China is the high occurrence areas of esophageal cancer in the world.At present,the treatment for esophageal cancer patients is used to be the chemotherapy which makes patients to suffer a lot.If early detection and timely treatment is achieved,that means a higher chance of survival.In this paper spectrophotometer is used to check the serum spectra of esophageal cancer patients and healthy men.Samples are normally configured for each case at first and then tested with ultraviolet-visible absorption spectrum.Using Origin software for statistical analysis,it is found that:esophageal cancer patients′ serum have a much higher absorption value at 414 nm than the normal ones.And there exists obvious difference between the spectral ration characteristic of esophageal cancer patients and the normal people (I278/I253).Therefore,these serum absorption spectra data can be used in rapid and early diagnosis of esophageal cancer.
