Tonsil cancer, a type of head and neck cancer, has become a rising concern in recent years. Head and neck cancers encompass a wide range of malignancies affecting areas such as the tongue, tonsils, and throat, including parts like the larynx or voice box. Rare cancers of the salivary glands, sinuses, and nose also fall under this category.
The tonsils, located on both sides of the back of the throat, play a key role in the body’s immune system. These almond-shaped tissues are part of the lymphatic system, and their primary function is to fight infections. Tonsils are made up of lymphoid tissue, which explains their lumpy appearance. Similar lymphoid tissue is also found on the surface of the back of the tongue.
Understanding Tonsil Cancer
Cancers that originate in the tonsils or the back of the tongue are classified as oropharyngeal cancers, and a significant majority (around 70%) of these cases are linked to the human papillomavirus (HPV). HPV-related head and neck cancers are more commonly diagnosed in men, and the most frequent sign of this type of cancer is the discovery of a lump in the neck. Patients often describe it as “I was shaving and felt a lump in my neck.” In many cases, however, there are few other symptoms, although some individuals may experience discomfort when swallowing or a sensation of something being stuck in their throat.
HPV is a virus that most people will be exposed to at some point in their lives. The primary mode of transmission is sexual contact, and many individuals are exposed to the virus in their teens or early twenties. In most cases, HPV does not cause symptoms, and the immune system clears the virus naturally. However, in approximately 10% of people, the virus becomes chronic, increasing the risk of cancer development years or even decades later.
Treatment and Prognosis
One promising aspect of HPV-related cancers is that they often respond well to treatment, with a higher cure rate compared to non-HPV-related cancers, which are typically associated with smoking and alcohol consumption. When diagnosed with head and neck cancer, doctors conduct extensive testing to assess whether the cancer has spread to nearby lymph nodes or other parts of the body. This information is crucial for determining the appropriate treatment plan.
For localized cancers, treatment often includes a combination of surgery, radiation, or chemotherapy. If the cancer has metastasized to other organs, treatments typically involve chemotherapy and immunotherapy, delivered through the bloodstream to target the cancer systemically.
In 2016, the FDA approved immunotherapy for the treatment of advanced head and neck cancer. Ongoing research into next-generation immunotherapies and therapeutic vaccines, which aim to stimulate the immune system to fight cancer, shows promise for the future.
Prevention: A Better Approach
While treatment for head and neck cancer has become more effective, prevention remains the best strategy. Cancer treatments often come with long-term side effects that can impact the patient’s quality of life. The HPV vaccine, which has been available since 2006 in the U.S., is a key tool in preventing HPV-related cancers, including tonsil cancer.
The vaccine is FDA-approved for both males and females aged 9 to 45, and studies show that vaccinating individuals before they become sexually active yields the best results. However, even those up to age 45 can still benefit from the vaccine in terms of cancer prevention.
In addition to HPV vaccination, there are other measures individuals can take to reduce their risk of head and neck cancers:
- Quit smoking or using tobacco products, and avoid starting.
- Limit alcohol consumption, or better yet, abstain entirely.
- Adopt healthy lifestyle habits, such as regular physical activity and a diet rich in fruits, vegetables, and plant-based foods.
By combining vaccination with these lifestyle changes, individuals can significantly reduce their risk of developing tonsil and other head and neck cancers, ensuring better health for the future.
