Salivary gland cancer is a rare type of cancer that begins in the salivary glands. Diagnosing salivary gland cancer involves several steps, including a medical history review, physical examination, imaging tests, biopsy, and possibly additional specialized tests. Here’s an overview of the typical diagnostic process:
- Medical History and Physical Examination
- Medical History: The doctor will ask about symptoms, any risk factors, and family history of cancer.
- Physical Examination: The doctor will check for lumps or swelling in the jaw, neck, and mouth.
- Imaging Tests
- Ultrasound: Often the first imaging test used to examine salivary glands.
- Magnetic Resonance Imaging (MRI): Provides detailed images of soft tissues.
- Computed Tomography (CT) Scan: Offers detailed cross-sectional images and helps in assessing the spread of cancer.
- Positron Emission Tomography (PET) Scan: Sometimes used to find cancer that has spread to other parts of the body.
- Biopsy
- Fine Needle Aspiration (FNA) Biopsy: A thin needle is used to remove a small sample of tissue for examination.
- Core Needle Biopsy: A larger needle is used to remove a core of tissue.
- Surgical Biopsy: In some cases, a more extensive surgical procedure may be required to obtain a tissue sample.
- Pathology Examination: A pathologist examines the biopsy sample under a microscope to determine whether cancer cells are present and identify the type of cancer.
- Additional Tests
- Immunohistochemistry: Special stains are used to detect specific proteins in the cancer cells, helping to identify the cancer type.
- Molecular Testing: Tests to identify specific genes, proteins, and other factors unique to the tumor.
Diagnosis is a multi-step process involving various GW Cancer Center head and neck cancer specialists, including otolaryngologists, head and neck surgeons, plastic surgeons, medical and surgical dermatologists, medical oncologists, radiation oncologists, and speech pathologists, to ensure accurate identification and appropriate, personalized treatment planning. Regular follow-up and monitoring by your GW Cancer Center multidisciplinary team are essential to assess the treatment's effectiveness and manage any side effects or complications.
