If cells are damaged or diseased, it can lead to dysfunction of tissues, organs, and organ systems. Some possible consequences include impaired tissue function, organ failure, or disruption of bodily functions. The severity and specific effects depend on the type and extent of the damage or disease.
It is like standing next to a star. Sunbeds expose you to ultraviolet radiation and this can ionise your cells and damage them as it passes through your body. This is potentially harmful if too many cells get damaged as they can become cancerous and cause a tumour which can kill you.
Stem cells can repair a damaged heart by turning into new cardiac cells to replace the damaged tissue.
Mitosis allows growth and replaces worn out or damaged cells.

It will depend on which cells are damaged and the extent/nature of the damage. Sublethal damage is when the damage does not kill the cell. This may result in the accululation of water or another substance (eg. hydropic or fatty degeneration). If the cell is lethally damaged, it will undergo necrosis. If large areas of cells are damaged, the surrounding cells usually react by undergoing mitosis (depending on the tissue type in question). If large enough areas undergo irreversible damage, the tissue will become necrotic and organ disease or failure may result.

Damaged cells are usually harmless. The body will reject those cells or repair them. You can read more on the added link.
The difference between ultraviolet radiation and ultrasound is how they react when inside the body. Ultraviolet radiation attacks the cells and destroys cells that are harmful to the body. Ultrasound is merely a viewing device. Ultrasound is used to detect abnormalities in the body.
