What are the basic facts about lung cancer?

There are two types of lung cancer, one is small cell lung cancer and the other is non-small cell lung cancer; Small cell lung cancer (SCC) cancer cells grow rapidly and metastasize easily, accounting for about 10 to 15% of all lung cancer patients, and the prognosis is usually poor; Non-small cell lung cancer (NSCLC) grows more slowly and metastasizes more slowly, accounting for the majority of lung cancers. At present, the 5-year survival rate of lung cancer is about 15%, and because of this reason, lung cancer is often the first cause of cancer death in China in recent years.

Only 10% of lung cancer patients can use surgery to remove cancer cells, and the current operable patients (non-small cell lung cancer) are mainly stage 1, stage 2, and stage 3a, and the probability of metastasis after surgery is also common, and the survival rates at five years after surgery are 36%, less than 30% in the third period; For early-stage small cell lung cancer, if surgical resection combined with chemical **, the three-year survival rate can reach 65% in the absence of lymphatic metastasis, but if lymphatic metastasis is present, the three-year survival rate drops to 30 50%; However, in patients with small cell lung cancer, the cancer cells have metastasized outside the chest cavity by the time the diagnosis is confirmed, and surgery is not used**, but usually with chemical **combined radiation**, which is known to improve the survival rate of patients more than alone**.

The incidence and mortality rate of lung cancer in China is very high, so we have been analyzing why the incidence of lung cancer in China is so high, and we also use smoking plus six modernizations to summarize and describe the incidence of lung cancer in China, smoking is a major cause of lung cancer, there are thousands of chemicals in tobacco, hundreds of harmful substances, 69 clear carcinogens, and our second-hand smoke and third-hand smoke, so smoking is the main culprit of lung cancer.

The rate of peripheral lung cancer is related to the staging, and the long-term rate is higher for patients who undergo surgery. , the standard of surgery and post-surgery, the rate of patients is higher than that of patients. **The risk is mainly related to whether the patient's early surgery is achieved, and whether the standard postoperative adjuvant chemotherapy or corresponding adjuvant radiotherapy is given after surgery according to the patient's high-risk factors and stage.

For patients who are inoperable, after chemoradiotherapy, whether the chemotherapy regimen and radiotherapy dose are reasonable and standard directly affect the patient's post-treatment. Patients who are able to undergo surgery or chemoradiotherapy at an early stage must see a specialized oncology department.

As the "number one cancer killer in the world", the incidence and mortality rates of lung cancer account for the total number of people with cancer, respectively, and the data are from the 2018 Global Cancer Statistics Report.

In China, the incidence of lung cancer is increasing at an annual rate, and it is estimated that by 2025, the number of people dying from lung cancer alone in China will be close to 1 million per year.

I've got 7 health tips for you that might help.

1.Smoking cessation and screening

As we all know, smoking is a serious health hazard that puts you at risk of lung cancer. Smoking is attributed to 90% of lung cancer cases. Smoking also increases the risk of chronic lung disease.

For the sake of your own health and that of your family, please quit smoking as soon as possible. Quit smoking within a year and you'll see a significant improvement in your health. Remember to get screened after quitting smoking, because you never know if you're going to get lung cancer.

Even if you've been diagnosed with lung cancer, stopping smoking will make your condition better.

2.Avoid secondhand smoke

If you don't smoke, but there are always people around you who smoke, then it's also difficult for you to reduce your lung cancer risk. Studies have shown that secondhand smoke is just as harmful as smoking, and even if you don't put the cigarette in your mouth, you can still inhale the smoke and damage your lungs. Therefore, try to avoid people who smoke and avoid exposure to smoking.

3.Check your home radon levels

Radon is an odorless gas that is produced by the decay of natural uranium from the subsoil of the home. Radon is one of the leading causes of lung cancer in non-smokers, as it can be inhaled into the lungs in combination with oxygen, increasing the risk of lung cancer. Therefore, it is important to have your radon levels measured regularly at home and take appropriate measures.

4.Supplement - Carotene

Carotene is an important nutrient for smokers. This antioxidant pigment is found in brightly colored fruits or vegetables, such as carrots, goji berries, wild amaranth, broccoli, spinach, water spinach, sweet potato, mango, cantaloupe, apricots and melons. Studies have shown that carotene has a positive effect on reducing the occurrence of lung cancer.

5.Eat more apples and oranges

Studies have shown that eating 5 or more apples per week can improve lung function. Studies have found that people who eat apples have better lung function than those who don't. At the same time, apples can also slow down the decline in lung function due to aging.

Regular consumption of red onions, oranges, etc. will also have the same effect, which can help improve lung function and reduce the risk of lung cancer.

