The chest is mainly composed of adipose tissue, breast tissue and connective tissue. Its softness is closely related to the following structures:
| Organization type | Proportion | Functional impact |
|---|---|---|
| adipose tissue | 60-80% | Determines softness and elasticity |
| Breast tissue | 15-25% | Hardening during breastfeeding |
| connective tissue | 5-15% | provide support |
2. Key factors affecting breast softness
| factors | Influence mechanism | Data reference |
|---|---|---|
| Hormone changes | Estrogen promotes fat deposition, and progesterone promotes breast hyperplasia | Hardness varies up to 30% during menstrual cycle |
| Growing older | Loss of collagen and relaxation of suspensory ligaments | After the age of 40, softness increases by 25% |
| Breastfeeding status | Breast alveolar overflow increases hardness | Hardness increased by 40-60% during lactation |
