One of the most dangerous malignancies is lung cancer. Better treatment is made possible by the early detection of this illness. This study's objective was to measure the serum levels of lead and cadmium (heavy metals) in healthy individuals (H.G.) of both sexes and compare those levels to those in individuals with non-healthy lung cancer (L.C.). 101 blood serum samples were gathered from the Middle Euphrates Cancer Center in the Iraqi province of Najaf, consisting of 54 males and 47 females. Using an FAAS, the levels of serum cadmium and lead were examined (flame atomic absorption spectrophotometer). The respective mean serum levels of lead and cadmium were 3.73538±0.067131μg/L and 8.92525± 0.02314μg/L for health men, 9.34477 ± 0.04122 μg/L and 6.08752±0.05112 μg/L for lung cancer men while 6.63905± 0.030212 μg/L and 20.94029± 0.2910 μg/L for health female, 8.75170±0.23401 μg/L and 12.93259± 0.6032 for lung cancer female , it is generally higher than the permissible limits ,which consequently increases the health risk of the exposed individuals.
