How come can the breast left and right differ in size?

The right and left breast size is different due to normal anatomic variations, hormonal changes during puberty, breast lumps, and breast cancer.

Breasts are an important part of a woman's body. Because, only through the breasts of a mother can you channel milk to the baby. Not only that, as a sexual organ, the form of breasts that are beautiful is desirable by not a few women to be more confident.

the breast is the tissue that lines the pectoral muscle. In women, the breast has mammary gland tissue and fat tissue.

The milk tissue in the breast is divided into 15 to 20 parts called lobes. In each lobe, there is a smaller structure called the lobule, where milk is produced. Milk will flow through the connected ducts and merge into a larger duct, which comes out of the skin on the nipple. Around the nipple is a dark area called the areola.

In addition, the breasts also contain blood vessels, lymph vessels, and lymph nodes.

The size of each breast is different, even the size of the left and right breasts are different. The difference in size is influenced by fat tissue. Reported by Healthline, "breast asymmetry" can be seen from the size, volume, position, or shape that is different from the others.

Breast asymmetry occurs in almost all women and is caused by trauma, puberty, or hormonal changes.

Why can it be different?

The article titled "Why Are My Breasts Uneven? 4 Reasons Boobs Can Be Asymmetrical ”published in Bustle in 2015 revealed four reasons why women's breasts differ in size, namely normal human anatomical variations, hormonal changes during puberty, breast lumps, and breast cancer.

The human body is indeed not symmetrical. From eyebrows to legs and arms, there are no similarities between the left and right sides. Similarly breast.

Hormonal changes during puberty also affect the difference in female breast size, because usually one of the breasts will grow earlier than the other.

An interview entitled "My Breast Are Different Sizes-Am I Normal?" Conducted by the University of Utah Health Hospital and Clinics with Dr. Kirtly Jones explained that no woman has symmetrical breasts. Jones explained that sometimes one breast grows faster than the other. The growth becomes abnormal when one breast does not grow at all.

"Breast sayu may hang slightly lower, there is no breast of young women hanging, but if one breast looks slightly lower than the other, that is also normal," Jones said.

Still according to Jones, normal breasts in the range of differences of 15 to 20 percent. Usually women will realize these differences when using a bra, because bras are designed for symmetrical breasts.

Other causes of asymmetry are lumps, namely tissue that grows in the breast. Some lumps can develop into cancer. Others are benign, or grow due to traumatic injuries.

Another thing that makes a difference in size is breast cancer. Must be aware if the asymmetry increases. Keep in mind, one symptom of breast cancer is a sudden change in the size, shape, and appearance of the breast.

In 1994, Anders Pape Moller, Manuel Soler, and Randy Thornhill released a paper entitled "Breast Asymmetry, Sexual Selection, and Human Reproductive Success" (PDF) based on research involving 172 women in Spain and the United States. The study shows that other factors that cause breast growth instability are breast size and age.

Apart from size and age, breasts can vary in size due to pregnancy and lactation. In these two processes, breast size will increase.

Breast Examination

If you feel the difference in your breast size is abnormal, hurry up and see a doctor. Later, the doctor will use a mammogram to evaluate the internal structure of the breast. As written in Healthline, if the mammogram test shows that your breasts are asymmetrical, then the doctor must do a follow-up examination to examine changes in shape and density.

The first step the doctor has to do is to compare the previous mammogram to determine changes in shape and density. If previously your breasts are symmetrical and turn out to be asymmetrical by continuing to experience increased differences, then the doctor will usually ask for breast ultrasound.

In this stage, the doctor will diagnose abnormal findings from mammogram images that cannot be clearly described. Through breast ultrasound, the doctor can determine whether there are benign lumps in the breast, fluid-filled cysts, and the potential for cancer.

The next stage is Magnetic Resonance Imaging (MRI) which is performed to detect breast cancer and other disorders. This stage will help examine the risk of breast cancer in people who have the potential to develop cancer genetically.

If the test results show that the breast is abnormal or there is an alleged appearance of cancer, then the next step is to do a biopsy. If the results of a negative biopsy, the doctor will ask you to diligently check the breasts.
