President Joe Biden on Monday channeled John F. Kennedy on the 60th anniversary of JFK's moonshot speech, highlighting Biden administration efforts aimed at "ending cancer as we know it."

The president traveled to Boston on Monday to draw attention to a new federally backed study that seeks to validate using blood tests to screen against multiple cancers — a potential game-changer in diagnostic testing to dramatically improve early detection of cancers. 

"These blood tests could lead to less-invasive cancer detection tools will save lives," Biden said. 

His speech at the John F. Kennedy Presidential Library and Museum comes as Biden seeks to rally the nation around developing treatments and therapeutics for the pervasive diseases that the Centers for Disease Control and Prevention rank as the second-highest killer of people in the U.S. after heart disease. Biden hopes to move the U.S. closer to the goal he set in February of cutting U.S. cancer fatalities by 50% over the next 25 years and to dramatically improve the lives of caregivers and those suffering from cancer.

In 2022, the American Cancer Society estimates, 1.9 million new cancer cases will be diagnosed and 609,360 people will die of cancer diseases.

Biden said that Kennedy "established a national purpose" when he called on Americans to support the mission to the moon six decades ago, "and he succeeded."

"Now in our time, on the 60th anniversary of his clarion call, we face another inflection point. And together, we can choose to move forward with unity, hope and optimism," Biden said. 

The issue is personal to Biden, who lost his adult son Beau in 2015 to brain cancer. After Beau's death, Congress passed the 21st Century Cures Act, which dedicated $1.8 billion over seven years for cancer research and was signed into law in 2016 by President Barack Obama.

Obama designated Biden, then vice president, to run "mission control" on directing the cancer funds as a recognition of Biden's grief as a parent and desire to do something about it. Biden wrote in his memoir "Promise Me, Dad" that he chose not to run for president in 2016 primarily because of Beau's death.

Biden on Monday said world leaders often ask him about the cancer initiative he helped launch, and he called it a core part of his presidential agenda.

"This Cancer Moonshot is one of the reasons why I ran for president," he said. "Because we know this: cancer does not discriminate, red and blue. It doesn't care if you're Republican or Democrat. Beating cancer is something we can do together."

He also called on cancer patients and their families to share their experiences to help push for change, comparing it to a years-long push for health benefits from veterans and their families that led to a critical bill's passage in Congress this summer.

Despite Biden's attempts to hark back to Kennedy and his space program, the current initiative lacks that same level of budgetary support. The Apollo program garnered massive public investment — more than $20 billion, or more than $220 billion in 2022 dollars adjusted for inflation. Biden's "moonshot" effort is far more modest and reliant on private sector investment.

Still, Biden has tried to maintain momentum for investments in public health research, including championing the Advanced Research Projects Agency for Health, modeled after similar research and development initiatives benefiting the Pentagon and intelligence community.

On Monday, Biden announced Dr. Renee Wegrzyn as the inaugural director of ARPA-H, which has been given the task of studying treatments and potential cures for cancers, Alzheimer's, diabetes and other diseases. He also announced a new National Cancer Institute scholars' program to provide resources to early-career scientists studying treatments and cures for cancer.

Experts agree it's far too early to say whether these new blood tests for finding cancer in healthy people will have any effect on cancer deaths. There have been no studies to show they reduce the risk of dying from cancer. Still, they say setting an ambitious goal is important.

Scientists now understand that cancer is not a single disease, but hundreds of diseases that respond differently to different treatments. Some cancers have biomarkers that can be targeted by existing drugs that will slow a tumor's growth. Many more targets await discovery.

"How do we learn what therapies are effective in which subtypes of disease? That to me is oceanic," said Donald A. Berry, a biostatistician at the University of Texas M.D. Anderson Cancer Center. "The possibilities are enormous. The challenges are enormous."

Despite the challenges, he's optimistic about cutting the cancer death rate in half over the next 25 years.

"We can get to that 50% goal by slowing the disease sufficiently across the various cancers without curing anybody," Berry said. "If I were to bet on whether we will achieve this 50% reduction, I would bet yes."

Even without new breakthroughs, progress can be made by making care more equitable, said Dr. Crystal Denlinger, chief scientific officer for the National Comprehensive Cancer Network, a group of elite cancer centers.

And any effort to reduce the cancer death rate will need to focus on the biggest cancer killer, which is lung cancer. Mostly attributable to smoking, lung cancer now causes more cancer deaths than any other cancer. Of the 1,670 daily cancer deaths in the United States, more than 350 are from lung cancer.

Lung cancer screening is helping. The American Cancer Society says such screening helped drive down the cancer death rate 32% from its peak in 1991 to 2019, the most recent year for which numbers are available.

But only 5% of eligible patients are being screened for lung cancer.

"It's tragic," said Dr. Roy Herbst, a lung specialist at Yale Cancer Center.

"The moonshot is going to have to be a social fix as well as a scientific and medical fix," Herbst said. "We're going to have to find a way that screening becomes easier, that it's fully covered, that we have more screening facilities."

Biden on Monday also highlighted provisions in the Democrats' health care and climate change bill that the administration believes will lower out of pocket drug prices for some widely used cancer treatments. He also celebrated new guarantees for veterans exposed to toxic burn pits that cover their potential cancer diagnoses.

Dr. Michael Hassett of Dana-Farber Cancer Institute in Boston, said Biden's goal to reduce cancer deaths could met by following two parallel paths: one of discovery and the other making sure as many people as possible are reaping the advantages of existing therapies and preventive approaches.

"If we can address both aspects, both challenges, major advances are possible," Hassett said.

In breast cancer, for example, many women who could benefit from a hormone-blocking pill either never start the therapy or stop taking it before the recommended five years, Hassett's research has found.

"Those are big gaps," Hassett said. "That's a treatment that's effective. But if many people aren't taking that medication or if they're taking it but stopping it before concluding the course of therapy, then the benefits that the medicine could offer aren't realized."
