Radiotherapy Treatment For Cancer Everything You Need

Everything You Need to Know About Radiotherapy Treatment for Cancer

Cancer treatment has evolved tremendously over the years, offering patients more targeted and effective options. One of the most common and effective treatments for many types of cancer is radiotherapy treatment, also known as radiation treatment for cancer. This therapy uses high-energy radiation to target and destroy cancer cells, helping to shrink tumors and alleviate symptoms.

At Meridian Hospital, we believe in providing comprehensive care and information to our patients and their families. In this blog, we’ll explore the fundamentals of radiation oncology, how radiotherapy works, and what patients can expect from this critical cancer treatment.

1. What is Radiotherapy?

Radiotherapy, or radiation therapy, involves the use of high doses of radiation to kill or slow the growth of cancer cells. Unlike other treatments, such as surgery or chemotherapy, radiotherapy is often highly targeted, focusing only on the cancer cells while aiming to minimize harm to surrounding healthy tissue.

Types of Radiotherapy:

  • External Beam Radiotherapy (EBRT): The most common form, where a machine directs radiation precisely at the tumor from outside the body.
  • Internal Radiotherapy (Brachytherapy): This involves placing a radioactive source inside or near the tumor site, commonly used for cancers of the cervix, prostate, and breast.
  • VMAT (Volumetric Modulated Arc Therapy): VMAT is a highly advanced radiation technique that delivers a precise dose of radiation from different angles. It adjusts the intensity and shape of the radiation beams as they rotate around the patient, allowing for faster treatment with improved accuracy and reduced side effects.
  • 3DCRT (Three-Dimensional Conformal Radiation Therapy): 3DCRT uses detailed 3D imaging to map out the tumor’s location, enabling the radiation beams to conform to the shape of the tumor. This approach minimizes exposure to healthy tissue, making it effective for treating complex tumors.
  • 2DCRT (Two-Dimensional Conformal Radiation Therapy): 2DCRT is an older technique that uses flat, two-dimensional imaging to target the tumor with radiation. While less precise compared to 3DCRT or IMRT, it is still a viable option for treating certain types of cancers, offering simplicity and lower cost.
  • IMRT (Intensity-Modulated Radiation Therapy): IMRT allows for the modulation of radiation beam intensities to deliver high doses of radiation to a tumor while sparing surrounding healthy tissue. This precision makes IMRT ideal for treating tumors near critical structures, such as the brain or spinal cord.
  • IRT (Image-Guided Radiation Therapy): IRT combines imaging technology with radiation therapy to ensure that the radiation is delivered precisely to the tumor. By using real-time imaging, IRT can correct any movement of the tumor during treatment, improving accuracy and reducing side effects.
  • SRS (Stereotactic Radiosurgery): SRS is a non-invasive procedure that delivers high doses of focused radiation to small, well-defined tumors, often in the brain. It is used to treat conditions like brain tumors or arteriovenous malformations, offering a precise, targeted approach with minimal recovery time.

2. How Does Radiotherapy Work?

Cancer cells grow and divide at an abnormal rate, and radiotherapy targets these cells by damaging their DNA, preventing them from multiplying. Over time, this causes the cancer cells to die off while allowing healthy cells, which are less affected by the radiation, to recover.

Radiotherapy can be used in different ways depending on the patient’s condition and type of cancer:

  • Curative Treatment: Aims to completely destroy cancer cells, particularly effective in early-stage cancers.
  • Palliative Treatment: Helps relieve pain and symptoms when cancer has spread to other parts of the body.
  • Adjuvant Therapy: Used after surgery to eliminate any remaining cancer cells.
  • Neoadjuvant Therapy: Administered before surgery to shrink tumors, making surgery easier and more effective.

3. The Role of Radiation Oncology in Cancer Treatment

Radiation oncology is the field that specializes in treating cancer with radiation. Radiation oncologists are the doctors responsible for planning and administering radiotherapy treatment. At Meridian Hospital, our team of skilled radiation oncologists collaborates with medical oncologists, surgeons, and other specialists to create a tailored treatment plan for each patient.

4. What to Expect During Radiotherapy Treatment

Undergoing radiation treatment for cancer may sound intimidating, but understanding the process can help ease any anxieties. Here’s a general overview of what patients can expect:

  • Consultation and Planning: A radiation oncologist will conduct an initial consultation to understand the patient’s cancer type, stage, and overall health. Advanced imaging techniques, such as CT or MRI scans, are used to map out the exact location of the tumor.
  • Simulation: During the simulation session, patients are positioned for treatment, and markings or molds may be created to ensure that radiation is precisely targeted each time.
  • Treatment Sessions: Radiotherapy sessions typically last a few minutes each day and may be scheduled over several weeks. The exact length of treatment depends on factors like cancer type, size, and location.

Radiotherapy itself is painless, and patients can often return to their regular activities after each session. However, it’s essential to discuss any side effects with your radiation oncologist and manage them appropriately.

5. Common Side Effects of Radiotherapy

While radiotherapy is designed to minimize damage to healthy tissue, some side effects are possible. The type and severity of side effects vary depending on the treatment area and dosage. Common side effects may include:

  • Fatigue: One of the most common side effects, fatigue usually improves after treatment ends.
  • Skin Changes: Redness, irritation, or peeling may occur at the treatment site but typically resolves over time.
  • Digestive Issues: If the abdomen or pelvis is treated, patients may experience nausea, diarrhea, or appetite loss.
  • Hair Loss: Radiation to certain areas, such as the head, may cause hair loss in the treatment area.
