Gynecomastia in Men
Between the ages of 10 and 25, swelling under the nipple may suggest a condition known as gynecomastia. Hormonal changes during adolescence can sometimes result in swelling of the
male breast. Gynecomastia may last a few months and there is usually nothing to be concerned
about. See your doctor if breast development increases or if you are at all concerned.
Gynecomastia may also occur as a result of some medications or if you are taking hormones --
discuss this with your doctor.
Runner's Nipple & Men
Red, sore, cracked or blistered nipples are often associated with irritation caused by loose
clothing rubbing against the skin. Apply some petroleum jelly or some antibiotic
ointment, or cover the affected area with an adhesive bandage. See your doctor if a growth
occurs or if you are concerned.
Breast Cancer & Men
Yes, men get breast cancer too. A hard, painless lump under the nipple could indicate
something serious. You should make an appointment to see your doctor as soon as possible.
