CT examination for early symptoms of lung cancer, early symptom diagnosis of lung cancer

In a 23-year-old man, it is normal for the breast to have a small gland, and CT is very accurate in judging nodules and masses in the lungs, and MRI is only slightly more accurate in judging mediastinum. Based on my more than 20 years of work experience, you should be fine, at most a re-examination of the CT is sufficient. As for the small blood streak in the sputum, it may be caused by the rupture of a small capillary, and there is no major problem.

Hopefully, this medicine will help patients.

CT is a very fast and convenient diagnostic method that can be used to diagnose a variety of cancers. EGFR is a protein tyrosine kinase receptor that is often overexpressed in NSCLC and plays an important role in tumor cell proliferation, invasion, metastasis, and inhibition of tumor cell apoptosis. EGFR mutant type** is significantly more effective than EGFR wild type.

EG-FR-TKI is small and can be tolerated by most patients.

However, in the process of using CT diagnosis, there are still some basic precautions: 1. Read the chest CT enhancement scan carefully, be sure to distinguish between vascular enhancement and lesion enhancement, and it is best to choose the largest layer of the lesion as the puncture target; 2. Try to take the part around the tumor tissue. Generally, do not take the central part of the tumor.

Pathological diagnosis is difficult because the central part of the tumor, especially large tumor, often causes hemorrhage and necrosis. 3. The action should be gentle and try to shorten the time of each puncture; Puncture the tissue at one time to avoid repeated punctures in a see-saw style. It is important that disposable semi-automated biopsy needles can only be used once.

Blood tumor markers can be checked.

It is not possible to determine whether it is cancer or not, and the possibility of cancer according to your description is not very large, so it is recommended to do a comprehensive examination and make an early diagnosis.

Hello, what you said is not easy to judge, it is recommended that you do an MRI to make sure. If you are really unfortunate enough to suffer from lung cancer, it is recommended that you consult about the most advanced technology available for tumors, spiral tomography radiotherapy, and it is best to use this for treatment**.

The common symptoms of lung cancer are mainly as follows:

1. Unexplained intractable pain in joints and muscles, **numbness, burning, fever, but systemic symptoms are not obvious.

2. Have a history of long-term smoking; History of cancer in family lineage; People who are exposed to carcinogens such as asbestos, asphalt, arsenic, chromium, coal tar, etc., and who have respiratory symptoms.

3. No chills and fever, sudden and progressive shortness of breath, chest tightness, and pleural effusion on chest X-ray.

Fourth, the chest X-ray shows "lung inflammation", which cannot be completely controlled, and the symptoms recur or aggravate.

5. Aged over 35 years old, prolonged cough, especially frequent and persistent coughing, the cause cannot be found in a short period of time.

6. After a cold or bronchitis, the cough does not heal for a long time and the symptoms gradually worsen.

7. Recurrent hemoptysis and intermittent chest pain.

8. Known as tuberculosis and chronic bronchitis, the original cough pattern suddenly changed.

If CT is fine, then the possibility of lung cancer is relatively small.

If you are not at ease, then there is a ruthless method, but no one dares to do it: that is, cut off both lungs for pathological examination.

Hello, early symptoms of lung cancer include cough, low-grade fever, chest pain, phlegm and blood, late symptoms of facial and neck edema, hoarseness, weight loss, fever, anemia, pleural effusion and other symptoms. X-ray, CT, MRI, fiberoptic bronchoscopy, sputum exfoliated cell examination, biopsy and other diagnostic tests can be done.

For cancer, it is recommended to have regular check-ups, develop a good lifestyle habits, and quit smoking and drinking.

Lung cancer is a very serious lung disease, once the disease is easy to develop into advanced lung cancer, so once we have lung discomfort in our daily life, we must go to a regular hospital for examination in time, in order to strive for early detection and early development. So how to check and diagnose lung cancer in the early stage, let's take a detailed look at it below. Experts say that lung cancer is very harmful, and early detection is the key.

