Radiation Therapy in Iran

radiation therapy in iran

What is radiation therapy, and how does it work ?

Tumors are made up of cells that are reproducing at abnormally high rates. Radiation therapy specifically acts against cells that are reproducing rapidly. Normal cells are programmed to stop reproducing (or dividing) when they come into contact with other cells. In the case of a tumor, this stop mechanism is missing, causing cells to continue to divide over and over. It is the DNA of the cell that makes it capable of reproducing.

Radiation therapy uses high energy x-rays to damage the DNA of cells, thereby killing the cancer cells, or at least stopping them from reproducing. Radiation also damages normal cells, but because normal cells are growing more slowly, they are better able to repair this radiation damage than are cancer cells.

In order to give normal cells time to heal and to reduce a patient's side effects, radiation treatments are typically given in small daily doses, five days a week, over a six-or seven-week period. It is estimated that more than 50% of cancer patients will receive radiation at some point during their treatment.

 

Radiotherapy treatment in Iran


What is radiotherapy treatment?

radiotherapy-treatmentRadiotherapy works by destroying cancer cells in the affected areas. Normal cells can also be damaged by radiotherapy, which may cause side effects. Cancer cells cannot repair themselves after radiotherapy but normal cells usually can.

The type of radiotherapy you’re given will depend on the type of cancer you are battling.

Goals of radiotherapy treatment

Curative treatment

Radiotherapy is normally given to try and destroy tumors and cure the cancer. It may also be used with other treatments such as surgery and chemotherapy.

Palliative

Doctors may give radiotherapy to help relieve the symptoms or side effects that you have, if it’s not possible to cure the cancer.

Radiation therapy types in iran

There are two main types of radiation therapy : -

external radiation therapy, where a beam of radiation is directed from outside the body, and internal radiation therapy, also called brachytherapy or implant therapy, where a source of radioactivity is surgically placed inside the body near the tumor.

1.External radiation in iran
External radiation may also be called x-ray therapy, cobalt therapy, proton therapy, or intensity modulated radiation therapy (IMRT). This type of radiation is administered using a machine called a linear accelerator. Treatment can be given once or twice a day, depending on the treatment protocol being used.

Treatments are given 5 days a week for several weeks, depending on the total final dose of radiation that is planned. Patients are given a break from treatment on weekend days to give normal cells some time to heal, thus reducing side effects. A person receiving external radiation therapy is not radioactive or dangerous to the people around him or her.

2.Internal radiation therapy in iran
Internal radiation therapy places the source of the high-energy rays inside the body, as close as possible to the cancer cells. This may be done by implanting "seeds" (small pieces of the radioactive substance) or by using an implanted reservoir, into which a liquid radioactive substance is injected. This delivers very intense radiation to a small area of the body and limits the dose to normal tissue. Internal radiation therapy allows the doctor to give a higher total dose of radiation in a shorter time than is possible with external treatments.

The radioactive substances used (also called the "radiation source") typically include radium, cesium, iodine, and phosphorus. Depending on the substance, the implant may be temporary or permanent, although the effect wears off over time in all cases. Depending on the type of radiation source, patients with radiation implants may need to be isolated from visitors for a period of time, so as not to expose others to radioactivity.

You've probably seen an X-ray of your teeth or some other part of your body. At high doses - many times greater than those used for X-ray exams - radiation can kill cancer cells and shrink tumors. More than half of all cancer patients receive some radiation therapy as part of their treatment.

What is the Cost of Radiation Therapy in Iran?


The cost of radiation therapy or any cancer treatment is an additional burden on anyone’s mind while thinking of getting the treatment, be it for yourself or a family member.


It is very important that the health and well-being of the patient is the first thing that influences the decision to choose radiation therapy and not the cost. In most cases taking a radiation therapy or any cancer treatment for that matter, is a necessity not an option.


For this, you need to go to the best radiation oncologists practicing in a renowned hospital. However, the cost of this varies from one city to another all around the world.

