Nasopharyngeal cancer is most prevalent in South China and kills one in every three victims. The disease is thought to be linked to diets rich in preserved foods, like salted fish.

Scientists will soon test an experimental treatment for nose and throat cancer that will train the patient's own white blood cells to fight the disease. Some classes of T-cells have memory. Once these cells are taken from the patient and are exposed to invaders that they successfully fought off, they should launch the same response when they are re-introduced back into the patients own body.

One of the researchers stated "We expect the T-cells to initiate a very aggressive inflammatory reaction and during the process, not only will the T-cells attack the cancer cells, but other immune cells in the body will be called in to eradicate the cancer cells".

On Tuesday, researchers announced that a three-drug cocktail may help women with HER2-positive breast cancer better than any other drug used on its own. About one quarter of women with breast cancer make up this HER2 category.

Tests on mice revealed using the three drugs along with breast cancer drug tamoxifen helped wipe out tumors altogether. And the tumors did not come back. This is the first time mice were cured of a very aggressive human breast tumor. Incidentally, when a single drug was used, tumors returned within several weeks.

The three wonder drugs used in this study -- all are monoclonal antibodies that precisely target certain aspects of tumors -- are the experimental drug pertuzumab; trastuzumab, also known as Herceptin; and gefitinib, or Iressa.

Published in the Journal of the National Cancer Institute, this study supports the notion that HER2-positive tumors eventually become resistant to one drug and attacking them on several fronts seems to work better.

Back in the news: the link between hormone replacement therapy (HRT) and breast cancer. This time, the connection is seemingly more conclusive than before, when some argued that many factors influence the risk of breast cancer, that HRT could not do the job all on its own.

Now, two separate studies offer up powerful evidence that HRT is linked to tumor growth. Case in point: when use of the therapy drops, so do incidences of breast cancer.

New figures in the New England Journal of Medicine suggest there have been 16,000 fewer cases of breast cancer nationwide since mid-2002, when women stopped taking their hormone pills following the federal Women's Health Initiative announcement connecting the therapy with increased risk of breast cancer, stroke, and heart attack.

Many did not want to believe HRT was to blame for so many breast cancer diagnoses. And maybe it's not the actual cause of the disease, but the fuel for tumors trying to grow.

These new findings do not appear to be a statistical fluke, says one doctor. Numbers have been computed and re-computed, and the message is clear: HRT is strongly implicated as the guilty party. There is just no other culprit, says a statistician at the National Cancer Institute.

Wyeth, maker of Premarin and Prempro -- two forms of hormone therapy -- continues to caution women against drawing any conclusions about HRT and breast cancer. There still may be broader explanation for the decline in cases, say their spokespeople.

This is a big question for those in the field of cancer immunotherapy, treatment based upon the concept of adjusting the immune system to reject and destroy tumors.

The National Cancer Institute along with a company called NewLink Genetics are looking to get FDA approval to start clinical trials of a drug that restricts a natural mechanism for immune suppression.

This enzyme named IDO, has been shown to help the fetus avoid rejection by the mother's immune system. This discovery led scientists to suspect and later prove that tumors express IDO.

Will suppressing IDO in humans help the immune system to seek out and kill cancer cells? This is what these scientists want to find out.

Doctor Mellor, a pediatric oncologist, says "What (cancers) do, we think, is make a protective cocoon so the immune system does not attack the tumor, so that gives you the therapeutic opportunity. If you stop IDO from blocking the response, you should allow the response, so now the specificity of the immune system is brought to bear directly on tumor cells"

Interesting stuff!

If the experimental breast cancer drug Tykerb continues to prove successful in study participants, it could be headed for FDA approval.

Tykerb, now in international study, showed in early studies to be even more effective and to have fewer side effects than similar breast cancer drug Herceptin. Both drugs are part of a cluster of targeted therapies that attack cancer cells while sparing healthy cells. Designed for use on women whose breast cancer is HER2 positive -- meaning it contains too much of an aggressive protein -- Tykerb may be a wonder drug, with the capability of effectively keeping breast cancer at bay.

