President Grover Cleveland

In the summer of 1893, President Grover Cleveland disappeared for four days to have secret surgery on a yacht. It was the beginning of his second term as president and the country was entering a depression, a delicate time in which a president's health was inextricably linked to that of the nation. So Cleveland decided to keep the surgery a secret.

Shortly after he took office for the second time in 1893, he noticed a little bump on the roof of his mouth had grown quite large in the summer.It was diagnosed as cancer.
