Recently, the death of host Lee Wing has made everyone a little bit more aware of throat cancer, because according to reports online, Lee Wing passed away because of throat cancer.

Laryngeal cancer is a malignant tumor that occurs in the larynx and can be classified into supraglottic, glottic, and infraglottic types based on the relationship between the tumor and the vocal cords.

The exact cause of laryngeal cancer is not well understood and is mainly associated with the following:

First, smoking, the smoke contains a lot of carcinogens that can lead to cancer in the throat area.

Secondly, alcohol consumption, the risk of laryngeal cancer in alcohol drinkers is 1.5-4.4 times higher than that in non-alcohol drinkers, especially supraglottic laryngeal cancer is closely related to alcohol consumption.

Thirdly, air pollution, inhaling polluted air all day long can easily lead to throat cancer. Therefore, the incidence of laryngeal cancer is significantly higher in urban areas than in rural areas.

Fourth, human papillomavirus (HPV) infection, the HPV virus can cause laryngeal papillomas, which are now considered precancerous lesions of laryngeal cancer.

Fifth, androgens. Laryngeal cancer is most common in men, with a very low prevalence in women, suggesting that androgens play an important role in the development of laryngeal cancer.

Symptoms of Laryngeal Cancer

Early stage laryngeal cancer basically has no specific symptoms and it is difficult to distinguish it from chronic pharyngitis, such as nausea, foreign body sensation in the throat, itching sensation, swallowing discomfort and so on. With further development of the disease, more specific symptoms may appear, for example, theHoarseness, cough, blood in sputum, difficulty swallowing, radiating ear pain, swollen lymph nodes in the neck.

Men over the age of 40 who experience hoarseness for more than 2 weeks must go to the ENT department of a hospital and have a laryngoscopy to rule out the presence of laryngeal cancer. And for high-risk people who have been smoking and drinking for a long time, they should go to the hospital for a laryngoscopy once a year from the age of 40 for early detection of laryngeal cancer.

Hoarseness, pharyngeal foreign body sensation, sore throat, swallowing discomfortThese are early signs of laryngeal cancer, but they can also be easily confused with colds and pharyngitis, but it is not difficult to detect it if we pay more attention.

①Intractable hoarseness: Hoarseness due to colds and inflammation will improve quickly as the inflammation subsides, and theThe symptoms of hoarseness caused by laryngeal cancer will be progressively aggravated, and gradually develop into a thicker and muffled voice, until complete loss of voice... For patients over 40 years of age with hoarseness of voice for more than 1 month, it is recommended to visit the hospital for early screening.

②Abnormal throat sensation:Foreign body sensation, tightness or discomfort in swallowingThe symptoms can be easily mistaken for chronic pharyngitis. If you are over 40 years old and the above symptoms have been recurring for more than one month, you should consult a doctor in time for examination.

③Cough with blood in sputum: some small carcinomas can give the patient an irritating dry cough, and tumor breakage can lead to blood in sputum.You should pay special attention to the first sputum in the morning.. In addition, patients often have the feeling that their throat is stuck with mucus, so they will 'clear their throat' frequently. Blood in the sputum can be an early sign or an advanced symptom, so it is important to take it seriously once it is detected.

④Reflex earache and headache or sore throat sensation:Early laryngeal cancer combined with ulcers, inflammation, or laryngeal cartilage osteochondritis dissecans may present with reflex earache and headache or pharyngeal pain sensation。

Caution: The If symptoms such as a lump in the neck, difficulty in swallowing, or difficulty in breathing are present, the condition may have moved to the next stage and medical attention must be sought without further delay.People at high risk for laryngeal cancer who are over the age of 40 and prefer tobacco and alcohol should visit an ENT for an e-laryngoscopy at least once a year.

Laryngeal cancer mostly occurs in men aged 50-70, but due to more and more young people smoking, the incidence age of laryngeal cancer is now younger. The vast majority of laryngeal cancer patients have a long history of smoking and drinking.

The typical clinical manifestation of laryngeal cancer is hoarseness because the larynx is the organ for human body to pronounce words, when there is cancer here, it will affect the pronunciation of words, so there will be hoarseness. Vocal cord cancer can have hoarseness in early stage.

Laryngeal cancer will also have symptoms such as cough, bloody sputum, pain, throat discomfort, foreign body sensation, etc. However, these symptoms are non-specific, which means that many diseases will have the above mentioned symptoms, such as chronic pharyngitis, tonsillitis and so on.

