how Maryland's levels compare with the rest of the country.

BALTIMORE, Dec. 26 (UPI) -- Men with early prostate cancer who eat a vegetarian diet, exercise and reduce stress may lower their risk of cancer progression, says a U.S. study.

The 93 study participants were men with early-stage prostate cancer who had chosen "watchful waiting" instead of active treatment for their prostate cancer.

During the one-year study, six men in the usual care group underwent conventional treatment because of rising prostate specific antigen, known as PSA, or evidence of progression from magnetic resonance imaging. In contrast, none of the men in the comprehensive lifestyle group, who followed a very-low-fat diet of 10 percent or less of daily calories, needed treatment. PSA levels decreased 4 percent in the lifestyle group, whereas PSA levels increased 6 percent in the usual-care group.

A key enzyme that cuts short our cellular lifespan in an effort to thwart cancer has now been linked to body mass.

Until now, scientists believed that our relatively long lifespans controlled the expression of telomerase—an enzyme that can lengthen the lives of cells, but can also increase the rate of cancer.

Vera Gorbunova, assistant professor of biology at the University of Rochester, conducted a first-of-its-kind study to discover why some animals express telomerase while others, like humans, don't. The findings are reported in today's issue of Aging Cell.

Naisan Naingisan, 25, from Korr village in Marsabit District has a large wound that started as a growth on her left leg. She cannot afford to go to hospital.

Could death caused by cancer be looming behind the expensive prospecting for oil going on in Kenya?

A survey in some remote villages where foreign companies sunk oil wells in Marsabit District almost two decades ago reveals shocking statistics of villagers who have contracted throat cancer and others who have died of it.

The new claims are likely to turn the spotlight on international oil firms, which are currently engaged in the search for oil at the Kenyan Coast and elsewhere.

BEIJING (Reuters) - China accounts for about half of the global annual death toll from stomach cancer due to the Chinese taste for pickled and smoked food and unabashed enthusiasm for smoking, the official Xinhua news agency said.

The disease kills about 300,000 people in China a year and there are 400,000 new cases reported annually, Xinhua said in a report seen on Wednesday.

Only lung and liver cancer kill more people in China, it quoted Jin Maolin, a doctor at Peking University, as saying.

A Danish study shows no rise in cancer among people who've used cell phones as long as 21 years.

The study included more than 420,000 Danes who got their first cell phone between 1982 and 1995.

Some of those people kept their phones as long as 21 years. But, on average, they had cell phone service for 8.5 years.

The study's researchers included Joachim Schuz, PhD, of the Danish Cancer Society. It tracked cancers among the cell phone users from the start in 1982-1995 through 2002.

NEW YORK (Reuters Health) - Eating lots of sugar and sugar-sweetened foods could increase a person's likelihood of developing cancer of the pancreas, by far one of the deadliest types of cancer, Swedish researchers report.

Dr. Susanna C. Larsson of the Karolinska Institute in Stockholm and her colleagues found that pancreatic cancer was significantly more likely to strike men and women who added the most sugar to their food and consumed the greatest quantities of soft drinks.

The researchers followed 77,797 men and women aged 45 to 83 for an average of about seven years. Those who reported eating five or more servings of added sugar daily, for example sugar added to tea, coffee or cereal, were 69 percent more likely to develop pancreatic cancer than those who never added sugar to their food or drink.

New clues about how tumors prepare for cancer's deadly spread may open up new avenues for cancer prevention and treatment.

A Japanese study suggests that early in lung cancer's progression, cells within a tumor may pave the way for cancer's invasion by triggering processes that allow for the spread of disease. By interrupting these signals, researchers were able to block the development of cancer's spread to lungs in mice.

Cancer advances through a process of metastasis in which the cancer spreads from the initial site to other areas of the body, making it more deadly and difficult to treat. By learning more about the processes that trigger this spread, researchers say they may be able to develop new cancer treatment strategies.

WASHINGTON (Reuters) - Stem cells -- the master cells that give rise to all the blood and tissue in the body -- may also be responsible for tumors, according to two separate studies published on Sunday.

Canadian and Italian researchers both found that specialized colon cancer stem cells appeared to be the sources of colon cancer tumors in mice.

Their findings, published in the journal Nature, support the idea that future cancer treatments will have to home in on cancer stem cells.

Similar findings have been seen for leukemia, breast and brain cancers, but the two studies are the first to show cancer stem cells are also responsible for colon tumors.

AN unknown genetic and environmental cocktail has sparked a mysterious rise in blood cancers in Australia with rates almost doubling over the past two decades.

While most cancers have declined or stabilised, the incidence of blood cancers such as lymphoma is on the rise.

New cases of blood cancers have spiked from nearly 4000 cases in 1983 to more than 7500 diagnosed in 2001.

Blood cancers include leukemia and Hodgkin's lymphoma, the condition from which singer Delta Goodrem suffered.
