Radiotherapy is a type of cancer treatment that uses radiation to kill cancer cells. Radiation can be delivered in many different ways, including through the skin, by injecting it directly into the tumor, or by passing it through a material like glass or water. Radiotherapy for cancer can be used on its own, in combination with other treatments, or as part of a clinical trial.
Radiotherapy for Cancer Treatment
Radiotherapy for cancer is a type of treatment that uses radiation to kill cancer cells. Radiation therapy can be delivered through the air, through the body, or into the surrounding area. Radiotherapy can be used to treat a wide range of cancers, including:
Non-small cell lung cancer (NSCLC)
Squamous cell lung cancer (SCLC)
Lung cancer that has spread to other parts of the body
Colon cancer
Breast cancer
Cervical cancer
Metastatic prostate cancer
Side-effects of Radiotherapy
Radiation therapy is often effective in treating various types of cancers. However, it can also have some side effects, including:
Nausea and vomiting
Fatigue
Hair loss
Brittle nails
However, most side effects are mild and typically go away after treatment is complete. Some people may experience more serious side effects, such as:
Skin damage from the radiation exposure
Hearing loss from the radiation exposure
Damage to internal organs from the radiation exposure
How does Radiotherapy Work?
Radiation therapy works by damaging the cells in a tumor. The damage causes the cells to die, which can stop or slow the growth of the tumor. Radiotherapy can be used in combination with other treatments, such as chemotherapy, to improve the chances of success.
There are several types of radiation therapy that can be used to treat different types of cancers:
External beam radiation therapy (EBRT)
Brachytherapy
Stereotactic radiosurgery (SRS)
Targeted radiotherapy (TRT)
EBRT is usually the first choice for treating most cancers because it gives larger doses over a shorter period of time. Brachytherapy involves placing small sources of radiation inside the tumor itself, while SRS and TRT use high-powered beams or particles directed at specific parts of the tumor. There are many risks and benefits associated with radiotherapy treatment, and patients should discuss these risks and benefits with their cancer doctor before starting treatment. Overall, radiotherapy remains one of the most effective interventions available for treating various cancers.
Conclusion
Radiotherapy for cancer is a treatment that uses high-energy radiation to kill cancer cells. The therapy is available as either whole-body or localized radiotherapy, and it can be used in combination with other treatments such as chemotherapy and surgery. While there are many different types of cancer that can be treated with radiotherapy, its success depends on the type of cancer and how well it has spread. Therefore, it is important to get accurate information about your individual tumor from cancer doctors so that you can make an informed decision about whether or not radiotherapy is right for you.
