Is radiation therapy considered chemotherapy?

Is radiation as effective as chemotherapy?

The radiation beams change the DNA makeup of the tumor, causing it to shrink or die. This type of cancer treatment has fewer side effects than chemotherapy since it only targets one area of the body.

What comes first chemo or radiation?

Giving Chemo and Radiation Therapy at Same Time Offers Same Benefits as Sequential Timing. If early-stage breast cancer is going to be treated with both chemotherapy and external beam radiation therapy, chemotherapy usually is given first. Radiation generally starts after chemotherapy is done.

Can you have radiotherapy without chemotherapy?

You may have radiotherapy on its own, or you may have it combined with chemotherapy (chemoradiation). For some types of cancer, you have radiotherapy after surgery (adjuvant radiotherapy), to lower the risk of it coming back.

Does a radiation oncologist do chemotherapy?

Medical oncologists treat cancer using medication, including chemotherapy, immunotherapy, and targeted therapy. Radiation oncologists treat cancer using radiation therapy, which is the use of high-energy x-rays or other particles to destroy cancer cells.

What happens if I refuse radiation treatment?

Patients who refuse recommended adjuvant radiation therapy have unacceptably high rates of local recurrence. Omission of radiation for advanced age alone is associated with local recurrence rates comparable to those for younger patients.

How long does it take radiation to shrink a tumor?

For tumors that divide slowly, the mass may shrink over a long, extended period after radiation stops. The median time for a prostate cancer to shrink is about 18 months (some quicker, some slower).

How long does it take to heal after radiation therapy?

Most side effects generally go away within a few weeks to 2 months of finishing treatment. But some side effects may continue after treatment is over because it takes time for healthy cells to recover from the effects of radiation therapy. Late side effects can happen months or years after treatment.

What is the cost of one radiation treatment?

The cost of radiation therapy was estimated from Medicare reimbursements. The median cost for a course of radiation therapy per patient was $8600 (interquartile range [IQR], $7300 to $10300) for breast cancer, $9000 (IQR, $7500 to $11,100) for lung cancer, and $18,000 (IQR, $11,300 to $25,500) for prostate cancer.
