What is Lung Cancer?

Lung cancer is roughly always caused by cigarette smoking. Many times it's not diagnosed until the later stages of the disease which regularly means that it has already spread to other tissue and organs. It's also the important cause of cancer deaths in the Us in both men and women which is sad as the risks of developing it significantly decrease if a someone does not smoke.

What are the early warning signs?

Bronchitis Lung Disease:What Are the Early Warning Signs of Lung Cancer?

Lung cancer has many symptoms however some of the earliest signs can be mistaken for tasteless daily illnesses. Many of the symptoms of lung cancer do not show up until the cancer is in a later stage. Some of the early warning signs can include:

o Persistent Cough
o Recurrent Bronchitis or Pneumonia
o Loss of Appetite, Weight Loss
o Chest Pain

Some of the supplementary symptoms of Lung Cancer are listed below. While having any of these symptoms does not mean you have cancer, a Dr. Should be consulted if you are suffering from any of the following:

o Fever without a known reason
o Abnormal Chest X-ray
o Coughing Up Blood
o Hoarseness
o lasting Shortness of Breath

If you are suffering from any or several of these symptoms and you are a current or old smoker, you should palpate your doctor and agenda an appointment to have an examination. There are tests that can be done to settle the cause of your symptoms and these tests can either diagnose or rule out lung cancer. Some of the tests available comprise a blood count test, X-ray as well as bone scan or sputum exam.

Conclusion

If you are a smoker and are implicated about any of the symptoms you are experiencing remember the sooner you are diagnosed the better. Cancer can spread very rapidly and by starting treatments as soon as potential you can improve your opportunity of survival.

Pathophysiology of Copd

Bronchitis Lung Disease:

Copd, or continuing obstructive pulmonary disease, is a progressive inflammatory disease connecting the airways, lung parenchyma, and vasculature. It causes the damage and remodeling of the airways and lung tissue. Proper functioning of lungs is rejected continuously by Copd. Over a period of time, these changes supervene in more severe conditions such as pulmonary hypertension and right heart failure. The exact pathophysiology of Copd is unidentified.

The inflammatory process is a driving aspect in the pathophysiology of Copd. recent verification suggests that the inflammatory response results in a estimate of effects, including an arrival of inflammatory cells such as macrophages, neutrophils and lymphocytes. Thickened airways and structural changes such as increased level muscle and fibrosis may also be manifested. Cigarette smoking causes an inflammatory response in the lungs. This response does not cease with the dismissal of the stimulus, but progresses for an unlimited period of time. Copd is a subset of obstructive lung diseases that includes cystic fibrosis, bronchiectasis and asthma. Degeneration and destruction of the lung and supporting tissue are characteristic of Copd. These processes supervene in emphysema, continuing bronchitis, or both. Emphysema begins with a small airway disease and progresses to alveolar destruction, with a predominance of small airway narrowing and mucous gland hyperplasia.

The pathophysiology of Copd is not entirely understood. continuing inflammation of the cells lining the bronchial tree plays a major role. Smoking and, seldom, other inhaled irritants, perpetuates an ongoing inflammatory response that results in airway narrowing and hyperactivity. Airways come to be edematous, immoderate mucus output occurs and cilia function weakly. Patients face addition strangeness clearing secretions with disease progression. Accordingly, they institute a continuing productive cough, wheezing and dyspnea.

Bronchitis Lung Disease:Pathophysiology of Copd

The basic pathophysiologic process in Copd consists of increased resistance to airflow, loss of elastic recoil and decreased expiratory flow rate. The alveolar walls oftentimes break because of the increased resistance of air flows. The hyper inflated lungs flatten the curvature of the diaphragm and expand the rib cage. The altered configuration of the chest cavity places the respiratory muscles, including the diaphragm, at a mechanical disadvantage and impairs their force-generating capacity. Consequently, the metabolic work of breathing increases, and the sensation of dyspnea heightens.

Causes and Effects of Anoxia

Bronchitis Lung Disease:

Below I have listed five causes of anoxia:

Obstruction to the air passages, for example in strangulation, smothering, pressure by haematoma, or any pressure from exterior the womb.

Lung conditions which prevents the air sacs filling with air, such as pneumonia, where they are filled with exudate, pulmonary oedema, or a collapsed lung.

Bronchitis Lung Disease:Causes and Effects of Anoxia

Damage to the respiratory centre in the brain, or to the nerves supplying the muscles of respiration. This may be caused by a stroke, head injuries, barbiturate or morphine overdose, electric shock, tetanus, and in babies prolonged labour or any brain damage colse to the time of birth.

Poor oxygenation of the blood. This occurs in lasting bronchitis with emphysema, and with congenital defects of the heart in children, because not enough blood reaches the lungs owing to the mechanical defect. It also occurs in carbon monoxide poisoning, because carbon monoxide combines with haemoglobin and prevents it from carrying oxygen, and at high altitudes if oxygen equipment is not carried.

Haemorrhage. Because of the loss of red blood cells, there is too petite haemoglobin to carry enough oxygen. Severe anaemia may also cause anoxia for this reason.

There are many effects on the body that can be caused by anoxia. The brain is very sensitive to lack of oxygen. Sudden anoxia causes unconsciousness, and if the anoxia is complete and lasts more than two minutes, permanent brain damage can be caused, and if much longer, death.

Prolonged anoxia at the time of birth is a cause of reasoning handicap. More lasting anoxia, as in congestive heart failure causes reasoning blurring and irritability. A child with congenital heart disease who is anoxic has stunted increase and perhaps somewhat arrested reasoning development.

The kidneys are also damaged by anoxia. If the anoxia is acute, the patient may invent anuria and acute renal failure. If it is more chronic, there may be lasting renal failure.

The usual signs of anoxia is that the patient becomes blue, especially at the extremities and colse to the mouth. This is the main sign to look out for.