Dr. Paul Goss of MA General Hospital says, "We're seeing Tykerb, which is a pill, which is easier to take, has a broader attack and gets inside cells. It's like an electrical circuit that's turned on, and Tykerb can pull the lever, the circuit breaker, and switch it off."

A U.K. researcher confirms what many dog lovers already know -- dogs are good for your health.

Apparently, dog owners are generally healthier than non-pet-owners. They have lower blood pressure and cholesterol, suffer fewer minor ailments, and stray from serious medical problems too. Dogs can prevent their owners from getting sick, help them recover more quickly when they do fall ill, and they can even warn of cancer, heart attack, epileptic seizures, and hypoglycemia, says Dr. Deborah Wells from the Canine Behaviour Centre of Queens University in Northern Ireland.

Wells, whose study is published in the British Journal of Health Psychology, says dogs buffer us from stress -- a well-known cause of illness -- and promote general well-being. Owning a dog leads to increased physical activity and increases development of social interactions -- both of which minimize stress and contribute to human health.

While Wells found those who own both dogs and cats benefit from their pets, dog owners enjoy improved health for much longer than cat owners.

There are sometimes silver linings to the darkest of cancer clouds. I know -- because I have the dark cloud of HER2 positive breast cancer hanging over my head. HER2 positive means the tumor removed from my breast was aggressive. It aggressively over-expressed a protein that accelerates tumor growth. And it led to a poor prognosis -- that might be considered a good one too.

You see, research on the whole HER2 issue is turning up some pretty powerful potions. Like Herceptin -- the drug that miraculously cuts recurrence upwards of 50 percent for positive women like me. I was a lucky recipient of this drug. And the pharmacist who mixed the drug for all 17 of my infusions tells me it's really a good thing I have this HER2 problem -- because the drugs created to attack the problem may just cure me of my disease.

So in an odd turnabout -- from bad luck to good fortune -- I am not so sad my tumor was aggressive. It means there are bonus treatments for me. And if my cancer comes back and Herceptin no longer works, there is another drug called Tykerb. And now the Army is leading its own breast cancer vaccination study. The focus -- HER2.

Early study results from Walter Reed Army Medical Center in Washington, D.C. suggest a 50 percent reduction in disease recurrence for HER2 positive women who receive a vaccination of AE37.

AE37 targets HER2 and boosts the body's immune system so it can battle the protein before it stimulates growth. It's similar to Herceptin, but the activity of AE37 stimulates a patient's own immune system to recognize the cancer target rather than interacting with the target directly.

Should the Food and Drug Administration decide to support this study, it will proceed to Phase 3 testing, which includes a much larger pool of participants.

The breast cancer chemotherapy drug Adriamycin is often called The Red Devil. It's red in color and devilish in it's attack on both cancer cells and healthy cells. After her own personal attack by this drug, Katherine Russell Rich wrote a book, and she called it The Red Devil: To Hell with Cancer -- and Back. It's her account of how she got sick at the age of 32 with a relentless form of breast cancer. Although she was given just a short period of time to survive, Rich conquered cancer. And years later, she is alive and well. And she has discovered -- by mere coincidence -- that her book years ago inspired a group of women in Baltimore who are helping breast cancer patients through kind deeds. They foot the bill for transportation costs, housecleaning, and massage. They pick up and deliver medications. They gather and hug and eat. They take strolls. They call themselves The Red Devils.

Rich only found out about The Red Devils support group when a friend noticed a mention of the group in a newspaper. She informed Rich who visited the group's website. What she found took her breath away.

It seems a woman named Lark Schulze had at one time been desperate to learn about young women with stage IV breast cancer -- the same stage her 30-year-old daughter faced -- and she could not find any helpful resources. Until she came across Rich's book and poured herself into one woman's story. Moved by Rich's words, she tried to locate her, with no luck. So she took what she gathered from the book and after losing her daughter 19 months after diagnosis, became a founding member of a powerful support group -- The Red Devils -- in late 2002.

