Radiation therapy, also known as radiotherapy, is a primary treatment for cancer. Being well-prepared and understanding the treatment can help alleviate some of the associated stress. If you have any questions regarding your cancer treatment, please contact your oncologist, doctor, or nurse.
Radiation therapy utilises X-rays to destroy or injure cancer cells, preventing them from multiplying. It can be used to treat both primary and advanced cancers. Additionally, radiation therapy can reduce the size of the cancer and alleviate pain, discomfort, and other related symptoms.
Radiation therapy can serve as the main treatment or support other treatments. Adjuvant radiation therapy may be used to shrink cancer before surgery or to eliminate remaining cancer cells post-surgery. It is sometimes combined with chemotherapy for enhanced effectiveness
The use of radiation therapy may be the primary treatment or may be used to assist another treatment. It is possible to perform adjuvant radiation therapy to shrink cancer before or after surgery to stop the growth of any remaining cancer cells. Occasionally, it is used in conjunction with chemotherapy.
Radiation therapy can serve several purposes:
You will receive treatment based on the type of cancer, where it is located, its size, your general health, and any previous cancer treatments you have received. Some patients require only one treatment, while others require radiation therapy five days a week for several weeks. During internal radiation therapy, implants may be left in place for a few minutes, one to six days, or permanently.
While you may feel discomfort from the implant during internal radiation therapy, you should not experience any severe pain or symptoms of illness. You may experience radiation outside your body while your radioactive implant is in place. When your implant is in place, there will be a limit on the number of visitors.
Depending on the area of your body being treated, you may experience side effects. The following are possible side effects:
Most side effects can be managed and gradually disappear once your treatment is complete. In some cases, side effects may be permanent, or they may not appear until after treatment has been completed. The radiation oncologist may change the treatment or prescribe a break if the side effects are severe. If the doctor believes that pausing treatment could negatively affect how well it works, a break may not be possible.
Once treatment has been completed, you will have regular check-ups with your doctor. You may undergo scans or tests during your physical examination to determine whether the cancer has responded to treatment. Before you can determine the full benefits of radiation therapy, it may take some time after your treatment.
Since cancer cells continue to die for weeks or months after treatment ends, your medical team will not be able to provide you with progress updates throughout treatment. However, they may be able to assist you in managing any side effects you may experience.
In the case of palliative radiation therapy, the relief of symptoms indicates that the treatment has been successful. It may take a few days or weeks for this to be completed.
You will not be able to receive radiation therapy if you are expecting, as radiation can harm a developing child. During treatment, it is critical that you do not become pregnant. Radiation therapy can damage sperm, you and your partner should use contraception while receiving radiation therapy and for approximately six months afterwards. You can obtain more information about radiation therapy and pregnancy from your physician.
The radiation oncologist may change the treatment or prescribe a break if the side effects are severe. If the doctor believes that pausing treatment could negatively affect how well it works, a break may not be possible.
Since radiation does not remain in your body during or after external radiation therapy, you will not become radioactive. Taking precautions with bodily fluids is not necessary, and it is safe to be around family, friends, children, and pregnant women.

Understanding radiation therapy and being prepared for the treatment can help lessen the associated stress. Always consult your oncologist, doctor, or nurse if you have any questions regarding your treatment.
