Lung cancer is caused by a number of external or internal stimuli. The signs of lung cancer vary from person to person. Certain home remedies exist that aim at preventing it, while several others focus on stimulating the activities of the immune system. There are also certain kinds of foods that are beneficial when taken by patients undergoing chemotherapy or radiation therapy.
There are two main types of lung cancer- small cell lung cancer and non-small cell lung cancer. These categories refer to what the cancer cells look like under a microscope. Non-small cell lung cancer is more common than small cell lung cancer.
Treatments For Cancer
There are various treatments for cancer. Let us discuss them all in detail below.
Lung cancer surgery
You and your doctor choose a cancer treatment plan based on a number of factors, such as your overall health, the type and stage of your cancer, and your preferences.
In some cases, you may choose not to undergo lung cancer treatment. For instance, you may feel that the side effects of treatment will outweigh the potential benefits. When that’s the case, your doctor may suggest comfort care to treat only the symptoms the cancer is causing, such as pain or shortness of breath.
During surgery your surgeon works to remove the lung cancer and a margin of healthy tissue. Procedures to remove lung cancer include:
- Wedge resection to remove a small section of lung that contains the tumor along with a margin of healthy tissue
- Segmental resection to remove a larger portion of lung, but not an entire lobe
- Lobectomy to remove the entire lobe of one lung
- Pneumonectomy to remove an entire lung
If you undergo surgery, your surgeon may also remove lymph nodes from your chest in order to check them for signs of cancer.
Surgery may be an option if your cancer is confined to the lungs. If you have a larger lung cancer, your doctor may recommend chemotherapy or radiation therapy before surgery in order to shrink the cancer. If there’s a risk that cancer cells were left behind after surgery or that your cancer may recur, your doctor may recommend chemotherapy or radiation therapy after surgery.
Advanced surgical techniques such as minimally invasive surgery and video-assisted thoracoscopic surgery (VATS) may reduce the amount of time you need to spend in the hospital after lung cancer surgery and may help you return to your normal activities sooner. Research shows that people who undergo minimally invasive lung cancer surgery at hospitals that perform many of these operations every year tend to experience less pain and fewer complications. Mayo Clinic surgeons perform more than 900 VATS procedures every year.
Radiation therapy uses high-powered energy beams from sources such as X-rays and protons to kill cancer cells. During radiation therapy, you lie on a table while a machine moves around you, directing radiation to precise points on your body.
For people with locally advanced lung cancer, radiation may be used before surgery or after surgery. It’s often combined with chemotherapy treatments. If surgery isn’t an option, combined chemotherapy and radiation therapy may be your primary treatment.
For advanced lung cancers and those that have spread to other areas of the body, radiation therapy may help relieve symptoms, such as pain.
When compared with standard radiation therapy techniques, newer and precisely targeted treatments may be more effective and cause fewer side effects. Mayo Clinic offers cutting-edge radiation planning and treatment technologies, including intensity-modulated radiation therapy, volumetric modulated arc therapy, image-guided radiation therapy and proton therapy.
Chemotherapy uses drugs to kill cancer cells. One or more chemotherapy drugs may be given through a vein in your arm (intravenously) or taken orally. A combination of drugs usually is given in a series of treatments over a period of weeks or months, with breaks in between so that you can recover.
Chemotherapy is often used after surgery to kill any cancer cells that may remain. It can be used alone or combined with radiation therapy. Chemotherapy may also be used before surgery to shrink cancers and make them easier to remove.
In people with advanced lung cancer, chemotherapy can be used to relieve pain and other symptoms.
Stereotactic body radiotherapy, also known as radiosurgery, is an intense radiation treatment that aims many beams of radiation from many angles at the cancer. Stereotactic body radiotherapy treatment is typically completed in one or a few treatments.
Radiosurgery may be an option for people with small lung cancers who can’t undergo surgery. It may also be used to treat lung cancer that spreads to other parts of the body, including the brain.
Targeted drug therapy
Targeted drug treatments focus on specific abnormalities present within cancer cells. By blocking these abnormalities, targeted drug treatments can cause cancer cells to die.
Many targeted therapy drugs are used to treat lung cancer, though most are reserved for people with advanced or recurrent cancer.
Some targeted therapies only work in people whose cancer cells have certain genetic mutations. Your cancer cells may be tested in a laboratory to see if these drugs might help you.
Immunotherapy uses your immune system to fight cancer. Your body’s disease-fighting immune system may not attack your cancer because the cancer cells produce proteins that blind the immune system cells. Immunotherapy works by interfering with that process.
Immunotherapy treatments are generally reserved for people with advanced lung cancer.
Mayo Clinic researchers made an important discovery that lead to immunotherapy treatments called immune checkpoint inhibitors that have revolutionized care for people with metastatic lung cancer.
People with lung cancer often experience signs and symptoms of the cancer, as well as side effects of treatment. Supportive care, also known as palliative care, is a specialty area of medicine that involves working with a doctor to minimize your signs and symptoms.
Your doctor may recommend that you meet with a palliative care team soon after your diagnosis to ensure that you’re comfortable during and after your cancer treatment.
In one study, the lung cancer survival rate of people with advanced non-small cell lung cancer that began receiving supportive care soon after their diagnosis is higher. Those receiving supportive care reported improved mood and quality of life. They survived, on average, almost three months longer than did those receiving standard care.
