The breasts are the tissue above the chest muscles and their growth begins at puberty and the signs of breast growth in their 20s continue in women. The main components of women’s breasts are the specialized glandular tissue that produces milk along with the fatty tissue. The amount of fat in the breasts determines their size. The breasts also contain blood vessels, lymphatic vessels, and lymph nodes, and connective tissue and ligaments support and shape the breasts.
The main physiological function of the breasts in women is to feed babies. The part of the breasts that produces milk is organized into 15 to 20 sections, called lobes. Each lobe consists of smaller structures called lobes where milk is produced. Milk travels through a network of small tubes called ducts. The ducts connect to each other and form larger ducts that eventually emerge from the skin of the nipples. The dark, pigmented area of skin around the nipple is called the areola.
The breasts are the only organs you are born with that dynamically change with each stage of life, from puberty to pregnancy, then involution, perimenopause, and finally menopause. These changes also cause a change in how your breasts look and how they feel.
Causes of breast growth in the 1920s
In most women, the breasts are fully developed by age 23. However, there may be certain reasons that cause breasts to increase in size during your 20s. The change in breast size can be temporary, lasting from a few days to a few weeks, and can sometimes be permanent.
The reason the breasts are believed to be fully developed by age 23 is because by this age, the changes caused by puberty have mostly stopped, and the breasts have filled with their part of fibrous tissue fatty. The abundance of connective tissue along with the intact strength of the suspensory ligament at this age causes the breasts to become thick and feel dense.
As breasts are made primarily of fatty tissue, an increase in weight in your 20s will cause the breasts to enlarge or enlarge. The opposite happens when you lose weight.
Most women get pregnant during their 20s, and this also causes breast enlargement along with weight gain caused by hormones released in the body during pregnancy. Also, the breasts increase in size as they prepare for lactation. The milk glands enlarge and fat accumulates in the breasts during pregnancy. These changes happen quickly, and you will see that your breasts have grown almost a cup size in the first 6 weeks of pregnancy. Pregnancy can cause the areolas to darken and the nipples to enlarge, but these two changes are usually temporary and return to the pre-pregnancy state after delivery.
The breasts enlarge and swell in some women during their menstrual cycle. However, the breasts return to their normal size once menstruation begins. The increase in the size of the breasts during the menstrual cycle is attributed to the increase in estrogen levels that causes the milk ducts in the breasts to enlarge, thus causing the breasts to expand and increase in size.
Regular use of oral contraceptives is another reason that can cause breasts to grow in size over 20 years. The increase in breast size caused by the use of oral contraceptives is again attributed to the hormonal changes caused by the use of these contraceptives.
Fibrocystic changes are another cause of breast growth in women in their 20s. These changes are harmless and can make the breasts feel lumpy and sometimes painful. Fibrocystic changes are caused by thickening of the breast tissue or the formation of fluid-filled cysts in the breast. Symptoms of fibrocystic breast changes include breast enlargement, lump formation, breast tenderness, and breast pain.
Breast Lumps – When to See a Doctor?
Lumps in the breasts are a common concern for women in their 20s. Lumps are usually caused by hormonal changes that lead to fibrocystic changes in the breasts, as mentioned above. But it is helpful to know that fibrocystic changes are not abnormal, although they can cause discomfort, and that the lumps that form are benign and do not increase the risk of breast cancer.
Sometimes women develop a single, firm, smooth lump that moves when pressed. This is called a Fibroadenoma, and it is a benign breast tumor made of fibrous and glandular tissue. The tumor is painless and grows at a slow rate. It can be surgically removed if it becomes painful and causes discomfort. A benign tumor can be easily differentiated from a cancerous one because a cancerous tumor is usually painless.
Women in their 20s and 30s generally do not have to worry about breast cancer, because breast cancer usually occurs in women over 40, however it is essential that young women ask a gynecologist and even should start regular clinical breast exams (CBE) in their 20s because early detection of breast cancer improves survival rates. CBEs must be done once every 3 years for women under 40.
Additionally, women in their 20s are advised to begin breast self-exams once a month, because the more often their breasts are examined, the more likely they are to recognize any breast abnormalities and the faster they will be able to search Medical help.
Causes of sudden breast enlargement
As mentioned above, breasts change dynamically throughout a woman’s life, and it is perfectly normal to experience changes in breast size during her lifetime. However, a sudden increase in breast size can sometimes be experienced, and causes include
- Sudden weight gain caused by hormonal changes and thyroid diseases
- Sexual relations: In some women, breast size increases only during intercourse due to increased heart rate and blood pressure at the time of intercourse. The veins enlarge and the breasts swell, giving the impression of enlarged breasts.
- Menstruation: Increased levels of estrogen and progesterone after the day of ovulation makes the breasts feel more tender and full. Also, water retention before periods may make your breasts feel larger. However, these changes are temporary, and breast size returns to normal once periods begin.
- Breast lumps also cause them to enlarge, and you should see a better doctor if you feel anything serious.
- Inflammatory breast cancer is another major cause of sudden breast enlargement. Breast cancer can make the breast swell, causing abnormal breast growth. Symptoms of breast cancer include swelling, tenderness, and redness of the breast. This can affect men as well and is equally dangerous for both genders.
The age limit for breast growth
As mentioned above, a woman’s breasts are fully developed by the age of 23, and any other signs of breast growth in their 20s in women are generally due to the causes and reasons discussed above. Most of the changes that occur in breast size are temporary and are due to physiological changes in the body, such as pregnancy and menstruation. Any permanent change in breast size should not be ignored, and taking a second medical opinion online is always advised if the changes are found to be immense and causing any discomfort.
