Medical Subject Headings (MeSH): Radiotherapy

Radiotherapy, also known as radiation therapy, is a form of cancer treatment that uses high-energy radiation to destroy cancer cells and shrink tumors. It is a commonly used modality in the treatment of various types of cancer, including breast, prostate, lung, and others.

Some key aspects of radiotherapy in healthcare include:

Radiation delivery: Radiotherapy uses high-energy radiation, delivered by a machine called a linear accelerator, to destroy cancer cells. The radiation can be delivered externally or internally, depending on the location and type of cancer.

Planning and simulation: Radiotherapy requires careful planning and simulation to determine the precise dose and location of the radiation. This process often involves the use of imaging technologies, such as CT scans, to create a three-dimensional model of the tumor and surrounding tissues.

Treatment delivery: Radiotherapy treatments are delivered in a series of sessions, typically over several weeks. The exact number of treatments and length of the course of therapy will depend on the type and stage of the cancer, as well as other factors.

Side effects: Radiotherapy can cause side effects, including skin irritation, fatigue, and nausea. These side effects can vary depending on the type and location of the cancer, as well as the dose and schedule of radiation.

Collaboration with other specialists: Radiotherapy is often a collaborative modality, with radiation oncologists working closely with other healthcare providers, such as medical oncologists, surgeons, and others, to provide comprehensive cancer care.

Radiotherapy is a widely used form of cancer treatment that plays a critical role in the management of many types of cancer. Effective radiotherapy practices require careful planning and simulation, as well as close collaboration with other healthcare providers, to ensure the best possible outcomes for patients.
