The purpose of radiation therapy is to induce damage to cancer cells; however, it also has the potential to cause damage to healthy cells in the treatment region. Side effects result from damage to healthy cells. What part of the body is subjected to radiation therapy determines the severity of the side effects that may be experienced. When exposed to radiation, various cells and tissues in the body deal with it in a variety of ways.

When it comes to radiation therapy, cells that divide at a rapid rate are typically the ones that are harmed the most. Cells that are found in the bone marrow, cells that line the mouth and gastrointestinal tract, and cells that line the skin are all examples of these. Any time during, soon after, or within a couple of days or weeks to two months after treatment has been completed, the side effects may manifest themselves.

Due to the fact that it takes time for healthy cells to recover from the effects of radiation therapy, although some radiation side effects may linger after treatment has been completed, this is not guaranteed. Bear in mind that it takes some time for healthy cells to recover from the effects of radiation therapy being administered to them.

After treatment, late radiation side effects can manifest themselves months or even years later. The ability of certain cells to heal themselves may be compromised if the dosages of radiation are high enough. Because of this, certain adverse effects have a tendency to persist for a considerable amount of time or to be permanent.

The type of radiation therapy, the part of your body that is being treated, the amount of radiation therapy, the treatment schedule, and your overall health will all affect the side effects of radiation. The most common radiation side effects is fatigue. In most cases, it occurs after a few weeks of radiation therapy, and it has the potential to become more severe as the treatment continues.

Due to the fact that the radiation travels through the skin in order to reach the designated location for treatment, skin issues are also a common occurrence with external radiation therapy. Dryness or itching of the skin may develop in the area that has been radiated. It may change red, become darker, or appear tanned from time to time.

Only the area that is being treated with radiation therapy may experience hair loss or thinning of the hair from the treatment. Both the amount of hair loss and the amount of hair that grows back tend to vary from person to person and are dependent on the amount of radiation that is received. Approximately two to three weeks following the beginning of radiation therapy, hair loss may begin.

Hair loss is typically brought on by lower doses of radiation. It is more common for higher doses to cause permanent hair loss. The color or texture of the hair may change as it regrows, which typically occurs between three and six months after radiation therapy has been completed. Additionally, the hair may grow back thinner or spotty.
