Which type of medicine kills cancer cells in the body, but also kills healthy cells?

The type of medicine that kills cancer cells but can also harm healthy cells is known as chemotherapy.

Chemotherapy works by targeting rapidly dividing cells, a characteristic of cancer cells; however, because some healthy cells in the body also divide quickly (such as those in hair follicles, the lining of the gut, and bone marrow), they can also be affected by the treatment. This is why chemotherapy often comes with a range of side effects, including hair loss, nausea, and an increased risk of infections due to its impact on healthy cells.

Overall, while chemotherapy is a powerful tool in the fight against cancer, its effects on healthy cells underscore the importance of carefully managing treatment to minimize side effects while effectively targeting cancer cells.
