Does Boob Size Matters?

Does boob size really matter? It's a debate I have had with my girlfriends for years. The grass is often greener on the other side, and so women continually exchange reasons why it is enviable to have either larger or smaller boobs. But are there any significant medical differences between having large or small boobs?

First, it's important to understand a little anatomy of the boob. Boob size is dictated more by the amount of fatty and fibrous tissue than the amount of milk-producing glands. This is important when thinking about size and its relationship to boob milk production and risk of boob cancer.

Generally speaking, size does not make a difference for important biological functions and conditions. Below are facts about some common medical misconceptions about boob size.

Boob size does not influence how much boob milk you can or will produce. Because boob size depends more on the amount of supporting fibrous and fatty tissue than the amount of milk glands, women with larger boobs do not necessarily produce more boob milk. Boob milk production is stimulated hormonally and increases with demand. Increasing the frequency of breastfeeding sessions with a baby increases the milk supply. Supply meets demand in most cases. While many factors can affect boob milk production — fatigue, stress and depression — do not add worry about your boob size to the stresses of motherhood.

If you are thinking about breastfeeding, don't discount your ability to breastfeed or give up without talking to a lactation consultant or your pediatrician. There are many ways to try to increase your milk supply, and difficulties occur for many women regardless of size.

Boob size does not influence boob cancer rates or prognosis. Researchers have found that boob size does not affect your risk of boob cancer. In addition, boob size does not affect your treatment outlook. The most common type of boob cancer comes from the cells lining the ducts of the milk-producing glands. Since women with larger boobs do not necessarily have more gland tissue, it makes sense that women with larger boobs do not have a higher risk of cancer. If you are worried about your ability to detect and treat boob cancer if you have larger boobs, remember that the studies do not validate your concerns. You are only more likely to miss cancer if you don't go looking for it with routine screening tests or if you ignore your intuition about a new lump or asymmetry.

The only caveat here is that obesity has been found to increase the risk of boob cancer. Overweight women can have larger boobs, but based on studies mentioned above, it appears that obesity is the factor more than boob size. Greater amounts of fat tissue increase the estrogen level, which is probably the cause of increased cancer risk associated with obesity.

Boob size does not affect the amount of pain you will have during a mammogram. In one study surveying women about their pain, larger boob size did not make a mammogram more painful. Don't let your fears about pain prevent you from getting appropriate boob cancer screening.

For women with large boobs, physical discomfort is real. Getting past the myths, boob size can affect a woman's daily physical well-being. For instance, many women with larger boobs experience physical discomfort, such as significant neck, shoulder or back pain and headaches. For some of these women, a better-fitting bra may be a simple solution. In addition, losing weight to decrease boob fat probably will help. Despite these efforts, some women find a reduction mammoplasty — surgery to reduce boob size — necessary to relieve pain and discomfort.

Boob size has a strong impact on a woman's mental well-being. After all, it's impossible to ignore the emphasis our culture places on boob size. From puberty to adulthood, a woman faces idealized norms and contemplates her potential to measure up. Biases exist against women with large boobs as well as small boobs. A girl or woman with larger boobs may deal with assumptions about her sexuality. A girl or woman with smaller boobs may feel inadequate. Recognizing that these external and internal pressures exist, we must encourage girls and women to become comfortable with their own bodies and dispel the myths.

The bottom line for all women is that you shouldn't expect more or less from your body because of your boob size. In particular, your ability to breastfeed and your risk of boob cancer, two of the most important health concerns, are unrelated to size.
