Will lung cancer occur on both sides at the same time, and will tuberculosis in lung cancer coexist?

Hello, lung cancer is divided into two types: small cell lung cancer and non-small cell lung cancer according to its cell morphological characteristics and biological behavior.

Small cell undifferentiated carcinoma.

Small cell undifferentiated carcinoma has a cell morphology similar to oat granules, so it is also called oat cell carcinoma. It accounts for about 20% of all lung cancers. It is more common in young male patients who smoke heavily for a long time, and small cell undifferentiated carcinoma mostly originates in the larger bronchi, so most of them are type ** lung cancer.

Small cell undifferentiated carcinoma tissue has a low degree of differentiation and rapid growth, and lymph node metastasis and hematogenous metastasis can occur in the early stage, and the lymph node metastasis is extensive, and the volume of metastatic lymph nodes is often larger than that of the primary lung lesion. Distant metastases are brain metastases and bone metastases being the most common. Small cell undifferentiated carcinoma has the worst prognosis of all lung cancer types.

Highly sensitive to radiation** and chemical**, but the vast majority of tumors** develop after cessation**. The regimen for small cell anaplastic carcinoma is significantly different from that of other types of lung cancer, emphasizing systemic chemotherapy as the mainstay, supplemented by local radiotherapy or surgery. Answer from-Doctor of Shanghai Zhongda Cancer Hospital.

Non-small cell lung cancer.

With the exception of small cell undifferentiated carcinoma, other types of lung cancer are collectively referred to as non-small cell lung cancer.

Hello, lung cancer is generally divided into three types, lobular pneumonia, lobar pneumonia and myopia lenses, small cell lung cancer is generally more malignant, it is difficult to be thorough, you can go through surgery, late chemotherapy, **.

There will be such a possibility.

Moreover, pulmonary tuberculosis has an indirect effect on the occurrence of lung cancer, and the calcification of pulmonary tuberculosis, alveolar epithelial cell proliferation, old cavitary wall and bronchi, tuberculous scarring, proliferation, etc. are related to the occurrence of lung cancer.

How old is your father-in-law, he is too old, so it's best not to toss. In terms of diet, as long as the elderly want to eat, they can eat it, and they don't have to worry too much.

Imaging examination has a high clinical application value in the differentiation of lung cancer and pulmonary tuberculosis, and its imaging difference is that there will be satellite foci around the lesion tissue in typical pulmonary tuberculosis patients, and CT shows regular and smooth thin-walled cavities at the inner edge, and a few nodules and burrs, and signs of pleural effusion.

The main inducing factor of lung cancer is the liquefaction and necrosis of the chest mass in patients, resulting in lung cancer cavities, and there is generally no difference in the thickness of the cavity wall. CT showed that the cavity wall was irregular and rough, some of which also had wall nodules, dilated blood vessels around the lesion, and obvious vascular visualization. Due to the influence of the lobular structure of the surrounding tissues, the distribution of the diseased tissues is lobulated, and there are dense short burrs in lymphatic vessels and other parts, which are quite different from the sparsely distributed burrs of uneven thickness in pulmonary tuberculosis patients.

In 1932, Warren and Gates revised and relaxed the criteria, and combined with the domestic Liu Fusheng, the criteria were as follows: that is, every tumor must be histologically malignant; Each tumor has its own pathological morphology; Each type of tumor occurs in a different site or organ; Metastatic cancer or ** cancer must be excluded.

Some scholars refer to two or more primary malignant tumors occurring in different parts of the same organ as multiple primary malignant tumors, and primary malignant tumors occurring in more than two organs are called duplicate cancers. However, most of the literature considers duplicate carcinoma and multiple primary malignancies to be the same disease. Multiple primary malignancies can be found in the same organ, paired organs, the same system, and different systems.

Therefore, a person who meets the following criteria can be diagnosed with multiple primary cancers.

