Lung Cancer Is More Funding
A recent study done by the Roy Castle Lung Cancer Foundation and Macmillan Cancer Relief showed that more than 38,000 people die from lung cancer each year in the UK. This makes lung cancer the biggest cancer killer. Despite these facts lung cancer receives just 4% of the national cancer research budget.
Lung cancer activists say the stigma linked to lung cancer, "smokers' caused this disease to themselves" means patients do not get the best support and information they need.
Everyone should remember that according to figures, one in 10 lung cancer cases are diagnosed in people who have never smoked.
Peter Cardy, chief executive of Macmillan Cancer Relief, added: "Lung cancer has been the poor relation for far too long and it's time to ensure patients get the care that they deserve.

The latest post from this diabetes watch blog reads as follows: Imaging For Brain Changes In Patients With Diabetes - Although people with diabetes are twice as likely as the general population to develop depression, the cause of this increased risk is not well understood. Now, a Joslin Diabetes Center-led collaboration has documented for the first time subtle changes in the gray matter of the brain of type 1 diabetes patients compared to control subjects who did not have diabetes. They made these observations using voxel-based morphometry (VBM), a relatively new magnetic resonance imaging (MRI) technology that allows researchers to take very sensitive measurements of small regions in the brain. For the first time, doctors have reason to ask if the increased risk of depression could in fact be due to changes in brain.......

Naturopath Stands Trial For Cancer Patient's Death
The parents have put their last hope in O'Connell, who has treated the boy with herbal medicine, nutrition and physiotherapy. He assured the parents that he would be able to save their son.
During the course of treatment O'Connell administered ultraviolet blood irradiation, in which he removed blood from Flanagan's system, passed it under ultraviolet light and injected it back into his body. O'Connell said that this would stimulate the immune system by increasing oxygen in the blood. However, Sean Flanagan was admitted to a hospital two days later with lung infection.
When he was discharged from the hospital, the UV light treatment was administered at home, which caused his oxygen saturation levels to drop. Subsequently O'Connell allegedly treated Sean Flanagan by injecting his blood with hydrogen peroxide. Flanagan's cause of death was listed as probable complications from the hydrogen peroxide treatment.
The case highlights the dangers of unproven alternative therapies, which many consider to be a safer alternative to scientifically proven modern medicine.

Why Blacks Are More Prone To Lung Cancer?
These results are from a study which is said to be the largest ever done on this subject. This study also found that Hispanic and Asian smokers were less likely than black smokers to develop lung cancer. This racial difference in risk of development of lung cancer was apparent only among light smokers. Once they smoke heavily the high risk caused by heavy smoking buffers the genetic difference between races. These racial differences disappear in those who smoke, more than a pack and a half per day.
Doctors have long known that blacks are substantially more likely than whites to develop lung cancer and more likely to die from it. But the reasons for the disparity are unclear.
Some say the difference is a matter of genetics, while others contend smoking habits may play a role. For example, researchers say blacks tend to puff more deeply than whites, which may expose them to more carcinogens. Smoking rates are also slightly higher among blacks, but whites tend to smoke more cigarettes a day.
In this study that was published in the latest issue of New England Journal of Medicine, researchers compared the lung cancer risk among ethnic groups who smoked the same amount. Researchers say that findings suggest genes may be one of the important factors that explain the racial difference in susceptibility to lung cancer.
This study involved more than 180,000 people, more than half of them belonged to minority ethnic groups.

Fish Oil Good For Heart, But No Help For Cancer
Researchers combed through the data from 38 different studies that tracked patients for up to 30 years, and came to the conclusion that omega-3 fatty acids that are present in the fish oil has no cancer protective effect. Dr. Catherine MacLean, the lead author and a researcher at the Rand Corp. and Greater Los Angeles Veterans Affairs Healthcare System say that although a few studies found some risk reduction for cancers of the breast, prostate and lung, those studies were relatively small and not definitive.
I Don't think this is going to be the last word on this issue. It has been shown over and over again that plays a key role in causation and prevention of cancer.
These researchers review includes studies that evaluated the effects of fish oil, in both pill form and as food on 11 kinds of cancer, mostly tumors of the breast, colon, lung or prostate. This new study appear in the latest issue of Journal of the American Medical Association
These 38 studies they have evaluated are very different among themselves involving different population groups and different levels of fish oil consumption. This limits the value of this analysis and precludes from making any definite conclusions.

