Side Effects After Cancer Treatment

There are different types of side effects you may have during or after cancer treatment.

  • Short-term: side effects that happen while you are on treatment and end shortly after.
  • Long-term: side effects that happen while you are on treatment and last for months to years. Some of these side effects will not go away. Example: neuropathy.
  • Late effects: side effects that happen months to years after you have finished treatment. Example: scar tissue forming and causing health issues.

This article focuses on the late effects of radiation treatment for bladder cancer.

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

Late Effects After Radiation for Bladder Cancer

Side effects from radiation treatment affect the area of the body in the treatment field. The treatment field includes the cancer and in some cases nearby healthy tissue. How radiation is given has changed over the years, leading to a lower risk of late effects. Talk with your radiation oncologist to find out which areas were in your treatment field.

Late effects of radiation treatment for bladder cancer include:

Bladder Problems

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

  • Scar tissue: This can develop leading to a decrease in how much urine your bladder can hold.
  • Hemorrhagic Cystitis: This is inflammation inside of the bladder that can lead to bleeding. Signs of hemorrhagic cystitis include urinary frequency (needing to pee often) and urgency (needing to go quickly), blood in your urine, or pain when peeing. If you have any of these symptoms, tell your provider right away.
  • Urinary Tract Infections: 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), urinary frequency (needing to go often), or see blood in your urine, call your provider.
  • Bladder Cancer: Radiation to the bladder can increase your risk of developing bladder cancer. Signs include blood in the urine, urinary frequency (going often) and urgency (needing to go right away), urinating at night, and incontinence (loss of bladder control). Tell your provider if you have any of these symptoms.

These late effects all have similar signs. You may need 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 or smoke, because these irritate the bladder and increase your risk of bladder cancer.

Bowel Problems

The bowel is sensitive to the effects of radiation. If the rectum, colon, or small bowel are in the treatment area, late effects can include:

  • Scarring and strictures: Damage to the tissue of the bowel can lead to scar tissue. This scar tissue can lead to a stricture (narrowing of a part of the body) and 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 (belly) pain, constipation, vomiting, weight loss, or bloating. If you have severe abdominal pain with vomiting and constipation you should be seen by a provider right away.
  • 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 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 seeing a gastroenterologist (GI Doctor). You should also meet with a registered dietitian (RD) who can look at your diet and give you ideas 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, the 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. 
    • If you were treated before the age of 18, you should begin colon cancer screening with colonoscopy or DNA stool testing 5 years after treatment or at age 30, whichever is later.
    • 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.

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

Radiation to the pelvis for men may cause problems with sexual health such as infertility (not being able to father a child), low testosterone levels, low sperm count, or not being able to get and keep an erection (erectile dysfunction).

  • If you want to have a child, it may help to speak to a fertility specialist. They can look at 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 less seminal fluid. This can cause a man to have a “dry orgasm.” In these cases, the man is still able to reach orgasm but will have little or no fluid released.
  • You should speak openly with your provider about these issues. For those having erectile dysfunction, medications such as sildenafil (Viagra) may help. If these medicines are not helping, you should see a urologist. There are other ways that you can get an erection, such as using an implant or pump.

Impact on Reproductive Organs, Sexual Function, and Fertility (for Women)

Women may have long-term changes to their vagina and uterus after radiation to the pelvis. You may experience vaginal dryness, atrophy (shrinkage and thinning of the tissues), less feeling/sensation in the genital area, bleeding, or painful intercourse. 

Sexual Health
  • Water-based lubricants and moisturizers (Replens) can help to make sexual intercourse more comfortable. 
  • Regularly applying vitamin E to external vaginal tissues or using suppositories (medication you put into your body through an opening like your rectum or vagina) may help the tissues get stronger and reduce friction and discomfort. Some women may benefit from low-dose estrogen suppositories.
  • Scar tissue in the vagina may cause the size of the vagina to narrow or shorten. Regular use of vaginal dilators, which are placed in the vagina for short periods of time, is recommended for all women who have had radiation to the pelvic area. This will help stretch the vaginal tissues and make intercourse and vaginal exams more comfortable. 
  • Physical therapy to strengthen pelvic floor muscles has been shown to decrease pain with intercourse and improve sexual health. Women with pain in the vulvar region may find relief with topical lidocaine (a numbing agent you apply to the skin).
  • If sexual health changes are affecting your quality of life, discuss them with your providers. It may help to see a therapist who works with cancer survivors with sexual concerns.
Fertility and Childbearing

Radiation fields that include the ovaries can result in damage to a woman's supply of eggs (oocytes). The risk of infertility is higher with higher doses of radiation. Your period will likely stop during treatment but may return in women younger than 40. If it returns, you may still be at risk of going into menopause earlier than your peers. This can be important to know for family planning purposes.

  • If you would like to become pregnant, it can help to see a reproductive endocrinologist. They can review the cancer treatments that you got and talk about options with you.
  • After ovarian radiation to the ovaries, some women will go into early menopause (menopause that occurs before natural age). Early menopause can increase your risk for osteoporosis or heart disease. It may help to see an endocrinologist even if you do not wish to become pregnant. They can talk with you about ways to reduce these risks, like hormone supplements, calcium, vitamin D, and exercise, depending on your case.
  • Radiation to the uterus (womb) can cause the uterus to shrink, have less elasticity (ability to stretch) and develop scar tissue. These changes in the uterus can cause a higher risk of miscarriage, preterm labor, and babies born at low birth weight. If you wish to become pregnant, you should be seen by a high-risk pregnancy specialist.

Kidney Damage

When the radiation field includes the kidney(s), renal insufficiency (decreased kidney function) and hypertension (high blood pressure) can happen. The kidneys are not typically included in the bladder radiation field but may be in some cases. Ask your radiation oncologist about what organs were in your treatment field.

  • Your risk for kidney problems after radiation is higher if you have diabetes, only have one kidney, have a history of high blood pressure, or if you have taken other medications that can cause kidney damage.
  • Have your blood pressure checked at your annual check-ups. If needed, your blood pressure may be treated with medications.
  • Your team will also watch your kidney function through blood testing (basic metabolic panel) and urine tests (urinalysis).
  • Eating a balanced, healthy diet can support healthy blood sugar levels and help protect your kidneys from further damage.

Skin Changes

Radiation can lead to changes in the skin that don’t go away.

  • You may find 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 cause hair loss in the treated area. Your hair might never grow back.
  • 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 the area treated. 
  • You may get chronic or recurring ulcers of the skin in the area treated. Blood vessels of the skin may become dilated (larger) and more visible, but this is not harmful.
  • If the skin feels tight or sore, you can apply vitamin E.
  • 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 not to be 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, you should call your provider for an assessment.

Managing Late Effects

Tell your care team about any new or worsening symptoms. Some side effects need care from healthcare providers who specialize in working with cancer survivors. There are Interdisciplinary survivorship clinics at many cancer centers. If there is not a survivorship clinic near you, talk with your oncology care team about support for managing your late effects.

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