Most cancer medications kill rapidly dividing cells, such as those in tumors. Two common side effects of cancer medications are hair loss and digestive tract upsets. Make a hypothesis about why these two side effects are seen in people taking cancer medications, and explain your reasoning.
Chemotherapy are drugs that are designed to kill rapidly dividing cells. Cancer cells proliferate at high rates thus formation of tumors becomes harder to control. Hair loss and digestive tract upsets are two of the most common side effects of chemotherapy. From that we can see some assumption like:
Chemotherapy drugs also attacks cells in the hair and in the digestive track thus affecting its normal metabolism.
Since chemotherapy kills fast growing cells, we can say that cells in the hair and in the digestive tract are fast growing.
Mitotic cells are cells that keep on growing and multiplying. Both cancer cells and cells in the hair and digestive tract are mitotic cells. Chemotherapy cannot distinguish which are cancer cells and which are not. Consequently, chemotherapy extinguishes all fast growing cells without discrimination.
