(CNN) - After weeks of requests, the McCain-Palin campaign released a letter late Monday night from Sarah Palin's doctor pronouncing the Republican vice presidential nominee in "excellent health" with "no known health problems."

Dr. Cathy Baldwin-Johnson, who had been Palin's physician at the Mat-Su Regional Medical Center since 1997, also said the Alaska governor had had a 1992 biopsy for a breast lesion that was found to be benign. She said Palin was on no routine prescription medications, with no known drug allergies, but that no screening tests for heart disease had been performed because those tests were not routine for “young healthy women with no risk factors.”

"Governor Palin is in excellent health and has no known health problems that would interfere with her ability to carry out the duties and obligation of Vice President of the United States of America," said Baldwin-Johnson in the November 3 letter.

Two weeks ago, Palin’s campaign said a summary of the governor’s medical history would be made public before Election Day, though they gave no precise timeframe for the release.

John McCain, Barack Obama and Joseph Biden have all provided details about their medical history.
