If an uncomfortable breast cyst recurs month after month, or if a breast cyst contains blood-tinged fluid and displays other worrisome signs, surgery may be considered. Epidemiology
It is estimated that 7% of women in the western world develop palpable breast cysts.In males, the occurrence of breast cysts is rare and may (but need not) be an indication of malignancy. Cysts and bra support
Some women experience breast pain, especially when engaging in vigorous physical activity. A properly fitted sports bra, which compresses or encapsulates breast tissue, is designed to reduce pain caused by exercise. References

Osteoporotic bone marrow defect is a condition which may be found in the body of the mandible. It is usually painless and found during routine radiographs. It appears as a poorly defined radiolucency (dark area) where there was a previous history of an extraction of a tooth. It may resemble a metastatic disease. It is a localized increase of hematopoietic bone marrow that creates a radiolucent radiographic defect. They occur more commonly in women in the midyears and show a predilection for the molar region of the mandible. They are especially common in extraction sites. Scattered trabeculae may extend short distances into the defect or, in some instances, through it, giving the defect a fairly characteristic appearance. Naturally there are no clinical symptoms. Cause
The cause remains unknown. Diagnosis
Differential diagnosis
This defect may easily be mistaken for a cyst or tumor. Biopsy is required to rule these out. Treatment
No treatment is required. References
