Fluid in the lungs is a broad term to describe two possible states that can give characteristic symptoms, such as a bubbling noise in the lungs (rattling) when breathing. Fluid accumulation may be in the lungs (pulmonary edema) or outside the lungs (pleural effusion), in the space between the lungs and the chest wall. The term fluid in the lungs is also used in the lungs to refer to mucus. Mucus or phlegm is really a thick, sticky secretion even though lung water is a thin fluid. Other fluid accumulation can be the result of blood or pus.

The lungs enter the thorax (chest) and lie on either side of the heart. Air travels through the air passages that surround the nose, throat (neck), trachea (trachea) and bronchi. The lung tissue is made up of small air sacs, known as alveoli, which is thin and surrounded by blood capillaries. The structure of the respiratory system allows an exchange of gases, so that essential oxygen is taken into the body and waste products, along with gases, are excreted by the exhaled air. The lung is enclosed in an airtight pleural cavity, with a small pleural space separating the lungs from the chest wall. This cavity is lined by the pleural lining, which also creates a small pleural fluid to reduce the friction between the chest wall and lungs while breathing.

Fluid in the lungs

The most common cause of fluid in the lungs is mucus or mucous produced by the lining of the airways. The airway is lined with a mucous membrane that produces a specialized tissue that produces mucus. This mucus lubricates the lining, which can dry out due to the movement of air and out of the channels as well as stopping dust or microorganisms in the air. However, under certain conditions, the mucous membranes of the respiratory tract can generate excessive amounts of mucus and this can slowly sink down the air ducts until it settles in the lungs. The cough reflex or even spontaneous coughing will usually expel most mucus through the mouth (sputum), but in cases of excessive mucus production, obstructive airway disease or diminished cough, the build-up of mucus will quickly settle in the lungs.

Lung water or water in the lungs usually results from the interstitial fluid or blood plasma and may be an indication of a serious underlying condition, usually cardiovascular disease. This fluid in the lungs is known as pulmonary edema and may be accompanied by shortness of breath or shortness of breath (dyspnoea), a feeling of suffocation, anxiety, and restlessness. Abnormal breathing sounds are also present, especially crackling. Pulmonary edema could be considered a medical emergency and really immediate medical intervention is necessary.

Blood can also fill in the lungs, but this usually happens as a result of severe trauma and the cause is evident, as in a shot or puncture wound. In most trauma cases, where blood can fill the lungs, the lungs collapse and the blood in the lungs collects in the chest cavity (hemothorax). Infections such as tuberculosis (TB) or lung cancer can also lead to blood accumulation in the lungs. Depending on the severity of the trauma, blood in the lungs will cause drowning and requires immediate medical attention. Pus can also occur in the lungs due to a lung abscess and also requires immediate urgent medical attention.

Causes of the fluid inside the lung

  • Bronchitis is the most common cause of mucus in the lungs and is often characterized by persistent cough. This respiratory disease can develop after the common

Cancer therapies serve the purpose of curing the patient of the disease (“curative” = healing therapy) or to stop the further growth and spread of the tumor as long as possible, to relieve discomfort and to prolong the lifetime (“palliative” = alleviative) Therapy). An indispensable component of oncological care is the so-called “supportive therapy” (supportive therapy). It treats and prevents complications of cancer and survival-related but often aggressive cancer therapies.

How is lung cancer operated?

If the tumor has not exceeded a certain size and has not yet formed distant metastases, surgery is sought with the aim of completely removing the tumor tissue and the lymph nodes affected by tumor cells. The operation plays an important role especially in non-small cell lung cancer – as small cell lung cancer is often diagnosed at a later stage, then other treatments are in the foreground.

The surgical procedure is preceded by extensive research. In particular, it must be ensured that after the removal of part of the lung, the remaining lung sections are able to sufficiently take over the respiratory function. The condition for the operation is a good general condition of the patient; Severe comorbidities often rule out surgery. Furthermore, removal of the tumor should not pose a risk to neighboring vital organs such as large blood vessels or the esophagus. If the expected burdens and restrictions are too great, a different therapy strategy must be chosen.

During surgery, the tumor-bearing lung section and the adjacent lymph nodes are removed. The most common procedure is the removal of a lung lobe (lobectomy). With very large tumors the removal of an entire lung wing may be necessary (pneumectomy). In many cases, however, it is possible to avoid the removal of the entire lung through special, organ-preserving surgical techniques.

Possible side effects:

As a result of the operation, the available breathing area of the patient is reduced. However, if the lung function before surgery is sufficient, it will not be a major problem for the patient, and he will usually be able to compensate well for the loss of lung tissue. Special breathing exercises in rehabilitation also help to improve lung performance after tumor therapy. The first exercises can already be learned in the clinic under the guidance of a physiotherapist and later be continued at home. For smokers, however, they should stop smoking immediately before the operation to improve their lung function.

What happens during an irradiation?

