There is a type of cancer called inflammatory breast cancer that does not have the usual symptoms of breast cancer- lumps, etc. You can youtube news reports about it. 'IBC' Inflammatory Breast Cancer. Or you can google it. Persistant itching is a symptom... Even if you feel back to normal now I would still encourage you to educate yourself, and your friends about it. If you're still considering going to the doctor it would be worth mentioning to him, as the news reports on youtube say a lot of doctors seem to overlook it, simply perscribing antibiotics, diagnosing it as a possible bug bite or something...
