2b – health – Lung Cancer
Lung cancer incidence rate is a steady increase.
It considered the leading cause of death among
cancers in men and third among women.
Of about – 7.6 million deaths annually from cancer,
approximately – 1.3 of it caused by lung cancer.
Most patients with lung cancer are diagnosed at an
advanced stage of their illness and only
about – 15% of all lung cancer patients cured.
Most patients diagnosed with advanced
disease or simplified, when the tumor can
not be more surgical pillow.
Standard treatment at this point of the disease,
improves quality of life and make them longer.

There are two types of histology’s lung cancer:
- Lung cancer, which is not small cell type
(NSCLC non-small cell lung cancer)
which is 85% – 90% of all cases. - Small cell lung cancer (SCLC) approximately
7% -15% of cases.
Epidemiology primary cause of lung cancer is smoking.
70-75 cases out of 100 instances of lung cancer caused by smoking.
Passive smoking increases the risk of lung cancer.
The risk of developing lung cancer associated with smoking and for the total amount of cigarettes consumed.
For example, 40 years of smoking Double the risk of lung cancer compared with 30 years of smoking.
The risk doubled if smoking began before the age of 15.
Symptoms – cough, shortness of breath, phlegm blood, chest pain recurring lung infections.
Complete resection of lung cancer is the most likely cure.
25% -30% of patients are diagnosed at a point that allows surgical resection.
Locally advanced disease standard treatment is a combination of chemical treatment with radiation therapy
and simplified disease chemical treatment combines 2 medicines, One from the new-generation and one which is old-fashioned.
Old-fashioned remedies are: Carboplatin, Cisplatin.
New generation remedies are: Gemcitabine, Taxol, Taxotere and Navelbine.
It should be noted that the treatment of lung cancer is advanced in recent years thanks to new drugs
such as antibodies and target biological treatments,
some of which have been approved for the treatment, some are being tested on clinical trials.
Causes For Lung Cancer
Cigarette smoking is known to cause the vast majority of lung cancer.
Risk of developing the disease rises with increasing number of
cigarette smoked, and as smoking was started at a young age.
With filter cigarettes containing low tar quantity, can slightly reduce
the risk, but of course much higher risk than someone who
does not smoke, even in this case.
Someone who stopped smoking, significantly reduces his risk of lung cancer.
The risk is decreasing as time passes from time to quit smoking.
People who work with asbestos also or people with asbestos poisoning,
have higher risk of getting lung cancer.
Symptoms for early detection of Lung Cancer
Most people usually tend to see a doctor after a while they feel pain.
Those who have lung cancer characterized by the following symptoms:
Cough, short breath, beep while breathing, chest pain (especially when you cough),
outgoing mucus with blood, loss of appetite, weight loss, pneumonia not responding medication.
Diagnostic Process for Lung cancer
Diagnosis by X-ray is the first stage if the patient reports symptoms indicative of the disease.
Examination can reveal visible signs.
If there are no visible signs on the X-ray results but suspicion still exists
tests of lung biopsy is often necessary to locate the tumor and its kind.
Treatment Types for Lung Cancer
Type of treatment for lung cancer depends on the type of the tumor,
spread levels and general health condition of the patient.
Currently acceptable treatments are surgery, chemotherapy and radiation.
- Surgery
Surgery is possible treatment if the lung cancer type is NSCLC, and limited only if the tumor is found only in the lung and not spread to other parts of the body.
In addition, it’s important that the patient will have enough independent breath tools to be possible to perform the surgery.
Types of surgery’s are between remove one lobe, two lobes or removal of all lung. - Chemotherapy
With SCLC type of lung cancer, chemotherapy is the tumor primary treatment.
The main goal of such a treatment is to destroy the cancer cells of the patient.
The main problem of such a treatment is that it finds it difficult to distinguish between normal cells and cancer cells,
thats why often also destroys healthy cells completely, which can cause many side effects. - Radiation
Radiation therapy is also called radiotherapy.
During radiation therapy the patient receives high-intensity radiation to the tumor to destroy infected cells.
The treatment itself is local and only affects a local area you radiate.
Sometimes the patient receiving radiation therapy before surgery to minimize the size of the tumor.
Sometimes the patient receiv radiation therapy after surgery to destroy malignant cells remain after operation.
Treatment options for lung cancer include :
1. Chemotherapy is an anti cancer drugs are given to stop cancer cells from multiplying. This treatment is most effective for small cell carcinoma.
2. Surgery to remove the affected part of the lung or an entire lung. This offers the best chance of cure if the cancer has not spread beyond the lungs.
3. Radiotherapy use of x-rays to target and kill cancer cells. It may be used against some early stage lung cancers and to stop cancer in the lymph nodes from spreading further.
4. Targeted therapy is use of small molecules, often in tablet form that may be used after chemotherapy.
5. Clinical trials is a participation in a clinical trial that investigates the safety and effectiveness of novel drugs may be offered.
