Lung Cancer Treatment and Latest Treatment Options


Lung cancer treatment course can be divided into four courses:

Surgery
Lung Cancer TreatmentUsually surgery is done in lung cancer stage 1 and 2 to remove the lung cancer tumor. The area or small portion of the lung where tumor has grown would be removed. Mostly this procedure is performed by making a small incision in the chest and inserts a tube called thoracoscope. With the aid of thoracoscope the affected in the area in the lung is removed.

Radiation as lung cancer treatment 

Radiation therapy, high energy radiation dose is given to kill the targeted cancer cells or tumor. Usually radiotherapy is used to treat all the types of cancer. Oncologist decides the number and size of doses to be given to the patient based on the stage and severity. Other factors like age, immunity, health status, stage of cancer also contribute in deciding the radiotherapy.

Chemotherapy as ling cancer treatment 

Chemotherapy is an anticancer cytotoxic drugs used to kill the cancer cells. Chemotherapy inhibits the growth of cancer cells. Adjuvant chemotherapy or chemotherapy after surgery usually helps to prevent re-growth of cancer cells in stage 2 and 3. Patients with lung cancer stage 3 and 4, tumor cannot be removed by surgically because in stage 3 and 4 cancer cells usually spreads other parts of the body and chemotherapy is the main treatment in this stages. Oncologist prescribes anti cancer medicine along with chemotherapy plan.

Targeted Treatment as lung cancer treatment 

Patient with advance stages in lung cancer receives targeted treatment along with chemotherapy. Targeted treatment is specifically designed to kill the cancer cells by blocking the targets in the surface of the cancer cells. The targeted treatment include

Erlotinib (Tarceva)

Erlotinib (Tarceva) is beneficial for patient with non-small cell lung cancer. Erlotinib (Tarceva) blocks the receptors, the epidermal growth factor receptor (EGFR) on the surface of the cancer cells. This inhibits the growth and multiplication of cancer cells.

Bevacizumab (Avastin)

Tumor cells need blood supplies same as normal cells. This drug blocks the supply of blood to the tumor cells, thus tumor cells cannot stimulate to grow new blood vessels like normal cells do.

Crizotinib (Xalkori)

Effective for patient with advanced non–small cell lung cancer. This medicine block ALK in cancer cells resulting in growth inhibition.
