Although the 4% of patients with lung cancer without smoking, but few of them have inhaled a significant amount of cigarette smoke (smoke inhaled by smokers). 90% of lung cancer patients have more 10 cigarettes/day in 20 years.

The workers exposed to silica dust are at high risk of lung cancer. This risk will increase many times if the patient smokes. The other occupational exposure related to lung cancer include exposure to steelmaking process, nickel, chromium, and coal gas.

Radiation exposure risk for the cancers including lung cancer. The uranium mine workers, fluorspar and hacmatite may be exposed to radiation due to breathe air containing radon gas.

In addition, the risk of lung cancer is related to the air contaminants. The recent study found lung cancer related gene factor.

The warning signs of early lung cancer

In addition, signs of persistent pain in the chest that does not go away after a long period of time can also be a manifestation of lung cancer that you need to pay attention.

5. hand and finger Pain

Fatigue and pain in the fingers can two early warning signs of lung cancer which many tend to ignore. In most cases, when the skin of the Palms becomes thick and white with wrinkles visibly, then the more likely you are to lung cancer. You should take the examination to determine his condition.

6. blood and Phlegm

Coughing up phlegm and blood is never a good sign, even when the amount of blood that is little or paler. If you encounter this situation, should visit immediately because it can be early warning signs of lung cancer or another serious illness in your body.

7. Change the mood swings

You feel you can easily change the mood quickly, or anger and irritability, followed by fatigue and even depression ... then you are probably at risk for lung cancer or cancer. Because cancer can make you suffer endocrine disorders, stimulates the nerves that control emotion.

8. Frequent infection

Lung cancer can cause infectious condition affecting the respiratory tract and lead to diseases such as bronchitis, or other chronic infections. If you suffer from chronic lung infections, you should take the time to go to lung x-rays to know yourself at risk of lung cancer or not.

9. Shoulder pain

Shoulder pain can happen if a lung tumor development and pressure on the part of the lungs and the nerves at the armpit. This pressure will usually lead to aches, tingling and pain in the shoulders, arms and hands.

This sign is common in men more. That is the condition of the chest to up by unusual cancer cells stimulate the secretion of hormones in an unusual way. However, the sisters also should not ignore this, because most likely it is due to lung cancer cells or th in other parts.

The method of treatment

Surgery to remove the tumor: Most effective when tumors are small and no metastasis. The patient may well to the surgery. 20% of the patients treated by this method. Patients who are surgically retrieved the entire tumor has long life time.

Radiation beam treatment: This method was applied to 35% of patients. The aim is to destroy the tumor when it is still small (typically 6 cm in diameter) and no metastasis. For the large tumor, it reduces the growth of the tumor. this treatment extended the lives of patients but rarely cure.

Treatment with the chemical: Have work well in most patients with lung cancer small cell types and sometimes in the other lung cancers. Recent progress of chemotherapy has significantly reduce these side effects than before.

Treatment support: Only applies to about 1/3 of patients with lung cancer of later stage no treatment was by the above methods, including patient care, treatment of symptoms and relieve pain. Need to have a proper diet, rest, medical care and entertainment sometimes helpful to patients.

In most patients with cancer, the best treatment results when the cancer is detected early and treated promptly. There are now many new treatment methods include putting radioactive isotopes into bronchitis, treated by radiation beam, laser treatment, new chemical drugs, the molecular biology research is underway and has obtained some results.=
