What is lung cancer – is a disease caused to a growth of tumor present inside the lungs due to the uncontrolled cell growth in tissues of the lung.docx

# data[].attributes.body
Lung Cancer- It is a type of cancer that begins in the lungs(two spongy organs that help for inhalation and exhalation)

Positive correlation between smoking cigarettes and lung cancer

The cells in the lungs are damaged when a smoker inhales the smokes as its full of carcinogens.

At early stages the body may be able to repair the damaged cells but if smoking continues, more normal cells become damaged, then cells act abnormally and cancer develops.

Types

1. Small cell lung cancer- usually occurs in heavy smokers

2. Non-small cell lung cancer

Causes of lung cancer:

Smoking

Exposure to smoke, radon gas, asbestos and other carcinogens.

Genetics

Complications/Symptoms:

Breathless

Coughing blood

Pain

Fluid accumulated in the pleural cavity

Metastasis- spreading of cancer to other parts of the body

Prevention

Don’t smoke/Quit smoking

Avoid passive smoke, radon and carcinogens

Have fruits and veggies

Exercise

Lung Cancer
Lungs are spongy organs where exchange of gases take place.
Lung cancer is uncontrolled growth of abnormal cells, usually in air passages, in either of the lung.
As tumours grow, they undermine their lungs ability to provide efficient exchange of gases.

Causes
-Carcinogens, which are are cancer causing substances, damage the lung tissue causing it to act abnormally

Types of lung cancer
-Malignant tumours: these spread through the other part of the body through blood stream and lymphatic system.

-Primary lung cancer: originates in the lung whereas secondary lung cancer starts somewhere in the body and metastasizes and reaches the lungs.

Symptoms
- Shortness of breath
- Chest pain
- Hoarseness of voice
- On-going cough
- Losing weight

Prevention
- Do not smoke
- Avoid carcinogens at work

Emphysema
It is an irreversible lung condition in which the alveoli lose their ability to contract after expanding, this leads them to be filled with air thus leading to burst. This makes breathing difficult and O2 in blood stream decreases.

Causes
Smoking
Passive smoking
Air pollution
Marijuana smoking

Symptoms (seen only after 50% damage)
- Coughing
- Chest tightness
- Wheezing
- Shortness of breath
- Excessive mucus production

Stages
- At risk- Normal breathing - ongoing cough and more mucus produces
- Mild/ early- breathing with mild air flow blockage, ongoing cough , more mucus production.
- Moderate- Medical attention is needed, decline in airflow, shortness of breath during activities.
- Severe - Breathing test show severe limited air flow.

Emphysema is a disease which affects the alveoli in the lungs. alveoli are tiny air sacks responsible for exchange of gases (O2 and CO2 in and out of the blood stream.) in the condition of emphysema the shape of the alveoli deforms from a healthy flattened disk to irregularly shaped strcutures with gaping holes.
Causes of emphysema include:
ciagrette smoke
marijuana smoke
fumes of coal dust
air pollution
Symptoms of emphysema:
shortness of breath
Prevention:
Radon detectors
reduce smoking
healthy diet
regular exercises
Effects of emhysema
Incurable inefficiency of lungs.
Lung cancer:
Uncontrolllable growth of cells (tumour) and the lining of lungs get damaged due to excessive smoking, radon exposure and carcinogens. Small cell lung cancer is normally what heavy smokers suffer from, wheras, small cell lung cancer can affect non-smokers (second hand smoking) as well. metastisis is a condition where the tiumour spreads because of the nutrition required for the cancerous cells to grow. affected organs increase from lungs to adrenal glands, brains, bones, and liver. . Pleural effusion is also a severe condition when fluid surrounds the lung and causes it to collapse . Symptoms include: Shortness of breath, chest and bone pain, weight loss without trying, headaches. You can prevent these diseases by not smoking and incorporating healthy habits in your daily routine. LUNG CANCER  EMPHYSEMA

lung cancer
a type off a cancer that begins in the lungs. lung cancer its the lading cause of cancer deaths in both men and women. the risks increases with prolonged used. lung cancer claims more lives each year than do colon, prostate ovarian and breasts cancer combined.
_ there are 2 types of a cancers-

Small cell lung cancer occurs almost exclusively in heavy smokers and is less common than non-small cell lung cancer( related to all types of smoking )

Non-small cell lung cancer is for several types of lung cancers that behave in a similar way. Non-small cell lung cancers include squamous cell carcinoma, adenocarcinoma and large cell carcinoma.

Signs and symptoms of lung cancer may include:

A new cough that doesn't go away

Coughing up blood, even a small amount

Shortness of breath

Chest pain

Hoarseness

Losing weight without trying

Bone pain

Headache

the complications are -
1) shortness of breath
2)coughing up blood
3)pain
4)fluid in chest
5)cancer spreads in all other parts of body

Prevention -
stop smoking
install radon detectors
eat a healthy diet
avoid carcinogens
exercise

Emphysema is a disease which cause the avioli in the lungs to looses their elasticity and hence the ability to contact after expanding .  Due to this air gets trapped in them, and causing pressure to build up and eventually leading to them bursting

most comman causes of emphasema are
a. smoking(all forms second hand, marijuana ect.
b. air pollution
c. chemical fumes
d. alpha and antitrypsin deficiency
e. genectic conditions

as you age your chance for getting emphysema.  individuals over 40 are at the highest risk of getting this disease.

Symptoms
a. coughing
tigh chest
shortness of breath
excesive mucuse production
wheezing
poor apetite
los of weight

complications
1. holes in lungs due to bursting of the alvioli
2. infection due to excess mucus
3. collapsed lungs due holes in lungs
4. heart problems as the heart has to work over time as there is a reduction in the quantity of air that is taken into the body
5. can lead to lung cancer
6.  reduces standard of living

Note: copd (chronic obstructive pulamary disorder) a disease caused by damage to the lining of the repitiry system (
