The most common early side effects are fatigue (feeling tired) and skin changes. Other early side effects usually are related to the area being treated, such as hair loss and mouth problems when radiation treatment is given to this area. Late side effects can take months or even years to develop.
Reactions to radiation therapy often start during the second or third week of treatment. Or, they may last for several weeks after the final treatment. Some side effects may be long term. Talk with your treatment team about what you can expect.
Many people who get radiation therapy have fatigue. Fatigue is feeling exhausted and worn out. It can happen all at once or come on slowly. People feel fatigue in different ways and you may feel more or less fatigue than someone else who is getting the same amount of radiation therapy to the same part of the body.
As a result of these epidemiological studies, it was found that the mammary gland, skin, and colon, etc. are tissues and organs that are easily affected by radiation and develop cancer.
Radiation can damage the DNA in our cells. High doses of radiation can cause Acute Radiation Syndrome (ARS) or Cutaneous Radiation Injuries (CRI). High doses of radiation could also lead to cancer later in life.
Most side effects go away within 1–2 months after you have finished radiation therapy.
You may feel sick (nauseated), with or without vomiting, for several hours after each treatment. Your radiation oncologist may prescribe medicine (antiemetic) to take at home before and after each session to prevent nausea.
Don't wear tight clothing over the treatment area. It's important not to rub, scrub or scratch any sensitive spots. Also avoid putting anything that is very hot or very cold—such as heating pads or ice packs—on your treated skin.
Even though most radiation treatments only target specific collections of cancer cells, the effects of radiation can easily spread to nearby cells. Most recover within a few weeks, but some injuries develop later or require a longer recovery process.
The radiation stays in the body for anywhere from a few minutes to a few days. Most people receive internal radiation therapy for just a few minutes. Sometimes, internal radiation therapy can be given for more time. If so, they stay in a private room to limit other people's exposure to radiation.
Some cancers are difficult to treat and have high rates of recurrence. Glioblastoma, for example, recurs in nearly all patients, despite treatment. The rate of recurrence among patients with ovarian cancer is also high at 85%.
The most common early side effects are fatigue (feeling tired) and skin changes. Other early side effects usually are related to the area being treated, such as hair loss and mouth problems when radiation treatment is given to this area. Late side effects can take months or even years to develop.
The side effects of radiotherapy usually peak up to two weeks after treatment has finished. The effects of radiotherapy continue developing, and it may take a further couple of weeks to several months for you to feel normal, depending on the area of the body that has been treated.
Feeling very tired and lacking energy (fatigue) for day-to-day activities is the most common side effect of radiation therapy to any area of the body. During treatment, your body uses a lot of energy dealing with the effects of radiation on normal cells.
People having radiotherapy for brain tumours often feel tired. This can be worse if you're also taking steroids. The tiredness often reaches its maximum 1 to 2 weeks after the end of treatment.
Radiation therapy to the head and neck can cause side effects that make it difficult to take in adequate amounts of food and fluids. These side effects include loss of appetite, changes in taste or loss of taste, painful chewing and swallowing, mouth sores, dry mouth and nausea.
Radiation therapy involves giving high doses of radiation beams directly into a tumor. 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.
Sometimes radiotherapy to the chest can cause you to feel and be sick (nausea and vomiting). This is because the treatment area might include part of the stomach. And radiotherapy to the stomach can cause nausea and vomiting.
When it comes to early stages of disease, patients very frequently do well with either brachytherapy or external beam radiation. Success rates of around 90% or higher can be achieved with either approach.
Radiation does not hurt, sting, or burn when it enters the body. You will hear clicking or buzzing throughout the treatment and there may be a smell from the machine.
ALARA means avoiding exposure to radiation that does not have a direct benefit to you, even if the dose is small. To do this, you can use three basic protective measures in radiation safety: time, distance, and shielding.
Today, radiation is a common and valuable tool in medicine, research and industry. It is used in medicine to diagnose illnesses, and in high doses, to treat diseases such as cancer. Also, high doses of radiation are used to kill harmful bacteria in food and to extend the shelf life of fresh produce.