Laryngeal cancer also manifests as choking cough, which is due to the fact that laryngeal cancer affects the cricoarytenoid joint movement. Once a middle-aged person has a choking cough, he should be alerted. Normal people will not have choking cough when eating, unless food falls into the airway accidentally. If the choking cough is recurrent, then these possibilities should be considered.

In the late stage of laryngeal cancer, there may be difficulty in breathing, which is due to the fact that the ventilation of the whole airway is affected. There will also be difficulty in swallowing, which is also caused by the invasion of the esophageal inlet by advanced laryngeal cancer.

(Ear Zhao Q&A 20181109) Laryngeal cancer is one of the head and neck tumors with high incidence rate, which can be ranked first in the northern region (nasopharyngeal cancer is more common in the southern region). Early symptoms of laryngeal cancer and the specific location of laryngeal cancer have a great relationship. If the tumor grows above the level of vocal folds in the early stage, and the patient's pronunciation is normal when the vocal folds are not involved, the symptoms caused by the tumor at this time are similar to those of chronic pharyngitis, which is easy to delay the diagnosis and treatment; if the tumor is in the area of the vocal folds, the hoarseness of the voice will appear at an early stage and the hoarseness of the voice will be present for a long period of time, and it will gradually aggravate; if the tumor If the tumor grows below the plane of the vocal folds, there may not be any symptom in the early stage until the tumor increases to a certain extent and involves the vocal folds or trachea, and then there will be obvious hoarseness and cough.

The test that can detect laryngeal cancer at an early stage is fiberoptic laryngoscope, which is similar to gastroscope, and enters the laryngeal cavity through the nasal cavity or oral cavity to clearly see the structures inside the larynx. This test should be done in cases of recurrent throat discomfort, hoarseness for more than two weeks, and unexplained cough.

At 5:20 a.m. on October 25, 2018, Li Yong, a famous host who once hosted "Super Speaker," "Lucky 52," and "Very 6+1," died after medical treatment for throat cancer, and his wife, Ha Wen, posted a condolence message on October 28: "Forever lost my love.

Early symptoms of laryngeal cancer are similar to pharyngitis and vocal cord inflammation, which are easy to cause misdiagnosis and at the same time not easy to attract patients' attention. Just like some teachers, actors, hosts and other people who use their voices more often think that they are just tired of their vocal cords and their voices are muffled, and they can rest for a few days, but in fact, this kind of people is more prone to delaying the diagnosis and treatment, which may lead to a tragedy.

Although laryngeal cancer is a kind of "niche" cancer, there are 40,000 victims in China every year. Moreover, the occurrence of laryngeal cancer is closely related to life habits, such as smoking and drinking, which are the causes of laryngeal cancer, therefore, prevention of laryngeal cancer should not be delayed.

Let's take a look at what are the early symptoms of laryngeal cancer?

hoarse

This is mainly due to the fact that laryngeal cancer occurs mainly on the vocal cords, so almost all patients will have hoarse voice. It should be noted that if the symptoms are not good for more than one month, you must go to the hospital for examination and diagnosis in time to exclude whether it is laryngeal cancer. If the voice is hoarse and does not get better for a long time, beware of vocal cord lesions and pay attention to them.

Neck mass

A long tumor in the larynx can produce a neck mass if metastasis occurs, and the location of the neck mass is usually in the part below the angle of the lower jaw. In the early stage, the mass can be pushed from side to side and is soft; in the late stage, the mass cannot be moved and is hard.

phlegm with blood in it

Due to the stimulation of the tumor can produce irritating dry cough with blood in sputum, and patients often have mucus sticking sensation. Tumor enlargement will also block the airway, so that tracheal secretions are not discharged smoothly, causing respiratory infection, wheezing and even dyspnea, and in the middle and late stages, it is manifested as persistent cough and change of pronunciation.

Our body is our own. If we suffer from cancer, not only do we suffer from it, it will also add to the financial burden of our family, so it is very necessary to make conscious efforts to prevent cancer. Although laryngeal cancer is also a kind of cancer, it can be cured by early and timely treatment. Moreover, after successful treatment, it is usually necessary to take care of preventing recurrence, and it does not affect the use of the throat.

Larynx is our vocal organ, which is related to human vocalization and speech. Early symptoms of laryngeal cancer are related to the growth site of the tumor, and the clinical manifestations of different types of laryngeal cancer may vary. However, most patients have progressive worsening hoarseness, which is a common early symptom in laryngeal cancer. However, hoarseness can be easily neglected because it can be caused by many kinds of diseases, such as vocal cord inflammation, vocal cord nodule and vocal cord polyp. Generally speaking, if hoarseness is caused by inflammation of vocal cords, the condition will slowly improve after treatment, while hoarseness caused by laryngeal cancer is generally aggravated with the growth of tumor. Therefore, if hoarseness does not get better after treatment, one should consult a doctor in time to rule out laryngeal cancer or precancerous lesions.

