Thyroid cancer. Thyroid cancer is the most common cancer of the head and neck region and affects three times more women than men. Differentiated carcinomas are the most frequent types. Among them are papillary (between 50% and 80% of cases), follicular (from 15% to 20% of cases) and Hürthle cells. There are also poorly differentiated carcinomas (about 10% of cases) and undifferentiated carcinomas (also about 10%).

Laryngeal cancer. The larynx is the part of the throat that contains the vocal cords and participates in speech, but it has other important functions such as breathing and protecting the lungs from aspiration of food during swallowing. It is divided into subglottis, glottis and supraglottis. The vocal cords are located in the glottis, small folds that vibrate with the passage of air and are part of the vocal apparatus. Malignant tumors can arise in any region of the larynx, but 60% of them develop in the glottis. The most common type is squamous cell carcinoma.

Mouth cancer. Cancer of the mouth (also known as cancer of the lip and oral cavity) is a malignant tumor that affects the lips, mouth structures such as the gums, cheeks, roof of the mouth, tongue (especially the edges) and the area under the tongue.

Esophageal cancer. The esophagus is a hollow muscular tube, located between the trachea and the spine and that connects the throat to the stomach, where tumors can grow. The main symptom of esophageal cancer is difficulty swallowing. In the initial phase, this difficulty happens with solid foods. Then with the pasty ones and, finally, with the liquids. Therefore, most people with the disease lose weight and experience anemia and dehydration.
