Lung cancer appears as a result of uncontrolled growth of ''bad'' cells in the lungs. In its turn, it leads to Tumors and worse lungs’ functioning. There appear problems with blood circulation and respiration. If untreated lung cancer can be fatal.
There are known 2 types of lung cancer: small and non-small lung carcinoma. Each type is treated differently.
The main signs of lung cancer include:
- Recurring respiratory infections
- Trouble breathing
- Difficulty swallowing
- Chest pain, cough, coughing up blood
- Fatigue, weight loss and loss of appetite
Sometimes lung cancer spreads to adjacent tissue and attacks the nervous system. In this case there can appear additional symptoms like seizures, blurred vision, tingling, loss of sensation in certain parts, and sometimes numbness.
Lung Cancer Diagnosis
When it comes to lung cancer, in about 25% of cases there are no any evident signs or symptoms of it. If there is a trouble with breathing or respiration, it is important to see a physician. Being done at an early stage, lung cancer can be successfully cured. The diagnosis can be confirmed with 3 methods: x-ray, CT scan, or bronchoscopy. X-ray can detect enlarged lymph nodes in the chest. CT scan will be used if something abnormal is found with the X-ray. The bronchoscopy will be needed to make biopsy of the lung cells. Besides these 3 methods, the doctor can also ask you to pass MRI imaging to check the possibility of cancer.
Lung Cancer Treatment
Lung cancer treatment includes surgery to remove the tissue affected by cancer. Other successful therapies used in lung treatment are chemotherapy and radiation. Chemotherapy stands for using medicines that destroy cancer cells. It is used to regulate and prevent the growth of cancer cells, being effective in case of small cell lung cancer.
If a patient doesn't want to undergo surgery, he can try radiation therapy where radiation is used to destroy cancer cells. This therapy is very popular, as it allows destroying both small and non-small cell lung carcinoma. In certain cases both radiation therapy and chemotherapy can be very effective after surgery, as these prevent the re-growth of cancer cells. Although any prognosis about cancer is usually poor, the early detection of it significantly increases chances of being completely cured.
