Lung cancer is an uncontrolled growth of cells that start off in the lungs. Instead of developing into healthy lung tissue, the cells divide rapidly and forms malignant tumours. These malignant tumours develop in the cells of the lungs is known as lung cancer. Usually, lung cancer starts in the cells that line the air passages and it can also spread to other parts of the body.

There are two types of lung cancers based on cell size:-

• Small cell lung cancer (SCLC)
• Non-small cell lung cancer (NSCLC). 

Robotic-assisted thoracic surgery is also a type of minimally invasive thoracic surgery of the chest. RATS becomes the most advanced surgical procedure used to treat cancer. RATS require only small incisions in the chest, rather than one large incision. When compared with a traditional open operation (thoracotomy), Robotic-assisted thoracic surgery may result in less pain and scarring. 
Since Robotic-assisted thoracic surgery causes very less trauma to the body, recovery time is also reduced and post-surgery complications reduce as well.
During robotic-assisted thoracoscopic surgery, surgeons view a magnified, 3D image of the patient’s lungs and chest. With help of robotic technology yours surgeon’s movements during surgery become into precise actions, which results in better accuracy with complete resection of the cancer tissue.

 Robotic lobectomy has been projected as an alternative to VATS. Advocates for RATS describe theoretical advantages of this technique over VATS, including 3D visual image of the operative field and greater articulation of the robotic instruments. Several studies have demonstrated that robotic surgery is safe with equivalent clinical outcomes when compared with similar patients undergoing VATS.