6.Keep exercising

Exercising in moderation can go a long way in helping you reduce your lung risk. Studies have shown that even simple activities as simple as gardening can reduce the risk of lung cancer.

7.Three cups of green tea

Green tea has been shown to be effective in cell damage caused by smoking. Drinking three cups of green tea a day can effectively reduce the risk of lung cancer. But don't let that make you indulge in smoking. When you quit smoking, the positive effects of green tea in reducing the risk of lung cancer are even more significant.

1.The cough doesn't go away.

2.Coughing up blood. 3.Chest pain.

4.Hoarseness.

5.Headache. 6.Body aches.

7.Unexplained weight loss.

8.Shortness of breath.

The protective measures for lung cancer are: first, psychological counseling, second, regular check-ups to check for various syndromes, third, to prevent colds, and fourth, bedridden patients to prevent bedsores.

Because lung cancer is a wasting disease, lung cancer patients should increase their nutrient intake in their diet, eat more high-protein foods to supplement nutrition, and eat more fresh vegetables and fruits. Avoid spicy and stop smoking and drinking.

1. Do not smoke or it will lead to the worsening of the disease, and once the cancer cells spread, it is relatively difficult to control. 2. Eat a light diet, eat more fresh vegetables and fruits, and eat some cough and phlegm foods. 3. Don't stay up late and get enough sleep.

Attention transfer pain relief, which can be based on the hobbies of lung cancer patients, can also put some fast tones **, so that patients can enjoy the rhythmic clapping movements; You can also let the patient watch some jokes, humor**, or say a cross talk for fun; It can also ask the patient to close their eyes and think about their childhood fun or anything they want to think about.

You can usually listen to some brisk **, adjust your mood, and massage the acupoints when you have nothing to do. You can also use cool and pain-relieving medicines to divert your attention and do something to make you happy.

That is, you can eat more light and digestible food at ordinary times, and eat more food that can clear the lungs and protect the liver.

There are two main categories of lung cancer:

1) Small cell lung cancer: endocrine cells that arise from the lungs;

2) Non-small cell lung cancer: including squamous cell carcinoma, which arises from large airway epithelial cells;

Adenocarcinoma (including large cell carcinoma), which arises in the secretory area of the lungs;

Bronchoalveolar carcinoma, which arises from the small balloon epithelium or alveolar epithelium.

Gamma Knife is suitable for those who can't be operated on and patients who can't bear chemotherapy, you can choose Gamma Knife**, which is relatively better!

Generally, the effect is ideal for those with a diameter of less than 2cm, but it cannot be thorough for relatively large lesions.

My helpful words to you, hopefully.

Lung cancer is a malignant tumor originating from the bronchial or alveolar epithelium of the lungs, and its causes are mainly related to the environment, occupation, smoking, and genetic predisposition

1. Smoking, a large amount of evidence shows that smoking is the main factor in the occurrence of most lung cancers, and the reason is related to nicotine-derived nitrosamine carcinogens.

2. Air pollution, the occurrence of lung cancer and environmental air pollution is clear, studies have shown that adenocarcinoma is not closely related to smoking, and the increase in the incidence of adenocarcinoma may be related to air pollution, indoor decoration pollution, exposure to radioactive substances and kitchen fumes.

3. Occupational exposure, the most important occupational carcinogens of lung cancer include asbestos, crystalline silica, radon, inorganic arsenic compounds, soot, tar, and welding and painting are also constantly related to the risk of lung cancer.

4. The risk rate of lung cancer is about 25 times higher for individual patients with a family history of lung cancer.

Therefore, there are many causes of lung cancer, and it is recommended that patients must be detected early, develop good lifestyle habits.

In life, many elderly people suffer from lung diseases, and in severe cases, they will become cancerous and produce lung cancer.

This is a terrible malignant disease, and once it is detected at an advanced stage, it is very difficult to **. Since there are many types of lung cancer, some people don't fully understand them, so let me introduce you to these classifications.

It is most common in bronchial adenomas. Originates from silverophiles in the bronchial mucosa that contain neurosecretory granules. 90% of them occur in large bronchial tubes, which is a ** type tumor.

10% occur in small bronchial peripheral tumors. Lung cancer is the most common primary malignant tumor of the lung, and the vast majority of lung cancers originate from the bronchial mucosal epithelium, so it is also called bronchial lung cancer.

1. Bronchial carcinoid.

Carcinoid organisms grow under the bronchial mucosa, and when they protrude into the bronchial lumen, they form a polypoid mass with a smooth surface and abundant blood vessels, which is easy to bleed. In some cases, the tumor grows inside and outside the bronchial wall at the same time, forming a mass in the bronchial lumen and lungs, which is dumbbell-shaped. The cancer cells are small, morphologically similar, and are lined up in flakes.

