Radiation Therapy

What is Radiation Therapy?

Radiation therapy uses high-energy rays to destroy or shrink cancer cells. It is one of the most common treatments for cancer, either alone or with surgery and chemotherapy.

How Does It Work?

Radiation damages the DNA of cancer cells, preventing them from growing and dividing. The treatment is carefully targeted to avoid harming healthy tissue.

Types of Radiation Therapy

• External Beam Radiation: Uses a machine to direct radiation to the tumor.
• Internal Radiation (Brachytherapy): Implants a radiation source inside the body.

Side Effects

Side effects depend on the treatment area and may include fatigue, skin irritation, or nausea. Newer techniques help minimize these effects.
