How do medical experts view laryngeal tumors?

Laryngeal tumors can be said to be a rising star among malignant tumors, but their harm cannot be ignored just like other malignant tumors. So, how do medical experts view this very harmful laryngeal tumor?
Understanding of laryngeal tumors in histology <br/>Histologically, squamous cell carcinoma is the most common laryngeal tumor, accounting for about 95% to 98%. Adenocarcinoma is rare, accounting for about 2%. Undifferentiated carcinoma, lymphosarcoma, and fibrosarcoma are rare. Laryngeal squamous cell carcinoma can be divided into three types according to its development stage: carcinoma in situ, early invasive carcinoma, and invasive carcinoma. Carcinoma in situ is rare and can develop into invasive carcinoma after a period of time; early invasive carcinoma is generally caused by carcinoma in situ breaking through the epithelial basement membrane and infiltrating downward, and forming cancer nests in the lamina propria; the vast majority of laryngeal invasive carcinomas are well-differentiated squamous cell carcinomas, and cancer cells can be seen with different degrees of keratinization and intercellular bridges. Keratin beads can be seen in the center of the cancer nests. Poorly differentiated squamous cell carcinoma is rare.

Spindle cell carcinoma <br/>Sometimes the tumor is mainly composed of spindle cells, which is called spindle cell carcinoma. The cancer cells are arranged in a disordered manner and do not form cancer nests, which is quite similar to sarcoma. Verrucous carcinoma is a subtype of laryngeal invasive squamous cell carcinoma. It is rare, accounting for 1% to 2% of laryngeal tumors. The tumor grows in a warty manner into the laryngeal cavity, forming a cauliflower-like mass. Under the microscope, it is mostly papillary in structure and is a well-differentiated squamous cell carcinoma. Local infiltration of varying degrees can be seen, it grows slowly, and metastasis is rare.

Vocal cord cancer <br/>Vocal cord cancer is the most common laryngeal tumor, accounting for about 60% and is well differentiated; most are grade I and II, with less metastasis. The incidence of supraglottic cancer is about 30%, with poor differentiation of cancer cells and more common metastasis. Subglottic cancer is rare, accounting for about 6%. The tumor may appear as a papillary, warty or cauliflower-like protrusion when viewed with the naked eye, and may also form ulcers locally. Secondary laryngeal cancer is rare and is generally spread and infiltrated from the thyroid gland, laryngeal vesicle, and esophagus. Laryngeal tumors that metastasize from distant sites are rare and can be metastasized from skin melanoma, digestive tract adenocarcinoma, breast cancer, adrenal tumor, lung cancer, etc.
