Radiation Therapy Fundamentals for Cancer Treatment

We use radiation therapy to fight cancer, focusing on tumors. It’s a key treatment that kills cancer cells without harming healthy tissue too much.

Studies show radiation therapy works for many cancers. It uses high-energy particles or waves to kill cancer cells. It can be used alone or with surgery and chemotherapy.

External Beam Radiation Therapy Techniques

External beam radiation therapy (EBRT) uses a machine outside the body. It sends beams to the tumor site. This method targets tumors well, protecting healthy tissues.

EBRT has different types, like 3D conformal and intensity-modulated radiation therapy (IMRT). Each type is chosen based on the tumor’s size and location.

Internal Radiation Therapy: Brachytherapy Applications

Brachytherapy puts a radioactive source inside or near the tumor. It delivers high doses of radiation to the tumor, protecting healthy tissues.

Brachytherapy can be temporary or permanent. Temporary brachytherapy uses a radioactive material for a short time before it’s removed. Permanent brachytherapy leaves the material in the body, which loses radioactivity over time.

Systemic Radiation Therapy for Widespread Cancer

Systemic radiation therapy uses radioactive substances that travel through the body. It targets cancer cells. This method is used for cancers that have spread.

It’s effective for some cancers, like thyroid cancer. It’s used when other treatments aren’t possible.

The benefits of IGRT are:

1. Enhanced accuracy in radiation delivery
2. Reduced margins around the tumor, sparing more healthy tissue
3. Ability to adapt treatment plans in response to changes in tumor size or position

IGRT is great for tumors that move or change during treatment. This includes those in the lung or prostate.

Stereotactic Radiosurgery for Brain and Body Tumors

Stereotactic radiosurgery (SRS) is a precise radiation therapy. It gives a high dose of radiation to a specific area. It’s called “surgery,” but it’s non-invasive and doesn’t require an incision.

SRS is used to treat:

• Tumors in the brain, including metastases and certain benign lesions
• Small tumors in other parts of the body, such as the lung, liver, and spine

The precision of SRS means it can treat tumors effectively. It does so with minimal damage to surrounding tissues. This makes it a good option for patients with tumors that can’t be removed surgically or are hard to reach.

These advanced radiation treatment technologies have greatly improved cancer care. As research and technology keep advancing, we can expect even more innovative radiation therapy methods in the future.
