Your body then is naturally able to get rid of these damaged cancer cells. Radiation therapy also affects normal cells. However, your normal cells are able to repair themselves in a way that cancer cells cannot. During external beam radiation, a treatment machine will aim beams of radiation directly to the tumor.
How long does it take to recover from radiation treatment?

How long does it take for a tumor to shrink after radiation?
At the same time, if a cell doesn't divide, it also cannot grow and spread. 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 does radiation therapy work step by step?
Overall, there are five basic steps of radiation therapy that we can share to give patients an idea of what to expect. These steps include initial consultation, simulation, treatment planning, treatment delivery and post treatment follow-up. Consultation is the first step of the radiation therapy process.
At what stage of cancer is radiotherapy used?
Radiotherapy may be used in the early stages of cancer or after it has started to spread. It can be used to: try to cure the cancer completely (curative radiotherapy) make other treatments more effective – for example, it can be combined with chemotherapy or used before surgery (neo-adjuvant radiotherapy)
Do tumors grow back after radiation?
Normal cells close to the cancer can also become damaged by radiation, but most recover and go back to working normally. If radiotherapy doesn't kill all of the cancer cells, they will regrow at some point in the future.
Is radiation worse than chemo?
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.
Does radiation always shrink tumors?
Radiation therapy is always a balance between destroying the cancer cells and minimizing damage to the normal cells. Radiation doesn't always kill cancer cells or normal cells right away. It might take days or even weeks of treatment for cells to start dying, and they may keep dying off for months after treatment ends.
Is radiation treatment painful?

Why is radiation treatment important?
When radiation treatments are given for cancer, special care is taken to spare as much normal tissue as possible from radiation exposure. The radiation dose is carefully measured and aimed at the tumor to kill as many cancer cells with as little damage to normal tissue as possible.
Why are cancer cells more likely to be damaged by radiation?
Cells that are growing and multiplying are very sensitive to the effects of radiation. Because cancer cells reproduce more frequently than normal cells, they are more likely to be damaged by radiation. Normal cells can also be affected by radiation, but normal cells tend to be able to recover from radiation damage. YouTube.
What is external beam radiation?
external beam: an external beam radiation therapy machine outside your body aims the radiation at your cancer cells. internal or brachytherapy: Sometimes this type of radiation therapy is also called liquid radiation, because the radiation is placed inside your body, near the cancer cells.

What is the purpose of radiation therapy?
Radiation Therapy (irradiation or radiotherapy) is the use of high energy radiation, primarily x-rays, to kill cancer cells. In high doses, radiation causes damage to cells by interfering with the cell’s ability to grow and reproduce. Cells that are growing and multiplying are very sensitive to the effects of radiation.
When is radiation given?
When radiation is combined with surgery, the radiation treatments may be given before or after surgery. When it is done before surgery it is used to shrink the size of a tumor to make removal easier.
