For some, suddenly gaining breast weight or losing it rapidly might mean a rise or fall in your estrogen and progesterone levels. If you’re pregnant or nursing, that’s to be expected, but it might be telling for your health in other ways. For example, if you’re not menopausal or losing weight but your breasts seem to be shrinking, you might want to be tested for polycystic ovary syndrome (thought to be caused by higher levels of testosterone). If you suspect that you’ve gained or lost breast weight, the actual numbers are good to know.

The most intuitive method is just guessing by cup size. It won’t always be the most accurate method, because of course breasts are each made differently. Shape, size, and even two women with the same cup size may have breasts which weigh differently. The measurements below (breast weight by cup size) were calculated using the average underwire size and the cup diameter of the more common US sized bra brands.

The water displacement method is a bit more awkward, but perhaps the most accurate way to weigh your breasts.

Okay lets start with what you'll need:

• A kitchen scale
• A tray with a sizable lip
• A large bowl(has to be big enough to fit one of your breast)
• A pad and pen(you'll have to do a little math)
• A towel

Okay now were ready let's give it a try:

• Step 1: Measure the weight of the tray
• Step 2: Put the bowl on the tray and fill bowl with water completely to the rim(Use a glass or cup to fill the bowl)
• Step 3: Now place you breast in the bowl of water, make sure it is fully submerged. Your boob will push out the water onto the tray
• Step 4: Take just the tray with the water that your breasts pushed onto it and weigh it
• Step 5: Subtract the weight of the tray with the water with the weight of just the tray and we are almost done
• Step 6: Now take that weight you just figured and multiply by 0.9 Why you may ask?....Because breast tissue has a different weight by volume then water
• Step 7: Repeat for you other boob if you like. (Remember your breasts are different sizes)

Some amount of pain from heavy breasts is natural. For instance, women with heavier breasts tend to experience more back pain -- there's more to carry! If you're athletic, heavy breasts can be a particular problem as they tend to bounce and, again, add more pressure as you work out. Fortunately, there are ways to help lessen some of the pain and stress from heavy breasts. Finding a strong and supportive sports bra for larger breasts is a MUST!!! Reducing bounce is essential in fuller busts to prevent damage to the ligaments and stretching of the boob later in life. Here are some great options:

Mostly, it comes down to having the correct cup size. Studies show that 80% of women are wearing the wrong bra size, which can put undue stress on your back and shoulders even if you don't have heavy breasts. Check out our sizing guide !!   Having a secure back band and supportive sides can also help take the pressure off of your back.  Sports bras such as Anita's Maximum Support Sport Bra or full-cup bras like the Goddess Keira line can offer the support that more well-endowed women need.
