Does drinking milk increase size?

No, drinking milk does not increase breast size. Dairy milk indeed contains hormones such as estrogen, progesterone, and prolactin and it is also true that hormones affect breast size. But drinking dairy milk has no link with breast enlargement. 

A 2019 study probed a link between drinking excessive dairy milk and breast cancer on grounds that dairy milk contains hormones that elevate the levels of insulin-like growth factor 1, a growth hormone.

Raised insulin-like growth factor 1 levels in the blood are associated with an increased risk of breast, prostate, colorectal, and ovarian cancer. But the investigation on the link between cancer and drinking dairy milk is underway.

Do soy-based products increase breast size?

Certain plant-based compounds known as phytoestrogens, present in soy and soy-based products, behave similarly to estrogen. This is why most people are under the impression that eating soy-based products will magically enlarge their breasts which is false. 

The bottom line is that there is no scientific evidence that proves the association between breast enlargement and eating soy/soy-based products. 

What determines breast size?

The size of your breasts is genetic. By that, we mean both breast volume and bone structure are controlled by genes. 

Breast size changes with weight and age 

Other than genetics, weight, and age are the important determinants of your breasts size. Your breasts may experience sagging and changes in volume and structure after the onset of puberty. Moreover, weight gain or weight loss can affect your cup size and torso circumference.

Hormones and reproductive cycles affect breast size 

Puberty triggers the production of estrogen in the ovaries. This leads to fat accumulation, an increase in breast size. The production of estrogen and progesterone peaks just before your periods. This enlarges the breast ducts and milk glands, making your breasts look fuller.

Hormones such as estrogen, progesterone, and prolactin prepare your body for lactation during pregnancy, resulting in saggy or enlarged breasts, which is a common sign of pregnancy. On the other hand, breasts shrink during menopause due to a loss of elasticity.

Can diet impact your breast size?

Diet alone cannot increase your breast size. However, you may see an increase in breast size as you gain weight. This happens due to the accumulation of excess fat in your breasts. However, breasts are not the only organ that grows in size during weight gain.

Will exercise impact your breast size?

Strength training increases your muscle mass and tones your body. Regularly doing chest-specific exercises like chest press, pullovers, and fly’s can make a massive difference in the shape and size of your pectoral muscles or chest muscles.

Exercises that are effective in building stronger and fuller chest muscles include dumbbell chest press, Dumbbell pec fly, Alternating dumbbell press, pushups, Stability ball chest press, Up-down plank, Dumbbell pullover, etc.

How can you increase breast size?

Breast augmentation surgery is a very effective surgical procedure for increasing breast size. It involves putting implants in your breasts. Although proven effective, breast augmentation surgery comes with certain risks such as pain in breasts, bruising or bleeding, infection, leaking or rupture of implants, and scarring. 

The U.S. Food and Drug Administration (FDA) has indicated a link between breast implants and an increased risk of anaplastic large cell lymphoma. Before going under the knife, consult your doctor about the potential risks, cost, process, and results of breast enlargement surgery. 

Can the topical application of oils increase breast size?

Some people suggest massaging certain types of oils onto your breasts. These oils include almond oil, clove oil, coconut oil, emu oil, fenugreek oil, flaxseed oil, lavender oil, jojoba oil, olive oil, primrose oil, soybean oil, tea tree oil, and wheat germ oil.

These oils are claimed to eliminate stretch marks, prevent cancer, and soften the skin in addition to enlarging breasts. However, there is no scientific evidence to support these claims. 

How can birth control affect breast size?

The effects of birth control pills on your breast size are not permanent. Birth control pills contain synthetic estrogen and progestin that impact your breast size. 

This occurs due to fluid retention or temporary weight gain caused by the elevated level of these hormones in the bloodstream. Some rare side effects of birth control pills are high blood pressure, blood clots, heart attack, or a stroke.