Sometimes pseudoacinar is formed, the nucleus is small, the staining is deep, the cytoplasm is eosinophilic, and contains neurosecretory granules.

2. Bronchial cystic adenocarcinoma.

Also known as cylindrical adenoma, it is less common in bronchial adenoma. Originates from glandular ducts or bronchial mucosal secretory glands. Most occur in the lower trachea or proximal bronchi.

It is highly malignant and often erodes the trachea or bronchial wall and its surrounding tissues, causing obstruction of the bronchial lumen, and there may be lymph nodes or distant metastases. Tumor cells are in a sieve-like row, interwoven into columns, ** forming voids and containing eosinophilic substances.

3. Mucoepithelioid carcinoma is the least common in preparative bronchial adenoma. Originating from the bronchial mucosal secretory glands of the lobes, they are often polyp-like, with an intact superficial mucosa and secretion of mucus. Microscopic tumors consist of a mixture of squamous epithelial cells and mucus-secreting columnar cells.

Malignancy is generally low but can erode adjacent tissues.

It is divided into four main categories. Small cell lung cancer, large cell lung cancer, squamous cell carcinoma, adenocarcinoma,

Facing the reality, accepting the reality, positively**, finding a good doctor and a good method, you can be effective**If there is a condition, it is best to combine traditional Chinese and Western medicine**, which can complement each other's advantages, complement each other, treat the symptoms and root causes together, and have a better effect. Therefore, it is also necessary to establish confidence in defeating cancer. Let's face it and believe that you can beat the disease.

Lung cancer can be divided into two main categories: non-small cell lung cancer and small cell lung cancer.

Smoking and environmental factors lead to blockage of meridians, malignant changes in the physique, no matter how good the medicine is, cancer is a local manifestation of systemic diseases, Western medicine**: headache doctor, foot pain doctor, Chinese medicine can carry out systemic conditioning, improve the body's immunity; Prevent the growth of cancer cells; Kills cancer cells; J meridian tumor elimination can dredge the meridians, change the physique, the body qi and blood are sufficient, the meridians are smooth, and many diseases will naturally disappear. It is important for patients to strengthen exercise, improve their own immunity, maintain an optimistic attitude, and face the disease positively.

This is what I looked for in a book. You make a reference!

Classification: 1 Squamous cell carcinoma (squamous cell carcinoma).

2 Small cell carcinoma (undifferentiated small cell carcinoma).

3 adenocarcinoma. 4 large cell carcinomas.

5. Adenosquamous cell carcinoma. 6. Pleomorphic, sarcomatoid or sarcoma-containing carcinoma.

7 types of carcinoma. 8. Salivary gland carcinoma.

9 Unclassified cancers.

Features: 1 Squamous cell carcinoma (squamous cell carcinoma): the most common in lung cancer, accounting for about 50%, most of the patients are over 50 years old, most of them are male, most of them originate from the larger bronchi, often central lung cancer.

Although squamous cell carcinoma has different degrees of differentiation, it still grows slowly, has a long course of disease, and is more sensitive to radiation and chemistry**. Lymphatic metastases usually begin first, with hematogenous metastases occurring later.

2. Small cell carcinoma (undifferentiated small cell carcinoma): the incidence is lower than that of squamous cell carcinoma, the age of onset is younger, it is more common in men, generally originates from the larger bronchi, and most of them are central lung cancer. The cell morphology is similar to that of small lymphocytes, resembling an oat ear, so it is also called oat cell carcinoma.

Small cell carcinoma contains neuroendocrine granules in its cytoplasm, and small cell carcinoma has a high degree of malignancy, rapid growth, and extensive lymphatic and hematogenous metastasis occurs earlier. Although it is more sensitive to radiation and chemistry**, it has a poor prognosis in all types of lung cancer.

3. Adenocarcinoma: the age of onset is young, and women are relatively more common. Most originate from the smaller bronchial epithelium, most are peripheral lung cancers, and a few originate from the large bronchi.

In the early stages, there are usually no obvious clinical symptoms, and it is often found on chest x-ray, which appears as a round or oval lobulated mass. Growth is generally slower, but hematogenous metastases sometimes occur early and lymphatic metastases occur later.

4. Large cell carcinoma: This type of lung cancer is very rare, and about half of all cases originate in the large bronchi. The cells are large and the cytoplasm is abundant. The nucleus is morphologically diverse and irregularly arranged. Large cell carcinoma is poorly differentiated and is often detected after brain metastases have occurred. The prognosis is poor.