Radiation therapy is the only therapy for non-small cell lung cancer in stages I and II when surgery is not possible and for selected patients in stage III. Otherwise, it is usually combined with chemotherapy in patients with stage III and small cell lung cancer. If cancer has secondary tumors, called metastases, in other organs such as the brain or the bones, they may also be irradiated.

The high-energy ionizing radiation, which is directed from the outside to the tumor, destroys the cancer cells. The total radiation dose is divided into several single doses, which are administered about five times a week. In the so-called hyperfractionated radiation, which can be used in lung cancer, is even twice a day at intervals of several hours, but then irradiated with lower single doses.

In addition to conventional radiotherapy, the so-called stereotactic radiotherapy is also used. Here, the disease is in a few sessions, sometimes in only one, irradiated with a high dose of radiation. This is possible because the beams are directed to the target area from different directions after computer-controlled irradiation planning. There, all the rays meet at one point and add up to the total dose, which is thus maximum at the site of the disease, while the surrounding healthy tissue is largely spared. For this reason, stereotactic radiotherapy is particularly well suited for small tumors and tumors in delicate environments, such as brain metastases.

Possible Side Effects:

Side effects of radiotherapy may be hoarseness and difficulty swallowing. The skin is also sensitive to the treatment. In combination with chemotherapy in particular, mucous membrane inflammation and fungal infections can occur in the oral cavity. A late consequence is a pneumonitis, an inflammation of the irradiated lung tissue. Overall, the severity of side effects depends on the type and intensity of the radiation used.

How does the chemotherapy work?

Chemotherapy uses cell-growth-inhibiting drugs known as cytostatics. They act primarily against fast-growing cells and thus especially against cancer cells. For the treatment of lung cancer several chemotherapeutic drugs are available, which are selected according to individual requirements.

Which medicines are used depends on various factors, including the stage of the disease, the general condition, and concomitant diseases. Usually, two or three substances are combined, with cisplatin or carboplatin as the basic drug in most cases. Commonly used cytostatic drugs in non-small cell

To assist physicians in deciding what type of treatment is more appropriate for lung cancer, there is a recognized numerical staging system that creates benchmarks. At Stage I, the cancer is small and localized in a specific area of the lung. During phases 2 and 3, cancer grows and spreads to the surrounding tissue and possibly the lymph nodes.

Stage 4 of lung cancer is when cancer has spread, or metastasized, from the lungs to other parts of the body. Typically, cancer spreads to the liver, bones, brain or adrenal glands. This is commonly known as secondary or advanced cancer. About 40% of lung cancer patients are diagnosed at stage 4, mainly because the symptoms of lung cancer could include symptoms of other diseases. In Stage 4, the cancer is not curable, but it can be treated. These are some of the symptoms that may help your doctor to diagnose stage 4 of lung cancer.

  • Breathing problems

Lung cancer patients often present with shortness of breath, wheezing, and hoarseness. It is often a persistent cough, and the patient can cough up blood. Sometimes, a chronic cough that the patient may suddenly change for some time may be natural. Because these symptoms may also affect other conditions, they are not sufficient to suggest a diagnosis of lung cancer. However, if a smoker presents with these symptoms, a diagnosis of stage 4 lung cancer is likely to be considered by the doctor.

  • Pain

Patients may experience pain in various areas of the upper body, including the back, chest, arms, ribs, and hips. Deep breathing often intensifies the pain that can be felt in the tissues or bones depending on the spread of cancer. It can also be a pain when swallowing. Some people suffer from frequent headaches, which is an indication that cancer could be affecting the brain.

  • Weight Loss

With stage 4 lung cancer, there is often a sudden, unexplained weight loss that is often accompanied by loss of appetite and a general feeling of weakness and fatigue. If this weight loss is significant and you do not have a diet, it should be investigated.

  • “Clubbing”

The nails on the fingers and toes can bulge, and the ends of the fingers change shape. This symptom usually develops in the latter stages of lung cancer, so it is a good indicator of diagnosis.

  • Diagnosis

The diagnostic process for stage 4 lung cancer is usually some form of imaging, such as computed tomography (CAT) or Magnetic Resonance Imaging (MRI). These scans give a detailed picture of the spread of cancer as X-rays, allowing the doctor to determine the cancerous stage. A radionuclide scan can detect if cancer has spread to other organs, while a bone scan will show if the bones are affected.

The doctor may also conduct tests to determine if cancer has spread to the lymph nodes. This involves removing a tissue sample for testing under general anesthesia. This process is called medias or mediastinotomy, depending on whether the tissue is absorbed by the neck or the chest.

While all these symptoms refer to other conditions, if you experience one or more of them for two weeks or more, you should consult your doctor. Lung cancer is particularly dangerous because of it metastases to other parts of the body relatively quickly, making it one of the most life-threatening cancers there is. As with most conditions, the earlier the diagnosis, the more likely that the treatment will succeed. During treatment for stage 4 lung cancer, the condition will not heal, it can prolong life and improve quality of life, so it is important to seek medical advice as soon as possible.

