The breasts are mostly made up of adipose tissue, or fat. Losing body fat can reduce a person's breast size. People can lose body fat by using up more calories than they eat, and by eating a healthful diet. A low-calorie, highly nutritious diet can indirectly help to shrink breast tissue.
How Weight Affects Breast Size. Weight loss or weight gain won't dramatically affect cup size, says Daniel Maman, MD, a board-certified plastic surgeon in Manhattan who sees several patients for breast surgery every day.

Women with a genetic predisposition to high BMI are likely to have a larger breast size and a lower risk of breast cancer.
With age, a woman's breasts lose fat, tissue, and mammary glands. Many of these changes are due to the decrease in the body's production of estrogen that occurs at menopause. Without estrogen, the gland tissue shrinks, making the breasts smaller and less full.
As females get older, their bodies start to produce less of the reproductive hormone estrogen than before. Estrogen stimulates the growth of breast tissue, while low levels of this hormone cause the mammary glands to shrink.
Gigantomastia or breast hypertrophy is a rare condition that involves developing extremely large breasts due to excessive breast tissue growth. It affects people assigned female at birth. If you have gigantomastia, you'll experience rapid and disproportionate breast growth.
In general, breast development begins between the ages of 8 and 13. A girl's breasts are typically fully developed by age 17 or 18, however in some cases they can continue to grow into her early twenties.
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.
Roughly half of women ages 40 to 74 have dense breasts. The breasts of aging women become less dense over time, although nearly a third of all women age 65 and older still have dense breasts, Braithwaite said.
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.
Signs of Breast Fat Necrosis
Breast fat necrosis typically feels like a round, firm lump to the touch. Some women experience tenderness, bruising, or dimpling in the area where the breast fat necrosis appears. Sometimes it can pull in the nipple.
"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.
"We know that omega-3s help decrease inflammation in the body," she says. "You can also eat walnuts and seeds if you want a non-animal source." And just like olive oil, eating more omega-3s may also be linked to a reduction in breast density, according to a 2014 study in Cancer Causes & Control.
Breast Changes During Your 30s
In your 30s, breasts still retain much of their elasticity and firmness. However, it is not uncommon for some women to become prone to fibrocystic developments after this point. This refers to benign lumps that appear in the breasts, often related to hormonal fluctuations.
Moreover, women with fatty breasts are at low risk of breast cancer, regardless of age, menopausal status, family history of breast cancer, history of prior breast biopsy, and postmenopausal hormone therapy use [3, 11].
No — breast density is determined by genetics, age, menopause status and family history. Weight gain and certain medications can also influence your breast density. Though your breast density can't be changed, information is power.
The breasts can enlarge after menopause due to the hormone oestrogen levels going down. When the breasts go through an " involution " process, the milk glands shut down, and the tissue is replaced with fat.
The main reasons why women's breasts get bigger as they get older are: Weight gain or weight redistribution. Fluctuating hormone levels due to menopause.
As your milk system starts to shut down, glandular tissue in your breasts shrinks. That causes them to become less dense and more fatty, which can lead to sagging. You may also notice that your breasts aren't as full as they used to be, and their size may change.
For people taking estrogen as part of their gender transition, breast growth typically begins within three months of starting GAHT. Breast growth or changes in sensation tends to increase dramatically within the first six to twelve months.
