Have you ever looked into the mirror and felt concerned about why one of your breasts is bigger than the other? If yes, you’ve landed at the right place. Breast asymmetry is when one breast differs from the other in terms of size, volume, position or form. And it’s common. A woman’s breasts may fluctuate in size or volume for a variety of reasons including trauma, puberty and hormonal changes. Come let us find out more about unequal breast size.

Dr Tanaya Narendra, popular on social media as Dr Cuterus, gave her Instagram followers a sneak peek into the subject of breast size, which not many women up about.

The expert says that the phenomena is common. For most people, it’s the left breast which is bigger. But if your right breast is bigger, there’s nothing abnormal about it. This difference can be as large as one cup size and there’s nothing to be worried about.

Some likely causes of unequal breast size are:

1. Normal differences in growth

Most of our body parts are not perfectly symmetrical. This may include our legs, hair and eyebrows. So, the reason for your unequal breasts may be due to typical physiological variances which are beyond one’s control.

2. Period cycle

During each phase of your menstrual cycle, your breast tissue keeps changing. For instance, when you are ovulating, they could seem bigger and more sensitive. When menstruating, they contract.

3. Change in hormones

Even if both the breasts finish developing at the same time, it is quite possible that one breast may begin to develop before the other when hormones shift during puberty. So, it can be due to hormonal changes.

4. Traumatic injury

Breast asymmetry can result from injury to breast tissue before it has fully matured, possibly between the ages of 10 and 11 when adolescent girls go through the phase of puberty. Asymmetric breast growth may result from traumas to the chest such as some big injury, trauma, infection, or radiation.

5. A skeletal issue or some medical problem

One breast grows noticeably bigger than the other in a condition called juvenile or virginal hypertrophy of the breast, which is not that common. This medical problem frequently results in physical and psychological issues and is treated by a surgery.

According to Dr Narendra, a sudden change in the size of your breasts should raise an alarm, and you must visit a doctor in that case.

Is breast asymmetry a symptom of breast cancer?

Breasts that are uneven are typically nothing to worry about. Regular scans are necessary to ensure that any breast abnormalities are found early, though. However, if the density of your breasts suddenly changes or if the asymmetry of your breasts varies very frequently, this could be a sign of breast cancer.

According to a 2015 research, women who have a breast asymmetry ratio of over 20 percent may be more likely to get breast cancer.
