What is a late effect?

A late effect is a side effect that is caused by treatment but happens months to years after the cancer treatment has finished. Some side effects that you develop during treatment can last for months to years after treatment is completed (for example, fatigue or neuropathy). These are often called long-term side effects.

Late effects can be health issues or psychological, emotional, and practical challenges.

Late Effects After Radiation for Prostate Cancer

Side effects from radiation treatment are directly related to the area of the body being treated. Any area in the treatment field has a risk of being damaged, causing side effects. As radiation techniques have improved over the years, the risk of late effects has decreased.

Bladder Problems

Radiation to the bladder area can cause late effects to the bladder including:

  • Developing scar tissue, which can lead to a decrease in how much urine your bladder can hold. 
  • If given with chemotherapy medicines known to cause bladder damage (cyclophosphamide, ifosfamide), late effects can include hemorrhagic cystitis that causes bleeding from the bladder lining. Signs of hemorrhagic cystitis include urinary frequency (needing to go often) and urgency (needing to go right away), blood in the urine, and pain. You should report these to your provider right away.
  • Radiation to the bladder may also make you more prone to urinary tract infections. This type of infection can be treated with antibiotics. If you have burning when urinating (peeing), frequency (needing to go often), or see blood in your urine, call your provider.
  • Radiation to the bladder can increase the risk of developing bladder cancer. Signs of this include blood in the urine, urinary frequency, and urgency, urinating at night, and incontinence. Contact your care provider if you have any of these. 
  • These late effects all have similar signs. You may have urine tests or cystoscopy (inserting a small tube with a camera into the bladder) to figure out what is causing your issues. It is best to not drink alcohol and or to smoke, as these irritate the bladder and increase the risk of bladder cancer.

Bowel Problems

The bowel is sensitive to the effects of radiation. The late effects that may occur after radiation treatment that includes the rectum, colon, or small bowel include:

  • Scarring and strictures: Damage to the tissue of the bowel can lead to scar tissue. This scar tissue can cause a bowel obstruction. A bowel obstruction is when the normal movement of stool through the bowel is blocked. Call your provider if you are having any abdominal pain, constipation, vomiting, weight loss, or bloating. If you have severe abdominal pain along with vomiting and constipation you should be seen by a provider right away, either in the office or the emergency department. 
  • Ulceration and bleeding: Ulceration and bleeding can be caused by damage to the bowel tissues. Report any dark or black colored stools, bright red blood in your stools, in the toilet water, or on the toilet paper to your provider right away. You may need testing with a colonoscopy to find the area that is bleeding.
  • Chronic diarrhea: Report diarrhea that is causing weight loss to your care team. Medications to lessen diarrhea may be helpful. You may benefit from meeting with a gastroenterologist (GI Doctor). You should also meet with a registered dietitian (RD) who can help evaluate your diet and give you suggestions to lessen diarrhea and maintain or gain weight.
  • Fistula formation: A fistula is a connection (hole) between two parts of the body that are not normally connected. A fistula can form between the bowel and bladder, bowel and female reproductive system (uterus/ vagina), or the bowel and the skin. If you have urine, feces, or blood coming out of any opening that it should not be, you should call your provider right away.
  • Colon cancer: Radiation to the bowel can lead to colon cancer years after treatment is complete. If you were treated before the age of 18, it is recommended to begin colon cancer screening with colonoscopy or DNA stool testing 5 years after treatment or at age 30, whichever occurs later. Screening for the general population begins between the ages of 45-50. You should consider these 2 guidelines when deciding when to start colon cancer screening. You may need earlier screening if you have irritable bowel disease, chronic diarrhea or bleeding, ulcerative colitis, colon cancer in your family, or previous gastrointestinal cancers or polyps.

Lymphedema Risk

Surgery to remove lymph nodes or radiation to lymph nodes can cause damage to lymph nodes and lead to lymphedema. Lymphedema is swelling that can happen in the genital area, belly, buttocks, legs or feet after treatment. It can cause pain, be disfiguring, make activity difficult, and increase the risk of infection in the area.

