For women, secondhand smoke can be nearly as harmful as direct smoking. Studies show that inhaling tobacco smoke regularly:

Weakens the immune system, making it harder for the body to fight off HPV (the main cause of cervical can.cer).
Disrupts the reproductive system, raising the risk of complications such as premature birth.
Increases the likelihood of developing breast can.cer, respiratory illnesses, and cardiovascular disease.
In short, every cigarette a husband lights up also increases his wife’s risk of serious health conditions — including cervical can.cer.

Condoms are among the most effective ways to reduce the risk of sexually transmitted infections (STIs), including those linked to cervical can.cer. When used correctly, condoms are up to 98% effective in preventing transmission.
