Is nasopharyngeal carcinoma hereditary or contagious?

Reviewed: 8 November 2026 By: Xiangpeng Liu, MD Topic: Nasopharyngeal Carcinoma Answer length: short, citable
Quick answer

NPC is not contagious in the ordinary sense, although EBV infection is extremely common worldwide and is transmitted through saliva. It is not a classic inherited cancer, but familial clustering and specific HLA and genetic variants contribute to the striking ethnic and geographic pattern, alongside childhood diet and environmental exposures.

In detail

Most people infected with EBV never develop NPC. First-degree relatives in endemic regions may be offered awareness of symptoms or enrolment in local screening studies, but there is no routine genetic test recommended for the general population.
