The main risk factors contributing to the development of cervical cancer are as follows:

1. HPV Infection: Human Papillomavirus (HPV) is the most significant risk factor for cervical cancer. HPV infection is a sexually transmitted viral infection.
2. Sexual Activity: Initiating sexual activity at an early age or having multiple sexual partners can increase the risk of cervical cancer.
3. Smoking: Smoking increases the risk of cervical cancer. Women who smoke have a higher risk of cancer.
4. Weak Immune System: Individuals with a weakened immune system are at a higher risk of HPV infection progressing to cancer.
5. Family History of Cervical Cancer: Having a family history of cervical cancer can increase the risk of developing the disease.
6. Poor Nutrition: Inadequate consumption of fruits and vegetables can increase the risk of cervical cancer.
7. Oral Contraceptive Use: Long-term use of oral contraceptives (birth control pills) can increase the risk of cervical cancer.
8. Birth Control Methods: Incorrect or long-term use of birth control methods can increase the risk of cervical cancer.
9. Multiple Pregnancies: Having multiple pregnancies can increase the risk of cervical cancer.
10. Early Age at First Pregnancy: Undergoing the first pregnancy at an early age can increase the risk of cervical cancer.

To reduce the risk of cervical cancer, regular doctor check-ups, HPV vaccinations, a healthy lifestyle, and informed sexual activity are important. It is crucial for every woman to undergo regular Pap smear tests for early diagnosis and treatment.