  • Talk to your provider if you are having any new swelling. A Certified Lymphedema Therapist should be consulted at the first sign of swelling to try to keep the lymphedema from worsening.
  • You are at risk of infection in any area with lymphedema or that is at risk for lymphedema. If you experience any signs of infection, contact your care team right away or go to the emergency room. These signs include a sudden increase in swelling, an increase in pain, redness, the area is warm to the touch, or fever.

Impact on Reproductive Organs, Sexual Function, and Fertility (Men)

Radiation to the pelvis in a man may cause problems with sexual health such as infertility, low testosterone levels, low sperm count, or the inability to get and maintain an erection (erectile dysfunction).

  • If you want to have a child, you may benefit from speaking to a fertility specialist. They can evaluate the health of your sperm and your ability to father a child. 
  • In some cases, the prostate gland is affected by radiation, which can lead to a decrease in seminal fluid. This can cause a man to have a “dry orgasm.” In these cases, the man is still able to achieve orgasm but will have little or no fluid released.
  • You should try to speak openly with your provider about these issues. For those having erectile dysfunction, medications such as sildenafil (Viagra) may be useful. If these medicines are not helping, you should see a urologist. There are other ways that you can achieve an erection, such as using an implant or pump.

Nerve Damage

Radiation to the groin area can cause damage to nerves in the area. This damage is often caused by scar tissue pressing on the nerves or interrupting the blood supply to the muscles served by these nerves.

  • Radiation injury to the nerves and muscles is sometimes called radiation fibrosis syndrome. It tends to develop in the years following treatment and slowly worsens over time.
  • Symptoms can include pain, loss of strength (weakness), decreased feeling (sensation), loss of coordination, or loss of movement or function of the muscle. The area affected will depend on the area that was in the radiation field.
  • In rare cases, the autonomic nervous system (ANS) can be affected. The ANS controls things you don’t think about, such as blood pressure and bowel and bladder control. Signs of ANS dysfunction can be lightheadedness, fainting, extreme constipation, urinary incontinence, and erectile dysfunction.
  • If you develop any of these issues, report them to your provider. Some of these concerns can be caused by other health issues, so your provider will need to figure out the cause.
  • If radiation fibrosis is the cause, you may benefit from seeing a cancer rehabilitation physician or physiatrist, and physical or occupational therapists. These specialists can help manage symptoms through therapy, medications, and assistive devices.

Skin Changes

Radiation can lead to permanent changes in the skin.

  • You may develop new scars or notice changes in the color or texture of your skin. Radiation can also change the color and texture of your hair or can cause permanent hair loss in the treated area.
  • The soft tissue and muscles under the skin can develop scarring and/or shrinkage, which can lead to a loss of flexibility and movement or chronic swelling in this area.
  • You may develop chronic or recurring ulcers of the skin in the area treated. Blood vessels of the skin may become dilated and more visible, although this is not harmful.
  • If the skin feels tight or sore, you can apply vitamin E to the skin.
  • Use fragrance and dye-free soaps and moisturizers in the area if your skin is sensitive after radiation.

After radiation, the skin in the treated area is more sensitive to sunlight. This sensitivity will last for your lifetime. Practice sun safety, use plenty of sunscreen, wear a wide-brimmed hat, and keep skin in the treated area covered with clothing. Try to avoid being out in the sun between the hours of 10 am-4 pm when it is the strongest.

If you notice any new or worsening skin issues anywhere on your body, you should contact your provider for an assessment.

Managing Late Effects

If you experience any concerning or lasting symptoms, contact your care team. Some side effects require specialized care from healthcare providers experienced in working with cancer survivors. Interdisciplinary survivorships clinics are available at many cancer treatment sites.  If a clinic is not available near you, talk with your oncology care team about resources for managing your late effects.

After treatment, talk with your oncology team about receiving a survivorship care plan, which can help you manage the transition to survivorship and learn about life after cancer. You can create your own survivorship care plan using the OncoLife Survivorship Care Plan.
