Pregnancy-associated boob cancer (PABC) is circumscribed as boob cancer that develops during or within digit year after pregnancy. It is relatively rare, with approximately 10% of all boob cancer cases under geezerhood 40 occurring in pregnant women. However, some researchers hit speculated that the frequency of PABC may process as the average geezerhood at the instance of maternity increases.

Some research has indicated that PABC has a worse outcome than other boob cancers; however, this could also be attributable to teen age, since most women with PABC tend to be teen and boob cancer in teen women tends to hit a worse prognosis.

Researchers from M. D. playwright person Center analyzed data from 652 women ages 35 and younger who were diagnosed with boob cancer between 1973 and 2006. The group included 104 women with PABC—51 who were diagnosed during their maternity and 53 who were diagnosed within the mass year.

The researchers observed that the tumors in the pregnant women were more advanced upon diagnosis; however, this could be because the maternity masked symptoms, leading to a suspended diagnosis. The data indicated that the rates of overall survival, distant metastases, and locoregional recurrence were similar among women with PABC and those with non-PABC.
