Brachytherapy treatment in Gachibowli, Hyderabad

Brachytherapy is a radiotherapy procedure that involves placing radioactive material inside the body.

Brachytherapy is sometimes called internal radiation.

Brachytherapy allows for the delivery of higher doses of radiation to more-specific areas of the body than the external beam radiation therapy.

Brachytherapy may cause fewer side effects than external beam radiation, and the overall treatment time is usually shorter with brachytherapy.

Brachytherapy can be used as a single modality treatment or in conjunction with other cancer treatments. For example, brachytherapy is sometimes used after surgery to destroy any cancer cells that may remain.

Types of brachytherapy

There are three types of brachytherapy:

  • Low-dose rate (LDR) implants: The radiation source stays in place for 1 to 7 days in this type of brachytherapy.
  • High-dose-rate (HDR) implants: In this type of brachytherapy, the radiation source is left in place for just 10 to 20 minutes and then taken out. Treatment happens twice a day for 2 to 5 days or once a week for 2 to 5 weeks. The schedule depends on the type of cancer.
  • Permanent implants: After the radiation source is inserted, the catheter is removed. The implants remain in the body for the rest of life, but the radiation gets weaker each day. As time goes on, almost all the radiation will go away.

Several types of cancer can be treated using brachytherapy

Breast cancer, Cervical cancer, Endometrial cancer, Esophageal cancer, Eye cancer, Head and neck cancer, Prostate cancer, Skin cancer, Soft tissue cancers, Vaginal cancer.

How is Brachytherapy Used?

Brachytherapy treatment involves inserting radioactive material in the body near to tumor.

Placement may be inside a body cavity or in body tissue:

Radiation is placed inside a body cavity.

  • It is called intracavity brachytherapy wherein a device containing radioactive material is placed in the windpipe or the vagina. The device may be a tube or cylinder made to fit the specific body opening.
  • A brachytherapy device is placed by hand or uses a computerized machine to help put the device.
  • Imaging equipment, such as a CT scanner or ultrasound machine, is used to ensure the device is inserted in the most effective location.

Radiation is inserted into body tissue.

  • Devices containing radioactive material are placed within body tissue, such as the breast or prostate and is called interstitial brachytherapy
  • Devices that deliver interstitial radiation into the treatment area include wires, balloons, and tiny seeds.
  • Uses needles or special applicators.
  • Narrow tubes (catheters) may be placed during surgery in some cases and later filled with radioactive material during brachytherapy sessions.
  • CT scans, ultrasound, or other imaging techniques are used to guide the devices into place and ensure their position in the most-effective locations.
