Lung Cancer Symptoms, Prevention and Treatment

What is lung cancer?

Lung cancer, also known as lung carcinoma is a malignant tumor in the lung resulting from an abnormality in the body's cells . The tumor is formed from the uncontrolled division of these cells. Lung cancer spreads throughout the body quickly from the beginning and is the leading cause of cancer death in the United States and around the world for both men and women. There are two types of lung cancer; small cell lung cancer and lung non-small cell cancer.

While lung cancer can be treated, often not diagnosed until it is in an advanced stage.
The survival rate at five years for a lung cancer initial phase is 54%. However, for people diagnosed with advanced lung cancer is considered inoperable, that number is reduced to 4%.

Lung cancer causes

Although smoking long term (snuff ) is the number one risk factor for early lung cancer is not the only cause. There is a small percentage of people who have developed lung cancer without ever having smoked snuff. Living with a smoker increases your risk of developing lung cancer by nearly 30%.

1. Smoking - Cigarette smoke is full of carcinogens. When cigarette smoke that is inhaled these carcinogens and allowing them to enter your body and lungs inhaled. Initially, your body can repair any damage it causes. However, over time, with repeated exposure, the damage done causes more and more damage that causes cells to become abnormal and eventually become cancerous tumors.

2. secondhand smoke -. When you're around someone who is smoking, which is inhaling the same carcinogens as smoking, only in smaller amounts

3. Asbestos - Only 4% of deaths lung cancer are the result of asbestos lung cancer

4. air pollution . -. Air pollution is full of substances that cause cancer, such as smoke, diesel engine exhaust, dust, metals and other hazardous substances

Prevention of lung cancer

Although not 100% effective, the most effective way to prevent lung cancer is to not smoke form, or if you already do, quit. Because the risk of developing lung cancer increases gradually longer and smoking, quit smoking (even after many years of smoking) can greatly reduce the likelihood of developing lung cancer. In basic, general terms this means.

In basic, general terms, this means that the cancer that causes most deaths across the country, not only, but the world as a whole, can be greatly reduced by not smoking.

Symptoms of lung cancer

Symptoms do not usually occur in the early stages of lung cancer. Usually only occur once lung cancer has advanced.

Signs and symptoms of lung cancer include:

* A new cough that will not go away
* Changes in a chronic cough (often referred to as the smokers cough)
* coughing up blood or bloody mucus
* Difficulty breathing
* chest pain
* wheezing
* hoarseness
* unexplained weight loss
* bone pain
headache

Treatment of lung cancer

the treatment for lung cancer may vary depending on several factors including the health of individuals in general, the state of the lung cancer, the type of lung cancer, and other factors. These types of treatment may involve combinations of surgery, chemotherapy, radiation therapy, targeted drug therapy, and in some cases, newer methods are still experimental at this time. In some cases, treatment may not be an option.

The types of surgery extraction of lung cancer

Wedge resection - removal of a small section of lung (including tumor)
lobectomy - removal of a whole lob a lung
segmental resection - removal of a large part of one lung
pneumonectomy - removal of an entire lung
* As with any surgery, there are risks associated with surgeries lung cancer. The most common risks include bleeding, infection and difficulty breathing after surgery.
** The lymph nodes may be removed during surgery so the surgeon can check for signs of cancer.

The chemotherapy to treat lung cancer

Chemotherapy uses drugs intravenously or orally to kill cancer cells. This is usually a combination of drugs administered through a series of treatments that can last up to several months.

Chemotherapy treatments are often used after surgery to ensure that any cancer cells that may remain are killed.

Chemotherapy may be used before surgery in an attempt to shrink the cancer and make it easier to remove.

Radiation therapy to treat lung cancer

Radiation therapy kills cancer cells using energy beams Hihg-fed. The radiation beam is directed towards his lung cancer out of your body or placed inside your body through needles, seeds or catheters.

Radiation therapy may be used after surgery for lung cancer to kill remaining cancer cells.
Radiation therapy can also be used as a first treatment for advanced lung cancers that are inoperable.
Radiation therapy can be used in very small lung cancer rather than surgery.

Targeted drug therapy to treat lung cancer
targeted drug therapy is generally used in combination with chemotherapy ans is a cancer treatment latest. They do not work in all cases of lung cancer and tests will be carried out to determine whether these drugs will help.

Some options targeted therapy drugs include

Afatinib
Bevacizumab
Ceritinib
Crizotinib
Erlotinib
Nivolumab
ramucirumab

the stages of cancer NSCLC

once you have been diagnosed with lung cancer, your oncologist or doctor will perform tests to determine the stage and severity of cancer. The tests most commonly used include X-rays, CT scans, bone scans, PET scans and blood tests.

What do the different stages of lung cancer Mean?

Stage I

stage I lung cancer is an early stage and the cancer is confined to the lung.

Stage II and III

Once the cancer has moved beyond stage I or stage II or III, cancer remains more or less confined the lungs, but it can spread to lymph nodes as well.

Stage IV

Once lung cancer has advanced and reached stage IV, the cancer has spread outside the lungs to other body parts. small cell lung

-Cancer small cell lung Levels

cancer is not as common as small-cell carcinoma. Instead of being broken down into stages, which is divided into two levels:

Stage Limited

During small-cell carcinoma localized stage, the cancer is confined only to nodes and lung lymph.

extensive stage

During stage lung cancer small cell cancer has spread from the lungs to other parts of the body.
