The Basics of Radiation Therapy for Cancer That You Should Know

Share

One of the prevalent therapies used in the treatment of cancer is radiation. Irradiation, x-ray therapy, radiotherapy, and radiation therapy are all different names for the same thing: radiation treatment.

Let’s start with understanding what radiation therapy is. In cancer radiation treatment, high-energy particles or waves kill or harm cancer cells. These high-energy particles or waves include x-rays, gamma rays, electron beams, and protons. It is natural for your cells to divide to produce new ones continually. However, cancer cells multiply and divide more quickly than most normal cells. 

Inside cells, radiation may cause damage by creating micro cracks in the DNA. These fractures prevent cancer cell growth and division, ultimately leading to the cancer cells’ death. Radiation may also damage normal cells in the vicinity, although most of these cells can heal and return to functioning normally.

  • Radiation can shrink tumors for easier surgery.
  • Stereotactic radiosurgery delivers radiation in one session.
  • Radiation can enhance the effects of immunotherapy.
  • Fractionation splits radiation doses to reduce side effects.
  • MRI-guided radiation improves treatment accuracy.
  • Radiation also treats non-cancerous conditions.
  • Skin tattoos help with consistent radiation targeting.

How Radiation Therapy Is Different From Others?

Radiation therapy is often used as a local treatment. Still, chemotherapy and other cancer-fighting therapies administered via the mouth or through injection typically expose the body to cancer-fighting medications. This shows that it is often targeted at and only affects the specific area of the body that requires therapy. The radiation treatments are carefully calibrated to kill cancer cells while causing as minor damage as possible to the healthy cells that are located nearby.

Types Of Radiation Therapy

Some types of radiation therapy, known as systemic radiation therapy, include administering radioactive chemicals either orally or intravenously. Even though this radiation can move freely across the body, the radioactive material concentrates in the vicinity of the tumour. As a result, the rest of the body experiences just a tiny amount of after effects.

Who Undergoes Treatment With Radiation Therapy?

Some types of radiation therapy, known as systemic radiation therapy, include administering radioactive chemicals either orally or intravenously. Even though this radiation can move freely across the body, the radioactive material concentrates in the vicinity of the tumour. As a result, the rest of the body experiences just a tiny amount of after effects.

Who Undergoes Treatment With Radiation Therapy?

Radiation treatment is administered to more than half of all cancer patients. Radiation therapy is not always combined with other forms of treatment for cancer. Sometimes, it is the only cancer treatment that is required. The choice of whether to employ radiation treatment includes some factors. This comprises the type and level of cancer and any other health issues the patient may have.

Radiation Therapy Is Curing Or Controlling Early-Stage Cancer

Radiation may be pretty effective in treating some malignancies. In certain instances, radiation therapy may treat cancer and cause it to either recede or disappear entirely. Chemotherapy or other forms of anti-cancer medication may be used first sometimes. 

In the case of various types of cancer, radiation treatment may be administered before surgery to reduce the size of the tumour. This procedure is referred to as pre-operative therapy or neoadjuvant therapy. It could also be done after surgery to prevent the disease from returning. Here it is called adjuvant therapy.

Radiation Therapy As A Less Harmful Therapy

Radiation therapy may be the chosen treatment method for some types of cancer that may be treated either by radiation therapy or surgery. This is because radiation has the potential to do less harm, and the affected area of the body may have a greater chance of generally functioning following treatment.

Radiation Therapy In Combination With Different Therapies

It is possible to treat some forms of cancer using a combination of radiation treatment, chemotherapy, or perhaps other sorts of anti-cancer medications. Radiosensitizers are medications that make cancer cells more susceptible to radiation’s effects, which makes radiation therapy more effective. 

When treating some forms of cancer with radiation and anti-cancer medications simultaneously, research has shown that they may assist each other’s function even better than if given alone. This is because the two treatments complement one another. One drawback is that the adverse effects of the medications are more severe when they are taken simultaneously.

Radiation Therapy To Prevent The Cancer From Returning (Recurring) In Another Location

Cancer can spread from the original site to other areas of the body. Even if imaging examinations such as CT scans or MRIs do not reveal any metastatic cancer cells, medical professionals often work under the assumption that some cancer cells may have already spread. 

Radiation therapy may be used in certain instances to treat the region where the cancer is most likely to spread to eliminate cancer cells before they develop into tumors. Radiation therapy to treat current cancer may sometimes be combined with radiation therapy to prevent future cancers. This is particularly effective when the region where cancer may spread is near the tumour.

