Could Itching Be a Sign of Breast Cancer?

Although itching of the breast and nipple is common in women, it is generally not possible to say that breast itching indicates inflammatory breast cancer. This breast cancer type is uncommon, but its risks may still cause concern. Symptoms of inflammatory breast cancer can differ from those of most breast cancer types.

When Can Breast Itching Be a Sign of Cancer?

Unusual itching felt in the breast should be medically evaluated.

If breast itching is accompanied by the following signs, it is useful to see a doctor as soon as possible:

• Redness in either breast
• A change in breast texture, such as an orange-peel appearance
• Breast swelling and sudden enlargement unrelated to puberty or weight gain
• Increased breast temperature
• Hardening of the breast

These signs and symptoms may indicate a risk of inflammatory breast cancer. The figure below illustrates a typical appearance of inflammatory breast cancer .

In addition, itching confined to the breast or extending toward the areola (the area around the nipple) may indicate Paget disease of the breast , a rare type of breast cancer referred to by this name. This cancer usually involves red, thickened tissue and sometimes a crusted lesion. It may cause pain or itching, and the nipple may become deformed or retract.

Inflammatory breast cancer accounts for %3 of all breast cancers, and Paget disease for %1

Harmless Causes of Breast Itching

• Breast infections (mastitis): Often occurring in breastfeeding women, signs of breast infection may include pain, redness and itching. Antibiotics may be needed to treat mastitis. If it does not improve after treatment, possible breast cancer is investigated.
• Dermatological: Another cause of breast itching may be a skin reaction to something encountered recently, such as clothing, detergents, perfumes, lotions or soap. Keeping the skin moisturized with fragrance-free products as much as possible is recommended. Make sure clothing contains no detergent residue.
• Fungal infection: A fungal infection anywhere on the skin causes itching. It may develop because of tight clothing, persistent moisture or nonbreathable underwear. You may need to see a doctor and use antifungal medicine. Keep your skin as dry as possible and choose loose cotton underwear.
• Postoperative reaction: Itching may occur during healing after breast surgery. It is particularly common with breast implants (silicone) because the skin stretches. However, itching in these situations is not permanent. Consult your doctor if it does not resolve within a few months.
• Other benign conditions: Weight gain, puberty and pregnancy generally enlarge the breasts and may cause itching as the skin stretches. Rarely, nickel in bra underwires may cause an allergic reaction in some women. A nonwired bra can be used.

Breast itching is usually not a sign of breast cancer. However, seeing your doctor for an appropriate assessment is important. Having mammograms at intervals suitable for your age is also important.
