Step 1: Understanding the Concept.
Combined oral contraceptive pills work mainly by stopping ovulation, but they also carry a set of non contraceptive benefits that go beyond just preventing pregnancy. The question asks which of three listed benefits are genuinely linked to pill use.
Step 2: Key Formula or Approach.
Each statement needs to be checked against the known non contraceptive protective effects of combined oral contraceptive pills, which affect breast tissue, tubal pregnancy risk, ovarian activity, and menstrual blood loss.
Step 3: Detailed Explanation.
Statement 1 says the pill protects against fibroadenoma. Users of combined oral contraceptive pills have a lower rate of benign breast conditions such as fibroadenoma and fibrocystic disease, likely because the pills keep hormone levels steady rather than letting them swing through a natural cycle. So statement 1 is correct.
Statement 2 says the pill protects against ectopic pregnancy. Because the pill stops ovulation, no egg is released to be fertilised, so the absolute risk of any pregnancy, including one implanting in the tube, falls sharply. So statement 2 is correct.
Statement 3 says the pill protects against ovarian cysts and iron deficiency anemia. By suppressing ovulation, the pill reduces the formation of functional ovarian cysts that form around a developing follicle or corpus luteum. The pill also makes periods lighter and more regular, which cuts the blood loss that leads to iron deficiency anemia over time. So statement 3 is correct.
Since all three statements hold up, the answer must include all of them rather than just two.
Step 4: Final Answer.
All three statements, 1, 2 and 3, are correct benefits of oral contraceptive pill use.
