Cells exhibit an effect known as the Hayflick limit, which states that all cells can divide and reproduce only a limited amount of times. There are a few exceptions to that rule, as some cells known as immortal cells display no signs of aging and can be terminated only by outside factors, such as starvation or if their host dies.
Human germ cells (ovum and sperm) have no Hayflick limit. Many species of bacteria are considered immortal as they continue dividing until an outside force terminates them. Similarly, diseases of the cell cycle (such as cancer) are able to produce immortal cells as they grow and reproduce without limitations.

What does the presence of telomere caps give cancer cells?
Immortality. "A hallmark of cancer cells is immortality. The only cells in the body that are usually 'immortal' are germ cells and some stem cells. Other cells in the body are not immortal and can divide only a limited number of times before they either cease dividing or die. One block to unlimited cell division is a specialized structure at the end of each chromosome called the telomer." (Huether, McCance 2008, p 231)
