Violet, while it is true that itching can be one symptom of a relatively rare form of breast cancer called inflammatory breast cancer (IBC), usually the itching would be accompanied by swelling, redness, and other symptoms.  The itching I felt when I first started having IBC symptoms was deep in my breast, not itching on top of the skin.  All of my symptoms were on one side.  For more information about distinguishing between itching that might be cancer and other types, you might want to read this column.  This is the time of year when many people are plagued by dry itchy skin, and breasts, which have delicate skin and often enclosed in bras that can rub or irritate, are especially prone to this problem.  Check with the doctor is you do develop redness, scaly skin, and/or swelling.  The doctor may also be able to prescribe the best cream to help with the itching.
