Assessment of breast volume changes during human pregnancy using a three-dimensional surface assessment technique in the prospective CGATE study

Abstract

Pregnancies and breastfeeding are two important protective factors concerning breast cancer risk. Breast volume and breast volume changes might be a breast phenotype that could be monitored during pregnancy and breastfeeding without ionizing radiation or expensive equipment. The aim of the present study was to document changes in breast volume during pregnancy prospectively. In the prospective Clinical Gravidity Association Trial and Evaluation programme, pregnant women were followed up prospectively from gestational week 12 to birth. Three-dimensional breast surface imaging and subsequent volume assessments were performed. Factors influencing breast volume at the end of the pregnancy were assessed using linear regression models. Breast volumes averaged 420 ml at the start of pregnancy and 516 ml at the end of pregnancy. The first, second and third quartiles of the volume increase were 41, 95 and 135 ml, respectively. Breast size increased on average by 96 ml, regardless of the initial breast volume. Breast volume increases during pregnancy, but not all womens' breasts respond to pregnancy in the same way. Breast volume changes during pregnancy are an interesting phenotype that can be easily assessed in further studies to examine breast cancer risk.

How many cup sizes do you go up when you get pregnant?

How much bigger will my boobs get during pregnancy? As a fitter, we typically see pregnant women go up one band size and two cup sizes during pregnancy. The majority of the change occurs during the first trimester and is hormonally driven. These changes (1 band and 2 cups) are common with a weight gain of 25-35 pounds.

What trimester do breasts grow the most?

In the second trimester (weeks 13 to 27) , your breasts will get larger and heavier. You may need a larger bra that gives you more support. You will probably feel less of the tenderness and tingling from early pregnancy.

Do breasts go back to normal size after pregnancy?

In general, breasts will typically revert to their baseline volume when a mother reaches her pre-pregnancy weight. In many cases, however, breasts may change shape or size and look different for the long-term.

How many inches do breasts grow during pregnancy?

Why is it that people appear to get sick when the seasons change? Pincott said in her book that the breasts of a woman carrying a girl will increase about 3.2 inches (8 centimeters), while those of a woman carrying a boy will grow only 2.5 inches (6.3 cm).
