What Biden's Cancer Diagnosis Means — A Doctor Breaks It Down With Katie
Dr. Nelson: I feel for anyone who hears the three terrible words 'you have cancer.' Their world, and all of their plans, are turned upside down as they worry instead about what may be in store for them, wondering how the cancer can be treated, how well treatment might work, and what side effects they might confront.
The reports do suggest that he has metastatic prostate cancer, which is a life-threatening condition capable of causing significant bone pain. His doctors may make use of several treatment approaches, particularly lowering the male hormone testosterone and interfering with its propensity to fuel cancer growth and progression, and radiation therapy aimed at sites of disease. Several other treatments can also be used if necessary.
Screening for prostate cancer using blood tests for prostate-specific antigen can save lives, allowing prostate cancer to be diagnosed at an early stage when surgery or radiation therapy are most effective. Most recommendations are that PSA screening be considered only after consultation with a physician about risks and benefits, and if elected, start at age 50 years (or earlier for Black men or men with a family history of prostate cancer).
When to stop screening can be a vexing question. The US Preventive Services Task Force recommends against routine screening of men after age 70 years, but many men and their doctors continue to pursue PSA screening through the 70s and beyond, taking into consideration other health problems, life expectancy, etc.
Finally, even despite a routine screening regimen, particularly aggressive cancers can arise in between planned screening tests.
The Gleason score is assigned by a pathologist who diagnoses prostate cancer by examining prostate biopsy specimens under a microscope. The score (named for a pathologist named Donald Gleason, who worked at the Minneapolis VA Medical Center in the 1960s) ranges from 6 to 10 and reflects the pattern of growth seen by the pathologist, with higher scores indicative of more aggressive cancer behavior.
The side effects associated with antagonizing the actions of the male hormone testosterone include hot flashes, loss of libido, fatigue, diminished muscle mass and strength, osteoporosis, and increased risk of cardiovascular disease.
The major side effects associated with prostate radiation therapy are a result of damage to nerves that run along the prostate and are responsible for erections, and of damage to the rectum. Prostate surgery, when appropriate, also risks damage to nerves needed for erections, along with risks of urinary incontinence.
From what has been reported, President Biden's prostate cancer can definitely be treated, with the promise of keeping his prostate cancer under control for many months, or hopefully even longer.
Autopsy studies conducted on men dying from other causes suggest that more than half of men harbor cancers in their prostates by the time they get into their 80s. These days, 1 in 8 men receive a diagnosis at some point in their lives, while about 1 in 44 die of the disease.
One of my old mentors, the late Donald Coffey, used to argue that the key screening and diagnosis challenge is to find the aggressively behaving disease, which he called the 'tigers,' early enough to allow treatment for cure, while leaving what he called the 'pussycats' alone. This has been slowly improving: Prostate MRI is now more frequently used to ensure that prostate biopsies are aimed at the more aggressive lesions in the prostate so that they aren't missed.

Deadly NYC Legionnaires' disease outbreak fueled by negligence, lawsuit says
Civil rights attorney Ben Crump has filed lawsuits against two construction companies over what he called a "completely preventable" outbreak of Legionnaires' disease that has killed five people and sickened more than 100 others in New York City. Legionnaires' disease is a severe pneumonia caused by a type of bacteria called Legionella, which grows in warm or hot water, according to the Centers for Disease Control and Prevention. An outbreak of the disease, which began on July 25, has been clustered across five zip codes in Central Harlem. The city health department said the outbreak is linked to cooling towers, heat exchangers that use fans and water to cool down buildings. On Aug. 14, health officials confirmed that 12 cooling towers at buildings including NYC Health + Hospitals/Harlem tested positive for the Legionella bacteria. Crump and other attorneys filed complaints on behalf of two construction workers who were hospitalized with Legionnaire's disease in July after working near the hospital in Harlem, according to a news release. Crump said the legal team has also filed a notice of claim and intend to sue the city as well. "It is believed that the cooling towers at Harlem Hospital were filled with rainwater after several large July storms," the release said. "The water was left untreated, which permitted bacteria to spread causing workers at the site to become sick." Construction companies, city accused of negligence Crump accused Skanska USA Building, Inc., Rising Sun Construction LLC and the city of negligence at a news conference on Aug. 20, announcing the lawsuits. The attorneys said the construction companies were put on notice about the possibility of Legionella bacteria through bulletins after the storms, but failed to take action to keep those working near the hospital safe. "When corporations cut corners, tragedies like this happen. Preventable tragedies, unnecessary tragedies," Crump said. Crump said the lawsuit is seeking not only compensation for the workers but also accountability and answers about why this outbreak occurred in Harlem — a historically Black neighborhood in Upper Manhattan. Skanska and Rising Sun did not immediately respond to a request for comment from USA TODAY. Christopher Miller, a spokesperson for NYC Health + Hospitals, said in a statement the agency has "one of the most rigorous cooling tower safety and inspection programs, exceeding City testing and cleaning requirements." "We inspect towers every day; further, we look for legionella weekly instead of the required every 90 days," the statement said. "We continue to work with our cooling tower maintenance firm and the NYC Health Department to best serve our patients and the Harlem community.' When asked about Crump's claims about the source of the outbreak, a spokesperson for the city's health department said the investigation is ongoing. "Molecular testing may help us determine which cooling tower — or cooling towers — were the source of the bacteria in the Central Harlem cluster," spokesperson Chantal Gomez said in a statement. "The Public Health Lab is still determining a match through DNA sequencing and we expect final results soon.' Electrian describes gasping for air while hospitalized with Legionnaire's Nunzio Quinto, a union electrian who worked at a ground-up construction of the NewYork City Public Health Laboratory, a 10-story facility adjacent to the hospital complex, said he thought he had food poisoning when he first started feeling lethargic in late July. Quinto said his family took him to the hospital, where he was immediately diagnosed with Legionnaire's disease. He suffered breathing problems, pain and internal bleeding during a five-day stay in the hospital, but said his coworkers weren't notified of his illness. "I want answers to what's going on. I can't have a safe place to work? This is New York City," Quinto said at the news conference.

