Throat cancer is a group of cancers that can develop in different parts of the throat, including the pharynx and larynx.

These cancers can affect the tissues involved in breathing, swallowing, and speaking.

At Bay Biosciences, we provide high-quality Throat Cancer Samples and other Oncology Biospecimens for research, biomarker discovery, diagnostics, and drug development purposes.

Understanding Throat Cancer

Throat cancer can develop in the pharynx, larynx, tonsils, vocal cords, and other tissues within the throat.

Healthcare professionals generally refer to these cancers according to their specific location rather than using the broad term “throat cancer.”

Researchers study Throat Cancer Samples to investigate cancer biology, disease progression, biomarkers, and potential therapeutic targets.

The two main types of throat cancer include pharyngeal cancer and laryngeal cancer.

Throat Cancer Samples for Research

Pharyngeal Cancer

Pharyngeal cancer develops in the pharynx, the hollow tube located behind the nose and mouth.

It can be divided into:

  • Nasopharyngeal cancer: develops in the upper part of the throat.
  • Oropharyngeal cancer: develops in the middle part of the throat.
  • Hypopharyngeal cancer: develops in the lower part of the throat.

Pharyngeal Cancer Samples can help researchers investigate the biological characteristics of these cancers and identify potential biomarkers for diagnosis and treatment.

Laryngeal Cancer

Laryngeal cancer develops in the larynx, also called the voice box. It can affect different regions, including the supraglottis, glottis, and subglottis.

Researchers may use Human Tumor Tissue Samples from laryngeal cancer patients to study tumor characteristics, molecular changes, and treatment response.

Signs and Symptoms of Throat Cancer

Throat cancer symptoms can vary depending on the location and stage of the disease.

Common symptoms may include:

However, these symptoms can also occur because of other health conditions. Persistent or unusual symptoms should therefore be evaluated by a healthcare professional.

Causes and Risk Factors of Throat Cancer

Several factors can increase the risk of developing throat cancer.

Smoking and Alcohol

Smoking and other forms of tobacco use are important risk factors for throat and laryngeal cancers. Similarly, heavy alcohol consumption can increase the risk of certain throat cancers. Using tobacco and alcohol together can further increase this risk.

Human Papillomavirus

Certain types of human papillomavirus (HPV) are associated with some oropharyngeal cancers. HPV infection can cause changes in cells that may contribute to cancer development.

Other Risk Factors

Other factors associated with throat cancer include older age, exposure to asbestos, poor oral hygiene, a diet low in fruits and vegetables, high body weight, and certain inherited genetic conditions.

Researchers continue to investigate how environmental, genetic, infectious, and lifestyle factors contribute to throat cancer development.

Prevention of Throat Cancer

Not all cases of throat cancer can be prevented.

However, several measures may help reduce the risk.

These include:

  • Avoiding tobacco products
  • Quitting smoking
  • Limiting alcohol consumption
  • Maintaining a healthy body weight
  • Eating a balanced diet rich in fruits and vegetables
  • Maintaining good oral hygiene
  • Taking steps to reduce the risk of HPV infection

Diagnosis of Throat Cancer

Healthcare professionals use several methods to diagnose throat cancer. The diagnostic process usually begins with a review of symptoms and medical history, followed by a physical examination.

Laryngoscopy

A laryngoscopy allows a healthcare professional to examine the throat and larynx. An endoscope may be used to obtain a closer view of the tissues.

Biopsy

If an abnormal area is identified, a biopsy may be performed. During a biopsy, a tissue sample is removed and examined under a microscope to determine whether cancer cells are present. These tissue specimens can provide important information about the type and characteristics of the cancer. 

Imaging Studies

Doctors may also use imaging tests to evaluate the location and extent of cancer. These may include:

A barium swallow may also be used to examine the esophagus when needed.

Staging of Throat Cancer

After confirming a diagnosis, healthcare professionals determine the stage of the cancer. Staging describes the size and extent of the tumor and whether cancer has spread to nearby lymph nodes or distant organs.

The TNM system considers:

  • T: the size and extent of the primary tumor
  • N: involvement of nearby lymph nodes
  • M: spread of cancer to distant parts of the body

The cancer stage, tumor characteristics, and other patient-specific factors help healthcare professionals determine an appropriate treatment plan.

Treatment of Throat Cancer

Treatment depends on the type, location, and stage of throat cancer. Doctors may use one treatment or combine several approaches.

Common treatment options include:

Surgery

Surgery may be used to remove localized tumors. Depending on the location and extent of the cancer, procedures may include endoscopic surgery, cordectomy, laryngectomy, pharyngectomy, or neck dissection.

Radiation Therapy

Radiation therapy uses high-energy radiation to destroy cancer cells. It may be used after surgery or as part of the primary treatment for certain throat cancers.

Chemotherapy

Chemotherapy uses medicines that destroy cancer cells or slow their growth. Doctors may use chemotherapy alone or together with radiation therapy for some advanced cancers.

Targeted Therapy

Targeted therapies act on specific molecules or pathways involved in cancer growth. Researchers continue to investigate targeted treatments for different types of throat cancer.

Immunotherapy

Immunotherapy helps the immune system recognize and attack cancer cells. Certain immune checkpoint inhibitors may be used for some advanced throat cancers.

Applications of Throat Cancer Samples

Researchers use Throat Cancer Samples in several areas of cancer research.

Cancer Biomarker Research

Human Tumor Tissue Samples can help researchers investigate molecular and cellular changes associated with throat cancer. These studies may support the identification and validation of potential biomarkers.

Oncology Research

Human Cancer Tissue Samples allow researchers to study tumor biology, disease progression, and differences between cancer subtypes.

Drug Discovery and Development

Oncology Biospecimens can support pharmaceutical research by helping scientists investigate potential therapeutic targets and evaluate treatment responses.

Molecular and Histological Research

Fresh Frozen Tumor Tissue can be used for molecular research, while FFPE Tissue Samples provide an established format for histological and other laboratory studies.