Palliative Radiation Therapy Of Lung Cancer May Actually Save Lives
Now a group of Australian researchers have a surprising finding. They say that small doses of radiation that is used for palliation may actually save the lives of a few patients. They found that about one in a hundred patients with apparently terminal non-small cell lung cancer survived five or more years after the treatments, and 18 patients were apparently cured, these Australian researchers said.
Dr. Michael Mac Manus, who is a radiation oncologist at the Peter MacCallum Cancer Center in Melbourne, Australia, led this research. He and his colleagues followed 2,337 apparently incurable lung cancer patients who had received palliative doses of radiation.
Their findings appeared in the recent issue of journal Cancer. It says that about 1.1 percent of the 2,337 patients lived five or more years after treatment.

New Technology For Lung Cancer Detection
As I have previously written in this blog, spiral CT scan is a technique that is capable of detecting lung tumors early. In this type of CT scan, the physician obtains about 500 separate slice images of the chest with very high resolution. This would enable the physician to find small lung tumors, before it may have spread to other organs, much like a mammogram in breast cancer. The problem with spiral CT scan is that, it takes for ever to study the 500 or so slice that the machine produces for one person. Large-scale screening using this technique becomes practically impossible or at least very difficult because of the enormous amount of work involved.
Computer-aided detection (CAD), can theoretically replace much of manpower with the computer technology. The computer-aided system that is available so far has not been very sensitive to do the job without errors, so a large number of false positive results occur with CAD.
Now there is progress in this field. Researchers from University of Oxford Engineering Science department have developed a new technique incorporating a process called Visual Moving Features (VMF) for detecting pulmonary nodules. VMF detects a predefined structure in a subject by analyzing the image based on a representation of the structure constructed across a number of parallel image planes. The method has been tested on results from 12 clinical cases involving a total of 3875 sectional images and 106 lung nodules. The technology was so accurate that, every nodule recognized by a skilled radiologist was detected by the Oxford method.
May be this the technology of the future for early lung cancer detection.

Smokers Sue Philip Morris
Like other tobacco lawsuits, the complaint filed by four plaintiffs in federal court in Brooklyn alleges they were victims of deceptive marketing of a deadly product. It seeks class action status for anyone over the age of 50 who has smoked the equivalent of one pack a day for at least 20 years.
The plaintiffs have demanded yearly spiral Computerized axial tomography scans at the company's expense. The suit claims the procedure _ which can cost up to $500 and is not normally covered by health insurance could save thousands of lives by detecting lung cancer before it becomes deadly.
"Philip Morris is obligated morally, not just legally, to make a health investment to help prevent death and suffering caused by the Marlboro smoke," said the smokers' attorney Jerome H. Block.
Philip Morris USA Inc., the nation's largest cigarette company, had no immediate comment.
Tobacco companies have won two other so-called medical monitoring suits that went to trial. In a 2001 case brought against Philip Morris, a West Virginia jury found that the manufacturer had no obligation to provide cancer screening for the state's healthy and former smokers; a Louisiana jury made a similar finding in 2003.
The new suit describes a Computerized axial tomography scan as a simple procedure that can detect small tumors on the lungs far more effectively than conventional chest X-rays.

Compound Related To Vitamin A Fights Lung Cancer
This research was led by Dr. Ming You, director of the Chemoprevention Program at the Siteman Cancer Center at Washington University. Dr.You and his colleagues found that this compound, called bexarotene, is effective in prevention of lung cancer cells in mouse. They also found that this compound doesn't cause the severe skin irritations that have limited the use of other vitamin A derivatives in cancer therapies.
The ideal substance to prevent cancer would block tumor growth without causing unpleasant or dangerous side effects. In other studies, bexarotene showed some promise in cancer treatment. It extended survival in patients with non-small cell lung cancer, the most common type of lung cancer and one that has a five-year survival rate of less than 5 percent when diagnosed at the advanced stage.
In the current study, to be published in an upcoming issue of Oncogene, You, who is also professor of surgery, and Dr. Yian Wang, associate professor of surgery and their colleagues showed that lung-cancer-susceptible mice receiving non-toxic doses of bexarotene ended up with fewer and smaller benign and malignant tumors than mice that were not treated with bexarotene.
The researchers saw a reduction of almost 50 percent in terms of total amount of tumor in mice who were given bexarotene for 12 weeks after the animals had already developed benign tumors following injection of a lung carcinogen. Bexarotene also inhibited the progression of benign to malignant tumors by about 50 percent. The mice were engineered to have the genetic alterations seen in human lung cancers, so they readily develop lung cancer when given known lung carcinogens.

We engage a never-ending daily struggle to understand and defeat the hidden mysteries of cancer. This is a long and laborious fight, but some moments stand out as grim reminders of the severity of the problem and ruthlessness of the enemy. We recently heard about the sad demise of Peter Jennings, who was the news anchor of ABC News for a long time.
