What is radiation therapy? According to wikipedia Radiation therapy discovered in 1889 also known as radiotherapy, radiation oncology, or XRT, is the medical use of ionizing radiation as a part of cancer treatment to control malignant cells. Radiotherapy may be used for curative or adjuvant cancer treatment, with curative being the cure and adjuvant being additional treatment. Radiation therapy can also be used as palliative treatment, which is where a cure is not possible and the aim is for disease control or relief of symptoms. It can also be used as therapeutic treatment, where the therapy can result in surviving the cancer and the cancer can be cured. A radiotherapy technique used to prepare the body to receive a bone marrow transplant is known as total body irradiation (TBI). There are several different types of radiation therapy including external beam radiotherapy, Brachytherapy, and systemic radioisotope therapy. From its discovery in the 19th century radiation therapy has come a long way through research and innovation. Radiation therapy can be used in non-malignant cancer treatment or malignant cancer treatment. Radiation therapy has several applications in non-malignant conditions, such as the treatment of trigeminal neuralgia, severe thyroid eye disease, apterygial, pigmented villonodular synovitis, prevention of keloid scar growth, and prevention of heterotopy ossification. The use of radiation therapy in non-malignant conditions is limited due to the risk cancers that may be radiation-induced. Radiation therapy is also used for the treatment of malignant tumors, and is often used as the primary therapy. It is also common to combine radiotherapy with surgery, chemotherapy, hormone therapy or some mixture of the three. Almost all common types of cancer can be treated with radiation therapy in some way. The precise treatment intent (curative, adjuvant, neoadjuvant, therapeutic, or palliative) will depend on the tumor type,

    Brachytherapy (also known as internal radiation therapy) is the use of radioactive ‘seeds’ to help destroy cancerous cells. It is commonly used as a treatment for cervical, prostate, breast and skin cancer. How long the treatment will take will depend on where the tumor is and how large it is. Brachytherapy works from the inside of the body by placing the radioactive ‘seeds’ into the body next to the tumor.

Independently of histology, radiation plays a central role and has shown to increase local tumor control. Developments in radiation oncology are always aiming at an increase precision of dose delivery: More conformal coverage of target volumes, steep dose gradients to surrounding tissues, and sparing of organs at risk (OAR). In photon therapy, based on 3D-RT, stereotactic radiotherapy was a big step…
