Cancer is the deadliest disease of this century. Chemotherapy, surgery, proton therapy, cryotherapy, radiation, etc. are just some of the treatment methods. Radiation treatment occurs in approximately 50-60% of cancer patients. This method of cancer treatment is used for almost all types of cancer such as breast, pancreas, prostitution, uterus, lung, leukemia, cancer of the lymphatic system, soft tissue sarcoma, etc.
Radiation therapy is a targeted treatment where cancer cells are directed to destroy it. This treatment affects the ability of cancer cells to replicate and spread cancer. There are several advanced methods of radiotherapy as proton beam therapy, radio, etc.
What is radiotherapy?
Radiation therapy can be defined by ionizing radiation from targeted cell therapy to destroy cancer cells. This radiation can destroy normal cells in close proximity. But most normal cells can recover. The maximum destruction of cancer cells is the goal of the treatment. Radiation therapy is used to completely destroy a tumor or shrink the tumor to relieve the symptoms.
There are cases where radiation therapy is used as symptomatic treatment or palliative symptom therapy such as pain relief and patient improvement.
Several methods of radiotherapy
There are basically two types of radiotherapy - external radiotherapy and internal radiation. The effectiveness of external radiation therapy can be achieved using a number of refined techniques, such as three-dimensional conformational radiotherapy, radiation therapy, IMRT, and PBRT. Stereo radiation therapy is a method used to treat brain tumors. Brachytherapy is a more advanced method.
The Efficacy of Radiation Therapy for Different Types of Cancer
Radiation therapy prolongs the survival of patients with cancer. Like any treatment different cells react differently to them as well as treatment. Sensitivity to radio is the response of cancer cells. Radiation dose is the term used to describe the amount of radiation absorbed by cancer cells. Extremely sensitive cancer cells, such as blood cancer and germ cell tumors, were rapidly destroyed by minimal doses of radiation. Moderately sensitive cells such as skin cancer cells require a higher dose of radiation. There are cells that are resistant to radio. Cancer of renal melanoma cells and are good examples. In such cases, a higher dose of radiation is preferred. Neopemia can not be cured, as cancer spreads cells across the body. Radio-responsive tumors are usually treated with therapeutic doses of radiation.
Size is also important in the treatment of cancer. Small tumors are more sensitive than large tumors. Surgery before treatment is a common procedure. The use of introductory chemotherapy before radical radiotherapy is another method. Several drugs such as cetuximab, cisplatin, etc. are administered prior to radiotherapy.
