How Radiation Affects Your Body. Radiation can damage the DNA in our cells. High doses of radiation can cause
Radiation not only kills or slows the growth of cancer cells, it can also affect nearby healthy cells. Damage to healthy cells can cause side effects. Many people who get radiation therapy have fatigue. Fatigue is feeling exhausted and worn out.
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.
Radiation therapy usually does not have an immediate effect, and it could take days, weeks or months to see any change in the cancer. The cancer cells may keep dying for weeks or months after the end of treatment. It may be some time before you know whether the radiation therapy has controlled the cancer.
Does Radiation Oncology Have Fewer Side Effects Compared to Chemotherapy? Radiation oncology and chemotherapy are both effective cancer treatments; however, they are different in many ways. Radiation oncology is localized: it targets only the affected area of the body, and therefore, tends to have fewer side effects.
Long term effects on tissue
Doctors call this radiation fibrosis. How this affects you will vary depending on which part of your body was treated. Fibrosis may cause any of the following: your bladder could become less stretchy and hold less urine after treatment to your abdomen, so you need to pass urine more often.
Avoid raw vegetables and fruits, and other hard, dry foods such as chips or pretzels. It's also best to avoid salty, spicy or acidic foods if you are experiencing these symptoms. Your care team can recommend nutrient-based oral care solutions if you are experiencing mucositis or mouth sores caused by cancer treatment.
The life expectancy of men who received radiation treatment was 11.49 (95% CI 10.72–13.18) years at age 75, and 10.56 (95% CI 9.79–11.58) years at age 80. Life expectancy was less than 10 years for men older than 80 years, reaching 9.46 (95% CI 7.73–11.44) years at age 82.
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.
Exposure to above-normal levels of radiation can lead to fatigue, nausea and vomiting, and changes in the blood. Exposure to very large does of radiation can lead to radiation sickness, with symptoms such as loss of appetite, hair loss, diarrhea, or even death within a few days or months.
Radiation sickness occurs when high-energy radiation damages or destroys certain cells in your body. Regions of the body most vulnerable to high-energy radiation are cells in the lining of your intestinal tract, including your stomach, and the blood cell-producing cells of bone marrow.
More than 60% of NPC patients receiving curative-intent radiotherapy suffered from a weight loss greater than 5% during the treatment [8], [9].
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.
There is usually no pain associated with radiation treatments. Also, nothing will touch you while you are receiving your treatments. You will likely hear clicking or beeping noises throughout the treatment, this is normal. You will not feel anything during your treatment if you are receiving external beam radiation.
A team led by scientists at Massachusetts General Hospital (MGH) recently found that the skin produces the hormone β-endorphin in response to radiation therapy, and that elevated β-endorphin levels contribute to fatigue after treatment.
Radiotherapy to relieve symptoms is also known as palliative radiotherapy. Palliative radiotherapy aims to shrink cancer, slow down its growth or control symptoms. It doesn't aim to cure cancer. Depending on the type of cancer you have, and where it has spread to, you might have external or internal radiotherapy.
The overall 5-year survival rate was 27%. For 105 patients treated definitively with radiation therapy, the median and 5-year survival rate figures were 26.0 months and 40%. For 149 patients treated with adjuvant radiation therapy, the 5-year survival rate was 62% (median survival rate not reached).
Radiotherapy can sometimes cause: a sore mouth. loss of appetite and weight loss.
With internal radiation, you may need to avoid touching the patient until the implant is removed or limit the time you spend very close to them. With systemic radiation therapy, you may also have to avoid the person's bodily fluids for a few days after treatment.
Some people who receive radiation therapy experience dryness, itching, blistering, or peeling on the skin in the area being treated. Skin changes from radiation therapy usually go away a few weeks after treatment ends. If skin damage becomes a serious problem, your doctor may change your treatment plan.
They concluded that “Median life expectancy decreased with increasing radiation dose at a rate of about 1·3 years per Gy, but declined more rapidly at high doses.
On the other hand, radiation therapy, immunotherapy, and chemotherapy, either alone or in combination can lead to short-term (temporary) immune system damage because they affect immune system blood cells for a fairly short period of time.
