LARYNGEAL CANCERS Meaning and
Definition
-
Laryngeal cancer refers to the malignant growth or development of abnormal cells in the tissues of the larynx, also known as the voice box. The larynx is a vital organ located in the neck that plays a crucial role in producing sound for speech and assisting in the passage of air to and from the lungs during breathing. Laryngeal cancers can occur in any part of the larynx, including the glottis (vocal cords), subglottis (area just below the vocal cords), or supraglottis (above the vocal cords).
Laryngeal cancers are typically categorized into two main types: squamous cell carcinoma and adenocarcinoma. Squamous cell carcinoma is the most common type, accounting for about 95% of all laryngeal cancer cases. It originates from the flat cells lining the inner surface of the larynx. Adenocarcinoma, on the other hand, is a less common form that arises from glandular cells in the larynx.
Common symptoms of laryngeal cancer include hoarseness or voice changes, persistent sore throat, difficulty swallowing, ear pain, and a lump or swelling in the neck. While the exact causes of laryngeal cancer are not fully understood, risk factors such as smoking, excessive alcohol consumption, exposure to certain chemicals or substances, age, gender (men are more prone), and certain viral infections like human papillomavirus (HPV) have been identified.
Treatment for laryngeal cancer can include surgery, radiation therapy, chemotherapy, or a combination of these modalities, depending on the stage and location of the cancer. Early detection and prompt treatment are crucial for a more favorable prognosis and improved survival rates.

Etymology of LARYNGEAL CANCERS
The word "laryngeal" derives from the Greek word "larugx" meaning "the larynx" or "the throat". The term "cancer" comes from the Latin word "cancer" which originally referred to a crab, and it later came to be used metaphorically to describe a malignancy due to the crab-like appearance of the tumor, with its vessel extensions resembling the legs of a crab. Therefore, "laryngeal cancers" refers to malignancies that develop in the larynx or the voice box.
