My left breast has been itching and has a minor rash. My whole body also itches, and its very cold in here. Could this be allergies or cancer?

Not cancer. Cancer usually does not itch you need to have someone examine the area if the problem persists. However you may simply have dry skin for which applying a moisturizer immediately after bathing may help. Then it may also be from a contact allergy especially if you had worn a new bra which had not been washed prior.

What do you suggest if my left breast. It also itches something fierce. Could it be a clogged milk duct or maybe an infection of some kind?

Breastfeeding? It sounds as if you are breastfeeding? If so a clogged duct can present as a tender red area of the breast. The itchiness also concerns me for a yeast infection, especially if the nipple is involved. Try a warm compress on any red area tonight, be sure the baby is draining the area by compressing the milk ducts in that area. See your physician if this is not better in 24 hours, may need yeast rx.

See a doctor. Based on your description, a fungal infection commonly known as "tinea" would be most likely, particularly if you have pendulous breasts, as the warm environment underneath the breast makes it more likely for a fungal infection to grow. However, if it has been there that long and is growing, there is strong consideration for immediate biopsy which would require in-person consultation. Read more...
