An individual woman's body has to be considered before performing a cosmetic surgery procedure such as breast augmentations.
This is according to Dr Christopher Craft, a cosmetic surgeon who has trained in general and plastic surgery.
Dr Craft specialists in skin and breasts and has observed that too large a breast augmentation can lead to health problems.
"Going too big can lead to back pain, skin damage and premature descent," he said.
"I try to talk to my patients so they understand the long term."
The surgeon added: "Gravity always wins."
When determining the best size of breast for an individual woman it is necessary to take into account the amount of tissue already present in the breast and the skin laxity of the person in question, he noted.
Earlier this year, the British Association of Aesthetic Plastic Surgeons reported that breast augmentation is still the most popular cosmetic surgery, with a total of 8,565 procedures performed last year.
