Understanding How Radiation Therapy Works

Many patients going through radiation therapy don’t truly understand how their tumors are shrunk or the cancer cells killed.  It is a complex procedure that many physicians are not able to simplify for patience just learning they have cancer.  It is a term that is commonly tossed out in the treatment plan of various cancers; it is crucial that individuals understand exactly what the treatment they are being prescribed will look like.  In this ongoing series on radiation therapy we will continue to look into the answers to questions many patients and loves ones are asking.

How does radiation kill cancer cells and shrink tumors using various radiation therapy and different techniques?

In radiation therapy the actual DNA of the cancer cells and tumors is damaged.  DNA refers the combination of unique molecules each of us is made from.  The molecules are carried within the cells.  The cells are actually carrying the genetic information, or molecules, that we pass between generations.  Individuals are created from a combination of cells that carry the molecules that carry our unique database of genetics; this genetic database is what radiation therapy is in charge of destroying.

This can occur in two different ways.  Radiation therapy can damage DNA directly thus creating a cell that can no longer repair itself or divide leading to the death of the cell.  Once the cell is damaged and dies it is then broken down into the body and naturally eliminated.

How does radiation therapy only kill those cells that are cancerous?

It doesn’t; that is the most truthful answer when someone asks how radiation therapy knows only to damage the cancerous cells.  In truth healthy normal cells can be damaged which leads to unpleasant side effects.  When planning for treatment the damage that can potentially be done to healthy cells is accounted for.

There is a certain amount of radiation that normal, healthy tissue can safely receive before any real side effects are reported.  Each part of the body is different and therefor a different treatment is used as called for.  External radiation using linear accelerator equipment may be used for more sensitive areas where as internal radiation, brachytherapy, is used on areas where tissue is hardier.  Knowing this information allows doctors to specifically target radiation throughout therapy.

From here our next installment will take a deeper look into why doctors chose to use radiation therapy over other treatments for cancer as well as how a plan is individualized to each specific patient.  As in treatment options of many diseases there is not a one size fits all treatment plan for cancer.  Linear accelerator equipment treating cancer through external radiation may work well with patients of a certain age with certain cancers where it would be ineffective for others.  Our next installment will further look into the answers to why and how questions in radiation therapy.

Treating Cancer Using Radiation Therapy Explained

There are many articles that talk about cancer and treatments for cancers.  Many are written in terms that the average person can’t fully comprehend.  This series of articles will discuss radiation therapy and how it is used to treat cancer.  It is difficult to get a cancer diagnosis for you or someone you love only to find that one of the main treatment options needs a medical degree to understand.  That is where articles like this help.

When treating cancer a term that is often used is radiation.  Many people will ask if the patient will be going through chemotherapy, radiation or a combination.  The problem is that the answer that is given is usually a combination or radiation alone but the reality is the patient hardly understands what that means.  Cancer treatments deserve to be spoken about in terms that all patients can understand and explain to their loved ones.

What exactly is radiation therapy?

In order to fully understand radiation therapy it is important to grasp exactly what radiation is.  There are two main definitions of radiation both which apply when discussing radiation therapy.

1)      Radiation is the discharge of energy in waves or the travel of subatomic particles, particles even smaller than an atom itself.  Most often radiation is used to describe ionization, generally speaking the process that an atom takes to form ions.  An ion is an atom that has either a positive or negative charge.  Positive ions are bad and negative ions are good.

2)      Radiation is also used to convey discharge outward from one central location.

In radiation therapy there are multiple types of radiation that can be used to shrink tumors and kill cancerous cells: x-rays, gamma rays and charged (negatively) particles.  High amounts of radiation in any of the three forms is delivered in treatment.

The process of radiation therapy occurs in one of two different methods.  The first method of radiation delivery is with the use of a machine such as a linear accelerator.  A linacs machine delivers radiation outside of the body.  This is known as external (outside) beam radiation therapy; literally a beam of radiation is sent through to the inside of your body.

The second method in which radiation can be delivered through sealed radioactive material that is placed close to the cancerous cells within the body.  This is often referred to as internal radiation therapy or brachytherapy.

Another form of radiation therapy is systemic radiation therapy which distributes radioactive substances that travels through the blood to kill cancerous cells.

If you or a loved one has been diagnosed with cancer there is a good chance that you will require some form of radiation therapy; in fact fifty percent of cancer patients do receive radiation therapy at one point or another during their treatment plan.  Not all radiation therapy uses linear accelerator equipment in delivery.  There are multiple methods of distributing radiation to shrink tumors and kill cancer cells.

We will further our discussion on radiation therapy for cancer treatments in out next installment.  Patience experiencing radiation therapy deserve to understand in greater detail the treatment they are receiving.
