Brachytherapy

Overview

Brachytherapy is a type of internal radiation therapy used to treat various cancers. Unlike traditional external radiation therapy, brachytherapy involves placing a radioactive source directly inside or very close to the tumor. This method allows for delivering radiation more precisely, minimising damage to surrounding healthy tissues. It is commonly used for prostate cancer, cervical cancer and even some vaginal cancers.

Why Brachytherapy Treatment is Required?

• Used when other treatments like surgery or external radiation may not be as effective or suitable.
• Delivers radiation directly to the tumor for more precise treatment.
• Preferred for cancers in hard to treat areas like the prostate or cervix.
• May be combined with other therapies for enhanced effectiveness.

Key Advantages of Brachytherapy

• Targeted Radiation: Direct delivery of radiation to the tumor minimising damage to surrounding healthy tissue.
• Fewer Side Effects: Less severe and fewer side effects compared to external radiation.
• Convenience: Shorter treatment sessions; some types like prostate brachytherapy can be completed in one or two sessions.
• Effectiveness: Particularly effective for prostate cancer, cervical cancer and other types of cancer.

How Should You Prepare Yourself Before Taking Brachytherapy Treatment?

• Pre Treatment Imaging: CT scan or MRI to determine the tumor’s location.
• Consultation: Detailed discussion of medical history and treatment options.
• Medication Adjustments: Adjustments may be needed for certain medications like blood thinners.

How Brachytherapy is Performed?

• Prostate Cancer: Tiny radioactive seeds inserted into the prostate.
• Cervical Cancer: Radioactive sources placed inside the vagina.
• Imaging Techniques: Uses CT scans or ultrasound for precise placement of radioactive sources.

What You Can Expect Before, During, and After the Procedure?

• Before the Procedure: Imaging tests and instructions on eating, drinking and medications.
• During the Procedure: Outpatient procedure, local anesthesia or mild sedation may be used.
• After the Procedure: Mild discomfort or swelling may occur, most patients resume regular activities soon after.

Risk and Potential Complications

• Side Effects: Urinary problems, pain or vaginal irritation may occur.
• Infection: Slight risk of infection, although rare.
• Radiation Exposure: Minimal radiation exposure to others particularly right after treatment.

Results/Outcomes

• High Effectiveness: Brachytherapy is highly effective for treating prostate cancer, cervical cancer and certain other cancers.
• Localised Control: It offers excellent outcomes in achieving localised control of the cancer reducing the risk of recurrence.
• Minimal Side Effects: Often associated with fewer and less severe side effects compared to external radiation therapy.
• Prostate Cancer: Brachytherapy provides good long term survival rates with minimal side effects for prostate cancer patients.
• Cervical Cancer: Significantly shrinks tumors, relieving symptoms and improving treatment outcomes.
• Overall Success: Many patients experience substantial tumor reduction and it is considered an effective treatment option, especially for tumors in hard to treat areas.
