In a radical new approach to attacking cancer, researchers will soon attempt to kill tumors by infecting them with viruses that cause ailments like the common cold.

This virus therapy treatment -- considered the third pillar alongside chemotherapy and radiation -- could one day become standard battle against cancer.

One Belfast doctor says anything that could improve the lives of cancer patients is worth a try. And try is exactly what Leonard Seymour, Professor of Gene Therapy at Oxford University, plans to do when he begins leading trials later this year.

Seymour, who has been working with viruses that kill cancer cells while sparing healthy tissue, will use a stealth virus masked from the body's immune system with a polymer coat that could travel through the bloodstream and reach tumors.

Two viruses are likely candidates for study in the first clinical trials -- adenovirus, cause of a cold-like virus, and vaccinia, cause of cowpox and a component in the smallpox vaccine.

Preliminary research on mice shows that virus therapy works well on tumors resistant to standard cancer drugs. But several years of trials will be necessary before the therapy can be considered for use on all cancers.

When World Tag Team Champion Rowdy Roddy Piper underwent back surgery for an injury he sustained during the World Wrestling Entertainment tour in Europe last month, the surgeons discovered two small marble-sized areas behind his stomach that gave cause for concern that he might have cancer. After biopsy, a diagnosis of non-Hodgkin's lymphoma was made. Because the cancer was found early, Piper is optimistic that he will be able to wrestle cancer to the mat to complete defeat.

"It seems like I have been fighting someone, something, someplace, in some manner, my whole life. But this fight, is one I am gonna win! Ever Forward." stated Piper on his blog.

Canadian-born Piper lives in the Portland, Oregon area. If you are a fan who would like to send Piper your support and best wishes, you can write to him at:

A variation of a virus that infects common household mice might be responsible for one-third of the breast cancer cases occurring in the US, according to research presented at the San Antonio Breast Cancer Symposium as reported by WedMD.

The mouse mammary tumor virus (MMTV), is spread like a cold virus from person to person, although the researchers are not certain if this virus is spread by sneezing or food contamination, or other means of transmission.

Mt. Sinai School of Medicine's Dr. James F. Holland is quoted as saying, "In Asia, the virus plays a very small role in causing the disease. The human breast cancer virus may explain why breast cancer rates differ throughout the world." The house mouse in question is not commonly found in Asia.

For so long, we have been told that the Asian diet pyramid, when compared to the Western diet pyramid, was one of the contributing factors in higher breast cancer cases for US women, and lower breast cancer cases for Asian women. It might well bea contributing factor still, as diet is firmly established as a cause for increasing the risks of all cancers. However, we cannot ignore that the researchers found the common house mouse virus present in the breast cancer tissue samples in 30-40 percent of the women from North America, Europe, and Australia.

That virus plays a role in the development of some cancers is a known, and it brings up interesting questions as to what leads to cancer, and potentially some explanations for the incidence of breast cancer for women who practice what is traditionally considered a healthy lifestyle and have none of the risk factors. Cancer is complex. As time goes on, I believe we are all going to sit back and be surprised at some of the causes for cancer as they are discovered.

Journalist, commentator, and cancer patient Leroy Sievers -- the guy we've written about before, the guy who has covered many wars and witnessed countless deaths, the guy who is now observing his own death as cancer in his lungs and spine chip away at his life -- has realized that getting good news takes some getting used to.

Sievers got some good news recently. He learned that the new combination of chemotherapy drugs he's been receiving has shrunk the tumors in his lungs. And scans show the tumor on his spine is healing. It's taken him days to truly understand this concept -- this concept of hope that has miraculously delivered him more time. He didn't expect it.

Sievers fully expected that he would soon be dead. That's why he's been savoring the cold, crisp fall days -- because he was not certain he would ever see such a season. He was sure he would never host another Halloween party either -- a party he canceled this year due to his health. But now, as he takes in this new sensation of hope, he considers the possibility he may be around for another party. And he thinks he'll dress up as a tumor. Halloween is one time when good taste is never important, he says.

Sievers, who offers a weekly personal health update for NPR, available in print or in podcast format on his blog, plans to keep living in the moment. He doesn't want to overdo this hope thing. So right now, he is simply enjoying the colorful leaves -- and the season he calls one of his favorites.

For women with estrogen-driven breast cancer suffering the symptoms of menopause, being prescribed traditional hormone replacement therapy (HRT) is out of the question. The risks are simply too great in introducing any estrogen into the body. There are few alternatives and many women decide to suffer with hot flashes, flushes, night sweats and cold flashes, a clammy feeling, sporadic rapid heart beat, irritability, mood swings, sudden tears, insomnia, fatigue, feelings of anxiety, dread, apprehension, difficulty concentrating, disorientation, depression and mental confusion -- without any significant relief. One of the alternatives is personalized natural hormone replacement therapy that is individually mixed specific to each woman's needs.

