lung cancer radiation
Due to the advanced stages of some lung cancer, surgery is not an option. This depends on the location of the tumor or tumors or the overall health of the person. In these types of cases, a radiation oncologist who advocate more likely to treat. Although surgery may be an option, you may the doctor who suggested this type of treatment before surgery to help shrink the tumor or after surgery to help eradicate a cancer cell remaining.
Radiation therapy – What is it? Radiation therapy – is a high power X-rays that are "beams" in the location of cells cancer, which in turn destroys rapidly dividing cells. Unfortunately, during this process, radiation kills both healthy cells as well as cancer cells there. However, there are methods of delivering radiation therapy to minimize side effects on healthy cells.
EBT – external radiation therapy or radiotherapy is a highly concentrated beam of radiation that goes directly to the tumor margins. Due to the merger, EBT minimizes the risk of harming healthy cells. EBT is delivered in "fractions", ie short duration of radiation that spread over several weeks. According to current studies, the best effects are achieved when there are more frequent, shorter than in large fractions fractions spread over a longer period of time. Talk to your doctor about what is the best time for you.
Often this therapy is used to relieve symptoms but do not actually cure itself. Doctors may prescribe radiation therapy before or after surgery and is designed to shrink the tumor or make it less active. Doctors can brachytherapy suggest instead of using an external beam. Brachytherapy is a procedure that implants small radioactive seeds directly into the cancer site. Brachytherapy can open blocked airways by reducing the size of tumors blocking the bronchi or trachea. Brachytherapy can also help stop hemorrhage in tumors.
Conformal radiation therapy is another type of therapy. This TAC therapy helps create a 3-D image of the tumor and the form of X-ray beam precisely the size and shape of the tumor. When using conformal radiotherapy, damage to surrounding tissue is removed almost completely. Intensity modulated radiation therapy can be tuned so that only affects certain areas of the tumor. This form of therapy works with precision to target TAC only cancer cells.
Any suspicion that the tumor has spread, as often happens in the case of small cell, his oncologist is likely to suggest a course of chemotherapy, either before, after or simultaneously with radiotherapy. Radiotherapy is located so the beam is focused directly on cancer cells. Use of radiotherapy in combination with chemotherapy, usually offer a better opportunity to clarify the abnormal cells and prevent recurrence. Rarely recommended radiotherapy as single treatment.
