Understanding Radiation Therapy
What is Radiation Therapy?
Radiation therapy is a type of cancer treatment that uses high-energy radiation to kill cancer cells. It can be used to treat many types of cancer, including breast cancer, lung cancer, prostate cancer, and head and neck cancer.
How Does Radiation Therapy Work?
Radiation works by damaging the DNA of cancer cells. When DNA is damaged, cells cannot divide and grow. This can lead to the death of the cancer cells.
Types of Radiation Therapy
There are two main types of radiation therapy:
- External beam radiation therapy is delivered from a machine outside the body that directs radiation beams at the tumor.
- Internal radiation therapy (brachytherapy) involves placing radioactive materials inside or near the tumor.
Side Effects of Radiation Therapy
Radiation therapy can cause side effects, such as:
- Radiation dermatitis: Skin redness, itching, and peeling
- Fatigue: Feeling tired and weak
- Hair loss: Loss of hair in the treated area
- Nausea and vomiting: Feeling sick and throwing up
- Other side effects: Depending on the location of the tumor, other side effects may include mouth sores, diarrhea, or urinary problems
Benefits of Radiation Therapy
Radiation therapy can be an effective treatment for many types of cancer. It can:
- Shrink tumors
- Kill cancer cells
- Relieve symptoms of cancer, such as pain
- Help prevent cancer from coming back
Before Radiation Therapy
Before starting radiation therapy, your doctor will:
- Perform a physical exam and review your medical history
- Order imaging tests to locate the tumor
- Discuss the benefits and risks of radiation therapy
- Develop a treatment plan
During Radiation Therapy
Radiation therapy is usually given in daily treatments over several weeks. Each treatment typically takes a few minutes. You will lie on a table while the radiation machine moves around you.
After Radiation Therapy
After radiation therapy, your doctor will monitor your progress and follow-up with regular appointments. You may need additional treatments or tests to check for any side effects or recurrence of cancer.