According to Sydney Menopause Centre at Randwick's Royal Hospital for Women director Dr John Eden, who has diagnosed two women patients with uterine cancer, believes the cancer is linked to natural hormone replacement therapy. Australian doctors are warning women to think twice before taking handmade hormone compounds prepared by chemists, due to the danger that these preparations can lead to elevated hormone levels that could lead to excessive bleeding, increased risk of breast and uterine cancer and blood clots.

"Many women think they are getting a herbal treatment and are shocked to learn they are getting a hormone treatment," stated Dr Eden. Dr Helena Teede, research director at the Jean Hailes Foundation, also added that many women were unaware these preparations were not approved by the Therapeutic Goods Administration.

Lance Armstrong sat down with ABC News This Week's George Stephanopoulos to talk about RAGBRAI -- the politics of cancer research funding -- and bringing the issues of cancer back as a national priority and into the hearts and minds of the American people. At this point in time, concerning cancer as an epidemic that strikes one in two men and one in three women, Armstrong said, "There are people who never needed to die -- never needed to go through the pain and suffering -- it's got to stop."

Of the RAGBRAI he participated in last week in Iowa, he joked that he enjoyed it much more than riding through the Alps during the Tour de France. In the RAGBRAI, a seven day bike tour, he was amazed at the sheer relaxed fun of it all. Armstrong spoke about drinking cold beer and eating coconut cream pie. He told Stephanopoulos that ladies were asking him what his favorite pie was, because in each town square there are home baked pies waiting for the cyclists.

Armstrong hopes that by talking to the voters of Iowa, a pivotal political state during presidential campaigns, he will spark interest in discussion and debate about cancer issues. Ultimately, during the presidential and vice-presidential debates, he would like to see one of the moderators ask the candidates directly, "What's your plan?" concerning cancer -- the number one killer of people in this country.

Armstrong said he was not looking to get elected to political office and wanted to stay neutral and apolitical. What he is looking to do, he said, is start a movement. Of a political future -- Armstrong said, "Never say never." You can watch ABC News This Week's George Stephanopoulos interview with Lance Armstrong video here.

I wish I could reverse the damage I've already done to my skin after too much time spent in the scorching sun, in search of a tan. It's seems unfair that a tan is so temporary -- yet its damage is everlasting. And it seems crazy that so many people are still searching for a tan -- when it has become so clear that is it so harmful.

As many as 60,000 people a year die from too much sun -- mostly from malignant skin cancer -- according to the World Health Organization (WHO). About 48,000 deaths are caused by malignant melanomas, and 12,000 deaths are caused by other kinds of skin cancer. And 90 percent of these cancers are caused by ultraviolet light from the sun. Cancer is not the only side effect of sun exposure, though -- serious sunburn, wrinkling, eye cataracts, growths on the flesh of the eye, cold sores, and other illness can result from the sun.

We all need some sun -- the vitamin D that is produced in the body by the sun helps to prevent disease and immune disorders. But too much is dangerous and sometimes deadly. Yet almost all ill effects from the sun can be prevented. And the WHO has released a report that advises people to seek shade, to use sunscreen with an SPF of at least 15, and to stay out of tanning salons. The report operates under the premise that sunscreens be used not to prolong sun exposure but to protect the skin when exposure is unavoidable.

Before my radiation for breast cancer, I heard horror stories about the treatment. I heard that I might be extremely tired and severely burned and that I might feel generally unwell for the time it would take to completely zap any and all traces of cancer surrounding my breast. But my own radiation wasn't all that bad -- and really, the worst part of the whole therapy for me was the drive to and from the cancer center every day for seven weeks. It was a hassle, a nuisance, a bother. There were other small annoyances throughout the course of my radiation, but they were minimal -- thanks to some secrets that were shared with me along the scorching path of radiation and beyond. And here are seven of them.

Texas cancer researchers are reporting significant success in survival rates of men with recurrent prostate cancer when treated with a one-two combination of radiation and suicide gene therapy -- all of which might one day lead to an effective long term prostate cancer vaccine. The Methodist Hospital in Houston researchers, who conducted the five-year study, reported improvement in patients with all stages of prostate cancer undergoing the combination treatment when compared to the results of patients receiving standard radiation at other institutions.

According to researchers, low-risk patients had 100 percent survival rate at five years, and the intermediate and high risk group had 90 percent survival rate at five years. “This method not only treats the tumor area with radiation,” said Dr. Brian Butler, chief of radiation oncology at The Methodist Hospital in Houston. “But it also creates a system of assassins to go out and look for these cancer cells throughout the body. We are using the body’s own immunological system to help identify the cancer and kill it.” Amazing.