The cost of radiation therapy in Iran start from $140

Radiation therapy side effects

Radiation therapy damages healthy cells along with the cancer cells, and this damage can cause side effects. Most of the body's healthy cells recover after the therapy is stopped. The side effects you may get depend on your radiation dose and what body parts are treated.


Possible side effects include :

Tiredness (fatigue)
Hair loss on the treated body part
Skin irritation like a bad sunburn on the treated body part
Nausea, vomiting or diarrhea, if the abdomen is treated
Mouth sores, a sore throat or dry mouth, if the head or neck is treated

These side effects usually go away within a few weeks when the treatment is finished.

There can also be long-term side effects months or years after treatment. These side effects depend on your age, how much radiation you get and what body parts are treated


Possible long-term side effects include : -

Damage to the lungs or other organs
Infertility
Cataracts (caused by TBI)
Delays in growth and the ability to learn for some children
Risk of getting leukemia or other cancer years later (when given along with chemotherapy)

3What is the success rate of radiation therapy?
Men with localised prostate cancer who are treated with external-beam radiation therapy have a cure rate of 95.5% for intermediate-risk prostate cancer and 91.3% for high-risk prostate cancer. The 5-year survival rate using this treatment is 98.8% overall.
4How long is a session of radiotherapy?
External-beam radiation therapy delivers radiation from a machine outside the body. Each session is quick and painless, lasting about 15 minutes. Typically, people have treatment sessions 5 times per week, Monday through Friday. This schedule continues for 3 to 9 weeks.
5Can radiation cure cancer?
At high doses, radiation therapy kills cancer cells or slows their growth by damaging their DNA. Cancer cells whose DNA is damaged beyond repair stop dividing or die. When the damaged cells die, they are broken down and removed by the body. Radiation therapy does not kill cancer cells right away.
6Is it safe to be around someone receiving radiation therapy?
Some cancer patients who receive radiation therapy worry that their bodies will become “radioactive” after they receive radiation treatment. Their concern is that close physical contact with others could expose them to radiation. The general answer to this concern is that physical contact is fine.

Radiation therapy isn't painful, but some of the side effects it causes can be. For instance, if you are getting radiation to the head and neck area, you might have a sore throat, trouble swallowing, or mouth sores. These can hurt. ... Pain is not part of cancer treatment
8How long does it take to recover from radiation therapy?
Each radiation therapy treatment takes about 10 minutes. Radiation therapy to try and cure cancer is usually delivered daily, Monday through Friday, for about five to eight weeks. Weekend breaks allow normal cells to recover.
9How long does it take for radiation side effects to go away?
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.
10What is the survival rate of radiation therapy?
The median survival time of 580 patients with malignant disease treated during this period in 1988 was 12.4 months. 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%.
11How does radiation kill?
Ionizing radiation—the kind that minerals, atom bombs and nuclear reactors emit—does one main thing to the human body: it weakens and breaks up DNA, either damaging cells enough to kill them or causing them to mutate in ways that may eventually lead to cancer.
12Does radiation make you lose weight?
Appetite: While it is important to try not to lose weight during treatment, the side effects of radiation to certain areas of the body may make it difficult to eat and digest. ... Hair Loss: Radiation therapy can cause hair loss only in the area being treated.
13Why does radiotherapy make you so tired?
Fatigue is feeling tired physically, mentally, and emotionally. It's very common for people with cancer and often happens with radiation therapy. Most people start to feel tired after a few weeks of radiation therapy. This happens because radiation treatments destroy some healthy cells as well as the cancer cells
14How is radiation therapy done?
Radiation therapy can be given in 3 ways: External radiation (or external beam radiation): uses a machine that directs high-energy rays from outside the body into the tumor. ... It's done during outpatient visits to a hospital or treatment center. Internal radiation: Internal radiation is also called brachytherapy
15Do you lose your hair with radiotherapy?
Your doctor or nurse can tell you if your treatment is likely to affect your hair. ... Not all chemotherapy drugs make your hair fall out. Radiotherapy can cause your hair to fall out, but only in the area being treated. Hair does not always grow back after radiotherapy.
