I heard today on the radio that there's a shortage of blood supply here in Gainesville, Florida. Reserves are so low there's barely enough blood to last one full day at a time. LifeSouth Community Blood Centers reports about this emergency blood shortage on their website.

"The blood supply stands at less than a one-day supply which has blood center officials very concerned," writes John David Larkin Nolen, LifeSouth's Medical Director. "All eligible residents are asked to give blood. Blood donations haven't kept pace with demand and we've had a very tight supply for the past few weeks. But today several patient situations involving children and adults facing life threatening medical conditions depleted the reserve supplies. We're worried about our overall ability to make sure the patients that need blood will receive what they need during the next few days."

I wish I could donate my blood, but I can't. Until I've been free from cancer treatment for five years, no none wants it. But maybe you can help. Try tracking down your local blood center and see what you can do to help. It may just be the gift that saves a life.

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.

Just before my treatment for breast cancer began and during a consultation about what chemotherapy drugs I was about to receive, my oncologist stepped away from my exam room to check on something. When she returned to the room, she told me that she was determining whether or not I qualified for a clinical trial. I had no idea what this meant at the time. All I knew was what she told me -- that my prognosis was too good at that moment to qualify for anything currently under study. I did not fit a profile for anything. I was not a candidate for a clinical trial.

I now know that clinical trials are a critical component of research -- they validate a drug's success or weakness and they provide hope for many who may be at the end of their treatment rope and need something new to consider. A clinical trial is a comparison of standard treatments to newer treatments in an effort to discover better methods for the diagnosis and treatment of cancer. Doctors, scientists, and other health professionals conduct these tests according to strict guidelines set by the Food and Drug Administration -- which establishes mandatory guidelines to ensure the maximum safety of the patient.

Clinical trials rely on volunteers -- and sadly, there is a current shortage of patients willing to participate in trials. Experts say that, for the past few decades, just five to 10 percent of all cancer patients in the United States have joined a clinical trial. There is an urgent need -- because the demand for willing, eligible participants far exceeds the supply. Some experts are even recommending that the small pool of candidates that does exist be rationed to only the most important cancer studies -- leaving other studies with no hope for completion. There is no good solution in sight. But the reasons for the shortage are becoming apparent. It's not that patients are unwilling to join. It's that they are unaware, uninformed, not even sure this opportunity is possible -- because doctors are not suggesting trials to their patients. Treatment on a protocol is more demanding for doctors than routine medical care. And it costs doctors to submit to a trial. And trials burden doctors with regulations and paperwork. And some doctors worry about litigation if something experimental goes wrong. So they often don't approach the topic -- and the result is that a wonder drug may sit in a dark freezer because there are not enough people to test it. This potential wonder drug may never show promise, may never save a life, may never see the light of day.

So I guess my oncologist was ahead of the game in this matter -- she compared my diagnosis and prognosis with the needs of all available clinical trials and found that there was not match. Had she not done this, I would have never thought to ask about the possibility -- which is exactly what patients should do instead of waiting for a doctor to make the suggestion. Because it may never happen.

What is hanging so toxic in the air? According to the latest data from the U.S. Environmental Protection Agency, benzene from cars and trucks that burn gasoline or diesel fuel. Other toxins causing higher risks for cancer where air pollution is the worst are naphthalene and acetaldehyde -- also from vehicles.
