Uncontrolled growth of cells in lungs is mainly known as lung cancer. It can be start in one or both of the lungs. The abnormal cells can’t develop into healthy tissues, and they break frequently and form tumors in human lungs. Lung cancer is the most common cancer found in human body. Most of the deaths are happen in world due to the lung cancer. In other words, Cancer that develops in the form of tissues in lung is known as lung cancer. Lung carcinoma is another name of lung cancer, this tissues or cells growth can spread in other part of the body by the process of metastasis. Lungs play a very important part in human life, as lungs are present in chest of the humans and intake oxygen when humans inhale and release the carbon dioxide. As lung cancer is diagnosed in later age, so only 10% of the patients are cured.
Some of the symptoms for lung cancer are:
Cough: If a cough is not go away in one or two week, then it is a symptom of lung cancer. Cough can be dry or mucus. Then the doctor will ask you to get the x-ray or other test done.
Cough changes: You have to be notice that you have a change of cough, mainly when you smoke. If you having cough for long time and coughing very frequently, cough is deeper and sounds hoarse, or blood comes out with the cough, then it may be major symptom of lung cancer and needs to be checked with doctor.
Pain in chest: Pain in chest, shoulder is also the symptoms of lung cancer. You should consult with the doctor if having a pain in chest, shoulder.
Wheezing: It is the most common symptom found in lung cancer patients, especially when diagnose late, or in next stage. Major lung cancer patients experience symptoms like cough, shortness of breath, wheezing etc.
Hoarseness: Hoarseness is the word refers to weakening of the voice. Hoarseness is the common symptom of lung cancer. Voice originates from the voice box, or larynx, present in the throat. The larynx becomes inflamed, due to overusing of voice or due to infections. Hoarseness is also a symptom of larynx cancer, which can be developed by chewing of tobacco.
Sudden weight loss: A sudden weight loss is also a sign of lung or other cancer. If cancer is already developed in body, sudden weight loss is expected due to cancer tissue using energy.
Pain in Bone: If lung cancer has spread towards the bone then patient may suffer from back or it other parts of the body. This pain increased in night while lied on bed. Lung cancer may also link with arms, shoulder, and neck pain.
Headache: Headache is also a sign of lung cancer if cancer has increased to the brain. Whereas, there is a very low chances of headache due to the lung cancer.
Types of Lung Cancer
There are two types of lung cancer. First is Small cell lung cancer (SCLC), it also refers to oat cell cancer. About 15% cancer patients having small cell lung cancer. The main cause of small cell lung cancer is chewing of tobacco. Approximately 95% of small cell lung cancer patients having the smoking/chewing of tobacco history. Also those people who are living with the smokers having 30-40% chances of developing cancers in their body. Small cell lung cancer is a fast growing/spreading cancer; it spreads in body very quickly. Main symptoms of small cell lung cancer are bloody sputum, pain in chest, loss in appetite, wheezing, swelling on face, fever, difficulty in swallowing.
Second lung cancer is Non small cell lung cancer (NSCLC). NSCLC is the most common lung cancer. Approximately 70-80% of victims having Non small cell lung cancer. There are three types of NSCLC. First is Aden carcinomas, is the most common type of non small cell lung cancer. Aden carcinomas are found in smokers and in non smokers, especially in women. Most of the adenocarcinomas is develop in outer part of the lungs and they also spread to the lymph nodes and also develops in multiple locations in lung. Its increase very frequently in body especially in women. Second type of non small cell lung cancer is Squalors cell carcinomas and also known as epidermis carcinoma. It develops when abnormal cells multiply in large number and form a tumor. They normally spread to the other parts of the body due to the flow of blood and lymph through the lungs. These lymph and blood carrying the cancer cells to the chest wall, neck and other areas nearby the lungs. The third type of Non small cell lung cancer is Large cell carcinomas. This is very rare type of lung cancer found in cancer patients. Only 10-15% of lung cancer patients may be suffered from large cell carcinomas. This can be spread very frequently towards the lymph nodes.
If someone finds some symptoms of lung cancers so the doctor’s advice for some tests likes imaging tests, these are the x-ray of the lungs. Or a CT scans which is better than the x-ray as find the smallest lesion in lungs.
Sputum cytology: If someone is suffering from cough from 2-3 weeks and also throws sputum, can check with the help of microscope and may find the presence of lung cancer.
Tissue sample(biopsy): Doctors examine abnormal areas of your lungs with the help of lighted tube that enters in your throat towards to the lungs, which is called mediastinoscopy, in which an incision is made in the neck and with the help of surgical tools, doctors takes the sample of tissues from lymph nodes.
If a cough is not go away in one or two week, then it is a symptom of lung cancer: In surgery, the surgeon removes the lung cancer, procedure of surgery contains, wedge resection, in which surgeon removes small part of lung that having the tumor. Segmental resection, to remove large part of the
lungs, lobotomy, to remove the entire lobe of a lung and pneumonectomy, to remove the lung.
Surgery is the option when the cancer is present in lungs only, if there is a large lung cancer, then doctor recommend radiotherapy or chemotherapy to reduce the size of cancer. If doctor finds a risk that some cancers cells are left in body after the surgery, then doctors again suggest the radiotherapy or chemotherapy.
Radiation Therapy: In this therapy, high energy beams are used to destroy the cancer cells. It is used when the cancer tumor is large and cannot be removed. After surgery, radiation is also used to destroy left cells or before surgery, radiation may be use to reduce the size of tumor so it can be operate easily.
Chemotherapy: Chemotherapy is a treatment with drugs/pills insert in vein or from mouth and enter in bloodstream and cover the complete body, this is very useful therapy for operating cancer in any part of the body. Whereas chemotherapy is not recommended for patients not having good health.
