Introduction

A lung nodule measuring 45 mm is very serious and must be surgically removed as soon as possible. If it is a solitary malignant pulmonary nodule, typically with a diameter greater than 3 cm, it indicates early-stage lung cancer, also known as carcinoma in situ or non-invasive adenocarcinoma of the lung. After complete surgical resection at an early stage, the prognosis is generally favorable.

A lung nodule measuring 45 mm is very serious and must be surgically removed as soon as possible for treatment.

If it is a solitary malignant lung nodule, the nodule typically has a diameter greater than 3 cm and represents an early stage of lung cancer, also known as carcinoma in situ or non-invasive adenocarcinoma. Complete surgical removal at an early stage can lead to a favorable prognosis. After surgery, adjuvant radiotherapy and chemotherapy may be required. Radiotherapy is generally used for patients with locally advanced disease, advanced age, or compromised cardiopulmonary function who are unable to undergo surgery, or for those after surgical treatment. Radiotherapy can prolong survival but does not achieve curative results. Chemotherapy aims to kill malignant lung nodule cells through oral or injected chemotherapeutic agents, although it often comes with significant side effects.

The following precautions should be observed during the management of pulmonary nodules:

1. If follow-up examinations reveal rapid growth of the lung nodule, it may indicate cancer, and timely interventions such as surgery, chemotherapy, or radiation therapy should be initiated.

2. In daily life, patients with lung nodules should quit smoking and avoid exposure to dust in both daily activities and work environments. Wearing a mask when going outdoors during seasons with poor air quality is strongly recommended.

3. Maintain a light diet rich in brightly colored, fresh vegetables and fruits, and consume high-quality proteins such as milk, soy milk, eggs, nuts, and lean meats like chicken breast and duck breast to ensure adequate and balanced nutrition.

What causes a nodule in the upper lobe of the left lung?

The nodules in the left upper lobe of the lung are mainly caused by infectious factors, benign tumors, pulmonary fibrosis, vascular abnormalities, and malignant lesions. If a nodule is detected, timely evaluation with chest CT, tumor markers, and other tests should be performed to determine its nature. Infectious factors: Pathogens such as bacteria, viruses, and fungi cause localized inflammation; after the inflammation resolves, tissue repair may result in scar-related nodules.

What is the difference between a lung nodule and a tumor?

The core differences between pulmonary nodules and tumors are reflected in aspects such as definition, nature, imaging characteristics, clinical significance, and management principles. If an abnormal lung shadow is detected, it is recommended to seek timely evaluation and examination at a respiratory or thoracic surgery department. A pulmonary nodule is an imaging term referring to a round or nearly round space-occupying lesion in the lung with a diameter ≤3 cm.

What does it mean when the maximum CT value of a pulmonary nodule is 105 HU?

A lung nodule with a maximum CT value of 105 Hounsfield units (Hu) indicates relatively high density, close to calcification or containing substantial dense components. Such nodules are mostly benign, such as old tuberculosis lesions, inflammatory scars, or calcified nodules. However, further evaluation is still needed to rule out rare malignant possibilities. It is recommended to visit a pulmonologist or thoracic surgeon promptly. CT value is a measure of tissue density.

What Chinese herbal medicines should patients with lung nodules take?

In general, patients with pulmonary nodules may use traditional Chinese herbs for regulation under the guidance of a physician. Commonly used herbs include Prunella vulgaris (Xia Ku Cao), Zhe Bei Mu, dandelion, Hedyotis diffusa (Bai Hua She She Cao), and Salvia miltiorrhiza (Dan Shen). In addition, other suitable Chinese herbal medicines may also be combined under medical supervision. During treatment, patients should undergo regular follow-up examinations, maintain a light diet, avoid smoking and alcohol consumption, and minimize irritation to the lungs.

Is Maytenus effective for lung nodules?

Maytenus is a plant, and some traditional practices have mentioned its potential anti-inflammatory and mass-dispersing effects. However, these claims lack sufficient clinical evidence. Currently, there is no authoritative evidence indicating that Maytenus can directly reduce or eliminate pulmonary nodules, and it has not been included in standard treatment guidelines for pulmonary nodules. Its effects on nodules remain largely theoretical.

Will lung nodules grow larger after receiving a COVID-19 vaccine?

If the pulmonary nodule is benign and there are no contraindications such as vaccine allergy or acute infection, vaccination will not stimulate the nodule to grow. COVID-19 vaccines primarily work by stimulating the immune system to produce antibodies; they do not directly affect lung nodules nor alter their nature or growth trend. Standard vaccination is considered safe.

What should I do if a lung nodule is detected during evaluation for cough?

A lung micro-nodule discovered during evaluation of cough requires management strategies including determining the nodule's characteristics, assessing its relationship with the cough, following established surveillance guidelines, adjusting lifestyle, and implementing targeted interventions. Most pulmonary micro-nodules are likely benign, so excessive anxiety is unnecessary. However, if the nodule has irregular morphology, increases in size, or if the cough is accompanied by hemoptysis or weight loss, prompt medical consultation is recommended.

Which is more serious: kidney cysts or lung nodules?

The severity of renal cysts and pulmonary nodules cannot be generalized. Overall, malignant pulmonary nodules are more serious. Benign renal cysts and benign pulmonary nodules are both mild conditions, whereas malignant lesions carry a significantly higher risk of progression compared to benign ones. If either condition is detected, or if symptoms such as coughing, hemoptysis, or abdominal pain occur, prompt medical evaluation is recommended to determine the nature of the lesions.
