When you reach the teen years, your breast will exhibit visible signs of development. It happens when the ovaries begin to make and release estrogen. At that point, the collection of connective tissue starts, and the breast grows. Likewise, the duct system also grows. During the breast changes, armpit and pubic hair also grow.

When the menstruation and ovulation begins, the breast also matures and starts with the secretory glands formations found at the ends of milk ducts. The duct and breast systems continue maturing and growing of lobules and glands. Each woman has various rates of breast growth.

Stage 1 – The nipple tip raises

Stage 2 – Nipple, breast, and buds appear and rise. The areola (the dark area of skin) gets larger.

Stage 3 – The breast grows slightly larger

Stage 4 – The nipple and areola rises and becomes the second mound.

Stage 5 – At this time the adult breast becomes mature and the breast turns rounded while only the nipple becomes raised.

What Happens To The Breast During The Menstrual Cycle?

The following occurs in the breast during the cycle of menstruation

Your breast turn lumpy

In your first days of menstruation, you may feel a nodular and uneven feeling in your boobs. According to Sara Gottfried, MD, the Hormone Cure author, the breast becomes lumpier when the milk glands grow larger to prepare for a possible pregnancy. This bumpy feeling is temporary and will become smooth once the body realize that there isn’t a pregnancy.

They become perky

Estrogen levels rise as you go near ovulation (occurs during day twelve and also named as follicular phase). The Journal of Ultrasound Medicine makes your breast appear buoyant. The hormone makes your skin elastic.

Breasts turn lopsided

Research from the Ethology and Sociobiology journal discovered that a low estrogen before the week of your menstruation can make your breast lopsided that is – one breast is large than the other. This asymmetrical breast reverts to normal once your menstruation starts.

Breast become firm and full

During the phase after ovulation that is from the fifteenth day until the end of the cycle, your breast size enlarges. This happens when the progesterone rises. Your breast may appear veiny, swollen, and tender to touch.

What Are The Stages Of Breast Development

Breast development stages comprise pre-birth, puberty, pregnancy, and menopause stages.

  • Birth stages – By the time a person is born, he/she will form milk ducts and nipples. In females, breast grows larger.
  • Puberty stage – Puberty starts in girls from 8 years of age and 13 years. When your ovary makes estrogen, your breast tissue gains more fat. The extra fat can cause your breast to become larger. The milk ducts grow and ovulation starts. These milk ducts become glands or secretory glands.
  • Menopause stage – Around the age of 50, most women reach the menopausal stage. At this time, your body will not make estrogen that can affect breasts. They decrease in size and elasticity that leads to sagging. On the other hand, if you got hormone therapy, you may experience menstrual cycle symptoms.

Ensure that you see a doctor if you find a lump that doesn’t change or gets bigger during your monthly cycle. That could be an infection sign which can need medical attention. Symptoms include:

  • Breast swelling
  • Nipple discharge that is not milk
  • Nipple pain
  • Skin irritation in the breast
  • A nipple that turns inwards
