Why do I experience side effects?

Chemotherapy targets and destroys fast-growing cells. Since cancer cells are not the only fast growing cells in your body, chemotherapy also destroys some non-carcinogenic fast growing cells, including hair follicles, gastrointestinal lining, blood forming cells, skin cells and ovaries. This destruction or toxicity accounts for the most common side effects of chemotherapy, including hair loss, nausea, symptoms of menopause, pigment changes and changes in the red and white blood counts.
