How long does laryngeal cancer have symptom is what?
summary
Although our current medical level has been able to achieve effective control in the early stage of laryngeal cancer, many people still talk about cancer discoloration. It can be seen that the harm of laryngeal cancer is very strong. If we want to find the disease in the early stage, we must have a certain understanding of laryngeal cancer. How long does laryngeal cancer have symptom is what? Let's talk about it
How long does laryngeal cancer have symptom is what?
Because the primary site is the vocal cord, the early symptoms are voice changes, such as voice fatigue, weakness, easy to be considered as "pharyngitis", so over 40 years old, hoarseness more than 2 weeks, should be carefully examined by laryngoscope.
With the development of the tumor, hoarseness may aggravate or even lose voice, and the increase of tumor volume may cause dyspnea. In the late stage, with the development of the tumor to the supraglottic or infraglottic region, it may be accompanied by radiation otodynia, dyspnea, dysphagia, expectoration and halitosis.
Finally, they may die of massive hemorrhage, aspiration pneumonia or cachexia. In general, this type is not easy to metastasize, but when the tumor breaks through the glottic area, lymph node metastasis occurs quickly. The primary laryngeal carcinoma is located in the laryngeal ventricle, across the supraglottic region and glottic region. It takes more than six months from the first symptom to the definite diagnosis.
matters needing attention
In histology and embryology, the left and right sides of the larynx develop independently. Supraglottic, glottic and subglottic primordia are derived from different primordia; The left and right lymphatic drainage are not connected with each other, and the supraglottic, glottic and subglottic lymphatic drainage are independent, which provides the basis for laryngeal surgery, especially partial laryngectomy. According to the location of the cancer, different surgical methods can be used.
