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.

Some scientists believe that surgery to remove a breast tumor may actually help the cancer spread and have recently reported that this same belief may be the exact reason black women are more likely to die of breast cancer.

There is apparently a widespread belief in parts of Africa and the United States that removing a tumor hastens death.

"I must say that I am sure there is more to this than just a myth," said Michael Retsky of Children's Hospital and Harvard Medical School in Boston, who shares his opinions in the International Journal of Surgery.

Retsky still urges any woman with breast cancer to have her tumor removed. And he says chemotherapy is such standard practice for any cancer threatening to spread. It's a safety net of sorts to catch the cells that get away. So if surgery causes cancer to spread, then in theory, chemotherapy should stop the spread.

Retsky, who is not suggesting any change in clinical practice, thinks the subject needs far more research. American Cancer Society experts, who tend to question this theory, agree.

"Whether or not the theory is correct, I have difficulty with the logic that they employed to get there," said oncologist Dr. Len Lichtenfeld of the American Cancer Society who says women should never delay treatment for breast cancer.

Retsky believes that perhaps surgery, by wounding the body, causes it to produce growth factors that fuel the growth of other, tiny tumors. Or maybe a primary tumor secretes some sort of factor that holds the other tumors in check. When the main tumor is removed, the smaller tumors grow.

But it could be that surgery does not cause a spread at all – and that any belief of this nature has no connection with breast cancer tendencies in black women. It may be that black women just have a genetic predisposition for more aggressive forms of the disease.

One or more extra or missing chromosomes can both fuel tumor growth and act to suppress tumor growth, according to University of California, San Diego (UCSD) School of Medicine researchers.

Heralded as a discovery that solves a 100-year-old genetic puzzle because the hypothesis was first suggested by German biologist Theodor Bover that long ago, researchers sought to determine if the wrong number of chromosomes contributed to tumor growth, or was a consequences of damage in cancerous cells.

While studying aneuploidy -- which is what the occurrence of one or more extra or missing chromosomes is called -- in mouse models, the researchers found that the same genetic mechanism that promotes tumor growth can slow tumor growth.

"This study opens up a whole series of potential therapeutic targets for cancer," said Beth A.A. Weaver, of the Ludwig Institute for Cancer Research and UCSD Department of Cellular and Molecular Medicine, the study's first author. "By increasing the level of genetic damage, we can kill tumor cells."

I'm headed for a Saturday morning workout with my fitness trainer. For one hour, I will physically challenge my body and emotionally charge my spirits. I will sweat and pant and if I am required to do the inner thigh exercise, I will scream. I will also whine -- it's in my nature -- and I will push, pull, bounce, balance, lift, squat, lunge, and run until it's quitting time. I will fall short on some of my exercise expectations. And I will surprise myself and exceed others. In the end, I will feel accomplished, strong, motivated, and ready to tackle the day.

I'm making a comeback. I have come back from the depths of cancer and all of its accompanying treatment, and I have invited this powerhouse of a girl to transform me. She has accepted the challenge -- and she has helped me evolve from a weak, shaky, dizzy cancer patient to a semi-strong, 5K-running breast cancer survivor with biceps that are almost visible at a close distance.

This spunky fitness girl -- also an accomplished kick boxer, wife, and mom of two little ones -- has accepted another one of my challenges. I asked her to share some of her health and fitness expertise so that we all may reap the benefits. And so she kindly extracted some important tidbits from her vast library of knowledge and concisely crafted the responses that follow.

Take it from Fitz Koehler -- exercise and healthy eating habits are key for survival. For all of us. Cancer survivors included.

Why is fitness important for everyone?

100% of the population needs to exercise in some way. For the most part, if you're not working to get stronger, you're going to get weaker. Whether it's tummy time as an infant, gym class as a kid, weight training as an adult, or short walks as a senior, in order to live well and live long, we must eat well and exercise. Plus, a fit lifestyle prevents so many horrible ailments and diseases -- heart disease, some cancers, diabetes, GERD. Who wants any of that?

An announcement last Wednesday revealed an overall decline in cancer death rates -- probably due to reduced exposure to tobacco, early detection, and better treatment. But the announcement also revealed a surprising jump in cases of thyroid cancer for women.

Between the years 1981 and 1993, incidence rates among women climbed 2.2 percent each year. Between the years 1993 and 2000, they rose 4.6 percent per year. And between 2000 and 2003, there was a 9.1 percent increase each year. This could be a result of better diagnosis but scientists are wondering if there is an unknown risk factor contributing to this startling finding. And it will take at least two more years to determine whether this is a random fluctuation or a true trend. The rate of thyroid cancer in men has also increased but not as much as for women.

The silver lining in this cancer cloud is that trends -- such as those showing increases in cancer incidences and death rates -- often fuel the fight against cancer because researchers are alerted to look for causes which ultimately results in better detection and better prevention.

BBC News is reporting that the conflict between Hezbollah and Israel has caused a massive oil spill off Lebanon's coastline that could take ten years to clean up and poses a threat of increased cancer risks for people living in the region. The spill was caused by the Israeli bombing of the Jiyyeh power station.

Yacoub Sarraf, Lebanon's environment minister, stated that they cannot begin to tackle the problem until the conflict ends. "We cannot get equipment, companies, labor or know-how to handle the problem," he said until the safety of technical teams can be guaranteed.

Marine experts from Inforac, an organization with links to the United Nations Environment Program (Unep), said the spill of fuel oil was a "high-risk toxic cocktail made up of substances which cause cancer and damage to the endocrine system." The experts warned that the first people at risk from the toxic spray at the time of the bombing were the two million inhabitants of Beirut.

Experts are comparing the oil spill to the Erika tanker oil spill off the coast of France and speculated that the Lebanon oil spill could end up being as devastating as the Exxon Valdez disaster.

It's hard to describe the feelings that overwhelmed me during my bad days with cancer. I could call them consuming and crushing and sickening and frightening and crippling and still not completely cover all the bases. It's much easier to describe the feelings that overwhelmed me on my good days with cancer. I felt -- and still mostly feel this way -- happy and spunky and motivated and invigorated and fulfilled. And I felt loved -- because most of my bad days were turned around by the love of others. It was like clockwork. When I needed it most, a surprise awaited me in my mailbox or my inbox or on on the other side of my front door or on my front porch. These surprises strengthened me on my bad days -- and sometimes beyond the bad days. They still help me really -- because my memory of how they saved me from days of despair continues to fuel my good days. And here are seven of my special surprises.

Each year 350 children are diagnosed with a rare form of thyroid cancer. What are the random odds that three teenagers who live within a few miles of each other would be diagnosed with this particular cancer?

Cincinnati News 5 is reporting that the parents of these teens are asking this question and speculating that it might have an environmental cause. The parents wonder -- could a pipeline that runs through town carrying jet fuel have leaked into the ground water -- or is the Edgewood Middle School all three teens attended built on a site that is contaminated?

The parents have no proof, they have no answers and no one seems to want to help them find out what the problem might be that has led to the unusually high concentration of thyroid cancer cases to be diagnosed in one small group of teens living in such close proximity to one another.

According to one of the parents, all they want is to have water samples tested and they feel their requests have been ignored for the last 18 months. Now city officials plan on meeting with the parents next week to discuss their concerns.

It is frustrating to be ignored when you are asking for help to find the cause of circumstances that appear suspicious. It seems rather than let this matter drag out as long as it has, it would have been so much easier for officials to just look into it when it first came up. At least the parents would not have been left to draw their own conclusions.