Despite failed attempts at finding Rich, Schulze says Rich changed her life. And now that the women have connected, Rich says Schulze has changed her life. At first Rich was afraid to be drawn into Schulze's world. But with a hunger to understand breast cancer from a mother's perspective, Rich took the plunge. She talked to Schulze, visited her, strolled with her, and soon the hard lump she'd carried in her stomach for so long began to soften as she connected in a deep and bizarre way with a woman she had inspired -- a woman she had never before known.

Researchers from the National Cancer Institute announced Thursday that two cancer patients with rapidly growing melanoma were successfully treated with gene therapy. The patients -- both men -- were given immune system cells from their own blood that were engineered to attack their tumors. This took place 18 months ago -- and they are still surviving with no evidence of cancer. This success comes after a three-decade effort by surgeon Steven Rosenberg to find ways to use the immune system to fight cancer. This approach is not always successful, however, and 15 other patients who got this same treatment did not survive. Still, Rosenberg believes this small-scale success is proof that the principle of gene therapy can work. And others agree -- calling his work an important landmark, even though the response rate of two out of 17 is not ideal.

Rosenberg does not claim the two surviving patients are cured. If they survive for five years, he might classify them as possibly cured -- but even after five years, cancer can come back. He does consider this a huge breakthrough for these two men who are still alive and well. And he says he has every expectation that he can get the process to work even better in the future.

Coletta Barrett believed her stomach pains were caused by a gall bladder attack after eating greasy fried food. She excused a tightening in her lower abdomen as irritable bowel syndrome, and she explained blood in her stool as a response to stress. Only after a referral to a gastroenterologist led to a colonoscopy did she learn that the upper portion of her colon was almost completely blocked by a large tumor -- a cancerous tumor. Barrett was diagnosed with colon cancer. Her colonoscopy saved her life.

Barrett never once predicted she might have colon cancer. She thought the disease mostly struck older people. She was just 42. Screening tests are not even recommended until the age of 50. She had no family history of this cancer and had no typical risk factors associated with the disease. She did not smoke, was not overweight, and drank very little. But she did in fact have colon cancer -- shocking as it was -- and doctors believed her tumor had been growing for 18 months before detected. Fortunately, Barrett learned that her cancer had not spread. And she learned a few other things that she now shares as advice -- from her survivor point of view. These tips come from an article about Barrett in the August 1 Women's Day magazine.

• Barrett says, "know your body." And don't ignore or dismiss any changes that occur.
• Don't let embarrassment stop you from seeking help. Some symptoms can be difficult to discuss -- such as change in size and frequency of bowel movements, bloody stool, cramping, and bloating -- but still ask your doctor about them. Early detection is critical, she says.
• If diagnosed with colon cancer, learn as much as you can about the disease -- a well-informed patient has a better chance at a better outcome.

Barrett offers sound advice. And I think it is global advice. Knowing your body, discussing symptoms, and education after diagnosis are key for anyone. For everyone.

To your good health! To a great week!

New birth control pills and contraceptives are already on the market -- or about to be released -- that allow women the option of ending monthly menstruation for good. This option is becoming increasingly popular with women at both the beginning stage and ending stage of their reproductive life.

For women who suffer greatly each month with the physical pain and emotional upsets that can occur during periods, this might be a good option. For other women, it might be a matter of convenience and a way of improving sex life. If you are not actively attempting to get pregnant, this seems like a reasonable option in eliminating periods that do not seem to serve a practical purpose. As I understand it, the pills are far safer than the contraceptive pills of the past, with much lower doses of estrogen and progestin. However, it is still a birth control type pill, and the warnings remain the same. If you are over 35 and smoke, you are advised not to use it. If you are a cancer survivor diagnosed with cancers fueled by hormones, you are advised not to use this method of controlling monthly menstrual cycles. This pill still increases the risk of heart attack, stroke and blood clots.

On the other side of the coin -- according to research -- these birth control type pills might lower risk of endometrial and ovarian cancer. But, hormones operate in the body on so many complex levels, and regulate so many other systems within the body, I do not know that scientists understand the complexities enough to tell women that halting a hormone process for an indefinite amount of time by manipulating estrogen and progestin is safe for long-term health. Especially when it comes to cancers that are hormone-driven.
