Breast pain is common and rarely a symptom of breast cancer as commonly believed. However, if you experience redness or swelling, it could be a sign of infection (particularly in breastfeeding women) and you should see a doctor ASAP.

Here are some common reasons you might be experiencing sore boobs.

You have your period
One of the most common reasons for breast soreness is from fluctuations in your hormones the week before your period.

You have a rash

You could be pregnant
Yet another thing your hormones could be behind! The fluctuation between estrogen and progesterone that are preparing your breast for milk production could cause tenderness. This can even happen as early as two weeks after conception.
