Radiation Therapy

Radiation Therapy‏‎, also known as Radiotherapy, is a type of cancer treatment that uses high doses of radiation to kill cancer cells and shrink tumors. It is one of the most common treatments for cancer, either by itself or along with other forms of treatment.

History

The use of radiation therapy in the treatment of cancer dates back to the early 20th century, with the discovery of X-rays by Wilhelm Conrad Roentgen in 1895. The first reported use of radiation therapy in cancer treatment was by Emil Grubbe in Chicago in 1896, just a year after the discovery of X-rays.

Types of Radiation Therapy

There are several types of radiation therapy, including external-beam, internal, and systemic radiation therapy.

External Beam Radiation Therapy

In external beam radiation therapy, the radiation is delivered from a machine outside the body. This is the most common type of radiation therapy.

Internal Radiation Therapy

Internal radiation therapy, also known as Brachytherapy, involves placing radiation inside your body, in or near the cancer cells.

Systemic Radiation Therapy

Systemic radiation therapy involves swallowing or injecting a radioactive substance, which travels through your body, seeking out and killing cancer cells.

Side Effects

Like all cancer treatments, radiation therapy can cause side effects. These can include fatigue, skin problems, and other side effects depending on the part of the body being treated.

Future Developments

Advancements in technology and medical research continue to shape the future of radiation therapy. Techniques such as Intensity-Modulated Radiation Therapy (IMRT) and Image-Guided Radiation Therapy (IGRT) are providing more precise and effective treatment options.
