Common Symptoms of Throat Cancer

Depending on the location and stage of the cancer, there can be a variety of symptoms associated with throat cancer. It’s crucial to be aware of these symptoms and to get help if they continue. Common symptoms of throat cancer include:

Persistent Sore Throat:

A chronic sore throat that does not improve with time or treatment can be an early indication of throat cancer. If a sore throat persists for more than two weeks without apparent cause, it is recommended to consult a healthcare professional.

Difficulty Swallowing or Changes in Voice:

Throat cancer can cause difficulty in swallowing or a sensation of a lump in the throat. Changes in voice, such as persistent hoarseness or a raspy voice, can also be symptoms of throat cancer.

Hoarseness or Voice Changes:

Throat cancer can affect the vocal cords, resulting in hoarseness or changes in voice quality. If the voice does not return to normal within a few weeks, it is important to get it evaluated by a healthcare professional.

Ear Pain:

Throat cancer can cause referred pain in the ears. If you experience persistent or unexplained ear pain, especially in conjunction with other symptoms, it is advisable to seek medical attention.

Unexplained Weight Loss:

Significant and unintentional weight loss can indicate underlying health conditions, including throat cancer.

Swollen Lymph Nodes:

Throat cancer can cause the lymph nodes in the neck to become enlarged and tender. It is crucial to see a doctor to get your neck’s lymph nodes examined if you experience recurrent swelling or soreness there.

Chronic Cough:

A persistent and unexplained cough that lasts for an extended period, especially if accompanied by blood-tinged sputum, can be a sign of throat cancer. If a chronic cough continues, it is imperative to see a doctor.

Screening and Diagnosis                                             

To diagnose throat cancer, healthcare professionals employ various screening and diagnostic methods. These may include:

Physical Examination and Medical History:

A thorough examination of the throat, neck, and oral cavity is conducted to assess any abnormalities or signs of cancer. The patient’s medical history, including risk factors and symptoms, is crucial for accurate diagnosis.

B. Imaging Tests:

The throat, nearby structures, and potential cancer spread can all be seen through imaging examinations. Examples include positron emission tomography (PET) scans, computed tomography (CT), and magnetic resonance imaging (MRI).

C. Biopsy and Tissue Analysis:

Using a microscope, a sample of suspect tissue is examined after being removed during a biopsy to see if it is malignant.  Various biopsy techniques, including endoscopic, fine-needle aspiration, or surgical biopsy, can be used.

Staging of Throat Cancer:

Staging is done after a throat cancer diagnosis to identify the tumour’s degree and spread. Staging helps guide treatment decisions and prognosis. Staging may involve further imaging tests, such as chest X-rays, to assess potential metastasis.

Treatment Options

The treatment approach for throat cancer depends on several factors, including the cancer stage, the patient’s overall health, and personal preferences. Treatment options may include:

Surgery:

Surgical procedures are used to remove cancerous tissue and may involve removing a portion or all of the affected structures. For example, a laryngectomy involves the removal of the voice box, while a laryngectomy involves the removal of the pharynx.

Radiation Therapy:

Radiation therapy employs high-energy beams to eradicate cancer cells and shrink tumours. Radiation therapy employs high-energy beams to eradicate cancer cells and shrink tumours.  External beam radiation is delivered outside the body, while brachytherapy involves placing radioactive sources directly into the tumour. Radiation therapy may be used alone or in combination with other treatments.

Chemotherapy:

Chemotherapy utilizes drugs to kill cancer cells or prevent their growth. Cancer cells can be reached via systemic chemotherapy, administered through the bloodstream. Targeted therapy specifically targets cancer cells and their molecular characteristics.

Immunotherapy:

Immunotherapy aims to boost the body’s immune system to recognize and destroy cancer cells. Checkpoint inhibitors block proteins that prevent immune cells from attacking cancer cells. Adoptive cell therapy involves modifying immune cells outside the body and reintroducing them to target cancer cells.

Palliative Care and Supportive Treatments:

Throat cancer patients who receive palliative care have their symptoms managed, their quality of life enhanced, and their physical, emotional, and psychological needs met. Supportive treatments may include pain management, nutritional support, speech therapy, and counselling services.
