###Human: Is it advisable to use birth control pills if I have a lung cyst? ###Assistant: Hi. Birth control pills generally do not affect the lungs. Still, confirm with your pulmonologist to double check. Follicle cysts subside in three months after the oral pills use. You can start the pills from the first day of periods itself, and continue the packs back to back, no gaps. First 24 tablets are hormonal ones, while the last four are placebo, giving you a hormone-free interval for withdrawal bleeding.
