What should you know about low dose rate brachytherapy?

A radiation specialist positions a source inside a body cavity or within tissue. The source may remain in place for a planned period or be implanted as small seeds, depending on the cancer and treatment design. The radiation is strongest close to the source and reduces with distance. Low-dose-rate treatment is used in selected cancers, including some prostate, cervical, womb, and vaginal cancers. Imaging and examination guide placement.

Your team explains anaesthesia, imaging, the insertion procedure, medicines, and practical restrictions after treatment. Ask whether the source is temporary or remains in the body and whether special precautions are needed around children or pregnant people. An afterloader may move a source into an applicator for treatment and remove it afterward. Recovery advice varies with the treated area and may include care for urinary, bowel, vaginal, or local skin symptoms.

Contact your treatment team urgently for heavy bleeding, severe or increasing pain, fever, inability to pass urine, new weakness, or unexpected discharge. Follow the specific radiation-safety instructions supplied by your centre, especially if seeds remain implanted. Seek emergency help for severe breathing difficulty, collapse, or uncontrolled bleeding.

Ask why low-dose-rate treatment suits your tumour, where the source will be placed, how long it will remain, and how its position will be checked. Clarify likely short-term effects, fertility or sexual-health considerations, travel guidance, and which symptoms need same-day contact.
