Due to its insidious onset and subtle early symptoms, many nasopharyngeal carcinoma patients present at advanced stages, missing the optimal treatment window.
Wu Yanqiao, Director of Otolaryngology at Hainan Cancer Hospital, explains that early self-assessment is possible for nasopharyngeal carcinoma. "Early detection and early treatment" remains the most effective approach.
How can one conduct a self-assessment for nasopharyngeal cancer risk? Let Dr. Wu Yanqiao explain.
Watch for these warning signs of nasopharyngeal cancer
"The progression of nasopharyngeal cancer follows discernible patterns. Paying attention to daily observations and conducting timely self-assessments can aid in early detection and risk prevention."Wu Yanqiao outlined the warning signs: 1. Frequent, unexplained nasal congestion or nosebleeds without trauma, colds, or dry weather. 2. Blood in nasal discharge or blood-tinged sputum when sucking back phlegm. 3. Hearing loss, ear fullness, or a diagnosis of otitis media with effusion. 4. Progressive swelling of neck lymph nodes.Individuals experiencing these symptoms should promptly seek screening at specialized medical institutions for early detection of nasopharyngeal carcinoma.
Dr. Wu Yanqiao specifically emphasized that nasopharyngeal carcinoma exhibits not only distinct regional prevalence but also familial clustering. Family members, particularly direct relatives, of individuals diagnosed with nasopharyngeal carcinoma are considered high-risk groups and should undergo annual screening.
Ms. Fu from Ledong, Hainan, lost her father to advanced nasopharyngeal carcinoma eight years ago. Over a year ago, at age 45, Ms. Fu noticed blood streaks in her nasal discharge. Assuming it was caused by "heatiness," she purchased Chinese herbal medicine from a pharmacy and took it intermittently for over a year. Not only did her condition fail to improve, but she recently developed hearing loss.
In October this year, sensing something was wrong, Ms. Fu went to the Provincial Cancer Hospital for examination. After nasal endoscopy and pathological testing, she was ultimately diagnosed with advanced nasopharyngeal carcinoma, having missed the optimal treatment window. Dr. Wu Yanqiao expressed regret: "In cases like Ms. Fu's, if early screening had been conducted, or if she had sought medical attention promptly upon noticing blood in her nasal discharge, the treatment outcome would have been entirely different."
Individuals over 40 are at higher risk for nasopharyngeal carcinoma. Experts recommend that those born or living long-term in high-incidence areas undergo annual specialized screening for this cancer.
Can nasopharyngeal carcinoma be prevented?
Nasopharyngeal carcinoma is preventable and controllable. Scientific investigations indicate two key factors: First, diet plays a role. Individuals who regularly consume foods high in nitrosamines—such as salted fish, shrimp paste, pickled vegetables, and smoked meats—face a higher risk of developing the disease. Second, nasopharyngeal carcinoma has a "contagious" aspect.Nasopharyngeal carcinoma is closely linked to Epstein-Barr virus (EBV) infection. EBV, a member of the herpesvirus family, spreads through saliva and respiratory droplets via widespread transmission routes. Persistent positive infection may progress to nasopharyngeal carcinoma. Wu Yanqiao advises: First, cultivate healthy eating habits by minimizing or avoiding pickled foods. Second, maintain good personal hygiene by washing hands frequently and refraining from nose-picking.
Never Trust Folk Remedies
In September this year, Dr. Wu treated a young patient.
Eighteen-year-old Xiao Zhen was diagnosed with nasopharyngeal carcinoma at a local hospital due to swollen neck lymph nodes. Doctors recommended hospitalization.
However, her parents mistakenly believed in so-called folk remedies and attempted "leech therapy" at home to treat her.The result? Not only did the treatment fail, but it caused her neck lymph nodes to ulcerate, leading to septicemia infection and multiple organ failure—all while delaying proper medical care.Due to the narrow nasal cavity, endoscopic or CT scans are often necessary to detect subtle abnormalities. Therefore, upon experiencing symptoms, patients must seek diagnosis from specialists at reputable hospitals to avoid misdiagnosis or missed diagnoses that could cause harm."
Wu Yanqiao noted that with technological advancements, early-stage nasopharyngeal cancer treated via minimally invasive surgery achieves a three-year cure rate exceeding 90%. Thus, nasopharyngeal cancer need not be feared.
