Tissue Expanders A tissue expander is a device that is made from elastic silicone rubber. During the mastectomy‚ this balloon-like device is placed after the surgeon removes skin and tissue to allow for placement of the tissue expander beneath the remaining muscle and skin of the patient’s chest.

human body is summarised as follows: Cells—> Tissues—> Organs—> Systems—> Organism. The same type of cells which carry out a specific function are organised into a tissue. For examples‚ a group of muscle cells form a muscle tissue while a group of nerve cells form a nerve tissue. They are organised to work together to perform specific functions as the result of cells in the human body do not work individually. An organ is a group of tissue that cooperates to carry out a specific life process
