Brachytherapy in Mumbai, India

Brachytherapy is a form of radiation treatment in which a radioactive source is placed inside or very close to the tumour. This allows a high dose of radiation to target the affected area while limiting exposure to nearby healthy tissues.

Unlike external radiation methods, this approach works from within the body. It is often used in carefully selected cases where precise treatment delivery is important. The technique may be used alone or alongside other therapies, depending on the condition and treatment plan.

Alternative Name for Brachytherapy

Brachytherapy is commonly referred to as internal radiation therapy. This name highlights the way treatment is delivered from within the body, placing the radiation source close to the target area rather than directing it from outside.

Types of Brachytherapy

Brachytherapy can be delivered in different ways depending on how long the radioactive source remains in place and how the dose is administered.

Low-Dose Rate (LDR) Brachytherapy

In this method, a low level of radiation is delivered continuously over an extended period. The radioactive source remains in place for hours or days, allowing gradual exposure that targets the affected area while limiting sudden intensity.

High-Dose Rate (HDR) Brachytherapy

This approach delivers a stronger dose of radiation over a shorter duration, usually in multiple planned sessions. The radioactive source is inserted temporarily and removed after each session, allowing precise control over dose and timing.

Permanent Brachytherapy

Small radioactive seeds are placed directly into or near the treatment area and left in the body. Over time, they release radiation at a controlled rate and gradually lose activity without needing removal.

Temporary Brachytherapy

In this method, radioactive material is placed inside the body for a defined period and then removed once the treatment is complete. It allows flexibility in controlling exposure and is commonly used when repeated sessions are required.

Preparation for Brachytherapy Procedure

Preparation involves a structured evaluation to ensure the treatment is suitable and safe. The care team assesses the location of the condition and plans the exact placement of the radioactive source.

Before the procedure, patients may be advised to:

• Undergo imaging to guide treatment planning
• Review medications and pause certain drugs if needed
• Follow specific dietary or fasting instructions
• Discuss existing medical conditions

Proper preparation helps ensure accurate treatment delivery and reduces the chance of complications.

Brachytherapy Procedure

Pre-Procedure

Before the treatment begins, careful planning is carried out to determine how the radiation will be delivered. This stage ensures precision and safety while preparing the patient for the procedure itself.

During this phase:

• The treatment area is identified using imaging
• Anaesthesia may be given depending on the method
• Special applicators or catheters are positioned to guide the radiation source

During Procedure

The actual procedure focuses on placing the radioactive material in the planned position. The process is controlled and monitored to ensure accurate delivery of radiation.

During treatment:

• The radiation source is introduced through the applicators
• The placement is verified for accuracy
• The duration depends on the type of brachytherapy used
• Patients are monitored throughout the process

The experience varies, but many procedures are completed within a few hours or in scheduled sessions.

Post-Procedure

After the treatment, attention shifts to recovery and monitoring. The care team ensures that the patient is stable and provides guidance for the next phase.

Following the procedure:

• Applicators may be removed if the treatment is temporary
• Patients are observed for any immediate side effects
• Instructions for home care are provided
• Follow-up visits are scheduled to track progress

Recovery timelines differ depending on the treatment type and individual response.

Risks of Brachytherapy

Like any medical procedure, brachytherapy involves certain risks. These are generally manageable and vary based on the treatment area and method used.

Common risks include:

• Mild discomfort at the treatment site
• Temporary swelling or irritation
• Fatigue following the procedure

Healthcare providers reduce these risks by:

• Careful treatment planning
• Using precise imaging guidance
• Monitoring the patient throughout the procedure

Complications After Brachytherapy Treatment

Although uncommon, some complications may develop after treatment, especially if the surrounding tissues are sensitive.

Possible complications include:

• Infection at the insertion site
• Bleeding or local irritation
• Effects on nearby organs depending on the treatment location

Signs to watch for:

• Persistent pain or swelling
• Fever or unusual discharge
• Changes in normal bodily functions

If any of these occur, it is important to contact the healthcare provider promptly for evaluation and care.

Why Choose Brachytherapy Treatment

Brachytherapy is often selected because of its targeted approach and ability to deliver treatment directly where it is needed. This precision helps protect surrounding healthy tissues while focusing on the affected area.

Key advantages include:

• Focused radiation delivery
• Reduced exposure to nearby structures
• Shorter treatment duration in some cases
• Ability to combine with other treatment methods when required

The decision to use brachytherapy is based on individual clinical needs and treatment goals.

Frequently Asked Questions

1. How is brachytherapy different from external beam radiation therapy?

Brachytherapy delivers radiation from within the body, while external beam therapy directs radiation from outside. This allows brachytherapy to focus more closely on the treatment area.

2. Who is not a candidate for brachytherapy?

It may not be suitable for individuals where the tumour location or size makes internal placement difficult, or when certain health conditions limit the procedure.

3. What types of cancers can be treated with brachytherapy?

It is commonly used for cancers affecting areas such as the prostate, cervix, breast, and certain head and neck regions.

4. What type of doctor performs brachytherapy?OverviewOverview

A radiation oncologist, supported by a specialised medical team, performs this procedure.

5. Who are the candidates for brachytherapy?

Patients with localised conditions that can be targeted precisely are often considered suitable candidates.

6. Is there an alternative to brachytherapy?

Other treatment options may include external radiation, surgery, or systemic therapies, depending on the condition.

7. What should I expect during my brachytherapy procedure?

You can expect careful preparation, guided placement of the radiation source, and monitoring throughout the treatment.

8. How effective is brachytherapy in treating cancer?

It is considered effective in selected cases where targeted radiation can be delivered accurately.

9. Can brachytherapy be combined with other cancer treatments?

Yes, it is often used alongside other treatments to achieve better outcomes.

10. What is the recovery time after brachytherapy?

Recovery depends on the type of procedure, but many patients resume normal activities within a short period.
