Have you figured it out yet?

Well here it is another year and no cure for cancer. So the Race for the Cure has scammed women once again. Maybe these two articles, along with the many on the Leaflady's Women's page will help you learn that cells phones and yearly mammography do help raise your risk for breast cancer, in a system that really does not have an interest in a cure.

"BITTER MEDICINE" - Jean McFarlane of Northwood, Middlesex (UK) found the motor nerves involved in movement had been damaged by radiotherapy for breast cancer. Her left hand is now "like a claw" & it does not work properly. Prof. Jane Maher, a consultant oncologist, predicts more long-term side-effects from radiotherapy treatment. She says that radiotherapy dangers are not properly understood. Side-effects can include bone fractures, hair loss, broken blood vessels, infertility, thyroid problems, congestive heart failure, more cancer, etc.

Chemo has long-term impact on brain function
Chemotherapy causes changes in the brain's metabolism and blood flow that can last as long as 10 years, a discovery that may explain the mental fog and confusion that affect many cancer survivors, researchers said on Thursday.

The researchers, from the University of California, Los Angeles, found that women who had undergone chemotherapy five to 10 years earlier had lower metabolism in a key region of the frontal cortex.

Women treated with chemotherapy also showed a spike in blood flow to the frontal cortex and cerebellum while performing memory tests, indicating a rapid jump in activity level, the researchers said in a statement about their study.

"The same area of the frontal lobe that showed lower resting metabolism displayed a substantial leap in activity when the patients were performing the memory exercise," said Daniel Silverman, the UCLA associate professor who led the study.

"In effect, these women's brains were working harder than the control subjects' to recall the same information," he said in a statement.

Experts estimate at least 25 percent of chemotherapy patients are affected by symptoms of confusion, so-called chemo brain, and a recent study by the University of Minnesota reported an 82 percent rate, the statement said.

"People with 'chemo brain' often can't focus, remember things or multitask the way they did before chemotherapy," Silverman said. "Our study demonstrates for the first time that patients suffering from these cognitive symptoms have specific alterations in brain metabolism."

The study, published on Thursday in the online edition of Breast Cancer Research and Treatment, tested 21 women who had surgery to remove breast tumors, 16 of whom had received chemotherapy and five who had not.

The researchers used positron emission tomography scans to compare the brain function of the women. They also compared the scans with those of 13 women who had not had breast cancer or chemotherapy.

Positron emission tomography creates an image of sections of the body using a special camera that follows the progress of an injected radioactive tracer.

Researchers used the scans to examine the women's resting brain metabolism as well as the blood flow to their brains as they did a short-term memory exercise.

Silverman said the findings suggested PET scans could be used to monitor the effects of chemotherapy on brain metabolism. Since the scans already are used to monitor patients for tumor response to therapy, the additional tests would be easy to add, he said.

Breast cancer is the most common cancer among women, with some 211,000 new cases diagnosed each year, the statement said.