In addition, if the tumor is below the level of the vocal folds, i.e., below the vocal folds, patients may not have any symptoms in the early stage, or the symptoms are not obvious, and some patients may have a foreign body sensation in the larynx. If the tumor is above the plane of the vocal folds, i.e., above the vocal folds, patients may experience a foreign body sensation in the larynx, or pain when swallowing, or some may experience hoarseness. If the tumor is in the vocal folds, hoarseness is usually present in the early stages, and this symptom will gradually worsen as the tumor grows.

All these symptoms need to be paid attention to. Of course, very often these symptoms will be easily ignored or considered as the result of common cold, so early detection of laryngeal cancer requires us to be more vigilant. For recurrent pharyngeal discomfort, hoarseness, foreign body sensation in the throat, or persistent or aggravating symptoms, one should consult a doctor for examination in a timely manner, and, if necessary, fiberoptic laryngoscopy, laryngodynamicoscopy and other related examinations can be carried out under the direction of doctors. Laryngoscopy, laryngodynamicoscopy and other related examinations.

I'm Dr. Shadow. Throat cancer is relatively rare and many people may not know about this cancer. It is said that famous hosts died because of laryngeal cancer, and laryngeal cancer once became one of the diseases that people were concerned about. The most common symptom of laryngeal cancer is hoarseness. If hoarseness occurs, you should first go to ENT department to see if it is a problem of vocal cords, and you can go to laryngoscopy. If the lump is bigger, CT examination is needed.

laryngeal cancer

Laryngeal cancer is a malignant tumor located in the larynx and is classified into primary and secondary. Primary refers to those that originate in the larynx, while secondary is the metastasis of cancers from other parts of the body to the larynx. What we call laryngeal cancer generally refers to primary.

Primary laryngeal cancers are categorized as supraglottic, glottic, and infraglottic. The most prevalent one is the cancer of the vocal folds, which originates from the vocal cords. Vocal cords are the organs for articulation, so it will first manifest as hoarseness. Of course, there are different symptoms according to different parts of the body.

Laryngeal cancer may be associated with alcohol consumption, smoking, occupation, air pollution, heredity, and other cancer-causing factors.

What are the symptoms of laryngeal cancer?

1. Early on, there can be no symptoms

Laryngeal cancer that originates in the upper and lower vocal folds can be asymptomatic in the early stages. Because it does not cause functional changes and has no symptoms, people will not go for examination and it will not be detected. It can also have only slight or non-specific sensations, such as itchy throat, foreign body sensation, discomfort in swallowing, and so on. It is possible to mistake chronic laryngitis for chronic laryngitis, thus delaying the condition.

2. Hoarseness

Laryngeal cancer is most common in the vocal folds, so the most common symptom is hoarseness. If you experience hoarseness, the first department you visit is going to be the ENT department and a laryngoscopy is done to look at it. Laryngoscopy can detect early laryngeal cancer.

There are many diseases that cause hoarseness, such as common vocal cord nodule, vocal cord paralysis and so on. The enlargement of mediastinal lymph nodes caused by lung cancer compresses the recurrent laryngeal nerve, and hoarseness may also occur.

If >40 year old male, presents with hoarseness that lasts for more than two weeks, a laryngoscopy is recommended. If the laryngoscopy is fine, it's time to look for further causes.

3. Dyspnea

The larynx is ventilated, and it is through the laryngeal cavity that the air we inhale goes into the lungs. If there is a lump in the larynx, a small tumor, it may not block the laryngeal cavity and cause breathing difficulties, but as the tumor grows larger, it becomes difficult for air to get in, and breathing difficulties can occur.

4. Blood in sputum, hemoptysis

Bleeding on the surface of laryngeal cancer, along with sputum discharge, can also appear as blood in sputum and hemoptysis. It is easy to think that it is a disease of the lungs, thus ignoring the disease of the larynx.

5. Enlarged lymph nodes

Laryngeal cancer can present with lymph node metastasis, which manifests as multiple enlarged lymph nodes in the neck and can be palpated as a lump in the neck. All cancers of head and neck can be metastasized through lymph nodes, which can be manifested as palpable lumps in the neck, among which nasopharyngeal cancer metastasis is the most common.

