Nasopharyngeal carcinoma, chronic sinusitis?


Hello Dr.
Chi, I am currently working abroad, and it's not very convenient for me to see a doctor.
I have been experiencing post-nasal drip symptoms for a while.
A few months ago, I had acute sinusitis and was treated with antibiotics for three weeks, which cured it.
Since then, I have had mild unilateral nasal congestion upon waking, but it usually resolves quickly.
Recently, for several days, I have noticed that the clear mucus from my post-nasal drip has a slight pinkish tint, but it is not bright red—more of a faint pink.
The post-nasal drip does not occur all day; most of the time, it is clear or slightly yellowish, with occasional instances of the faint pink color in the morning.
I have checked my neck and found no swelling or lumps, but I am still concerned whether this could be a precursor to nasopharyngeal cancer.
I would appreciate your assistance in clarifying this matter.
Thank you.

Hello, there are many causes of nosebleeds, the most common being thin nasal mucosa, which can occur from forceful nose blowing.
However, conditions such as nasopharyngeal or nasal cavity tumors (like nasopharyngeal carcinoma), sinusitis, fungal infections, allergic rhinitis, hypertension, coagulopathy, and nasal trauma can also lead to nosebleeds.
The three common symptoms of nasopharyngeal carcinoma are nosebleeds, neck masses, and ear fullness; however, not all patients with nasopharyngeal carcinoma will exhibit these symptoms.
It is advisable to consult an otolaryngologist for an endoscopy.
Wishing you peace and health.
Sincerely, Dr.
Chi Chao-Yun, Head of the Department of Otolaryngology, Taichung Hospital, Ministry of Health and Welfare.

When it comes to distinguishing between chronic sinusitis and nasopharyngeal cancer, it is essential to understand the symptoms and the underlying conditions associated with each. Chronic sinusitis is a common condition characterized by inflammation of the sinuses, leading to symptoms such as nasal congestion, post-nasal drip, facial pain or pressure, and sometimes a reduced sense of smell. On the other hand, nasopharyngeal cancer, while less common, can present with symptoms that may overlap with those of chronic sinusitis, making it crucial to be vigilant about any changes in your health.

In your case, you have reported experiencing post-nasal drip, occasional blood-tinged mucus, and a history of acute sinusitis. The presence of blood in your mucus, especially if it is a new symptom, can understandably raise concerns about nasopharyngeal cancer. However, it is important to note that blood-tinged mucus can also occur due to irritation of the nasal passages, particularly in individuals with chronic sinusitis or allergies. Factors such as dry air, frequent nose blowing, or even the use of nasal sprays can contribute to this irritation.

The symptoms of nasopharyngeal cancer can include persistent nasal obstruction, unilateral (one-sided) nasal congestion, ear symptoms such as hearing loss or tinnitus (ringing in the ears), and sometimes neck lumps due to lymph node involvement. While you mentioned that you do not have any neck swelling, it is still essential to monitor your symptoms closely. The fact that you have a history of chronic sinusitis and have recently experienced a mild, transient nasal obstruction suggests that your symptoms may be related to your chronic condition rather than cancer.

Given your concerns, it is advisable to seek a thorough evaluation by an ear, nose, and throat (ENT) specialist. They can perform a nasal endoscopy to visualize the nasal passages and nasopharynx directly. This examination can help rule out any suspicious lesions or tumors. Additionally, imaging studies such as a CT scan may be recommended if there are any findings that warrant further investigation.

It is also worth considering other factors that could be contributing to your symptoms. For example, allergies can lead to chronic nasal congestion and post-nasal drip, which may explain some of your symptoms. If you have not already done so, discussing allergy testing with your healthcare provider may be beneficial.

In summary, while your symptoms warrant attention, they do not definitively indicate nasopharyngeal cancer. The best course of action is to consult with an ENT specialist who can provide a comprehensive evaluation and appropriate diagnostic tests. Early detection and diagnosis are key to managing any potential health issues effectively. Remember to keep track of any changes in your symptoms and communicate them to your healthcare provider, as this information can be crucial in guiding your diagnosis and treatment.

If you are concerned about nasopharyngeal cancer, you can undergo an endoscopic examination. If a nasopharyngeal mass is confirmed, further biopsy of the mass should be performed at the hospital for testing. Wishing you peace and good health.
