Most breast cancer happens in women with no risk factor beyond being female and older. Here is what the NHS, CDC and WHO list as raising risk, what the research does not support (deodorant, abortion, bras), and what to do about a family history.
Not in any simple way. The NHS says nearly all women produce enough milk, and that supply follows how often the baby feeds. Research points to glandular tissue and milk removal, not outward cup size, and one study saw breasts shrink back while still making a substantial amount of milk.
Probably not in the way the story goes. Larger studies of women living together found no syncing, and researchers suggest ordinary variation in cycle length makes periods drift together and apart by chance.
It is less likely, but none of the health sources we read call any part of the cycle safe. Sperm can survive for days and some women ovulate early, so pregnancy soon after a period is possible.
Yes. The NHS says you can get pregnant from 3 weeks after birth, even while breastfeeding and before periods return. Breastfeeding only works as contraception under strict conditions, for up to 6 months.
Breasts change at every stage of life, mostly because of hormones: puberty, the monthly cycle, pregnancy, breastfeeding and menopause. Here is what the NHS and ACOG describe at each stage, and which changes to get checked.
BV is a common imbalance of vaginal bacteria. It often causes thin grey discharge with a fishy smell, but half of women notice nothing. It is treated with antibiotics and often returns.
There is no good evidence that fenugreek, soy or breast enhancement pills make breasts bigger. A review of these products found no published clinical trials and raised safety concerns, and the NHS warns herbal medicines can interact with common medicines, including the pill.
Yes. ACOG says pregnancy can happen even the first time you have sex, because what matters is whether sperm meets an egg, not how many times you have had sex before.
Chlamydia is a common STI that usually causes no symptoms. It is found with a urine test or a swab and cured with antibiotics. The NHS suggests testing once a year or with a new partner.
Bleeding after sex is usually not serious, but the NHS says always get it checked. Common causes are cervical ectropion, polyps, vaginal dryness and infections such as chlamydia.
Bleeding between periods is usually not serious, but the NHS says to always get it checked. Common causes are hormonal contraception, polyps or fibroids, and infections like chlamydia.
Most breast lumps are harmless, according to the NHS and the CDC, but you cannot tell which kind by feel, so every one should be checked by a GP. Here is what they can be and what happens at the appointment.
The research we found does not support a link between bras and breast cancer. A large case-control study found no aspect of bra wearing, underwire included, was linked to breast cancer, and neither the NHS nor the CDC lists bras as a risk factor.
Most breast pain follows the menstrual cycle and, on its own, is not usually a sign of cancer. Here is what the NHS and ACOG say helps, what the evidence says about evening primrose oil, and when to see a GP.
We found no study showing that push-ups or chest exercises make breasts bigger. Breast tissue sits in front of the chest muscle, not inside it, breasts develop at puberty, and one twin study found cup size is largely inherited.
Adenomyosis is when the womb lining grows into the muscle of the womb wall, often causing painful, heavy periods. It is different from endometriosis, though many women have both, and treatments can help.
Thrush is an overgrowth of a yeast that already lives in you, and it is not classed as a sexually transmitted infection. What the NHS, CDC and ACOG actually say about what causes a flare, what treatment involves, what recurrent really means, the condom warning almost nobody mentions, and why untreated thrush does not become the dangerous kind. Every claim linked to its source.
