Patient: Description of condition (onset, main symptoms, hospital visited, etc.): I am 19 years old. I had an ultrasound two years ago and the doctor said I had lobular hyperplasia, which got better after taking it for a while. Now my breast still hurts some time before my period. This year, I had another ultrasound and the doctor said it was better. Is it normal to have breast pain before menstruation? Is it possible to have lobular hyperplasia at a young age and have a higher chance of getting breast cancer in the future? Can you give me any advice? Thank you! Doctor: There are many misunderstandings and misinterpretations about lobular hyperplasia in the breast. It is not a single disease clinically or pathologically, but a combination of multiple changes with multiple names, such as cystic hyperplasia, lobular hyperplasia, fibrocystic mastopathy and so on. Clinically, they often present alone or simultaneously as breast pain or benign nodules that may fluctuate with the menstrual cycle; pathologically, they are multiple manifestations of poor breast structure. There are clinical and autopsy findings that almost all women with these clinical or pathological manifestations account for all adult women, and even among women without any breast symptoms, up to 90% still have corresponding pathological manifestations. It is therefore believed that none of the clinically or pathologically diagnosed mastocytosis may represent a pathological condition, and that a significant proportion or even the vast majority of them may be physiological in nature. Therefore, mastocytosis itself does not increase the risk of breast cancer. So, the solution to your problem is: let go of your worries and live happily!!! Just have a mammogram once in 1-2 years regularly. Hope it helps you!
