Overview

Lung cancer is a type of cancer that begins in the lungs. It is one of the most common types of cancer worldwide and is the leading cause of cancer-related deaths. There are two main types of lung cancer: non-small cell lung cancer (NSCLC) and small cell lung cancer (SCLC).

Non-small cell lung cancer is the most common type

Accounting for about 85% of all cases. It includes several subtypes, such as adenocarcinoma, squamous cell carcinoma, and adeno squamous carcinoma. Small cell lung cancer is less common but tends to grow and spread more quickly than NSCLC.

The most common cause of lung cancer is smoking

With smokers being at a much higher risk than non-smokers. However, non-smokers can also develop lung cancer due to factors such as exposure to secondhand smoke, radon gas, asbestos, and air pollution.

Symptoms of lung cancer

Can vary but may include a persistent cough, coughing up blood, chest pain, shortness of breath, wheezing, hoarseness, weight loss, and fatigue. Unfortunately, symptoms often do not appear until the disease is advanced, making early detection challenging.

Diagnosis of lung cancer

usually involves imaging tests such as chest X-rays, CT scans, and PET scans, as well as biopsies to confirm the presence of cancer cells. Once diagnosed, the stage of the cancer is determined to guide treatment decisions

Prevention of lung cancer

Involves avoiding tobacco smoke, both first-hand and secondhand, as well as other known risk factors such as radon and asbestos.

Screening for lung cancer

With low-dose CT scans is recommended for certain high-risk individuals, such as current or former smokers.

Prognosis for lung cancer

Varies depending on the type and stage of the cancer, as well as the overall health of the patient.
Early detection of lung cancer treatment can greatly improve outcomes, but overall survival rates for lung cancer remain relatively low compared to other types of cancer. Lung cancer treatment options depend on several factors, including the type and stage of the cancer, as well as the overall health and preferences of the patient.

Treatment modalities for Lung cancer Treatment in Chennai

Surgery

Surgery is often recommended for early-stage non-small cell lung cancer that has not spread beyond the lungs. The goal of surgery is to remove the tumor along with a margin of healthy tissue. Types of surgery for lung cancer include wedge resection, segmental resection, lobectomy, and pneumonectomy.

Chemotherapy

Chemotherapy uses drugs to kill cancer cells or stop their growth. It is often used in combination with surgery or radiation therapy for lung cancer. Chemotherapy may be given before surgery (neoadjuvant therapy) to shrink the tumor, or after surgery (adjuvant therapy) to kill any remaining cancer cells.In advanced stage setting Chemotherapy is administered with a paliative intent .
Radiation Therapy For Cancer

Radiation therapy

Radiation therapy uses high-energy beams to target and kill cancer cells. It can be used as a primary treatment for early-stage lung cancer or in combination with surgery or chemotherapy for more advanced stages. Radiation therapy may also be used to relieve symptoms in patients with advanced lung cancer. Radiotherapy techniques for lung cancer include IGRT, VMAT, SRT, etc .

Systemic Therapy For Cancer

Targeted therapy

Targeted therapy drugs target specific genetic mutations in lung cancer cells that help them grow and spread. These drugs are most commonly used in the treatment of advanced non-small cell lung cancer. Targeted therapy is often more effective and less toxic than traditional chemotherapy.Drugs for lung cancer treatment include Gefitinib, osimertinib, Lorlatinib, Alectinib, Selpercatinib etc.

Immunotherapy

Immunotherapy works by boosting the body’s immune system to help it recognize and attack cancer cells. It has been a major advance in the treatment of certain types of lung cancer, particularly non-small cell lung cancer. Immunotherapy drugs called checkpoint inhibitors have shown promising results in some patients. Immunotherapy medications in Lung cancer include Nivolumab, Pembrolizumab,  Atezolizumab etc.

Combination therapy

In some cases, a combination of different lung cancer treatment modalities may be used to effectively treat lung cancer. For example, a patient may receive chemotherapy and radiation therapy together, or a combination of targeted therapy and chemotherapy.

Palliative care

Palliative care focuses on improving the quality of life for patients with advanced lung cancer. It can help manage symptoms such as pain, shortness of breath, and fatigue, as well as provide emotional and spiritual support for patients and their families.
