What is at higher risk of developing ovarian cancer?
Author : Dr. Anuj Suketu Shah | Published On : 14 Oct 2026
Ovarian cancer does not have one single cause, so doctors look at which conditions, habits, and life events push the chances higher. Some of these are present from birth, such as inherited genes. Others build up over the years, such as hormone exposure or long standing medical conditions. Understanding what raises risk gives women a practical way to judge their own situation and decide when to speak to a specialist. Many people looking for Ovary Cancer Treatment in Ahmedabad start by asking whether something in their health or family history could have contributed, so this article explains the main factors in plain terms.
Inherited gene changes
The strongest known factor is a harmful change in certain genes passed down in families. The BRCA1 and BRCA2 genes normally repair damaged DNA, and when they are faulty, cells can grow out of control more easily. Women with these changes have a far higher lifetime chance of ovarian cancer than the general population. Lynch syndrome, an inherited condition that affects the bowel, uterus, and ovaries, also raises the risk. These changes can be passed on by either parent, which is why a father's family history of breast or ovarian cancer matters as much as a mother's.
A strong pattern of cancer in the family
Even without a known gene change, a family history of ovarian cancer raises risk. The concern grows when several relatives are affected, when cancers appear at a young age, or when different cancers such as breast, bowel, and uterine cancer cluster together. Doctors often use this pattern to decide whether genetic testing is worthwhile.
Advancing age
Age works quietly in the background. The ovaries and the cells around them are exposed to many years of hormonal changes and cell division, and each division carries a small chance of error. For this reason, the likelihood rises steadily with age, and most diagnoses happen after menopause. Women in this stage of life should treat new and lasting abdominal symptoms as worth checking.
Hormone exposure across a lifetime
Hormones shape the ovaries throughout life, and the total amount of exposure appears to matter. Women who started periods early or reached menopause late have more years of ovulation. Those who have never been pregnant also experience more ovulation cycles over time. In contrast, pregnancy, breastfeeding, and long term use of birth control pills are linked with lower risk. Hormone replacement therapy taken for many years after menopause has also been associated with a small rise in risk, so the decision to use it should be made carefully with a doctor.
Endometriosis
Endometriosis happens when tissue similar to the lining of the womb grows outside it, sometimes on the ovaries themselves. Over time, this tissue can cause inflammation and cysts. Women with endometriosis have a higher chance of certain ovarian tumours, particularly endometrioid and clear cell types. The overall chance remains low for most, but women with long standing disease should keep regular follow up and mention any change in cyst size, pain pattern, or bloating.
Previous cancer of the breast
Women who have already had breast cancer face a higher chance of ovarian cancer, partly because both cancers can share the same gene changes. If breast cancer occurred at a young age, affected both breasts, or was of the triple negative type, genetic counselling is often advised to check for inherited causes.
Body weight and lifestyle
Being overweight or obese has been linked with a modestly higher risk, particularly when weight gain began early in adult life. Smoking is associated with a higher chance of the mucinous type of ovarian tumour. A healthy weight, regular movement, a balanced diet, and avoiding tobacco support general health and may help reduce risk, though they cannot remove it entirely.
Fertility treatment
Research on fertility medicines has given mixed answers, and any extra risk appears small. Women who have had fertility treatment should talk through their own situation with a doctor rather than rely on general figures.
What does not clearly raise risk
Many women worry about everyday exposures. Evidence for talc powder and some other environmental factors has been inconsistent, and firm conclusions cannot be drawn for an individual woman. It is better to focus on well established factors such as family history, genetics, and medical conditions.
Warning signs that should never be ignored
Because there is no reliable screening test for the general population, symptoms are the best early clue. These include bloating that does not settle, pain in the pelvis or abdomen, feeling full after eating very little, a frequent need to pass urine, a change in bowel habits, and unexplained tiredness or weight change. Anyone with these symptoms for more than two or three weeks should see a doctor, and the need is more urgent for women in higher risk groups.
Steps women can take
First, find out your family history on both sides and share it with your doctor. Second, ask about genetic counselling if close relatives have had ovarian, breast, bowel, or uterine cancer. Third, attend regular gynecological check ups and report changes quickly. Fourth, discuss preventive choices with a specialist if you carry a high risk gene change. In selected women who have completed their families, preventive removal of the ovaries and tubes may be considered after careful counselling.
Speaking to a specialist
Risk is personal, and a proper assessment looks at the whole picture rather than a single factor. At his clinic, Dr Anuj Suketu Shah provides detailed evaluation and surgical care for women with gynecological cancers, guiding patients through testing, diagnosis, and treatment decisions.
