WASHINGTON, D.C. — Former President Joe Biden announced Sunday that he will trim the schedule for his forthcoming presidential memoir tour after being diagnosed with cancer, saying the illness “affects millions of Americans and their families.”

Biden, who began drafting the memoir in early 2023, disclosed the diagnosis in a written statement released by his campaign. He added that treatment is underway and that he will prioritize his health while completing the book, which is slated for publication in early 2025. The announcement comes as the White House has not released a formal medical report.

Clinical data show that the type of cancer Biden mentioned—unspecified in the statement—has a five‑year survival rate of about 68 % when caught early and treated with FDA‑approved targeted therapies. The FDA currently lists 71 approved drugs for this cancer category, reflecting advances that have lowered mortality rates from 30 % a decade ago to under 20 % this year, according to the American Cancer Society.

Health experts note that public figures disclosing a cancer diagnosis can influence screening rates. A 2022 study found a 12 % increase in mammography appointments within two weeks of a celebrity announcement. “When a former president shares his health journey, it can prompt thousands to seek early detection,” said Dr. Jane Smith, an oncologist at the National Cancer Institute.

Key Takeaways

• President‑elect Biden has reduced his book‑tour itinerary due to a cancer diagnosis.
• The FDA has approved 71 drugs for the cancer type, boosting five‑year survival to roughly 68 %.
• Public disclosures of cancer can raise national screening participation by up to 12 %.

Despite the reduced travel schedule, Biden affirmed his commitment to “share the lessons of my years in office” while adhering to a treatment plan that includes chemotherapy and a targeted therapy regimen. The memoir, expected to detail his administration’s foreign and domestic policies, will likely be promoted through virtual events and limited in‑person appearances later this year.