Lung cancer is a malignant neoplasm in the respiratory system (lungs and bronchi). In addition to breast cancer, colon cancer and prostate cancer, it is one of the most common cancers worldwide. Unfortunately, the number of illnesses continues to increase, especially among women.

Short version:

  • Smoking causes 85% of lung cancers.
  • Lung cancer is caused by a change in the genetic material due to chronic damage.
  • Lung carcinomas can be divided into two groups.
  • Because symptoms are unrecognized or misinterpreted, lung cancer is often discovered by accident during examinations.
  • The treatment of a lung tumor depends on the type of cancer.

In Austria, around 2,500 men and almost 1,200 women suffer from bronchial carcinoma each year. Thus lung cancer is second only to prostate cancer in males and third in women after breast and colon cancer. Most cases are detected between the 55th and the 65th year of life. However, patients can be significantly younger.

The main risk factor for the development of lung cancer is cigarette smoking: Around 85% of all cases can be attributed to tobacco consumption. Hereditary predispositions or contact with other harmful substances (such as arsenic, radon or asbestos), on the other hand, play a subordinate role. 3-5% of the diseases are caused by passive smoking.

From surgery to Targeted Therapy: Depending on the type and stage, lung cancer is treated differently.

Anyone smoking a pack of cigarettes every day for over 20 years increases their lung cancer risk 30 to 40 times. By contrast, a familial accumulation only leads to a doubling or tripling of the risk.

How does lung cancer develop?

In the cells of the mucous membranes of the bronchi and in the alveoli, there is a change in the genetic material due to prolonged chronic damage (for example, chronic inflammation from cigarette smoke). After a long time, this change means that the normal control mechanisms for the growth and death of cells are no longer effective and a malignant tumor develops. At an early stage of development, this process can sometimes be reversed, such as when the damaging effects are stopped.

Basically, two groups of lung cancer are differentiated:

  1. Non-small cell lung carcinoma

The non-small cell type accounts for around three quarters of cancers of the lung. It is roughly subdivided into:

  • squamous cell carcinoma
  • the adenocarcinoma
  • the large cell carcinoma
  1. Small cell lung carcinoma

Small cell lung cancer (about 20% of the disease) spreads rapidly through the bloodstream and lymphatics, but is better for chemotherapy.

This distinction is important from a medical point of view, because the therapy is targeted accordingly.

Which symptoms occur?

In those cases of lung cancer that are discovered at an early stage, these are generally incidental findings: pulmonary x-raying is actually done for quite different reasons, e.g. in case of release for surgical procedures or severe infections suggesting pneumonia.

The most significant problem is that the disease remains asymptomatic for a long time. Often, the typical symptoms, such as coughing, shortness of breath, fatigue or back pain, misinterpreted or ignored. Since the majority of sufferers are smokers with chronic bronchitis and often have cardiovascular problems, the symptoms are attributed to them.

A doctor’s visit is therefore often delayed for a long time. Only the appearance of blood in the sputum or severe weight loss are alarming. More than two-thirds of all cases of lung cancer are therefore diagnosed at a local or systemic (i.e., distant metastasis) stage.

Unfortunately, previous large-scale studies on the possibility of early diagnosis have not shown sufficiently satisfactory results to be meaningful to broad sections of the population. A so-called spiral computed tomography (spiral CT) with low radiation dose is therefore recommended as a preventive check only certain risk groups: chronic smokers over 50 years, especially if at the same time a chronic obstructive pulmonary disease (COPD) is present; in addition, in the case of lung cancer in the family or a workplace that is burdened by inhaled carcinogens (carcinogenic substances). However, the last two factors only seem relevant if the person smokes himself at the same time.

How does the doctor make a diagnosis?

If lung cancer is suspected, the patient is referred to a specialized department where a complete examination is made as soon as possible. Among other things, the stage of the disease, the type of tumor and the spread in the body is examined.

For this purpose, different examination methods such as computed tomography, ultrasound, biopsy or a PET scan are performed.

Which treatment methods are available?

The choice of treatment for lung cancer depends largely on the type of cancer and the stage of the cancer. Treatment options range from surgery to radiation and chemotherapy, to molecular biology therapy.

What is the prognosis for lung cancer?

In contrast to other types of cancer, in the case of bronchial carcinoma, there are no meaningful early detection measures or long-term successful treatment methods. Lung cancer is the only cancer in which the rate of new disease is nearly identical to that of deaths.

Taking all the cases together, current treatment methods achieve a 5-year survival rate of only 15%. However, when early-stage non-small cell lung cancer is detected, around 75 out of every 100 people treated surgically are still alive five years later.

At the same time, lung cancer is virtually the only cancer that has a prevalent and avoidable risk factor. Prevention through smoking cessation is therefore at the forefront.