Each tumor is malignant; The characteristics of the metastatic pathways are different;

Microscopy is different for each tumor;

There is sufficient evidence to rule out metastatic cancer.

2. Identification of multiple cancers.

Simultaneous multiple cancers: 6 months apart for simultaneous multiple cancers.

Metachronous polycarcinoma: Metachronous polycarcinoma with an interval of 6 months.

Characteristics of multiple cancers: easy to misdiagnose, often found in one part of the tumor at the beginning of the diagnosis**, found two parts of the tumor, the second tumor according to the metastasis**.

Identification methods: imaging differentiation and pathological differentiation (including gene sequencing) I will not discuss these things, and leave them to the professional cancer team.

Incidence of multiple cancers: The incidence of MPC is related to medical resources in foreign countries and countries, and the incidence is also related to the region and living and working environment, so it will not be discussed here. Digestive tract tumors and breast tumors are common, but MPCs with different pathologies of the left and right lungs and left and right breasts are common.

The respiratory and digestive tracts are common in men, and the endocrine and reproductive systems are common in women. The incidence of MPC is also related to the medical environment and region, and the probability of finding a place with a good medical environment is high, and the characteristics of regional cancers will also correspondingly increase the probability of multiple cancers, such as nasopharyngeal cancer in Guangdong and lung cancer in Hebei.

Regarding prognosis: multiple primary malignancies and metastases are very different in terms of prognosis and prognosis. Poor prognosis is often not related to the degree of malignancy of the tumor, but to the appropriate **, and misdiagnosis is a common error.

Polycarcinoma and genetic constitution: The occurrence of polycarcinoma is more common in familial, and this inheritance mode is related to mutations in autosomal dominant genes, such as the susceptibility gene BRCA1 2, and the risk probability of developing a second tumor within 10 years in patients with this gene mutation has been written into the NCCN guideline, which should be a mandatory item for breast cancer and ovarian cancer.

Radiotherapy and the second tumor: Radiotherapy is one of the necessary means for cancer patients, how do we understand radiotherapy for the second tumor or secondary tumor? Theoretically, the probability of developing a tumor ten years after normal radiation** is certainly increased, but there is no evidence of evidence-based medicine.

Largely, the metastasis and spread of cancer will cause multiple cancers, but 90% of cancers can be **.

Some people will develop more than two cancers in different organs or different types of tissues at the same time, these cancers are unrelated, its tissue type, location and nature are different, and it can have its own metastases, which is called multiple primary cancer in medicine. Why does the same person develop two cancers at the same time? Some people believe that cancer patients have 11 times the chance of developing a second type of primary cancer than normal people.

Second, carcinogens act on different organs. For example, after smoking, the carcinogens in tobacco act on the larynx and lungs, causing laryngeal cancer and lung cancer; Carcinogens act in the digestive tract, causing stomach and colorectal cancers. the third is to repeatedly receive isotope or radiation diagnosis and **, and isotopes and radiation themselves are carcinogenic; For example, cervical cancer occurs after radiotherapy due to rectal damage to the rectum, and breast cancer develops lung cancer after radiotherapy.

Fourth, chemotherapy and surgery can cause acquired immune deficiency, that is, the loss of resistance to cancer, thus promoting the formation of another new primary cancer. Fifth, genetic factors, in families with a high incidence of cancer, there are more patients with multiple primary cancers. Sixth, occupational factors, people who have been exposed to carcinogens for a long time have more primary cancers.

Seventh, with the improvement of diagnosis and treatment and the improvement of life, the survival time of cancer patients is prolonged, and the average life expectancy of people is also extended, which provides the possibility for the occurrence of multiple primary cancers. At present, more attention has been paid to the prevention of cancer and metastasis, but little is known about multiple primary cancers. When two types of cancer occur at the same time, especially when the symptoms of one cancer are obvious and the other is not obvious, it is easy to miss the diagnosis, which will delay the disease and even make the patient lose the opportunity.

