I have almost the same complaint as you. I have been experiencing a warm feeling inside my left breast. I dont feel like this on my right breast. I started feeling this 3 years ago, I had mammogram that time but nothing. My fault though, was I didnt undergo ultrasound which was advised bec. I have a dense breast. My doctor now suspects some hormonal changes bec. I was using oral contraceptives. She advised me to stop OC and wait after 2 months. If I still feel feel warm after that time then I'll undergo mammo. Now my problem is I dont know if I still can wait for that time. Im very worried now esp. after reading abt. IBC/ Inflammatory Breast cancer. Please if you now have answers to your/our queries pls. share the info. tnx
