Cancer treatment side effect: skin changes
Did you know that cancer treatments can cause changes to your skin?
Sometimes these changes are simply cosmetic, but other times they
may require attention from your care team.
To better understand skin changes that happen during cancer treatment
and how best to address these side effects, we spoke with Anisha Patel, M.D.
Here’s what she had to say.
What types of cancer treatments cause skin changes?
All cancer treatments have side effects, but patients are sometimes
surprised by the skin changes they see when receiving chemotherapy
and immunotherapy. Since these therapies are used to treat a variety of cancers— and we’re constantly expanding and improving their use through clinical trials — skin changes are common.
What are common skin changes during cancer treatment?
The most common things we see are rashes and dry skin, which may be
accompanied by itchiness or burning of the skin.
Chemotherapy and immunotherapy can also change the color, or pigment,
of the skin, but it’s less common. You may not even notice. Depending on the
therapy, you may see lightening or darkening of skin, hair and nails.
A less common side effect that we see with newer treatments is the development
of new growths, such as moles, warts and raised areas of the skin.
It’s important to know that the type of skin side effect you may experience
depends on your medical history and the type of treatment you’re receiving,
so talk with your doctor about what you should expect.
Why do these skin changes happen?
Chemotherapy and immunotherapy fight cancer by targeting specific
molecules in tumors. Those same molecules are also in our skin,
hair and nails, so patients can experience side effects in those areas
during cancer treatment.
Are these skin changes permanent?
Typically, changes to your skin related to chemotherapy and immunotherapy
aren’t permanent. When you stop treatment, we’ll see your skin return to
its previous state.
Also, these changes aren’t necessarily negative. Research has shown that
certain rashes correlate with having a better tumor response to the treatment.
So in some cases, when a patient gets a rash, despite it being uncomfortable
and possibly itchy, it can be an indicator of a good overall treatment outcome.
What can I do to cope with skin changes during cancer treatment?
Unfortunately, you can’t avoid treatment-related skin changes entirely, but there
are steps you can take to help reduce the discomfort. Before beginning
cancer therapy, we suggest you start moisturizing your skin regularly. Also, if you
have a history of eczema, psoriasis or skin cancer, see a dermatologist to
address those concerns before beginning treatment so that they aren’t amplified
during chemotherapy or immunotherapy.
Also, some types of chemotherapy and immunotherapy can make you more
sensitive to the sun, so we commonly see sunburns. In order to prevent that,
practice sun safety by limiting your time in the sun and wearing sunscreen with
SPF 30 or higher, as well as sun-protective clothing, whenever your skin is
exposed.
Lastly, try wearing comfortable shoes. We’ve seen a few therapies where
patients experience an associated rash in areas that are under pressure such as
the balls of the feet or with bunions. If your shoes are too tight and rub your feet,
you’re at a higher risk of experiencing this rash.
Are any of these changes dangerous?
New growths related to cancer treatment can be concerning. Most are benign
(non-cancerous), but others are malignant forms of skin cancer. It’s possible to
develop skin cancer that’s caused by your cancer treatment, even if you’ve
already received treatment for another type of skin cancer.
We advise our patients to conduct a monthly skin self-exam to catch these
growths quickly. Let your oncologist know if something seems suspicious so
that you can get a referral to a specialized dermatologist. If you’ve had a history
of skin cancer or are at increased risk, make sure you see a dermatologist
regularly during your cancer treatment. If you’re a patient at MD Anderson, you
can ask your doctor to refer you to one of our dermatologists.
Is there anything else you’d like patients to know?
Don’t be alarmed if you experience skin changes during treatment. Helping
patients cope with these changes is a big part of what MD Anderson’s
dermatology team does. We may not always be able to make the change go
away immediately, but we can help provide relief. Our goal is to make sure
you’re as comfortable as possible so that you can continue on the best course
of treatment for the cancer you’re facing.
