What is the Role of Brachytherapy in the Treatment of Cervical Cancer?

You must have come across the term “Brachytherapy” while seeking treatment for cervical cancer. But do you know how this treatment method plays a pivotal role in combating cervical cancer? The best cancer doctor in Kolkata shares some valuable insights related to the same. Read on to clarify your doubts and understand Brachytherapy’s importance:

What is Brachytherapy?

Brachytherapy is a targeted radiation therapy where radioactive implants are placed near the cancer site, such as the cervix or uterus. This method allows precise radiation delivery while minimizing damage to surrounding healthy tissues. 


Difference from External Beam Radiation Therapy

Unlike external beam radiation therapy (EBRT), which uses a machine to deliver radiation from outside the body, brachytherapy involves placing the radiation source directly into the tumour area. This treatment technique is particularly effective when combined with EBRT or other treatments like chemotherapy.


Procedure and Types of Brachytherapy

According to the best cancer doctor in Kolkata, there are different types of Brachytherapy, such as:

  • Low-Dose Rate (LDR) Brachytherapy: LDR brachytherapy involves placing radioactive material near the tumour for 1 to 7 days. It delivers a continuous, low radiation dose, requiring hospitalization for monitoring.

  • High-Dose Rate (HDR) Brachytherapy: HDR brachytherapy delivers intense radiation directly to the tumour in sessions lasting 10 to 20 minutes. Patients can typically go home between treatments due to the brief exposure.

  • Pulse-Dose Rate (PDR) Brachytherapy: PDR brachytherapy administers radiation in short pulses for 10 to 30 minutes per hour. This method offers flexibility in treatment delivery while effectively targeting cancerous tissues.


Managing Side Effects and Complications

Short-term side effects of brachytherapy, such as vaginal irritation and abdominal discomfort, are temporary and manageable with medications and lifestyle adjustments. Long-term risks like vaginal stenosis or rectal complications are possible but they can be monitored and treated by your oncologist.


Brachytherapy offers relief and hope to those fighting against cervical cancer. For expert care, consult the best cancer doctor in Kolkata and learn the advantages of brachytherapy, which can make a difference.

Gastric cancer, also known as stomach cancer, can be challenging to treat, but chemotherapy offers a powerful weapon in the fight against this disease. Consulting a  gastrointestinal cancer doctor in Kolkata  can provide insights into how chemotherapy works for gastric cancer. What is Chemotherapy? Chemotherapy involves the use of drugs to destroy cancer cells. These drugs can be administered orally or intravenously and target and kill rapidly dividing cells, including cancer cells. How Does Chemotherapy Target Gastric Cancer? Interfering with Cell Division Chemotherapy drugs disrupt cell division. Cancer cells divide more rapidly than most normal cells, making them especially vulnerable to these drugs. By interfering with their ability to reproduce, chemotherapy can shrink tumours and slow the progression of the disease. Damaging Cancer Cell DNA Chemotherapy drugs can damage the DNA of cancer cells, preventing them from growing and divi...
