Lung Cancer Symptoms, Signs, Stages, Treatment & Types
Lung cancer or lung carcinoma disease, there is an uncontrolled increase in lung tissues. If this is left untreated, then this growth can spread from adjoining lungs to adjacent cells or other parts of the body, through the process called deflection. Most cancers that originate in the lungs and those called lung primary cancers are carcinomas which emit from epithelial cells.
The main types of lung cancer are small cell lung carcinoma (SCLC), which are also called Oat cell cancers and non-small cell lung carcinoma. The most common symptoms include cough (include bloody cough), weight loss and breathlessness.
Types of lung cancer
- Small Cell Lung Cancer: This type of cancer spreads quickly. It is also called oat cell cancer. About 10%-15% of cancers are of this type.
- Non-Small Cell Lung Cancer: It is one of the most common types of cancer. About 85% of lung cancers are of this type. Subtypes of non-small lung cancer include Squamous cell carcinoma, adenocarcinoma, and large cell carcinoma.
- Lung Carcinoid Tumor:It is also called lung neuroendocrine tumors. About 5% of lung cancers are of this type. They grow slowly and rarely spread.
Causes of Lung Cancer
Many factors are helpful in increasing the risk of lung cancer. Some of these risk factors can be controlled by lifestyle changes, while some other factors such as family history cannot be controlled.
Tobacco use is harmful in any form, whether it is smoking or smokeless (smokeless). Cigarette and bidi smoking are the major risk factors for lung cancer. The use of smokeless tobacco increases the risk of cancer of the lip, mouth, esophagus, digestion, respiratory and chest internal organs. Tobacco causes toxic chemicals to damage the lung cells and they develop abnormally.
Cigarette smoking increases the likelihood of lung cancer in any person by 15 to 30 times. These people are more likely to be filled with lung cancer than those who do not smoke. The increased number of cigarettes increases the likelihood of dying from lung cancer. Every day with the increasing number of smoking and its growing period, this risk is increased.
With exposure to Radon, there is a possibility of some risk of developing cancer, such as lung cancer. Radon, invisible and odorless gas which emerges from breaking uranium and goes in with breath by inhaling. The main source of indoor Radon is soil, building materials, water faucers and cooking natural gas. This gas may accumulate to unsafe levels in homes and buildings. To reduce reden’s accumulation, the basement should be well ventilated.
The history of lung cancer in the first level kinship increases the risk of lung cancer. If there is a cancer in the lungs then the risk of getting it in the other also increases. Those receiving cancer treatment who have received radiation therapy in the chest also have higher risks. If family history is positive then the risk increases even more.
Burning coal inside the house
There is enough evidence to burn the coal in the house to cook or warm up the risk of lung cancer. Poor airy houses, using traditional stoves to cook, increase the level of air pollution, resulting in damage to health.
Chlamydia infection, pneumonia or tuberculosis (TB) etc. can increase the risk of lung cancer. Research indicates that people who have T.B. They have twice the risk of lung cancer.
There is evidence that some dietary factors can be protective for lung cancer and some can increase the risk of lung cancer. Such as low intake of beta carotene-containing foods (like carrots) increases the risk of lung cancer. Vitamin A deficiency increases the likelihood of developing squamous cell carcinoma (lung cancer) in the lungs.
Symptoms of Lung Cancer
Cancers in the lungs cannot be detected in the early stages, because they do not show signs of symptoms at the earliest times. But lung cancer can be avoided when it comes to certain symptoms.
- When you breathe, then if you hear a whistle sound, contact your doctor. This voice points to a variety of health problems, as well as problems related to lungs.
- If you feel the pain of deep or long breathing, then this obstruction can be due to the accumulation of fluid in the chest, which is caused by cancer in the lungs.
- If you feel pain in the back and shoulders along with the chest, take it seriously. This can be due to the transfer of the lascie. Even if you feel healthy, show the doctor.
- If the chest is coughing and the problem persists for more than 2-3 weeks then this infection can occur. In addition, other problems related to cough such as cough or blood in sputum, take it seriously and do checkup.
- Lung cancer may also affect the brain if it has an effect on the brain. In such a situation there is constant headache. Occasionally the tumor is stressed in those veins that transmit blood to the upper part of the body.
- Other symptoms of lung cancer
- respiratory distress
- Pain in chest
- Loss of appetite
Stages of lung cancer
Fatal tumors undergo four main stages of its development, each of which is characterized by signs of expression and treatment. Complete recovery of the patient is possible only in the case of diagnosis of disease at the beginning of its development.
- The survival rate of patients with the first stage of cancer reaches 70%. The most dangerous is the small-cell cancers, which quickly gives metastasis.
- In case of identification, the patient is under immediate remedies (surgical removal of tumors, radiotherapy, taking strong chemotherapy drugs).
- It is difficult to identify the lung cancer of stage 1, because the tumor is still so small that it does not feel itself practically.
- Cough is a dangerous symptom of the onset of disease, initially it appears as weak sweat in the throat, it is gradually intense, in which the scent of rot escapes from floral sputum.
- The lung cancer of the second stage is diagnosed in the presence of more than five centimeter tumors, it appears in the chest with an acute cough with fever, fever and pain.
- The patient may often experience knees, lack of air, and may lose weight faster.
- The stage of cancer 2A means that the tumor itself reaches up to five centimeters in size, in which it is located near the lymph nodes, before it is properly noted in the metastasis nodes.
- The diagnosis of the phase of lung tumor 2b indicates that the tumor has reached a larger size (7 centimeters), but is still spreading to the nearest lymph nodes or reaching nearby tissues.
- Only patients with the second stage of development of lung cancer can survive for up to five years with proper treatment.
- The survival rate is very low – only 36% of the number of cases In case of small cell cancers, this indicator is not more than 18%.
- In the stage of lung cancer 3A, the tumor reaches more than seven centimeters in size, which affects the lymph nodes and sprouts that are closely located in the lungs, thorax, or trachea. In some cases, the tumor is affected close to the heart vessels of the heart.
- The lung cancer of the third stage constantly reminds itself. In order to reduce the condition, firstly, to eliminate severe pain in the chest, the patient is prescribed narcotic drugs, antitussive.
- The main sign of the disease at this point: a severe cough with a significant separation of blood or particles making bronchi lungs.
- In the form of main treatment, chemical preparations are suppressed, and the removal of part of the lungs or whole organs also indicates. Drugs are selected separately on the basis of the form of tumor.
- The survival rate of patients of the third stage of cancer development is extremely low and practically reaches zero.
- Lung cancer of stage 4 is fatal and is not curable.
- This phase means that a malignant tumor has spread to nearby internal organs.
Treatments of lung cancer
Radiotherapy uses high-powered beams to destroy cancer cells.Radiotherapy is either radical or palliative. Radical radiotherapy is used in selected patients with localised tumours which are inoperable, and involves using high doses of radiation to try to destroy the tumour.
Surgery is often recommended when lung cancer is confined to the lungs. Your doctor may recommend that you undergo chemotherapy or radiation first to shrink the tumors.
In recent years several biological therapies have been introduced for some lung cancers. These are a type of drug treatment which work by blocking some of the chemical messages that control growth of the cancer cells, or by helping the immune system to target the cancer.
Chemotherapy uses either intravenous or oral drugs to kill cancer cells. It is usually administered over several weeks, with breaks to allow for recovery time.
