Lung Cancer Risk Factors

Lung cancer is a critical condition in which cells grow or develop uncontrollably in the lungs. Lung cancer is one the most common types of cancer. This condition is mostly possessed by smokers, both active and passive.
In the initial stages, there are no signs or symptoms that refer to lung cancer, so that a large number of patients are not getting an early diagnosis. Thus, when detected, the cancer or the growth has spread and is too difficult to be treated. Therefore, it is essential to recognize the symptoms of lung cancer so that the handling can be better and more effective.


A risk factor that can affect a person’s chance of getting a disease such as cancer. Different cancers have diverse hazard factors. Some risk factors, like smoking, can be changed. Yet, having a hazard factor, or even several, does not mean that you will get the disease. And some people who get the disease may have few or no known risk factors.
Several risk factors can make you more likely to develop lung cancer.

Tobacco smoke
The leading risk factor for lung cancer is known as smoking. About 80% of lung cancer deaths are thought to result due to smoking. The risk or hazard for lung cancer among smokers is many times higher than among non-smokers. The more you smoke and the more packs a day you smoke, the greater your risk.
Cigar smoking and pipe smoking are almost same as to cause lung cancer as cigarette smoking. Smoking low-tar or “light” cigarettes expands lung cancer risk as much as regular cigarettes. Smoking menthol cigarettes may expand the risk significantly more since the menthol enables smokers to inhale more deeply.


Exposure to radon
Radon is known as a naturally occurring radioactive gas which results from the breakdown of uranium in soil and rocks. You can’t see, taste, or smell it. Radon is also known as the second leading cause of lung cancer and is the leading cause among non-smokers.

Exposure to asbestos
People who normally work with asbestos (such as in mines, mills, textile plants, place where insulation is used, and shipyards) are several times more likely to die of lung cancer.

Exposure to other cancer-causing agents in the workplace
Lung cancer can also be caused by other carcinogens (cancer-causing agents) found in some workplaces include: uranium, minerals and chemicals such as arsenic, mustard gas, coal products, nickel and chromium compounds etc.

Acute Abdomen Symptoms and Management:

Image
Acute Abdomen Symptoms and Management: The acute abdomen shows a rapid onset of severe life- threatening symptoms includes the sudden, spontaneous, nontraumatic disorder whose chief manifestation is in the abdominal area.  For acute abdomen urgent operation may be necessary. Acute abdomen has a large number of possible causes and so a structured approach is required. If the patient has an acute surgical problem the initial assessment for acute abdomen should attempt that requires immediate and prompt surgical intervention, or urgent medical therapy. Abdominal pain is a common problem. Symptoms and Causes: Vomiting, Haematemesis or melaena, Stool/urine colour, Fainting, dizziness or palpitations, Fever/rigors, Rash or itching, Urinary symptoms, recent weight loss. Some common causes of acute abdomen usually involve a slower rate of bleeding, but with urgent surgery still required, include bleeding gastric ulcer, ruptured ectopic pregnancy, and trauma.  Every pa

Newborn screening for critical congenital heart disease using pulse oximetry

Image
Newborn screening for critical congenital heart disease using pulse oximetry: The most common congenital disorder in newborns is congenital heart disease (CHD). In the first year of life requiring surgery or catheter- based intervention is known as Critical CHD. Normally in case of infants with critical cardiac lesions, the risk of morbidity and mortality increases when there is a delay in diagnosis and timely referral to a tertiary center with expertise in treating these patients. Pulse oximetry:   it is a non-invasive method for monitoring a person's oxygen saturation. The application mode of pulse oximetry includes, a sensor device is placed on a thin part of the patient's body, usually a fingertip or earlobe, or in the case of an infant, across a foot. In this process the device passes two wavelengths of light through the body part to a photodetector.  The changing absorbance at each of the wavelength are measured by this, which allowing it to determine the

Bronchitis (Acute) Symptoms, Causes, Treatment, and Cures:

Image
Bronchitis (Acute) Symptoms, Causes, Treatment, and Cures: An inflammation of the lining of your bronchial tubes is known as Bronchitis. There are two types of bronchitis    1) acute bronchitis, and 2) chronic bronchitis. Acute bronchitis is defined as a cough lasting five or more days also known as a chest cold, the cough may linger for weeks. In some cases people with recurrent acute bronchitis develop chronic bronchitis and a respiratory infection. Chronic bronchitis is known to be lasts for at least 3 months, 2 years in a row. It is defined as a cough that occurs every day with sputum production.   Medical attention is required for chronic bronchitis. Chronic bronchitis is one of the conditions included in chronic obstructive pulmonary disease (COPD). Viral or bacterial infection are the most common way for infection, due to this people become infected with or “get” acute bronchitis.   Irritants like tobacco smoke, air pollution, or chemicals are the other causes.
