Facts About the Incidence of Lung Cancer

Lung cancer is the 2nd most commonly diagnosed cancer among women and men. It is also the second leading cancer-related cause of death for both genders. These statistics are based on SEER population statistics and are age-adjusted.

The majority of cases are non-small cell lung cancers (NSCLC) which comprise adenocarcinomas and squamous carcinomas. They are a result of smoking.

Smoking

Smoking causes cancerous cells in the lungs to multiply in uncontrolled ways leading to tumors which can make it difficult for a person to breathe. Cancers can also spread to other parts of the body. Other factors can cause lung cancer, but the majority cases are caused by cigarettes smoking or other tobacco use such smoking pipes and chewing tobacco.

Non-small-cell lung cancer (NSCLC) and small-cell lung cancer (SCLC) are the two major Incidence of Lung Cancer kinds of lung cancer. The majority of smokers suffer from a type of NSCLC known as squamous cell carcinoma, whereas a majority of nonsmokers have a type of NSCLC referred as Adenocarcinoma.

Researchers in the 1950s linked smoking cigarettes with lung cancer. This led to international health campaigns that discouraged smoking. But lung cancer continues be a major killer in many countries with the highest rates of mortality and incidence for people who smoke or have had a habit of smoking. Strong Memorial Hospital and its affiliates offer low dose CT scans to screen those who meet the criteria. These scans offer more detailed images of the lungs and air tubes, while utilizing less radiation than chest x rays. This method is 20 percent more likely to identify cancers than chest radiographs.

Smoke exposure to secondhand smoke

Secondhand smoke is the smoky residue left behind by smokers that floats into the air when they exhale or light up. It contains the same harmful chemicals that are found in tobacco smoke that you inhale directly. Certain chemicals cause immediate damage to your lungs and airways. They also increase the risk of heart health and blood vessel issues because they increase the likelihood of blood to clot.

You may be exposed to secondhand smoke in a variety of ways, such as at work, or at social events where people smoke, by being in a home with a smoker or Incidence of Lung Cancer by visiting people who smoke. Inhaling secondhand smoke from tobacco can increase your risk of lung cancer by 30 percent and aggravate respiratory ailments like asthma. It also affects babies who are not yet born, causing preterm birth and low birth weight, and increasing the risk of miscarriage, stillbirth and ectopic pregnancies. Smoking secondhand smoke can make your blood vessels more likely to clot, which increases your risk of heart attack. It can also make a stroke more likely.

Genetics

Certain types of lung cancer are caused by genetic factors. Smokers and non-smokers have a higher risk of developing lung cancer if they have an ancestral history of. Studies have identified several genes that are associated with lung cancer susceptibility, including ERCC6 and the nicotinic Acetycholine receptor gene cluster on chromosome 15q25.1.

Many people inherit defective DNA repair mechanisms, which increase their risk to develop cancer-causing mutations. These mutations can occur in DNA that was either inherited or acquired during life.

These mutations could lead to many different types of cancer that include small cell lung cancer (SCLC) and non-small lung cancer (NSCLC). NSCLC includes Adenocarcinoma, squamous Cell Cancer and large cell carcinoma.

Most genetic changes that increase the risk of developing lung cancer happen throughout the course of a person's entire life. Some may be inherited from parents, and approximately 8% of lung cancer cases run in families. Having a first-degree relative who had lung cancer can also increase the risk of developing the disease. Some gene mutations may cause lung tumors to grow or spread more quickly. Tumor profiling can be a method to determine which genes have been affected in the cancerous lung of a patient. This can aid in determining treatment options.

Environmental factors

Smoking cigarettes is the main cause of lung cancer, but there are many other environmental factors that can contribute to the disease. This includes exposure to chemicals like arsenic, certain organic chemicals, asbestos and radon. This also includes the air pollution caused by dust and fumes. Nonsmokers exposed by secondhand smoking have a higher chance of developing lung cancer.

Radon is an ionizing gas that occurs naturally in the soil and rock However, it can also accumulate in buildings and homes. It can be released in the air by cracks and holes in foundations, walls and sump pumps, drains pipes, vents, and pipes. People who have spent an extended time in homes with high levels of radon are at risk of lung cancer.

Primary prevention is the elimination or reduction of risk factors that affect vulnerable populations. This is accomplished by providing education to the public, supporting health campaigns, and implementing behavioral changes. Media can play an important role in disseminating information about lung cancer to the public.

Signs and symptoms

The symptoms of lung cancer differ according to the type and stage of the cancer. The initial stages of the cancer often do not cause any symptoms, but once the cancer has grown, it can cause breathing problems or back pain due to the pressure of tumors that are located on your spinal cord and ribs. Other signs include a constant cough that gets worse or isn't able to stop or subsides, chest pain, and hoarseness.

The lung is a pair of cone-shaped organs located in the chest. They release carbon dioxide (a waste product produced by the cells) and bring oxygen into the body. The lungs comprise two tubes, called bronchi, which connect to the trachea (windpipe), and a series of small air sacs referred to as alveoli. Non-small cell lung carcinoma, or NSCLC, is a cancer that develops in the lung. Metastatic cancer, or second-line NSCLC is the term used for cancers that begin in other areas before advancing to the lungs.

A health care provider can determine whether you have lung cancer by taking a look at your lungs using a stethoscope, doing an exam and asking about your history of smoking. They may also ask you about any other health concerns that you may have.
