Radiation therapy is a common treatment option for prostate cancer. Radiation therapy aims to kill the cancer cells in the prostate while minimizing damage to surrounding tissues. While radiation therapy can be effective, it can also cause side effects. Here is a week-by-week guide to help you understand the side effects that may occur during radiation therapy for prostate cancer:

​

Week 1:

During the first week of radiation therapy, you may not experience any side effects. However, some people may develop mild skin irritation or redness in the treatment area. This can be treated with moisturizers or creams recommended by your healthcare provider.

​

Week 2:

As you enter into the second week of radiation therapy, you may start to feel more tired than usual. This is normal and is caused by the radiation treatment. You may also experience urinary frequency, urgency, or discomfort. These side effects can be managed with medication and dietary changes. It is important to stay hydrated and avoid caffeine, alcohol, and spicy foods.

​

Week 3:

During the third week of radiation therapy, you may notice that the urinary symptoms become more pronounced. You may also experience bowel changes, such as diarrhea. These side effects can be managed with medication and dietary changes. It is important to eat a low-fiber diet and stay hydrated.

​

Week 4:

In the fourth week of radiation therapy, you may experience fatigue, urinary symptoms, and bowel changes again. You may also notice that your skin in the treatment area is still sensitive and may continue to peel. It is important to continue following the skincare routine recommended by your healthcare provider to prevent infection and promote healing.

​

Week 5:

During the fifth week of radiation therapy, you may experience fatigue, urinary symptoms, bowel changes, and skin irritation again. You may also notice that your sense of taste has changed or that you have a metallic taste in your mouth. This can be managed by eating small, frequent meals and avoiding spicy or greasy foods.

​

Week 6-9:

In the final week of radiation therapy, you may experience fatigue, urinary symptoms, bowel changes, and skin irritation again. You may also experience sexual dysfunction, including erectile dysfunction or decreased libido. It is important to discuss any sexual dysfunction with your healthcare provider, as there may be treatment options available.

​

After Treatment:

After you have completed radiation therapy for prostate cancer, you may continue to experience side effects for several weeks. You may experience fatigue, urinary symptoms, bowel changes, skin irritation, and sexual dysfunction. It is important to continue to follow the skincare and dietary routines recommended by your healthcare provider. You should also schedule regular follow-up appointments with your healthcare provider to monitor any potential long-term side effects.
