As of 2011, approximately 18,000 people have received medical treatment for illnesses related to toxic dust from the World Trade Center site. A study of rescue workers released in April 2010 found that all those studied had impaired lung functions, and that 30–40% were reporting little or no improvement in persistent symptoms that started within the first year of the attack. In 2011 a major research study showed significant long term medical and psychological effects among first responders to the World Trade Center site. These effects include elevated levels of

Kitty Gelberg, New York state Bureau of Occupational Health's chief epidemiologist said, "We're not saying they are all World Trade Center related; we're just saying this is what people are dying from." Many of the 55 responders who died from cancer had cancer before September 11, 2001, but most of the cancer patients developed the disease afterward.

Over 57,000 people met the program's initial eligibility requirements. On July 1, 2011, MMTP became a part of the World Trade Center Health Program.

administration announced a reduction of research funding and 20% cut of jobs in the WTC Health Program. The issue caused backlash from both Democrats and Republicans, as the cut would put the health of 9/11 first responders at risk.
After the backlash from Republicans, the funding cuts have been reversed but it is unclear whether the job positions in the WTC Health Program will be rehired. Benjamin Chevat, executive director at Citizens for Extension of the James Zadroga Act, commented on the negative impact of the cut, “We know that members of the program have been adversely impacted by these cuts already, since one staffer terminated was in charge of cancer certifications for the program, which means that there must be growing delays in cancer certifications, delaying care."
Eligibility
The WTC Health Program covers responders who worked or volunteered in the rescue, recovery, or clean up efforts at the World Trade Center site in New York, the Pentagon, or the plane crash site in Shanksville, Pennsylvania. It also provides benefits for people who lived, worked, went to school, attended daycare, or adult daycare in the New York City disaster area after September 11. Responders include members of the Fire Department of New York City who participated in the rescue and recovery effort at the World Trade Center sites, as well as other workers, law enforcement officers, and volunteers who participated in the 9/11 response efforts in New York City. Also included are members of fire and police departments, other workers and volunteers who responded to the 9/11 terrorist attacks at the Pentagon or in Shanksville, PA.
New York City responders include active or retired members of the Fire Department of New York City (whether fire or emergency personnel); Police Department of New York City (whether active or retired); Port Authority Police of the Port Authority of New York and New Jersey; employees of the Office of the Chief Medical Examiner of New York City and other morgue workers involved in handling human remains; workers in the Port Authority Trans-Hudson Corporate Tunnel; vehicle maintenance workers exposed to debris; and other workers or volunteers who assisted in the rescue, recovery, debris cleanup or related services. Members of the New York City Fire Department must have participated in the rescue and recovery effort at any of the former World Trade Center sites (including Ground Zero, Staten Island Landfill, and the New York City Chief Medical Examiner’s Office). Other workers and volunteers must have responded in lower Manhattan, including Ground Zero, the Staten Island Landfill, or the barge loading piers.[
The program also provides medical treatment for survivors who were present in the New York City Disaster Area in the aftermath of the 9/11 terrorist attacks because of work, residence, or attendance at school, child care, or adult day care.] Survivors also include individuals who happened to be present in this area on 9/11. The New York City Disaster Area includes the area of Manhattan south of Houston Street, as well as any block of Brooklyn either wholly or partially contained within a 1.5-mile radius of the former World Trade Center site. The program recognized the musicians, including Marya Columbia, who played for rescuers in lower Manhattan as eligible as well.
Conditions covered by the WTC Health Program
The WTC Health Program only provides tests and treatment for conditions specified by law in the Zadroga Act or certified by the WTC Program Administrator, who is the Director of the National Institute for Occupational Safety and Health. These include respiratory and digestive disorders and mental health conditions, as well as secondary conditions related to disease progression or complication from treatment of the primary covered health condition. Additionally, certain musculoskeletal disorders are covered for Fire Department of New York

members and other responders injured in the response to the terrorist attacks. As of June 2019, the 10 most common conditions certified by the World Trade Center Health Program were chronic rhinosinusitis, gastroesophageal reflux disease (GERD), asthma, sleep apnea, cancer, posttraumatic stress disorder (PTSD), chronic respiratory disease, chronic obstructive pulmonary disease (COPD), depression, and anxiety disorders. The most common cancers were skin cancer and prostate cancer.
Cancers and possible additions
The Zadroga Act established a process whereby the Administrator of the WTC Health Program may consider petitions by interested parties to add new conditions to the list of those covered by the WTC Health Program. In June 2012, Administrator Dr. John Howard proposed adding certain types of cancer

as recommended by the WTC Health Program Scientific/Technical Advisory Committee, in a Notice of Proposed Rulemaking. Many types of cancer were officially added to the coverage list in 2012–2014.
