What is Hnscc cancer?

Head and neck squamous cell carcinomas (HNSCC) are a heterogeneous group of malignant tumours typically caused by alcohol and tobacco consumption, although an increasing number of HNSCC arise due to persistent infection with high-risk human papilloma virus (HPV).

Is Hnscc curable?

HNSCC can spread (metastasize ) to other parts of the body, such as the lymph nodes or lungs. If it spreads, the cancer has a worse prognosis and can be fatal. About half of affected individuals survive more than five years after diagnosis.

Is lingual tonsil cancer curable?

Statistically, tonsil cancer isn’t likely to be fatal. As with most cancers, treatment is most successful when the condition is detected and treated in the early stages. Tonsil cancer that’s related to HPV has an overall survival rate of 85% to 90%.

How is HNSCC diagnosed?

PET Imaging. 18F-fluorodeoxyglucose PET (FDG-PET) is widely used as a diagnostic tool in HNSCC both for defining stage and evaluating treatment response.

How long can you live with metastatic squamous cell carcinoma?

The prognosis of patients with recurrent or metastatic head and neck squamous cell cancer is generally poor. The median survival in most series is 6 to 15 months depending on patient- and disease-related factors.

How long can you live with Stage 4 squamous cell carcinoma?

For a patient with stage IV cancer, age must also be considered to prognose survival. For a patient who is 67 years or older, the expected median survival is a little more than 1 year. If this patient were younger than 67 years, then the expected median survival would be about 2 years.

Is squamous cell carcinoma in the throat curable?

More than 90% of tumours in the head and neck are squamous carcinomas. Cancer of the head and neck, which can arise in several places, is often preventable, and if diagnosed early is usually curable.

Why are my lingual tonsils swollen?

The most common cause of lingual tonsillar enlargement is compensatory enlargement following tonsillectomy. Other potential causes include lymphoma, chronic infection and HIV. Irritation such as from smoking and gastro‚Äźoesophageal reflux disease (GORD) can also cause lingual tonsil hypertrophy.

What is tonsil cancer of the tonsils?

Tonsil cancer is an abnormal growth of cells that forms in a tonsil. Your tonsils are two oval-shaped pads in the back of your mouth that are part of your body’s germ-fighting immune system. Tonsil cancer can cause difficulty swallowing and a sensation that something is caught in your throat.

What happens when tonsil cancer spreads to lymph nodes?

When tonsil cancer spreads to the lymph nodes, it can travel from there to other parts of your body. Cancer that spreads to lymph nodes in your neck or to other organs has a worse prognosis than cancer that is only in your throat. This doesn’t mean your cancer can’t be treated — only that it may be harder to treat than an early-stage cancer. 1

How is chemotherapy used to treat tonsil cancer?

Chemotherapy uses drugs to kill cancer cells. For tonsil cancer, chemotherapy is usually combined with radiation therapy. It can also be used alone to slow the growth of tonsil cancer that has recurred or has spread to other areas of the body.

What are the key points of tonsil cancer?

Key points. Cancer of the tonsils usually involves the palatine tonsils on the sides of the throat. Men are diagnosed with tonsil cancer three to four times more often than women. People are generally diagnosed at age 50 or older but it can develop at any age.
