Biden's aggressive form of cancer has sapped him of his strength, and the toll has forced him to cancel several speaking engagements he had scheduled for the end of the year.

Before he dropped out of the 2024 election and made way for Kamala Harris, speaking arrangements were made for him at numerous locations, but those have now all gone down the tubes.

Most recently, Biden was spotted with a giant bandage hiding a vicious scar from a delicate cancer surgery. Officials revealed the massive gash above his right eye was the result of surgery to remove skin cancer lesions.

Last month, his spokeswoman, Kelly Scully, downplayed the Mohs surgery, which removed a potentially deadly malignant lesion and surrounding tissue. The tissue will now be tested to determine if it has spread to other parts of the body, but renowned internist Dr. Stuart Fischer, who has not treated Biden, told RadarOnline.com he believes the politician is in a potentially dire situation.

"With so many medical problems, his longevity is definitely in question, and reports of dementia make him even more vulnerable," Dr. Fischer explained. "Melanoma is notorious for being unrecognized and dangerous."
