I'm 5'7, 116 pounds and currently have a 34 A/B cup. I read online that one way to find out how big I should go was the birdseed-in-a-nylon route. After doing cup to cc conversion it came out to around 400cc's. The problem is, wearing the birdseed around got my neck and shoulder's quite sore. I'm worried that it will be the same with implants. Has anyone else complained of back/neck pain after implants?
How Much Do 400 Cc Breast Implants Weigh?

Neck and back pain uncommon
400cc Saline Breast Implants Weighs 400grams
In this case a 400cc saline breast implant weighs 400 grams. There’s 454 grams in a pound so these implants weigh about .88 pounds. When silicone implants are used they weigh approximately 15% more than saline implants.
Implants in this size range are easily tolerated by most patients and aren’t associated with back or neck pain. This is especially true when implants are placed beneath the muscle. Under these circumstances, the muscle produces added support for the implant.
If you’re concerned about the weight of your breast implants, consultation with a board-certified plastic surgeon is appropriate. This surgeon should be able to discuss this issue and alleviate your concerns.
Any weight increase can pull you downward.
Perhaps you'll be happy with a smaller size, so the best way to know the right thing to do is to go in for a consultation with your Board Certified Plastic Surgeon.
Hope this helps.
Best of luck.

How Much do Breast Implants Weigh?
Dear Grand Canyon Girl,
Breast implants weigh about one gram per cc, so a 400 cc implant weighs about 400 grams, or 0.88 pounds. It is uncommon for breast implants to cause neck or back pain.

Breast Implant Weight
Hi Grand Canyon Girl, Interesting question and valid concern. First, 400cc implants weight less than a pound on each breasts. This is a substantial size implant, but if it's place correctly under the muscle, it should not feel heavy. They are deeper inside your body closer to your center of gravity so they won't feel the same as the testing sizers in your bra. I rarely see breast augmentation patients complain of back or neck pain unless they have a much older augmentation done over the muscle with very, very large saline implants.Most patients with these issues have naturally very large breasts, larger than any implant could make them. I might recommend doing your testing with sizers again, only using the Rice Test and see if you get a similar result. Good luck!
It's about 1 gram per cc
A 454cc implant weighs about a pound. (454 gms equals 1 pound).
Certainly, overly large implants can lead to upper back/neck discomfort, but not typically in the 400cc range. When implants are much larger (500-600cc+) it is more common.
400cc Silicone Breast Augmentation
In pounds this would be about 0.88 pounds per implant
Calculating The Weight Of Breast Implants
The weight of breast implants varies slightly based on whether they are saline or silicone. For saline implants, or water weight, 400cc roughly equals 400 grams or just under a pound. (specifically it is 1.7 lbs for both 400cc salinje breast implants) Silicone implants will weight slightly more than saline but only by about 15%. (1.9 lbs for both 400cc silicone implants) For implants of this size, I have never seen or heard of a patient complaining of symptoms that are more typical of large breast reduction patient discomfort. This is because in breasts that sag or hang, they pull on the neck and back just like a rope around your neck with small weighted sacs attached to them. In the breast augmentation patient, the implants and breasts are up on the chest wall and not suspended or hanging. Pain, shoulder and neck pain from breasts is as much as their position on the chest wall as it is their size and weight.
Weight of an implant
Thank you for a very interesting question. In short, for the same volume, the implant is likely to be lighter than birdseed, i.e. birdseed will be denser than silicone/saline implants.
I am surprised to hear about soreness of neck and shoulder. I cannot recall a patient ever complaining about this after even larger implants. I can only suggest that you try with 400g of weight on each side and if you still have any problem, consider smaller implants.
