Vocal cords have normal mobility. T2: Tumour invades mucosa. There is no fixation of the larynx. T3: Tumour causes fixation of the vocal cords, with or without invasion of neighbouring areas. T4: T4A – Tumour invades at least one of the following: the outer cortex of the thyroid cartilage, extra-laryngeal tissue
T1 or T2 or T3: the tumor's growth is between less than 2 cm and more than 4 cm and may be affecting the vocal cords. AND N1: cancer has spread to one lymph node (same side of the neck as tumor), which has swollen to 3 cm or less. OR T3: the tumor is more than 4 cm and is affecting the vocal cords. BUT there is no lymph node involvement. [3]
The Mayo Clinic Cancer Center is one of the oldest NCI-designated cancer centers in the United States, having first been designated in 1973. [3] The main location of the Mayo Clinic is in Rochester, MN. Campuses in Arizona and Florida opened later and became part of the Mayo Clinic Cancer Center in 2003. [4] [5]

Generally, there are three different types or treatment methods that can be used for patients with nasopharyngeal carcinoma. These three treatments are radiation therapy, chemotherapy, and surgery. Although there are currently three treatment methods, there are clinical trials taking place that may develop more effective treatments for NPC.

[3] [4] Synonyms have included cylindroma, ceruminoma, ceruminous adenocarcinoma, not otherwise specified (NOS), ceruminous adenoid cystic carcinoma (ACC), [1] [2] and ceruminous mucoepidermoid carcinoma.
Medical history, physical examination and medical imaging may suggest a squamous-cell carcinoma, but a biopsy for histopathology generally establishes the diagnosis. TP63 staining is the main histological marker for squamous-cell carcinoma. In addition, TP63 is an essential transcription factor to establish identity of the squamous cells. [18]
