Civil rights icon Dorothy Height's eulogy was the third that President Obama has delivered since taking office. The others were for the late Sen. Edward Kennedy (D-Mass.) and the miners who died this month in a West Virginia mine collapse.
Kennedy's funeral allowed the president to embrace the senator's legacy and pay homage to a key supporter. Honoring the miners enabled the president to connect with a suffering working-class community and show empathy for a bloc that did not back him at the polls.
Height's services were different, packed with both historical references and light moments. Before taking the pulpit to speak, Obama sat next to his wife, bobbing his head as gospel artist BeBe Winans sang "Stand." Obama smiled as he listened to friends tell stories about Height daring to play basketball for her school team long before it was acceptable for women to do so.
Poet Maya Angelou offered a reading and Camille Cosby also paid tribute to Height, who led the National Council of Negro Women for decades and marched with the Rev. Martin Luther King Jr.
Obama praised Height as the "godmother of civil rights," becoming a stalwart of the movement even at personal risk. He said she "deserves a place" in our history books and America's memory and noted that anyone who had lived long enough to have an 88-year old nephew had "lived a full life."
Height was 98 when she died last week.
Obama spoke of the period in which Height was raised, when lynching was still commonplace, black people were legally denied opportunities and slavery was still a fairly recent memory for some.
Then he placed himself as an heir of Height's work, as he has often done, thanking civil rights leaders for being the "Moses generation" that led their people out of the desert. Obama refers to his generation as the "Joshua" generation, referring to the biblical successor to Moses, leading his people to the promised land.
"It's because of her that Michelle and I are here," Obama said to applause from those who had gathered to honor Height.

Daily Calcium and Vitamins Linked to Lower Breast Cancer Risk
April 18, 2010, 2:01 PM EDT
By Ellen Gibson
April 18 (Bloomberg) -- Calcium doesn’t just build strong bones, it may fight cancer too, a study said.
Researchers at the Ponce School of Medicine in Puerto Rico reported that women who took calcium had a 40 percent lower risk of getting breast cancer, while those getting multivitamins showed a 30 percent reduction in risk. The new findings, from a study of 744 women, were presented today at the meeting of the American Association for Cancer Research in Washington.
The data contradict results of a December 2008 trial that showed no reduction in cancer risk from vitamin supplements. The scientists attributed the calcium benefit seen in today’s study to its effect on what they called DNA repair capacity -- the biological process by which cells patch up damaged DNA that otherwise may cause cancer. Today’s report suggests women may boost their cellular defenses with dietary changes and long-term use of supplements, they said.
“The importance of this finding is that now we can monitor breast-cancer risk using DNA repair capacity,” said Manuel Bayona, a professor of biostatistics and epidemiology at Ponce School of Medicine and an author of the paper. “We believe that all women should be taking vitamins and supplements. Now we can tell if that regimen is really doing its work in reducing the risk.”
A good analogy, Bayona said, is the management of heart disease. Just as doctors track patients’ cholesterol and modify it with changes in diet or drugs, they could use blood tests to monitor the DNA repair ability of women at elevated risk for breast cancer and tweak it using dietary supplements.
Vitamin Intake
The study included 278 women with breast cancer and 466 healthy controls. They were given a questionnaire that included several questions about their current and past intake of specific vitamins and minerals. The researchers also took blood samples to measure DNA repair capacity, and the cancer patients were compared with the controls on several dimensions.
The researchers said that the protective effect of calcium is due to its impact on DNA repair. Previous studies have demonstrated calcium’s cancer-blocking benefit without explaining the mechanism of action. A study in June 2007 in the American Journal of Clinical Nutrition from researchers at Creighton University School of Medicine found that women taking calcium and vitamin D showed a 60 percent reduction in cancer risk.
Repairing Damage
The relationship between vitamin supplements and cancer risk is more complicated. Vitamins prevent and repair the cancer-causing damage done by free radicals, the highly reactive atoms that can wreak havoc on cells, according to Jaime Matta, a professor of pharmacology and toxicology at Ponce School of Medicine and a co-author of the study.
Some recent research suggests that vitamin supplements have no protective power against cancer. One study of 7,627 women in the Journal of the National Cancer Institute in December 2008 found that women who took vitamins C and E and beta carotene had the same risk of cancer diagnosis and death as those who didn’t. Research published in the Journal of the American Medical Association in January 2009 showed that vitamin E may raise the risk of prostate cancer.
In today’s study, other factors found to be associated with higher rates of breast cancer were older age, a family history of breast cancer, and no breastfeeding, according to the paper.
Daily Regimen
In follow-up research, the scientists will try to find the ideal daily vitamin regimen for a woman, according to her age and other characteristics, Bayona said in a telephone interview on April 12. He plans to ask more detailed questions about participants’ diets and vitamin intake and to take blood samples to confirm the levels of different nutrients in their bodies.
“People tend to be on the very low end of antioxidant and vitamin intake from veggies and fruit,” Matta said in an interview. “The good thing about taking vitamins is that there’s no downside in terms of risk. This opens the door to very cost-effective prevention.”
The research was funded by the National Cancer Institute’s Center to Reduce Health Disparities in Rockville, Maryland, and the National Institute of Health’s Minority Biomedical Research Support program in Bethesda, Maryland.
