The Urologic Side Effects Of Breast Cancer Treament

Women undergoing treatment for breast cancer, specifically chemotherapy, know all too well about the side effects including nausea and hair loss. But most women are not aware of how breast cancer treatment affects their bladder health.

Physicians typically do not address the urologic side effects of breast cancer treatment and most women dont think to ask. The fact is, chemotherapy is a bladder irritant, explained Lisa Hawes, M.D., a female urology specialist at Chesapeake Urology in Maryland. Many women going through breast cancer treatment who experience the symptoms of a bladder infection or a urinary tract infection such as frequency, urgency, and burning, think the bladder issues are temporary and will go away once the treatment is over. But many women continue to experience bladder symptoms well after treatment.

How Chemotherapy Affects The Bladder

Bladder issues and UTIs are sometimes caused by changes in estrogen levels. Breast cancer chemotherapies may be anti-estrogens, meaning they work against hormone-receptor-positive breast cancer and may stop some cancer cells from growing. Used to prevent and treat breast cancer, anti-estrogens can also cause vaginal atrophy, which can lead to bladder issues such as recurrent UTIs. Dr. Hawes explains that the bladder tends to be estrogen sensitive, so as women lose estrogen, many experience common UTI symptoms of urinary frequency and urgency.

Some Background On Breast Cancer

Before going into more detail, its important to understand a little background on breast cancer. First of all, every breast is unique. What might be normal for one person isnt necessarily normal for another. The important thing to monitor in breasts is any changes over time, but even this isnt a definitive cause to be concerned. Breasts change and these changes can be results of your period, pregnancy, breastfeeding, gaining or losing weight, and even certain medications.2 As you age, your breasts are going to continue to change. Additionally, there are a number of conditions that can cause a lump to appear in your breasts aside from breast cancer.2 For example, two of the most common causes of breast lumps are fibrocystic breast conditions and cysts.2

To better understand your body and catch signs of lumps early, performing self-checks are recommended. Just remember, if you find a lump, dont start panicking. Schedule an appointment with your doctor to investigate further and come to a diagnosis. Often, the lumps are non-cancerous and go away on their own.

While checking for lumps is one of the most common ways of early detection, there are still other symptoms that you should watch out for. Some of the early warning signs of breast cancer include:3

If you notice one or more of these symptoms, its a good idea to call your doctor and get more detail. A lot of other conditions or fluctuations in hormones can contribute to the symptoms above so

    I am 15 years past treatment for a different sort of cancer and it still huts where they radiated me.

    I have no way to speak about tamoxifen but, in reading here on whatnext, it seems worse for some than for others.

    Best wishes for you to feel better soon

    If your estrogen is suppressed, which is what tamoxifen does, it can cause urinary problems and infections. If you have those symptoms, you need to call your doctor and have your urine checked. You may also have vaginal dryness or pain.

    If so, oncologists have approved breast cancer patients using a smaller than usual dose of Premarin cream vaginally only, which means it’s absorbed vaginally rather than going all over your body. Mine prescribed a pea-sized amount 2-3 times a week, and it helps a lot. Best wishes.

  • BarbarainBham

    P.S. You should always call your oncologist when you have problems. Sometimes they want to check you to be sure you are healing well. I had quick, sharp pains after radiation, and my oncologist said that’s how it feels when nerves are regenerating and healing. Any pain other than that could be an infection, etc., so stay in close touch with your doctor’s office.

    Testing A Topical Drug For Breast Cancer Prevention

    Four years ago, Seema Khan, M.D., of Northwestern University Feinberg School of Medicine led a small study that compared the proliferation of abnormal cells in the lining of the breast ducta condition known as ductal carcinoma in situ among women treated with the gel applied to the breast skin and women treated with oral tamoxifen.

    We found a similar reduction in the growth of DCIS cells from both the gel and the pill form of the drug, and the concentrations in the breasts of women who were treated with the gel were quite good, said Dr. Khan, who is leading one of the new clinical trials of the tamoxifen gel. 4-OHT has the feel and consistency of hand sanitizer gel, she noted.

    Women in the gel group also had lower blood levels of certain biomarkers associated with side effects than women in the oral tamoxifen group, the researchers found.

    Dr. Khan cautioned that those results need to be confirmed by the randomized placebo-controlled clinical trials now under way. She also noted that the 4-OHT gel is intended for use in a specific group of women.

    This approach is for healthy women who have an increased risk of breast cancer and for women with DCIS, said Dr. Khan. When the problem is confined to the breast, this approach would be appropriate.

    Using a topical drug would not be a viable approach once breast cancer cells have broken through the duct walls, because those cancer cells can go elsewhere in the body, she explained.

    Urogenital Problems And Breast Cancer Treatment

    Urogenital problems refer to issues within the urinary and genital areas, including the vulva, vagina, and lower urinary tract. Up to 5075% of people with breast cancer experience one or more symptoms related to the genital and urinary areas1,2. These side effects are part of an array of menopausal symptoms brought on by certain breast cancer treatments, especially hormone treatments such as tamoxifen and aromatase inhibitors. This is because these treatments systematically reduce the amount of oestrogen available. This reduction in oestrogen is the main cause for urogenital side effects.

    Oestrogen is a hormone that carries out important functions throughout the entire body but the effects of its reduction are more severe in urogenital areas such as the vaginal, urethra, bladder and pelvic floor muscle tissue, as they contain high concentrations of oestrogen receptors3.

    In this blog we will look at the effects that breast cancer therapies can have on the urogenital area and discuss some useful tips to help you manage these side effects.

    Re: Bleeding After Stopping Tamoxifen Help

    Hello there, I am experiencing the same thing. After stopping Tamoxifen last year after 5yrs I was advised that if I wanted I could continue on Tamoxifen or switch to Anastrazole. I had a blood test done in June 2017, 6 weeks after stopping Tamoxifen organised by my breast care Nurse and it said my FSH levels were high and that I was in menopause. I had a uterus scan and a gynaecologist check, also a pipelle biopsy which came back as normal.

    Eventually I started on Anastrazole in Jan this year. Then on March 15th I had some light vaginal bleeding that turned out to be a period by next day. My last period was in November of 2014. I had to stop the Anastrazole. My GP has ordered another hormonal profile and I had the blood test today. This period has been heavy and not stopped as yet. First 4 days heavy, then it slowed down. Thought it stopped yesterday but a little discharge today. Hopefully it will stop. I will be 54 next month.

    Can anyone tell me whether their period lasted for more than a week?
