Cancer therapy typically involves surgery, radiation, chemotherapy, targeted therapy, and immunotherapy.
Chemotherapy drugs target rapidly dividing cells but can also affect normal cells, leading to side effects.
Targeted therapies are designed to interfere with specific molecules involved in cancer growth and progression.
Phases of cancer therapy include induction (to reduce tumor burden), consolidation (to eliminate remaining cancer), and maintenance (to prevent recurrence).
Common side effects of cancer treatments include nausea, fatigue, hair loss, and increased risk of infection.
