What Is Radiation Therapy and How Is It Used for Cancer Treatment?

Radiation therapy (also called radiotherapy) uses high-energy rays to kill cancer cells or shrink tumors. It can be given externally (from a machine outside the body) or internally (placed near cancer). Radiation helps destroy cancer cells while sparing healthy tissues as much as possible. It is used for many cancers, either alone or with surgery and chemotherapy. The exact plan depends on cancer type, stage, and patient health. Side effects may include fatigue, skin changes, and temporary discomfort, which doctors help manage during and after treatment.

Types of Radiation Therapy

Radiation therapy can be given in different ways depending on the medical condition:

• External Beam Radiation Therapy:
• Internal Radiation Therapy (Brachytherapy):
• Image-Guided Radiation Therapy (IGRT):

The doctor decides the best method based on the cancer type and treatment goal.

Conditions Treated With Radiation Therapy

Radiation therapy is used to treat many types of cancer, including breast cancer, lung cancer, prostate cancer, head and neck cancer, brain tumors, and gynecological cancers. It may also be used to relieve symptoms such as pain, bleeding, or pressure caused by tumors.

Radiation Therapy Procedure

Before starting treatment, patients go through a planning session where imaging scans are done to mark the exact treatment area. During each session, the patient lies still while the radiation machine delivers treatment to the targeted area. Each session usually lasts a few minutes and is painless.

Radiation therapy is commonly given over several sessions spread across days or weeks to allow healthy cells time to recover.

Benefits of Radiation Therapy

• Helps destroy or shrink cancer tumors
• Can be used before or after surgery
• Non-invasive treatment option
• Helps relieve cancer-related symptoms
• Improves treatment outcomes when combined with other therapies

Side Effects of Radiation Therapy

Side effects depend on the treatment area and radiation dose. Common side effects include tiredness, skin redness, mild swelling, and temporary discomfort. Most side effects improve after treatment ends. Doctors monitor patients closely and provide guidance to manage side effects.

Recovery and Follow-Up

Recovery after radiation therapy varies from person to person. Some patients return to normal activities during treatment, while others may need rest. Regular follow-up visits are important to track progress, manage side effects, and evaluate treatment results.
