Persistent Throat and Nasal Symptoms: When to Consider Cancer Screening - Otolaryngology

Nasal symptoms


Hello doctor, I have been experiencing persistent nasal discharge, a sensation of a foreign body in my throat, and difficulty coughing up phlegm for the past two months.
I often feel the need to clear my throat, and the phlegm has been blood-tinged.
Recently, my nasal discharge has improved, but the phlegm still contains blood.
I would like to know if I need to undergo any examinations, such as for nasopharyngeal cancer.
Thank you, doctor.

If there is blood in the sputum, it is recommended to visit an otolaryngologist or a pulmonologist for examination.

More Info


Persistent throat and nasal symptoms, especially when accompanied by blood-streaked phlegm, can indeed be concerning and warrant further investigation. While it is essential to remember that not all symptoms indicate cancer, certain persistent symptoms should prompt a discussion with your healthcare provider about the possibility of more serious conditions, including nasopharyngeal cancer.

Nasopharyngeal cancer (NPC) is a type of head and neck cancer that originates in the nasopharynx, the area behind the nose and above the back of the throat. Symptoms of NPC can be quite nonspecific and may overlap with those of other, more benign conditions. Common symptoms include:
1. Nasal Obstruction: Difficulty breathing through the nose or a feeling of congestion.

2. Nasal Bleeding: Frequent nosebleeds or blood-streaked nasal discharge.

3. Ear Symptoms: Hearing loss, tinnitus (ringing in the ears), or a feeling of fullness in the ear.

4. Throat Symptoms: A sensation of a lump in the throat, persistent sore throat, or difficulty swallowing.

5. Cervical Lymphadenopathy: Swelling of the lymph nodes in the neck, which may be painless.

6. Headaches: Persistent headaches that do not respond to typical pain relief methods.

In your case, the presence of persistent phlegm, especially if it is blood-streaked, along with a sensation of a foreign body in the throat, raises a red flag. While these symptoms can be caused by various conditions, including allergies, infections, or even benign growths, they can also be indicative of nasopharyngeal cancer, particularly given your description of the symptoms persisting over two months.

Given your symptoms, it would be prudent to consult an ear, nose, and throat (ENT) specialist. They may recommend several diagnostic tests, including:
1. Nasal Endoscopy: This procedure allows the doctor to visualize the nasal passages and nasopharynx directly, helping to identify any abnormalities.

2. Imaging Studies: A CT scan or MRI of the head and neck can provide detailed images of the nasopharynx and surrounding structures, helping to identify any masses or lymph node enlargement.

3. Biopsy: If any suspicious lesions are found during endoscopy or imaging, a biopsy may be performed to determine if cancerous cells are present.

It is essential to communicate all your symptoms clearly to your healthcare provider, including the duration and any changes in your symptoms. This information will help them assess your risk factors and decide on the appropriate course of action.

Additionally, considering your family history and any potential exposure to risk factors (such as certain viruses like Epstein-Barr virus, environmental toxins, or smoking), your doctor may take these into account when evaluating your symptoms.

In summary, while many conditions can cause the symptoms you are experiencing, the persistence of these symptoms, particularly the presence of blood in your phlegm, should not be ignored. Early detection is crucial in managing any potential malignancy effectively, so seeking medical advice promptly is the best course of action.
