Itchy Nipples? A Lactation Expert Shares 9 Potential Causes

An impromptu google search for "itchy nipples" or "why does my nipple itch" can quickly send you down an anxiety-inducing medical rabbit hole. Results pointing to "breast cancer" and "early pregnancy" may set off alarm bells in your head, but the reality is that — generally speaking — itchy nipples are nothing to be afraid of. While they aren't always talked about, itchy nipples can be triggered by everything from your new laundry detergent to your old sports bra. If you want to stop your nipples from itching altogether, it's best to identify the root cause.

To get a better sense of what causes itchy nipples, we asked a lactation expert to outline some potential reasons. Beyond common causes of itchy nipples, she also answered some pressing questions about itchy nipples while breastfeeding, itchy nipples as an early indication of pregnancy, and itchy nipples as a sign of cancer. Read on to find out what may be causing your itchy nipples, and see what symptoms may warrant additional medical care.

Why Are My Nipples Itchy?

Although uncomfortable, some of the most common causes for itchy nipples are relatively benign. Irritation can develop due to your clothes, menstrual cycle, or even the weather. Here are a few other itchy nipple causes, according to lactation consultant Nicole Peluso, IBCLC.

Can Breastfeeding Cause Itchy Nipples?

Generally speaking, you shouldn't expect to have itchy nipples while breastfeeding, Peluso says. Itchy nipples while breastfeeding may be due to another underlying cause, which you can discuss with your healthcare provider. "Itching could indicate improper latch and positioning, irritants, allergens, or eczema," Peluso says. "If itchy nipples are accompanied by pain, it can also be a sign of a more serious issue such as thrush — an infection that is best identified by a lactation consultant and treated by a doctor."

Are Itchy Nipples a Sign of Pregnancy?

The short answer is that itchy nipples can occur early on in pregnancy, but it's not a sure-fire sign that you're pregnant. Peluso attributes this irritation to the expansion of the breast tissue caused by pregnancy hormones. "This can lead to tight and itchy skin," she says. Still, Peluso wouldn't recommend using itchy nipples as a "definitive sign" of pregnancy. To prevent itchy nipples during pregnancy, she suggests keeping your nipples and breasts well-moisturized.

Are Itchy Nipples a Sign of Cancer?

Rest assured that itchy nipples and breasts are not common signs of cancer. That said, there are a few rare conditions to look out for. "Paget's disease of the breast (develops in the nipple or the areola) appears as a red, scaly rash and might indicate breast cancer behind the nipple," Peluso says. Paget's disease of the breast may darken the area around the nipple (areola) and affects 1 to 4 percent of women, per the National Health Service (NHS). A biopsy or mammogram may be used to test for Paget's disease of the breast.

Aside from Paget's disease, there's another kind of breast cancer that may also cause irritation around the nipples, including itching. "Inflammatory breast cancer is a rare type of breast cancer that can cause skin changes in the breast," Peluso says. "With this type of cancer, the breast or part of the breast can become red, inflamed, painful and swollen. It can also cause itching of the breast." If you notice any significant changes in or around your nipple, it's a good idea to contact a medical professional.

Itchy Nipple Treatments

"The best way to reduce the itching is to identify the root cause so you can get the appropriate treatment," Peluso says. "If mild, use gentle soaps and moisturizers without added colors or smells, wash your bras often (especially sports bras that have a tendency to get sweaty)." This can reduce your chances of harsh chemicals or fragrances triggering contact dermatitis. For immediate relief, Peluso also suggests applying a cool compress. "Wet a cloth with cool water, squeeze out the excess liquid and place the cloth over your nipples to soothe the area," she says. You can also try wearing loose-fitting clothes to reduce chafing, stay moisturized with non-scented lotions, or sleep with a humidifier in the winter to prevent dry, irritated skin.

When to See a Doctor

"The great news is that itchy nipples are rarely a sign of a more serious condition," Peluso says. "In general, having itchy nipples is something you can manage on your own at home." That said, if the itch is severe and accompanied by pain, fever, chills, swelling, and/or discharge, she recommends contacting a healthcare provider. You may also want to see a doctor if your baby's mouth develops white patches (not from milk), or if itching comes within a few weeks of antibiotic treatment, both of which can be signs of thrush.