Laryngeal cancer can be asymptomatic in the early stages, and if hoarseness develops, it is still advisable to get a laryngoscopy. It is difficult to find small lesions with CT. If laryngoscopy reveals a mass, or if a mass with external pressure is found, further CT scan + enhancement scan can be done to assess the extent of tumor invasion and to evaluate the chance of surgery. Although laryngeal cancer is relatively rare, it is also highly malignant.

The human throat is the necessary passage for eating and breathing, and therefore it is also the part that is most prone to illness. Laryngeal cancer is a relatively common malignant tumor, and it is rumored that the famous host Li Yong died of this disease.

Let's learn about the related knowledge, laryngeal cancer is a malignant tumor originated from epithelial tissue of laryngeal mucosa, and the most common laryngeal cancer is laryngeal squamous cell carcinoma. The most common laryngeal cancer is laryngeal squamous cell carcinoma. Its occurrence is related to smoking, alcoholism, long-term inhalation of harmful substances and papilloma virus infection. Generally speaking, laryngeal cancer firstly affects people's speech and voice. Early detection and early treatment can cure the disease.

Laryngeal cancer is a common malignant tumor of the larynx with the following main symptoms:

1. Hoarseness: at the early stage of the disease, hoarseness is intermittent and gradually aggravated with the development of the disease, and it is easy to be mistaken as the result of cold. However, hoarseness caused by laryngeal cancer cannot be relieved or even gradually aggravated with the treatment of containing drugs or conventional antibiotics, and if hoarseness lasts for more than 3 weeks, it needs to be suspected of the possibility of laryngeal cancer, and it is recommended that the patients go to the hospital in time for diagnosis and treatment;

2、Pharyngeal pain: persistent pain, no relief after medication, some patients may have neck mass if combined with lymph node metastasis;

3、Difficulty in breathing: aggravation of the condition can affect breathing, and there is obvious breathlessness after strenuous activities;

4、Difficulty in swallowing: often suggests a more serious condition;

It is also important to note that radiating pain is not necessarily the focal point of the disease (the throat). This was the case with an old leader beside me, whose initial symptoms were toothache and headache, and who also had acupuncture treatments, and who was eventually found to have cancer of the pharynx (partial to the base of the tongue area). We also summarized the old leader's lifestyle that may be related to the disease: 1, like to drink very hot tea water (small sips of boiling water after rinsing especially hot); 2, like to drink strong alcohol (high white); 3, like to smoke strong cigarettes (Marlboro). Therefore, lifestyle is very important in preventing diseases, and we hope that you will have a healthier lifestyle and stay away from diseases.

Laryngeal cancer is a malignant tumor that occurs in the larynx, which is located at the top of the trachea and is an important passageway for its occurrence, so what laryngeal cancer tends to affect is vocalization as well as breathing, and the formation of nodules or lumps can also affect swallowing.

The above figure is a CT image of laryngeal cancer, which shows localized uneven soft tissue thickening and uneven enhancement.

What are the clinical manifestations of laryngeal cancer?

(1) Hoarseness.The larynx has a laryngeal chamber, which is composed of thyroid cartilage, cricoid cartilage, arytenoid cartilage, and epiglottis cartilage, and the vocal cords are located in the middle of the chamber, and the relaxation and tightening of the muscles within the chamber can control the vocal cords to produce different sounds.

When there is a tumor in the larynx, it will affect the airflow, the opening and closing of the vocal folds and the movement of the vocal cords in different degrees according to the different parts of the tumor, so it will affect the voice, and at the same time in the early stage, it will appear that the pronunciation is easy to be tired and weak. This is also an early symptom of laryngeal cancer.

(2) Difficulty in breathing, discomfort.The larynx is located at the top of the trachea and airflow passes through it when breathing, so when a tumor grows in the larynx, if it squeezes into the airway, it will affect the passage of airflow and make the trachea narrow, which in turn affects breathing and produces the feeling of difficulty and discomfort in breathing.

(3) Pharyngeal choking sensation/The larynx is adjacent to the esophagus, so when a tumor develops in the larynx, it will squeeze the esophagus. Initially, it is a sensation of choking in the throat, and later on, with the growth of the tumor, it will be difficult to swallow, and it will be difficult to swallow food and water.

The above are some of the common manifestations of primary laryngeal cancer, and for secondary laryngeal cancer, it will also be accompanied by some symptoms and characteristics of primary cancer, which is relatively rare.

For those with a high suspicion of laryngeal cancer and those with a high incidence of the disease, try to avoid smoking and eating foods that are too hot.If you experience discomfort in the throat that worsens without relief, it is important to go to the ENT department of the hospital in time for a checkup.

Early manifestations of laryngeal cancer should be difficulty in swallowing, a foreign body sensation, and always a feeling of discomfort in the throat.
