Hormone changes during the menstrual cycle may lead to breast swelling. More estrogen is made early in the cycle and it peaks just before mid-cycle. This causes the breast ducts to grow in size. The progesterone level peaks near the 21st day (in a 28-day cycle).
Cyclical breast/chest pain is typically experienced at particular times each menstrual cycle, and with specific symptoms: Breast/chest pain experienced 5–10 days leading up to the start of a period, that goes away after the period starts (1)
It can happen during puberty, pregnancy or from taking medication. In some cases, it occurs spontaneously and for no reason. Gigantomastia is also referred to as macromastia. However, macromastia is usually defined as excess breast tissue that weighs less than 5 pounds.
At the end of your period, your breasts may decrease in size. Experts at Healthline suggested that due to estrogen and progesterone bottoming out, your boobs deflate and return to their normal size.
Hormones are making your breasts sore.
Breasts become sore three to five days prior to the beginning of a menstrual period and stop hurting after it starts. This is due to a rise in estrogen and progesterone right before your period. These hormones cause your breasts to swell and can lead to tenderness.

Weight loss or weight gain
A woman's weight can have a big influence on the shape and size of their breasts. Weight affects the amount of fatty tissue within the breasts. Gaining weight increases the fatty tissue within the breast and results in breasts enlargement.
Breasts can feel heavy and sore for many reasons. Menstruation, pregnancy, and breastfeeding are common reasons, but infections and cysts may also cause discomfort. Less commonly, pain may stem from cancer.
The most common hormonal breast soreness comes from an increase in the level of oestrogen before a period. This causes milk ducts and glands to swell, trapping fluid in the breasts. Many women have tenderness or pain in the lead-up to a period, and sometimes right through it.
The most common type of breast pain is linked to the menstrual cycle. It is nearly always hormonal. Some women begin to have pain around the time of ovulation. The pain continues until the start of their menstrual cycle.
The breast tissue itself will go up and down in size and weight over time. Hormone changes, pregnancy, weight gain, and weight loss can all affect the internal structures of your breasts. Menopause can affect the fullness of breasts and reduce their volume.
No, it's not true. Touching or massaging breasts does not make them grow. There's a lot of wrong information about breast development out there. Some of the things you may hear are outright cons — like special creams or pills that make breasts bigger.
Lots of girls get aching in their breasts before their periods start. The aches are caused by a decrease in the hormones estrogen and progesterone, which are responsible for a girl's menstrual cycle. For some girls, these aches happen less often as they grow older. But that's not the case for everyone.
Breast buds usually grow about 2–2.5 years before your period starts, but if you notice your breast buds at an earlier age (when you're 8 or 9), it may take closer to three years for your period to start.
Many women notice their breasts become larger the week before menstruation. Breast swelling and tenderness before your period occur due to an increase in hormones during the menstrual cycle.
As you reach the age of 40 years and approach perimenopause, hormonal changes will cause changes to your breasts. Besides noting changes in your breasts' size, shape, and elasticity, you might also notice more bumps and lumps. Aging comes with an increased risk of breast cancer.
In women, fat also collects in the breasts, and at the sides of the breasts as side boob fat. Side boob fat is subcutaneous fat and the thickness of this layer will greatly vary from one person to another. There are two layers of fat in the body: Subcutaneous fat – the type of fat that's stored just below your skin.
The doctor added: “Other factors such as the skin around the breast can have a big impact on the way breasts look, as we get older our skin loses elasticity, which can change the appearance of breasts, with women in their 20s to 30s.” So basically, your boobs can suddenly grow if your hormones levels change!
In the early weeks of pregnancy, your breasts may feel fuller, sore and even tingly (weird, right?!). You may also notice that your bra doesn't quite fit like it used to. Because this is linked to hormone changes in your body, breast tenderness could also mean the start of your menstrual period.
First trimester breast changes
Breast tenderness is often one of the earliest symptoms of pregnancy. According to the National Institute of Child Health and Human Development , breasts may become sore, heavy, or tingly as early as 1–2 weeks after conception. The nipples may also feel sensitive or even painful to touch.
SORE, SWOLLEN AND TENDER BREASTS: If you experience that your breasts are becoming extra sensitive to any type of touch, it's a sign of pregnancy. This is due to the reason that during early stage of pregnancy, blood flow to your breasts increases, making the breast tissues more sensitive and swollen.
"If you don't wear a bra, your breasts will sag," says Dr. Ross. "If there's a lack of proper, long-term support, breast tissue will stretch and become saggy, regardless of breast size." Still, both experts agree that multiple factors play into if and when sagging (technical term: "ptosis") occurs, bra-wearing aside.
The nipples and the area around the nipples (areola) become darker and larger. Small bumps may appear on the areola. These bumps will go away after you have your baby. You may notice a yellowish discharge, called colostrum, from your nipples as early as the 16th to 19th week.
