Lung cancer is when abnormal cells grow in the lungs. It can spread to other areas of the body and cause different symptoms. Small cell and non-small cell are types of lung cancer. Non-Small Cell Lung Cancer starts in the flat cells that line the airways and can grow quickly. It is often caused by smoking. Chemotherapy uses drugs to kill cancer cells. It can be used at different times in treatment to achieve different goals, such as shrinking the tumor before surgery or killing leftover cancer cells after surgery. It can also be given alone or to control symptoms and side effects. Squamous cell and adenocarcinoma carcinoma are the most common. They usually grow more slowly than other types of lung cancer and are less likely to spread to other parts of the body. Some people with Non-Small Cell Lung Cancer have a device surgically implanted in their chest, either a pump, catheter or port to give them chemotherapy through a tube called a vein (intravenous or IV) directly into the bloodstream. Other people take chemotherapy pills by mouth. Survival rates for NSCLC vary widely based on a number of factors, including the person’s age and general health, the type of cancer and how it is treated. Statistics only provide averages and can’t tell whether cancer will shorten their life or not. The cancer drugs in targeted therapy interfere with the molecular abnormalities that drive tumor growth. They can also deliver toxins that kill cancer cells without harming healthy cells. Doctors may recommend this treatment if the results of the biopsy show certain genetic changes. NYU Langone’s Perlmutter Cancer Center has a variety of targeted therapies to treat lung cancer, including small-molecule drugs that block specific proteins that help tumors grow. Other targeted drugs, known as angiogenesis inhibitors, starve the tumor by blocking its ability to make new blood vessels that bring it nutrients. Targeted therapy can be used alone or in combination with surgery, radiation, and chemotherapy. It can lower the chances of cancer coming back after surgery. Immunotherapy uses the body’s immune system to fight cancer. A care team may recommend immunotherapy alone or in combination with chemotherapy and/or radiation therapy. Scientists make drugs in the lab to help the immune system find and kill cancer cells more easily. Some of these drugs, called monoclonal antibodies, block checkpoint molecules like CTLA-4 and PD-L1 that prevent the immune cells from attacking cancer cells. Other monoclonal antibodies carry a drug or radioactive substance that targets specific markers (called antigens) on cancer cells. Still others, known as bi-specific T cell-engaging antibodies, bind to both cancer cells and the immune system’s T cells, which helps the body attack the tumor more effectively. Immunotherapy doesn’t work for everyone, and it takes time to see results. Sometimes, a doctor may prescribe a cancer vaccine to help build an immune response. Other times, they may test the blood or tissue for specific markers that are high in cancer cells and can be targeted with immunotherapy. Surgery isn’t usually used for this type of cancer as it often spreads too far by the time doctors find it. If cancer is found very early, doctors may suggest an operation called a lobectomy or pneumonectomy to remove part of the lung. This is followed by chemotherapy or radiotherapy to destroy any remaining cancer cells. Adenocarcinoma is found in the outer area of the lung; squamous cell carcinoma, which is found in the center of the lung near an air tube (bronchus); and large cell carcinoma, which can occur anywhere in the lungs. Non-Small Cell Lung Cancer cancers grow and spread more slowly than small cell lung cancer. You can Also Read the Press Release of Non-Small Cell Lung Cancer