How does Legionnaires' disease spread? What to know about NYC outbreak
NEW YORK − Health officials are still finding cases in one of the city's largest Legionnaires' disease outbreaks in years as they continue monitoring Harlem cooling towers suspected of sickening more than a hundred people. On Aug. 19, New York City health officials identified a fifth person died before mid-August from the central Harlem outbreak of Legionnaires' disease, which is a severe type of pneumonia. Since the outbreak began in late July, 108 people have been identified as sickened, according to the New York City health department. The outbreak is concentrated across five ZIP codes in central Harlem, a historically Black neighborhood in Manhattan. New cases continue to decline as officials remediate cooling towers suspected to harbor the Legionella bacteria that causes the disease. When was the last large Legionnaires' outbreak in NYC? The health department identifies cases each year, sometimes resulting in death. The city saw its largest recent outbreak in 2015. Then, 138 cases and 16 deaths were linked to a single cooling tower in the South Bronx, just across the Harlem River from the Harlem neighborhood. A more recent outbreak in 2022 in the Bronx's Highbridge neighborhood saw 30 people sickened, a city health department report said. Decades earlier, a large outbreak in Pennsylvania gave Legionnaires' disease its name. In 1976, an outbreak at an American Legion veterans organization state convention in a Philadelphia hotel infected 180 people and killed 29. How does Legionnaires' disease spread? The bacteria − found naturally in freshwater − grows in warm or hot water, according to the Centers for Disease Control and Prevention. The disease doesn't spread between people, but from mist containing bacteria that people inhale, city health officials said. Without maintenance, water systems, such as hot tubs, cooling towers, hot water tanks or big plumbing systems give the bacteria ideal places to grow. CDC estimates nine in 10 outbreaks were caused by preventable problems with effective water management. In New York, officials suspect a dozen cooling towers, used atop 10 larger buildings to control the temperature of cooling systems using fans and water as heat exchangers, caused the current outbreak. The cooling towers sprayed mist containing from the tops of buildings. Legionnaires' disease doesn't spread by drinking water, or from cooled air from air conditioners. Window AC units, ubiquitous on many buildings in New York, also aren't a risk for bacterial growth, since they don't use water to cool the air. City health officials have sampled and tested water from the cooling towers and treated affected buildings in the five ZIP codes (10027, 10030, 10035, 10037 and 10039). What are Legionnaires' disease symptoms? Most people exposed to the bacteria don't develop Legionnaires' disease. The risk to most people in central Harlem ZIP codes is low, but people who live or work in the area and have flu-like symptoms are urged to seek care right away, city health officials said in an Aug. 6 notice to residents. As a severe form of pneumonia, symptoms include fever, chills, muscle aches and cough, city health officials said. People can also get headaches, fatigue, loss of appetite, confusion or diarrhea. Symptoms develop between two and 10 days after exposure, but it can be up to two weeks. People at higher risk include those ages 50 and older, smokers, have chronic lung disease and have weakened immune systems from a condition or medication. Possible complications can include lung failure and death, with about one in 10 people who get sick dying from the disease due to complications from illness, CDC said. The disease is easily treatable with antibiotics. If people develop symptoms, they should seek medical care right away. What is risk ahead? With hotter, more humid temperatures in a warming climate, Legionnaires' disease is a growing health concern. CDC data shows the condition is becoming more common in recent decades. In New York, outbreaks tend to oscillate between predominantly lower income Black and Latino neighborhoods, a former health official previously told USA TODAY.
