Lung cancer is one of the common cancers in men and women. The lung cancer starts in the main airway, the windpipe, or in the lungs. It develops when there is an uncontrolled growth of abnormal cells inside one or both lungs. These cells grow to form tumors.
There are two major types of lung cancer:
- Non-small cell lung cancer
- Small cell lung cancer
Symptoms of lung cancer
The common early symptom of lung cancer is cough and shortness of the breath. As the tumor develops, these symptoms can become more intense. The other symptoms of lung cancer are as follows:
- Chest or rib pain
- Cough with blood
- Loss of appetite & Unexplained weight loss
- Wheezing & Hoarseness
When lung cancer spread to other parts of the body, it may show some advanced symptoms, which are as follows:
- Headaches or dizziness
- Bone pain
- Lumps in collarbone or neck region
- Swelling of the face, neck or arms
Dr. Sandeep Nayak one of the best oncologist in India says that “Some of the symptoms may be caused by something else than lung cancer but, if you have any of these signs, then you should consult the doctor right away.”
Causes of lung cancer
The major cause of lung cancer is tobacco smoking. 90% people get affected by lung cancer because of the consumption of tobacco. But there are some minor aspects that may contribute to lung cancer.
- Smoking (passive & active)
- Lung diseases
- Air pollution
- Radon gas
Stages of lung cancer
The stages of lung cancer will tell you the size of the tumor and how far it has spread in the body. As there are two types of lung cancer non-small cell lung cancer and small cell lung cancer, the stages for both are as follows:
Non-small cell lung cancer has four stages.
- Stage 1
In stage 1, the cancer is found in the lungs but not spread outside of the lung.
- Stage 2
In stage 2 lung cancer, the tumor is found in the lung and it may have spread to nearby lymph nodes.
- Stage 3
In stage 3 lung cancer, the tumor has spread in the lung organ, in lymph nodes and in the middle of the chest. It may have spread to other side of the chest and or to lymph nodes above collarbones.
- Stage 4
In stage 4 lung cancer, the tumor has spread to both of the lungs, in the surrounding area around the lung or to distant organs.
Small – cell lung cancer has 2 main stages.
- Limited stage – In this stage, a cancer tumor affects one of the lungs or near the lymph nodes.
- Extensive stage – In extensive-stage, cancer tumor has spread throughout the lung, to the nearby lymph nodes, and to the distant organs.
Treatment option for Lung cancer
Treatment for lung cancer depends on the type of lung cancer and how the advanced stage of cancer. The stage of the cancer is important because it helps with the treatment decision and provides information to predict long-term survival. The stage of a cancer is a description of the location of cancer and sites where it is spread.
Treatments for non – small cell lung cancer may include surgery, chemotherapy, radiation therapy, immunotherapy, and targeted drug therapy. Sometimes a combination of treatments is used in order to treat cancer properly. For small cell lung cancer, the treatment options are radiation therapy and chemotherapy.
Surgery is usually used to treat non- small cell lung cancer. Dr. Sandeep Nayak, one of the best oncologists in India prefers minimally invasive surgery for all early-stage lung cancer. Dr. Sandeep Nayak is a surgical oncologist at MACS clinic with experience of 19+ years. He is the pioneer of laparoscopy and robotic cancer surgery in India.
Robotic cancer surgery allows accurate and precise results in microsurgeries. Robotic and laparoscopy surgery makes cancer treatment simpler and comfortable for the patient.
Dr. Sandeep Nayak is specialized in treating early-stage lung cancer by robotic and laparoscopy cancer surgery. Minimally invasive surgery has several advantages like minimal scars, less pain and fast recovery time and many more. If you looking for any cancer treatment, you can visit Dr. Sandeep Nayak’s website