Radiation Therapy To Alleviate The Symptoms That Advanced Cancer Causes

There are some instances in which cancer has progressed to a point where it cannot be treated. However, certain tumours could still be managed to make them smaller and improve the patient’s overall quality of life. Radiation treatment has the potential to alleviate some of the symptoms that might be caused by advanced cancer, including discomfort, difficulty eating or breathing, and obstructions in the bowels. This kind of radiation therapy is known as palliative radiation.

Radiation Therapy To Treat Cancer That Has Come Back (Recurred)

Radiation therapy may treat cancer or the symptoms produced by advanced cancer in a patient whose cancer has reappeared (recurred) after being treated. The decision to treat a recurrence with radiation relies on a variety of different circumstances. For instance, if cancer has returned in a section of the body previously treated with radiation, likely that more radiation therapy cannot be administered in the exact location. 

It depends on the total quantity of radiation administered in the past. In other cases, the radiation treatment may be administered to a different or the same body part. Because some cancers may not react as well to radiation, it is possible that radiation therapy will not be used even if the tumors return.

How Does One Get Radiation Therapy?

There are three different techniques to provide radiation therapy:

Treatment with External Radiation

Treatment with external radiation, also known as external beam radiation, involves using a machine that targets the tumor with high-energy rays originating from outside the body. Outpatient visits to a healthcare facility or treatment center are required for this procedure. It is often administered over many weeks, and occasionally, it may be administered twice daily for several weeks.

 A person exposed to radiation from the outside is not radioactive and does not need to take any further safety measures in their own house.

Brachytherapy

Radiation administered from inside the body is sometimes referred to as brachytherapy. The radioactive source is implanted within the body directly into the tumor or near it. Radiation might be sent into the body and left to do its job with some forms of brachytherapy. 

Sometimes it is inserted into the body for a certain amount before being taken out again. This is determined by the sort of cancer that the patient has. Specific safety measures are required for an extended time when exposed to this kind of radiation. However, it is essential to know that if the internal radiation is still present in the body after some time has passed, it will ultimately cease to be radioactive.

Systemic radiation

Systemic radiation refers to the use of radioactive medications in the treatment of some forms of cancer. These drugs may either be taken orally or injected intravenously. After that, these substances are distributed throughout the body. After receiving these medications, you may be required to take additional safety measures while you are at home for a certain length of time.

Does Cancer Develop As A Result Of Radiation Therapy?

It has been known for a long time that radiation treatment is associated with a somewhat increased chance of developing another cancer. When determining the appropriate course of action for a patient, medical professionals have to consider the potential advantages and dangers of each treatment option. 

The likelihood of developing secondary cancer due to these therapies is very low and is exceeded by the benefits of successfully treating the first cancer. There is still a possibility of doing so. One of the numerous reasons every case is unique and why every individual has to be involved in determining the appropriate therapy for them is because of this. The danger varies greatly depending on the location in the body where the radiation therapy will be administered.

Does Treatment With Radiation Impact A Woman’s Ability To Get Pregnant Or Her Fertility?

It is essential to avoid becoming pregnant while undergoing radiation treatment since the radiation may cause damage to the developing fetus. Be careful to discuss the various birth control methods with your healthcare provider if there is even a remote possibility that you may get pregnant. Notify your physician as soon as possible if you think you could be pregnant or if you already are pregnant.

Suppose the part of your body receiving radiation treatment also contains your ovaries. In that case, there is a chance that the dosage of radiation you receive might render your ovaries inoperable (also known as sterility). This means that you would be unable to produce children. Before beginning radiation treatment, it is essential to understand the risks associated with this option thoroughly.

Does Treatment With Radiation Impact A Man’s Fertility?

It is unknown to what extent radiation will affect the fertility of a man’s future offspring if he is undergoing radiation treatment simultaneously. Because of this, medical professionals often urge men to refrain from sexual activity with their partners throughout therapy and for several weeks afterwards. 

If the region receiving radiation treatment involves the testicles, there is a chance that the amount of radiation might cause the testicles to stop functioning correctly, which would result in sterility and an inability to produce children for the patient. 

Before beginning radiation treatment, it is essential to understand the risks associated with this option thoroughly. There has not been a sufficient study done to determine how sperm that has been exposed to radiation would influence the offspring that will be produced from that sperm.

Takeaway

The cancer you have and the tumor’s location has a role in determining the sort of radiation treatment you could get. There are various instances in which more than one type is used. Your cancer care team should be able to address any particular concerns you have about the sort of radiation treatment that has been ordered for you, how it will impact your body, and any precautions that may be necessary.

Suppose your cancer care team suggests radiation therapy as a treatment option for you. In that case, they think the advantages you will get from it will be more significant than the potential adverse effects. Despite this, the choice is ultimately yours to make. Radiation therapy may be the best treatment option for you, but only if you are fully informed about all of its potential advantages and hazards.
