A woman’s breasts are naturally designed to provide nourishment for the infant and child. Many parts responsible for creating the breasts include the fatty areas, lymph vessels, muscle, connective tissue, milk ducts, and breast tissue.
A woman can get agitated when she discovers one of her breasts is bigger than the other. This does not usually mean she won’t be able to breastfeed her child properly, neither does it mean she has a higher risk of developing breast cancer. Most women realize at some point that they have one breast bigger. This is usually very normal.
Apart from breast size, some women also discover they have different sized feet or ring size from one finger to the other.
And if you find one breast smaller than the other in newborn babies, this is usually caused by the hormones in the mother before birth, and will resolve as soon as the body of the baby grows and develops. This usually happens within a few days.
It’s important to note that your body isn’t guaranteed to grow at the same rate on both sides, so having one breast bigger than the other is very common especially during puberty. However, the breasts do settle down into a similar size once you hit adulthood.
However, if the breasts continue to be different sizes, there might be a few reasons:
- Hormonal changes
A woman’s hormones affects everything, including breast size. This happens during puberty, menstrual cycle, pregnancy, breastfeeding, and menopause. It is also very common in women who are taking hormone replacement therapy or certain hormonal birth control methods. It is mostly not a cause for alarm.
Cysts are tiny fluid-filled sacs that can be found anywhere in the body. They are also found in breasts right before a woman’s menstrual flow. They often disappear between periods.
- Breast cancer
Breast cancer may cause the affected breast to increase in size, though this is rare. It is advisable to have your breasts checked by a specialist if you notice one is bigger, especially with associated pains.
This is also called “breast mouse”. It is a smooth swelling that can be moved around underneath the breast tissue. It is not usually cancerous. The presence of fibroadenoma in one breast may cause increase in size.
Lipoma is an area of fatty tissue in the breasts that can cause it to appear larger than the other.
When breasts implants goes wrong, it can feel as if there is a hard lump underneath the breast tissue.
- Injury or trauma
Injury to the breast can cause blood to gather underneath the affected breast. This might be an area of fatty tissue that develops a hard lump and swells or increases in size.
Note: Having one breast bigger than the other might not necessarily be a sign of an underlying condition. It could simply be the way your body is. However, you should consult your doctor in areas where you need check-up or clarification.
