A lipoma is a non-cancerous (benign) fatty lump that develops when fat cells grow too much. Lipomas are usually harmless and slow-growing, and they often feel doughy and move easily when pressed with a finger. They can appear anywhere on the body where there are fat cells, but are most common on the neck, chest, back, shoulders, arms, and thighs. Lipomas can also grow inside the body, so you might not be aware they're there.

Liposuction is a cosmetic surgical procedure that removes excess fat from specific areas of the body using suction. It's designed to enhance body proportions and create a more defined silhouette by targeting localised fat deposits that are resistant to diet and exercise. 

Liposuction is not a weight-loss method and does not remove fat from other parts of the body, such as visceral fat from around your organs.
