Lung cancer is one of the most common and deadly cancers worldwide. It occurs when cells in the lungs grow uncontrollably, forming tumors. Lung cancer can either begin in the lungs (primary lung cancer) or spread to the lungs from other parts of the body (secondary or metastatic cancer). In this blog, we will explore what lung cancer is, its causes, symptoms, prevention strategies, and the treatment options available. Additionally, we will highlight why Sahyadri Hospitals is an excellent choice for lung cancer diagnosis and treatment.
What Is Lung Cancer?
Lung cancer is a disease where abnormal cells in the lungs grow and divide uncontrollably. There are two main types of lung cancer:
Non-small cell lung cancer (NSCLC): The most common form, making up about 85% of all lung cancer cases. It includes adenocarcinoma, squamous cell carcinoma, and large cell carcinoma.
Small cell lung cancer (SCLC): Less common but more aggressive. This form of cancer tends to spread more rapidly and is often diagnosed at an advanced stage.
Both types of lung cancer can cause significant health problems, including difficulty breathing, coughing, and chest pain. It is essential to understand the causes, risk factors, symptoms, and treatment options to combat this condition effectively.
Symptoms Of Lung Cancer
The symptoms of lung cancer can vary depending on the type and stage of cancer. Early-stage lung cancer may not cause noticeable symptoms, which is why it is often detected late. Some of the common signs and symptoms include:
Persistent cough: A new or changing cough that does not go away.
Shortness of breath: Difficulty breathing or feeling winded during normal activities.
Chest pain: A dull or sharp pain in the chest, often worsened by deep breathing or coughing.
Coughing up blood: A sign of advanced disease that may indicate bleeding from the lungs.
Fatigue: A constant feeling of tiredness that does not improve with rest.
Wheezing: A high-pitched sound while breathing due to narrowed airways.
Weight loss and loss of appetite: Unexplained weight loss is common in many cancer patients.
If you experience any of these symptoms, it’s important to consult a healthcare professional for further evaluation. Early detection of lung cancer significantly improves the chances of successful treatment.
Causes And Risk Factors For Lung Cancer
Lung cancer can occur for a variety of reasons, with the most significant risk factor being smoking. However, non-smokers can also develop lung cancer. The following are some of the common causes and risk factors:
1. Smoking:
Smoking is the leading cause of lung cancer, responsible for approximately 85% of all cases. The harmful chemicals in tobacco smoke damage the cells of the lungs and can lead to cancer over time. Both active smokers and those exposed to secondhand smoke are at an increased risk.
2. Radon Exposure:
Radon is a colorless, odorless gas that naturally occurs from the decay of uranium in soil, rock, and water. Long-term exposure to high levels of radon increases the risk of lung cancer.
3. Asbestos Exposure:
Exposure to asbestos, a group of minerals that were widely used in construction and industrial materials, is linked to a higher risk of lung cancer, especially in those who smoke.
4. Environmental Pollutants:
Air pollution, including exposure to diesel exhaust fumes and other toxic chemicals, can increase the risk of lung cancer.
5. Family History:
A family history of lung cancer can increase the risk, suggesting that genetic factors may play a role in the development of the disease.
6. Previous Radiation Therapy:
People who have had radiation therapy to the chest, particularly for other cancers, are at an increased risk of developing lung cancer.
Prevention Of Lung Cancer
While it is not always possible to prevent lung cancer, certain lifestyle changes can help reduce the risk:
1. Quit Smoking:
The most effective way to prevent lung cancer is to avoid smoking or to quit if you are a smoker. The risk of lung cancer decreases significantly after quitting, even for those who have smoked for years.
2. Avoid Secondhand Smoke:
Staying away from environments with secondhand smoke can lower your risk, especially for non-smokers.
3. Test for Radon:
If you live in an area with high radon exposure, consider having your home tested for radon and taking steps to reduce its levels.
4. Protect Yourself from Occupational Hazards:
If you work in an industry that involves exposure to asbestos, chemicals, or other carcinogens, take protective measures to reduce exposure, such as wearing protective gear and following safety protocols.
5. Maintain a Healthy Lifestyle:
Eating a balanced diet, exercising regularly, and avoiding excessive alcohol use can support overall lung health and reduce the risk of lung cancer.
Treatment Options For Lung Cancer
Treatment for lung cancer depends on the type, stage, and location of the cancer, as well as the patient’s overall health. Some of the main treatment options include:
1. Surgery:
Surgery is commonly used for early-stage lung cancer. The procedure involves removing the tumor and some surrounding tissue. In some cases, the entire lung may need to be removed (pneumonectomy).
2. Chemotherapy:
Chemotherapy uses drugs to kill cancer cells or stop their growth. It is often used for advanced lung cancer or after surgery to remove any remaining cancer cells.
3. Radiation Therapy:
Radiation uses high-energy rays to destroy cancer cells. It is often used when surgery is not an option, or to shrink tumors before surgery.
4. Targeted Therapy:
Targeted therapy targets specific molecules involved in the growth of cancer cells. It is commonly used for non-small cell lung cancer (NSCLC) that has specific genetic mutations.
5. Immunotherapy:
Immunotherapy boosts the body’s immune system to recognize and attack cancer cells. This treatment is often used for advanced-stage lung cancer, particularly small cell lung cancer (SCLC).

FAQ’s
What are the early signs of lung cancer?
Early lung cancer may not show any symptoms, but when they do appear, they may include persistent cough, chest pain, coughing up blood, shortness of breath, and unexplained weight loss.
Can lung cancer be prevented?
While not all lung cancer cases can be prevented, quitting smoking, avoiding secondhand smoke, testing for radon in homes, and reducing exposure to occupational hazards can significantly reduce the risk.
How is lung cancer diagnosed?
Lung cancer is typically diagnosed through imaging tests like X-rays, CT scans, and PET scans, followed by a biopsy to confirm the presence of cancer cells.
What is the survival rate for lung cancer? The survival rate for lung cancer depends on the stage at which it is diagnosed. Early-stage detection and treatment significantly improve survival rates, but the overall 5-year survival rate for all stages is about 19%.
Can lung cancer affect non-smokers?
Yes, non-smokers can develop lung cancer. Other risk factors include exposure to radon, asbestos, air pollution, and a family history of lung cancer.
What are the side effects of chemotherapy for lung cancer?
Common side effects of chemotherapy include fatigue, hair loss, nausea, vomiting, and an increased risk of infections due to a weakened immune system. However, side effects vary from person to person.
What is the difference between small cell and non-small cell lung cancer?
Non-small cell lung cancer (NSCLC) is the most common form and grows more slowly, while small cell lung cancer (SCLC) is rarer but tends to spread more quickly and is usually diagnosed at an advanced stage.
