Last month, pink ribbons and awareness campaigns dominated the headlines, reminding us all about the importance of breast health. While screenings grab the attention, another factor that influences risk is, weight gain.

Many women don’t realise that carrying extra weight, particularly after menopause, can increase the likelihood of developing breast cancer. “Fat tissue isn’t just a passive storage of calories,” Dr Mansi Chowhan, Consultant Surgical Oncology, Fortis, Manesar, tells Moneycontrol. “It actively secretes hormones like estrogen, which can stimulate breast cell growth. Add inflammation and changes in insulin levels, and the risk climbs,” she adds.

Before menopause, the ovaries are the main estrogen factories. Once menopause hits, fat tissue takes over. Overweight women often have higher estrogen levels, which can spur breast cells to grow abnormally. Studies show that postmenopausal women with obesity face a 20–40 percent greater risk of developing breast cancer than those maintaining a healthy weight.

“Maintaining an optimal weight is one of the simplest yet most effective ways to lower risk,” says Dr Chowhan.

Obesity rarely comes alone. It’s often linked to poor diet, lack of exercise, alcohol consumption, and chronic stress — all contributors to cancer risk. The good news? These factors are changeable. Small, steady improvements in daily habits can yield significant long-term benefits.

FAQs on Weight Loss and Breast Cancer Risk

1. How does weight affect breast cancer risk?

Weight gain, especially after menopause, can increase breast cancer risk. Fat tissue secretes hormones like estrogen, which stimulate breast cell growth.

2. Why is maintaining a healthy weight important for breast cancer prevention?

Postmenopausal women with obesity have a 20-40% greater risk of developing breast cancer than those maintaining a healthy weight. Even modest weight loss can lower risk and improve wellbeing.

3. What lifestyle changes can help reduce breast cancer risk?

Eat a diet rich in fruits, vegetables, whole grains, and lean proteins; exercise for 30 minutes daily; limit alcohol; avoid smoking; and manage stress through mindfulness or yoga.

4. How does exercise help in reducing breast cancer risk?

Regular exercise helps regulate insulin and reduce inflammation, both of which contribute to lower cancer risk.

5. What are key practices for early detection of breast cancer?

Routine screenings and self-examinations are essential. Consult a specialist at the first sign of change in your breasts to ensure early detection.
