Cervical cancer is one of the most common health threats faced by women worldwide, and many are shocked to learn that some of the risk factors can actually come from their own husbands’ habits. What may seem like ordinary or even “normal” behaviors can quietly increase a woman’s chance of developing this life-threatening disease.

Below are three selfish habits that husbands need to stop immediately — not only to protect their wives’ health but also to safeguard the well-being of the entire family.

1. Frequently Smoking

Smoking is one of the most widespread addictions among men, with countless individuals lighting up several times a day or even finishing an entire pack daily. While some claim they smoke to relieve stress, cope with sadness, or simply out of habit, this behavior has devastating consequences.

The most alarming fact is that secondhand smoke is nearly as harmful as direct smoking. Women who are regularly exposed to it face a much higher risk of serious health conditions, including cervical cancer, breast cancer, premature birth, and infertility. Prolonged exposure also contributes to cardiovascular disease, chronic respiratory problems, weakened immunity, and even early aging.

In short, a man’s cigarette habit doesn’t just damage his own body — it silently endangers the life and health of his wife, children, and everyone living under the same roof.

2. Refusing to Use Protection During Intimacy

One of the most effective methods of preventing sexually transmitted infections (STIs) is the use of condoms. Studies confirm that when used correctly, condoms can provide up to 98% protection against diseases such as HPV — a virus closely linked to cervical cancer. Unfortunately, many men stubbornly refuse to use them, often citing discomfort or reduced pleasure, without realizing the long-term risks they are imposing on their partners.

Some women turn to hormonal contraceptives such as pills, injections, or implants instead. However, research from the University of Copenhagen revealed a worrying statistic: long-term use of hormonal contraceptives can raise the risk of breast cancer by up to 38%. Findings published in the New England Journal of Medicine further indicate that women who rely on these methods for under a year face a 9% higher risk, but with 10 years of continuous use, that risk escalates sharply to 38%.

This means that a husband’s refusal to take responsibility for safe intimacy not only puts his wife at risk of infections but can also indirectly push her toward dangerous alternatives that carry their own serious health consequences.

3. Demanding Intimacy During Menstruation

Another selfish habit that many women quietly endure is being pressured into intimacy during menstruation. At this time of the month, a woman’s body is in a highly vulnerable state — the cervix is slightly open, which makes it much easier for harmful bacteria to enter and cause infections.

Dr. Trần Ly Hồng of the First Affiliated Hospital of Fujian Medical University warns that engaging in intercourse during menstruation significantly increases the risk of bacterial infections, pelvic inflammatory disease, and other gynecological conditions. If left untreated, these issues can progress into more severe health complications, including cervical cancer.

Therefore, women must set firm boundaries during their menstrual period and husbands need to respect them. What may appear to be a “small request” can have lifelong consequences for a woman’s health if ignored.
