Nasopharyngeal Carcinoma (NPC) DNA Screening
「Nasopharyngeal Carcinoma (NPC) is a type of head and neck cancer and it is one of the top ten cancer killers in Hong Kong. It has a particularly high incidence in Southeast Asia, especially in Guangdong and Guangxi in Mainland China and in Hong Kong, it’s known as the “Cantonese Cancer”.
Symptoms: nosebleed, headache and ringing in the ears
Many patients do not have any signs or symptoms until NPC reaches an advanced stage. Historical data shows that approximately 80% of unscreened patients are diagnosed with advanced NPC. Late-stage NPC is more difficult to treat than early-stage NPC and the survival rate within 5 years could be less than 60%.
Currently, there is no vaccination for the prevention of NPC as a type of virus-associated cancer. Early cancer screening is the one of the ways to secure a significantly better prognosis as it can help identifying asymptomatic NPC at a significantly earlier stage, which allows early interventions and treatments that greatly increase the chance of successful treatment and better prognosis.
