Radiation Oncology Q & A

What is radiation oncology?

Radiation oncology is a cancer treatment that uses high-energy beams to kill cancer cells in targeted locations. The energy beams only affect the area undergoing treatment, which is why radiation oncology is called a local therapy. 

Radiation oncology works by damaging the DNA in the cancer cell. That damage stops the replication of cancer cells, preventing further growth of the cancer. Ultimately, the damaged cancer cells die, and your body gets rid of them.

You need days or weeks of radiation therapy to damage enough of the cancer cells to stop further growth. And, the cancer cells continue to die weeks to months after you stop treatment.

What are the types of radiation oncology?

Arizona Center for Cancer Care is always looking for the best cancer treatments and technology available. They utilize many types of radiation oncology and continuously update their treatments as new therapies become available. The practice also actively participates in clinical trials to offer patients the most current treatments.

Types of radiation oncology include:


Brachytherapy is a type of internal radiation oncology. For this therapy, your board-certified radiation oncologist places radioactive beads or seeds in or near your cancerous tumor. 

The radioactive beads or seeds may remain in place for a few minutes (high-dose rate implants) or several days (low-dose rate implants).

Stereotactic radiosurgery (STRS)

With STRS, the oncologists use computers that pinpoint the location of your tumor and then deliver high doses of radiation directly at the tumor, limiting radiation exposure to the healthy surrounding tissue.

Why would I need radiation oncology?

Arizona Center for Cancer Care uses radiation oncology to treat cancerous tumors that are not surgically removable because of location or how the tumor interacts with vital organs.

The specialists also use radiation oncology following limited breast cancer surgery, also called breast-conserving surgery, to reduce the risk of relapse.

What can I expect during radiation oncology?

The radiation oncologists at Arizona Center for Cancer Care customize care to best meet your needs. They explain what you can expect during radiation oncology at your consultation.

Depending on the cancer type and treatment needs, you may need radiation therapy five days a week for 6-7 weeks. Treatments take 10-30 minutes. 

You may feel tired following radiation therapy. Other side effects depend on the type of cancer you have and where you’re getting the therapy.