The early detection of lung cancer is the most important factor in determining the prognosis, most of the patients with advanced lung cancer die within 1 year, and the 5-year survival rate of early lung cancer can reach 60% to 90% after surgery**and comprehensive**, so the diagnosis of early lung cancer is the key to lung cancer. When patients come to the hospital with symptoms of cough, chest pain and hemoptysis, they are diagnosed as at an advanced stage, and domestic and foreign data show that once the lung cancer patients are diagnosed by pathology, 80% of them are already at an advanced stage. Unfortunately, many early-stage lung cancers do not have any symptoms or the symptoms are mild enough to attract the attention of patients and miss the opportunity to diagnose early-stage lung cancer.

Lung cancer can be diagnosed at an early stage by taking a chest x-ray or chest CT. Chest x-ray can be used to diagnose lung cancer, which is better and safer than chest fluoroscopy, and if chest x-ray is abnormal, chest CT examination should be done further, tumor cells should be found in sputum, and flexible bronchoscopy should be done if necessary. It is worth mentioning that chest x-ray is not a panacea, and some early-stage lung cancers do not have abnormal manifestations on chest x-ray, and there are some "blind spots", which should be closely followed-up.

Chest CT is more effective in detecting peripheral lung lesions than ordinary chest x-rays. The literature has reported that low-dose CT is 10 times more sensitive than ordinary chest x-ray for detecting small nodules in the lungs. Therefore, some scholars have suggested that smokers over the age of 60 should undergo annual low-dose spiral CT screening.

In addition, percutaneous fine needle aspiration biopsy is extremely accurate in diagnosing malignant pulmonary nodules, with a sensitivity of 70% to 100%, but it is invasive and has certain complications, such as pneumothorax and hemoptysis. The above is the method of early detection and diagnosis of lung cancer.

The early symptoms of lung cancer are not easy to find, and most of them are found in the middle and advanced stages, and patients with advanced lung cancer are more serious and most of them will metastasize. Because there are many metastatic sites of lung cancer and more ways of lung cancer metastasis, it will be very difficult to prevent it at present. For example, the main thing about cancer is to control the spread of cancer cells and improve one's own immunity.

In the early stage of lung cancer, there are the following symptoms: 1. Low-grade fever accompanied by cough and wheezing, similar to wind heat.

2. Cough up sputum with blood streaks or blood clots.

3. Chest tightness, occasionally accompanied by radiating pain, such as the back.

Early symptoms of lung cancer include cough, hemoptysis, chest and back pain, stridor, and unexplained fever.

We know that lung cancer is a malignant tumor that occurs in the lungs of our respiratory organs, so the symptoms are closely related to the location of its occurrence.

Generally speaking, lung cancer is divided into ** type lung cancer and peripheral lung cancer, ** type lung cancer generally has slightly earlier symptoms, because it occurs in the main bronchi, cough, phlegm blood or chest discomfort appear earlier. The peripheral type may be found at the time of discovery, once the tumor accumulates to the pleura, there will be changes in chest pain, and if it develops again, pleural lesions will appear, resulting in pleural effusion.

SPAN is very unstable in the development of lung cancer patients, and it is recommended to go to a regular hospital for further examination as soon as possible. The specific situation needs to be carried out according to the recommendation of the attending doctor**, mainly surgery, radiotherapy, chemotherapy, traditional Chinese medicine**, biology**, etc. /span

Hello, glad to answer for you. The clinical manifestations of lung cancer are generally complex, and the presence, severity, and early occurrence of symptoms and signs depend on the location of the tumor, the type of pathology, the presence or absence of metastasis and complications, as well as the difference in the degree of response and tolerance of patients. Early symptoms of lung cancer are usually mild or may not cause any discomfort.

**Type lung cancer symptoms appear early and severe, peripheral lung cancer symptoms appear late and mild, it is recommended to go for relevant examinations, early detection and early**, thank you!

Hemoptysis or bloody sputum, fever, nosebleeds, headache, cough, chest pain (recommended for Sino-American Diagnosis and Treatment Center, Peking University Cancer Hospital).

Early-stage lung cancer is generally difficult to detect because its symptoms are not obvious. In the early stage, there may be symptoms such as cough, shortness of breath, and blood in the sputum, and in the late stage, patients may have fever, emaciation, and fatigue.

If there are early symptoms of cancer, it must be diagnosed early, as early as possible.
