Arizona residents may be interested in how some physicians have become more hesitant to screen smokers for lung cancer. A study published in 2011 revealed that spiral CT scans may have the ability to help lower the rate of lung cancer fatalities by 20 percent. As of February 2015, smokers aged 55 to 77 who averaged a pack a day for at least three decades may be qualified to receive an annual screening test for lung cancer, free of charge.
Patients in Arizona are usually diagnosed with cancer after a doctor takes a cell or tissue sample and looks at it under a microscope. The doctor may confirm that cancer is present by viewing the sample, or the diagnosis may be made after proteins, DNA and RNA in the sample are tested in a lab.
