“There is strong evidence that a fairly simple, five-minute low-dose, low-radiation scan can really save many lives,” said Dr. Bernard J, a lung surgeon and director of clinical screening at the Memorial Sloan Kettering Cancer Center in New York. He estimated that 75% to 85% of cancers detected by this examination are stage 1 and can be treated simply by surgery or radiation.
Dr. Park said many people who registered for the show quit smoking or tried to quit, but few saw clear screening as a sign that they could continue smoking.
Dr. Smith said the American Cancer Society should review its own guidelines for lung cancer screening so that its advice would likely be similar to that of a working group.
In 2013, the American Academy of Family Physicians refused to offer pros or cons of lung cancer CT screening, saying there was insufficient evidence. The president, Dr. Ada Stewart, said in an e-mail on Monday that the academy would review evidence of a new working group to decide whether to update its proposal to its members.
Worldwide, there were 2.09 million new cases of lung cancer in 2018, the “disease” being the leading cause of cancer deaths, according to which 1.76 million people died that year, according to the World Health Organization.
According to the National Cancer Institute, 228,820 new cases of lung cancer were registered in the United States in 2020, and 135,720 people died from it. About 90 percent of cases occur in smokers, and currently smokers are about 20 times more likely to develop the disease than non-smokers.
Only 20.5 percent of patients survive five years after diagnosis. Most cases are diagnosed late after the cancer has started to spread. But if it can be found ել cured early, cure is possible, doctors say.
