The flu is what caused Australian pop star Kylie Minogue to cut a live London show short on Saturday. Her cancellation had nothing to do with breast cancer, her spokesman says.

Minogue, who was diagnosed with breast cancer in May 2005, has endured both surgery and chemotherapy and is back on the Showgirl Homecoming Tour she had to postpone just after her diagnosis. The revival of her tour represents Minogue's cancer comeback -- and this recent health setback is nothing more than a temporary bout with the flu. It is reported that several of her band members also have the bug.

Minogue, 38, kicked off the British leg of her tour on New Year's Eve. She has already played seven dates at London's Wembley Arena.

I will visit my oncologist on Monday for my every-three-month check-up. It's the recurring appointment that will appear on my calendar until I hit the five-year-survival milestone. I am three years away.

It's the appointment that consumes at least half of my day due to endless waiting -- waiting for a parking spot, waiting in the lobby, waiting in the exam room, waiting to pay. It's the appointment that officially begins with the drawing of my blood for lab work, continues with a check of my vitals, proceeds with a history review and physical exam with a medical student. It's the appointment that brings me face to face with the man who prescribed my treatment, the man who offers me strategies for living beyond treatment, the man who helps keep me alive. My oncologist.

And so I am preparing for this visit in the same exact way as I always do. I set aside a large chunk of time for this time-consuming extravaganza. I think a lot about the lab work and wonder if something suspicious will surface. I think a lot about the physical exam and wonder if an enlarged lymph node or mass in my breast will be discovered. And I think a lot about what I want to ask -- because this is my only very own allotted time for unraveling the mysteries of cancer with the man who knows the topic like no one else I know.

On Monday, I will ask a few questions. I will ask about tumor markers, about why I am not tested for these indicators of tumor growth, a standard option for my co-writer and co-cancer survivor Kristina Collins. I will ask about Zoloft, about how long I should continue taking this anti-depressant and how to best wean myself from this drug when the time comes. I will ask about the flu shot, about whether or not I can get one during this same appointment.

And that's all. For now. Until three more months pass and my calendar tells me it's time to return for this recurring appointment that takes me closer to the five-year mark.

Although researchers have considered the possibility that the bark of the White Birch tree might contain a compound, known as betulinol, with the ability to fight prostate cancer, until recently there was no way to test it because they did not know how to make the compound water-soluble.

Now that Weill Medical College of Cornell University researchers have solved that problem, laboratory tests on mice are showing it is indeed effective in killing prostate cancer cells.

"Years of research appear to have paid off, and now animal tests on this potential anti-cancer agent can finally proceed. Already, in mouse studies, we've found that our water-soluble compound - called Boc-lysinated-betulonic acid -- has achieved up to 92 percent inhibition of prostate tumor growth compared to controls," states lead researcher Dr. Brij Saxena.

While the study into the cancer-fighting properties of the White Birch tree might be new, the White Birch tree has a history of medicinal uses. According to the Living Memorials Project website White Birch tree information page, Native American Indians used the leaves and bark of the tree as a tea to treat fevers, stomach upset, and rheumatism. The bark was boiled to make poultices for minor wounds, and an oil made from the bark to treat bladder infections, rheumatism, gout and nerve pain. In Europe, the leaves were used to treat skin rashes, hair loss, rheumatic complaints, and to purify the blood. Birch tar oil was used to treat chronic skin diseases.

The Phytochemical and Ethnobotanical Databases of United States Department of Agriculture includes information on betulin and betulinic acid as showing that it inhibits cancer, and the compound is also known to be anticarcinomic; anti-flu; anti-inflammatory; antiviral; and a prostaglandin-synthesis-inhibitor.
