Tonsil cancer is one of the malignant tumors of the tonsils. It accounts for most of them. It accounts for about 92-98%, most of which are sarcomas. Squamous cell carcinoma is the most common among tonsil carcinomas. It originates on the upper pole of tonsil and appears as a small grayish-white protrusion; some originate from the epithelium of tonsil crypt, which may have ulceration and infiltration, and may invade the tongue and palate arch and soft palate, pharyngeal and nasal tissues; it may metastasize to distant and near tissues. Lymphosarcoma is more common than lymphosarcoma. Initially, the lymphatic follicles increase in size, then break through the envelope and infiltrate the surrounding tissues, but the surface is smooth without ulceration, and the unilateral tonsils are obviously enlarged and develop faster, with early lymph node metastasis. Chinese medical evidence: 1. Qi, blood, phlegm and stagnation: the unsuitable emotion, anger and worries make the qi unfavorable and the transportation and transformation abnormal, resulting in stagnation of qi and blood, and the accumulation of phlegm and dampness; 2. Fire and poison trap the knot; the rotten flesh damages the veins, and the momentum is unstoppable, causing the cancer tumor to run away; 3. Evil trapped and decaying: cancer pain for a long time, hurting yin and consuming qi, losing essence and blood, causing deficiency of spleen and kidney, resulting in the great decay of qi. The cancer tumor will break down and be difficult to converge, which will eventually lead to death due to exhaustion of vital energy. Early diagnosis and early treatment are very important. In the early stage, the tumor may be small and asymptomatic. With the growth of the tumor, pharyngeal discomfort, pain, reflex ear pain, difficulty in swallowing, bloody sputum and bad breath, generalized malignancy, examination: one side of the tonsil is enlarged and hardened, congested, ulcerated, with pseudo-mold or bloody secretion on the surface, and some are cauliflower-like. There are enlarged lymph nodes in the middle of the neck and under the jaw. Cytologic smear examination and tissue biopsy can confirm the diagnosis. Imaging helps to understand the extent of the tumor. Treatment: Surgical treatment combined with radiation therapy. It can achieve better results. Prevention: 1. maintain a happy mood and achieve psychological balance; 2. pay attention to oral hygiene, quit smoking and abstain from drinking, eat less spicy, oily and hot food; avoid eating moldy and toxic food; 3. diagnose and treat early.
