The primary objective of radiation therapy is to inflict damage on cancer cells; however, it also has the potential to inflict damage on benign cells in the treatment area. Unintended side effects are caused by damage to healthy cells. The extent to which side effects may be experienced is contingent upon the specific body part that is placed under radiation therapy. Various cells and tissues in the body respond to radiation in a variety of ways.
The most significant effect of radiation therapy is typically observed in cells that divide rapidly. These are composed of cells that line the skin, cells that line the mouth and gastrointestinal tract, and cells that are present in the bone marrow. Any side effects may manifest themselves during, immediately after, or within a few days or time weeks of treatment completion.
Despite the fact that some radiation side effects may persist after treatment has been concluded, this is not a guarantee, as it takes time for healthy cells to recover from the effects of radiation therapy. The recovery of the effects of radiation therapy on healthy cells necessitates a specific period of time. It is imperative to keep this in mind.
Late radiation side effects may manifest months or even years after treatment. The capacity of specific cells to self-heal may be jeopardized if the radiation dosages are excessive. As a result, certain adverse side effects are more likely to persist for an extended period of time or to become permanent.
The side effects of radiation are contingent upon the type of radiation therapy, the body part being treated, the quantity of radiation therapy, the treatment schedule, and your overall health. Fatigue is one of the most common radiation side effects. It typically becomes apparent after a few weeks of radiation therapy and has the potential to deteriorate as the treatment progresses.
Skin complications are not uncommon in external radiation therapy, as the radiation must travel through the skin to reach the intended treatment site. The region that has been exposed to radiation may exhibit dryness or irritation of the skin. It may at times appear tanned, darken, or change color to a ruddy hue.
The treatment may result in hair loss or hair reduction exclusively in the area that is being treated with radiation therapy. The quantity of hair that regrowth and the extent of hair loss will differ from person to person, as they are dependent on the amount of radiation exposure. Radiation therapy may cause hair loss following two to three weeks of treatment.
Reduced radiation levels are the most common factor in hair loss. Permanent hair loss is more common at higher concentrations. The hair’s pigment or texture may undergo a change during the regrowth process, which typically takes place between three and six months following the conclusion of radiation therapy. Furthermore, the hair may regenerate in a manner that is irregular or diminishing.