Therefore, histopathological examination is necessary for patients with suspected multiple primary carcinoma to prevent missed diagnosis.

Of course. There are even more than two ... Because some cancers are the root cause of metastasis, and there is also a problem with some parts of the body.

In general, two cancer foci, one is primary and the other is metastasized, which needs to be treated as soon as possible to improve the quality of life of patients and prolong life. Traditional Chinese medicine can be used**.

Guidance:

The commonly used methods for lung cancer are: surgery, chemistry, radiation, targeting, immunization, traditional Chinese medicine and a combination of different methods. **Protocols are dependent on the classification and staging of tumors.

For patients with advanced lung cancer, systemic chemotherapy should be the main option, and palliative surgery and radiotherapy can also be appropriately selected.

Lung cancer occurs in the bronchial mucosal epithelium, also known as bronchial lung cancer. Lung cancer generally refers to cancers in the parenchymal part of the lungs, usually not including other pleural tumors of mesothelioma, or other malignant tumors such as carcinoids, malignant lymphomas, or metastases from other tumors. Therefore, the following lung cancer refers to malignant tumors from bronchial or bronchiolar epidermal cells, accounting for 90-95% of lung parenchymal malignant tumors.

Lung cancer is currently the number one cause of cancer death worldwide. In 1995, 600,000 people died from lung cancer worldwide, and the number is increasing every year, and in 2003, the World Health Organization (WHO) announced a mortality rate of 1.1 million years and an incidence rate of 1.2 million years. The incidence of lung cancer in women is particularly rising.

The disease usually occurs over the age of 40, and the peak age of onset is between 60 and 79 years old. The prevalence in both sexes is: 1.

In addition, ethnicity, family history, and smoking all play an important role in the incidence of lung cancer.

Lung cancer originates from the bronchial mucosal epithelium and is confined to the basement membrane, which is called carcinoma in situ, which can grow into the bronchial lumen or adjacent lung tissues, and can spread through lymphatic hematogenous or transbronchial metastasis. The growth rate and metastasis of cancer tumors are related to the biological characteristics of cancer tumors, such as histological type and degree of differentiation.

The distribution of lung cancer is more in the right lung than in the left lung, and the upper lobe is more than the lower lobe, and cancer can occur from the main bronchus to the bronchioles. Lung cancer originating from the main bronchial tube, lobe bronchi, located close to the hilum of the lungs, is called ** lung cancer; Lung cancer that originates below the bronchi of the lung and is located in the surrounding part of the lung is called peripheral lung cancer.

The incidence of lung cancer in the right lung is slightly higher than in the left lung, and the incidence of lung cancer in the upper lobes is also relatively high. In the past, it was thought that most lung cancers occurred in the large bronchi, but in recent years, it has been found that more and more lung cancers originate in the peripheral part of the lungs. The incidence of lung** lung cancer and peripheral lung cancer has decreased from 2 1 in the past to nearly 1 1 now.

Lung cancer occurs in the bronchial mucosal epithelium, also known as bronchial lung cancer. At the same time, when lung cancer cells continue to spread and metastasize, metastasis to other sites, such as bone metastasis and lung cancer brain metastasis, are common phenomena.

Lung cancer can be classified according to the anatomical location, and can be divided into ** type lung cancer and peripheral lung cancer. The bronchi that occurs in the segment and above the segmental bronchial opening, and is located close to the hilum is called ** type lung cancer, such as squamous cell carcinoma, small cell carcinoma, carcinoid carcinoma, etc. The distal bronchi and bronchioles that occur below the segmental bronchi and are located in the surrounding part of the lungs are called peripheral lung cancers, such as most adenocarcinomas.

Lung cancer is a malignant tumor of the lungs, which is generally found in the hilum or around the lungs, and can only be diagnosed by needle biopsy.

I've only heard that colds are contagious, but I've never heard that lung cancer is contagious, and smoking is definitely one of the conditions for lung cancer.
