Lung Cancer – Causes, Symptoms and Treatment
Lung cancer is a disease of uncontrolled cell growth in tissues of the lung. This growth may lead to metastasis, invasion of adjacent tissue and infiltration beyond the lungs. The vast majority of primary lung cancers are carcinomas of the lung, derived from epithelial cells. Lung cancer, the most common cause of cancer-related death in men and the second most common in women,[1][2] is responsible for 1.3 million deaths worldwide annually.
What causes lung cancer?
Smoking
The incidence of lung cancer is strongly correlated with cigarette smoking, with about 90% of lung cancers arising as a result of tobacco use. The risk of lung cancer increases with the number of cigarettes smoked over time; doctors refer to this risk in terms of pack-years of smoking history (the number of packs of cigarettes smoked per day multiplied by the number of years smoked).
Lung cancer most commonly begins in the cells that line your lungs. Smoking causes the majority of lung cancers — both in smokers and in people exposed to secondhand smoke. But lung cancer also occurs in people who never smoked. In these cases, there may be no clear cause of lung cancer. Doctors have identified factors that may increase the risk.
Cancer that originates from lung cells is called a primary lung cancer. Primary lung cancer can start in the airways that branch off the trachea to supply the lungs (the bronchi) or in the small air sacs of the lung (the alveoli). Cancer may also spread (metastasize) to the lung from other parts of the body (most commonly from the breasts, colon, prostate, kidneys, thyroid gland, stomach, cervix, rectum, testes, bone, or skin).
Lung Cancer Symptoms
Lung cancer symptoms are commonly not experienced until the disease had advanced, sometimes delaying diagnosis. The symptoms of lung cancer also mimic the symptoms of other benign illnesses.
The most common lung cancer symptoms experienced are :
Onset of wheezing
Recurrent pneumonia or bronchitis
A persistent cough that does not go away
A sign is also an indication that something is not right in the body. But signs are defined as things that can be seen by a doctor, nurse, or other health care professional. Fever, rapid breathing rate, and abnormal breathing sounds heard through a stethoscope may be signs of pneumonia.
Lung Cancer Diagnosis
To help find the cause of symptoms, your doctor will evaluate your medical history, smoking history, exposure to environmental and occupational substances, and family history of cancer. Your doctor also will perform a physical exam and may recommend a chest X-ray and other tests. If lung cancer is suspected, sputum cytology — the microscopic examination of cells obtained from a deep-cough sample of mucus in the lungs — is a simple test that may be useful in detecting lung cancer. To confirm the presence of lung cancer, your doctor must examine tissue.
How can I prevent lung cancer?
The best way to prevent lung cancer is to quit smoking, or to never start in the first place. You should try and avoid being around people who are smoking; and also avoid pipes, cigars, and marijuana. If you live in an area with radon, you should make sure there is adequate ventilation in your basement to get rid of it. Use a detector to make sure the radon levels are low.
Treatment Of Lung Cancer
Many factors must be taken into account to determine the best treatment for an individual diagnosed with lung cancer. The specific type of cell, the location of the lung tumor, the stage of the disease with possible metastasis (spread to other parts of the body), and the general health of the individual must be considered. Various treatment plans may include radiation therapy, chemotherapy, and/or surgery.

Cancer can spread sometimes very quick. I have known numerous cancer patients with lung cancer that it had spread to the brain. There is really no right answer on how fast this can happen. Depends on the individual.
no i doubt u do!
do u have asthsma???
umm it could just be cuz u were out in the cold but if it still hurts tomorrow afternoon then go to the dr.
but i realy really doubt it is cancer!
Lung cancer is awful because by the time you see the signs, it is usually too late to do anything but prolong your life a little bit. At least with most kind of cancers, they are treatable because you can detect them early. It is very difficult to diagnose lung cancer early.
It’s not just cigarettes becasue healthy people who don’t smoke are getting Cancer, Why is it in Canada their is 1 in 2 men and 1 in 3 woman who will be diagnosed with Cancer in your life.
Yes don’t smoke but know they are spending billions to catch it after you get it becasue preventive is obviously not working. We need a Cure..
My aunt had lung cancer and could not travel long distance. It just depends on how strong your grandmother is and if she feel up to it.
I had to watch this for a college assignment!
Verry touching
I have to say i dont know what your going through because i havent gone through it but your an insperation. i cant tell you how sorry i am for you and your family. your family is in my prayers and always will be.
I’m so sorry for you and your family for suffering the loss of your Mom. The love you share is palpable.
flubbberbobb, i highly suggest you reform your comment because that was extremely rude. I hope you believe in a higher power or intelligent designer because if you are that self responsive then obviously you got some issues bro
My father was diagnosed with stage IV lung cancer in February of 2006. March of 2006, less than a month later, he died. He smoked two packs a day, started smoking at 12 years old.
I see stupid kids desiring to smoke, trying to buy cigarettes underage, and think how stupid these kids are. By smoking they show they don’t care for people close to them. Cancer doesn’t just affect the individual, it affects everyone close them.
dude having cancer is so awesome i never have to get a hair cut, plus i had sex with my dog and he got it hes dead now
I understand what you are going through. My Mom was diagnosed with a rare cancer that has no cure. It shuts down ur heart, lungs, and kidneys. It has already shut down her kidneys and its affecting her heart. She has to learn to walk again. I know that things may seem hard but you just got to keep the faith
