The patient has stable angina, which is controlled with medications including atorvastatin, metoprolol, and aspirin. His vital signs are within normal limits. BMI is 32 kgm2. Clinical examination reveals a 10 x 10-cm palpable mass in the left flank. Testicular examination indicates left varicocele. Laboratory parameters are as follows:UrineBlood 3WBC noneRBC 65hpf without dysmorphic featuresAbdominal CT scan confirms the presence of a large solid mass originating in the left kidney with impingement on the left renal vein. Based on the most likely diagnosis, which of the following is considered a risk factor in this patient?? A: Atorvastatin, B: Caucasian race, C: Lynch syndrome, D: Obesity, E: Varicocele,  <response>: Based on the description, this patient likely has renal cell carcinoma RCC originating in the left kidney. The key findings supporting this diagnosis are the left flank mass originating in the kidney, hematuria, and left varicocele caused by impingement of the tumor on the left renal vein. The question asks about a risk factor for RCC in this patient. Obesity is a known risk factor for RCC, with higher BMI associated with increased risk. The other options do not represent established risk factors. Atorvastatin and other statins have not been clearly linked to increased RCC risk. Caucasian race and varicocele are associated with RCC but are not considered risk factors for development of RCC. Lynch syndrome confers increased risk of certain cancers but not specifically RCC.D: Obesity
