Is radiation therapy painful?

No. Radiation is an x-ray which is invisible and painless. It's side effects depending on where and what organs are being treated could lead to discomfort or pain.
No. Radiation therapy is essentially a high energy x-ray. So just like getting a ct scan is not painful getting radiation therapy is also not painful.
Not directly. One cannot feel radiation upon exposure since it is very penetrating electromagnetive waves of energy and you will not know that you are exposed. However, the side effects of radiation particularly inflammation and swelling can cause pain but that's indirect result from radiation.
A quibble? The radiation is odorless, tasteless and invisible, and enters and exits matter without causing pain in creastures that can feel it, but reactions of body linings (mucosa) and skin can be harsh and severe enough to cause pain and suffering. Head and neck cancer is common, but some breast cancer ski reactions can be quite unpleasant for short periods. We have things to help.
Generally no. Photon and particle therapy beams cannot be felt. What can hurt is if the tissue being treated gets damaged - sometimes even the worlds finest radiation doctor cannot prevent this given patient genetics. When a tumor dies, it can swell. Stretching tissue can really cause pain. If skill or other tissue gets damages (nerves), it can feel painful often days later. In general it does not hurt.

No. Radiation itself is not painful but can have side effects such as tiredness, skin irritation, cough, shortness of breath and low blood counts. Read more...
Possibly. Radiation is painless during the treatments. If the esophagus is in the treatment fields it can cause a painful condition called esophagitis about 3 weeks into the treatment. This is worse when a patient also takes chemotherapy. There are medicines that help this discomfort and when treatment is done it should resolve. Read more...
Possibly. It depends on what tissues are treated by the path of the beam. By itself, it is not painful. But, it can interact with tissue over time to cause irritation. The esophagus is the first thing one can cause irritation with that is significant: so swallowing can hurt. This is an organ thereofore we try to avoid. Skin too can be affected, but more with protons than photons. Each case is unique. Read more...

What is radiation therapy?

Kill cancer by Rads. Use of high energy x-ray typically ( protons, gamma rays etc to name a few other) to cause irreparable damage to a target tumor to destroy the tumor while causing minimal damage to surrounding organs and tissues. Read more...
High powered xrays. High powered x-ray beam is directed towards your cancer to kill it. The machines are quite sophisticated so that they deliver the beam to the tumor without destroying a lot of normal tissue. Read more...

What is radiation therapy useful for?

Many things. Radiation therapy is used to decrease the risk of recurrence in breast cancer; it has treatment value in many other cancers including rectal, prostate, head and neck, lung and pancreatic cancers. In addition, it is useful for decreasing pain in cancer which has spread to bone. Lastly, it helps in disease which has traveled to the brain or skin. More uses available but space limited!

To cure some. Cancers (vocal cord, cervix, prostate etc), preserve organs and their functions (sarcoma, h&n, breast, rectums), partner with other treatments to improve risk or prevent recurrence (lymphoma, lung cancer, prophylactic cranial irradiation in small cell).

Radiation therapy. Is the use of x-rays to treat cancer. Radiation works by damaging the dna of dividing cells. Since cancer is uncontrolled cell growth, radiation is more effective on cancer cells than normal cells. Radiation has been used for cancer treatment since the late 1800s. It's use depends on cancer location, type, and stage. Unlike chemotherapy, it is a local treatment that only effects the area treated. Read more...

Your question is. Impossibly broad. Radiation effects normal tissue function passaged by entry and exit beams, but these vary with the disease treated, region of the body, dose/treatment, total dose, area/volume treated. If the organ is not in the treatment field, it will not be affected. Read more...
