Radiation therapy or radiotherapy, often abbreviated RT, RTx, or XRT, is therapy using ionizing radiation, generally as part of cancer treatment to control or kill malignant cells and normally delivered by a linear accelerator.

Radiation therapy may be curative in a number of types of cancer if they are localized to one area of the body.

It may also be used as part of adjuvant therapy, to prevent tumor recurrence after surgery to remove a primary malignant tumor (for example, early stages of breast cancer).

Radiation therapy is synergistic with chemotherapy, and has been used before, during, and after chemotherapy in susceptible cancers.

The subspecialty of oncology concerned with radiotherapy is called radiation oncology.

Oncology is a branch of medicine that deals with the prevention, diagnosis and treatment of cancer.

A medical professional who practices oncology is an oncologist.

The name's etymological origin is the Greek word ὄγκος (ónkos), meaning "tumor", "volume" or "mass".

Cancer is a group of diseases involving abnormal cell growth with the potential to invade or spread to other parts of the body.

Not all tumors are cancerous; benign tumors do not spread to other parts of the body.

Possible signs and symptoms include a lump, abnormal bleeding, prolonged cough, unexplained weight loss and a change in bowel movements.

While these symptoms may indicate cancer, they may have other causes.

Over 100 types of cancers affect humans.

A physician, medical practitioner, medical doctor, or simply doctor is a professional who practises medicine, which is concerned with promoting, maintaining, or restoring health through the study, diagnosis, and treatment of disease, injury, and other physical and mental impairments.

Physicians may focus their practice on certain disease categories, types of patients and methods of treatment—known as specialities—or they may assume responsibility for the provision of continuing and comprehensive medical care to individuals, families, and communities—known as general practice.

Medical practice properly requires both a detailed knowledge of the academic disciplines (such as anatomy and physiology) underlying diseases and their treatment—the science of medicine—and also a decent competence in its applied practice—the art or craft of medicine.

Therapy (often abbreviated tx, Tx, or Tx) is the attempted remediation of a health problem, usually following a diagnosis.

In the medical field, it is usually synonymous with treatment (also abbreviated tx or Tx).

Among psychologists and other mental health professionals, including psychiatrists, psychiatric nurse practitioners, and clinical social workers, the term may refer specifically to psychotherapy (sometimes dubbed 'talking therapy').

The English word therapy comes via Latin therapīa from and literally means "curing" or "healing".
