Which statement made by a client undergoing an admission assessment indicates a risk factor for esophageal cancer?

The statement made by a client regarding smoking for 20 years indicates a significant risk factor for esophageal cancer. Smoking is well-documented in medical literature as a major contributor to the development of various cancers, including those of the esophagus. The carcinogenic compounds in tobacco smoke can lead to cellular mutations and abnormalities in the esophageal lining, thus increasing the likelihood of malignancy.

In contrast, the other statements reflect generally healthier lifestyle choices or factors that are less commonly associated with increased cancer risk. For instance, consuming plenty of fresh fruits and vegetables is typically associated with lower cancer risk due to the presence of essential vitamins, minerals, and antioxidants. The weight and height provided suggest a normal body mass index, which is not a risk factor, and the minimal alcohol consumption is also considered low-risk in terms of cancer development. Therefore, the long history of smoking stands out as a significant risk factor for esophageal cancer.
