Understanding Stress Hormones: How Cortisol and PCOS May Fuel Breast Cancer
How Cortisol and PCOS May Fuel Breast Cancer
Did you know that stress hormones like cortisol could play a surprising role in breast cancer development? While we often think of stress as just a mental burden, it may have deeper, hidden effects on our health. In this blog, we’ll explore how stress might influence cancer growth and what steps you can take to help protect your long-term well-being.
Cortisol
Cortisol is a steroid hormone produced by the adrenal glands. Commonly called the “stress hormone,” cortisol plays a crucial role in the body’s response to stress. When you feel stressed, your brain’s hypothalamus sends signals to the pituitary gland. This gland then tells the adrenal glands to release cortisol.
The main functions of cortisol include:
- Raising blood sugar: This provides your muscles with quick bursts of energy to help you handle stressful situations.
- Slowing nonessential functions: Your body slows digestion and reproduction to focus energy on the stress response.
- Managing metabolism: Cortisol controls how your body processes fats, proteins and carbs, which can sometimes lead to weight gain.
- Lowering inflammation: Cortisol has anti-inflammatory effects, which help regulate your body’s immune response.
High cortisol levels happen when your body makes too much cortisol. This can lead to health problems, including weight gain (especially in the stomach), a round face (also known as moon face), acne, high blood pressure, and muscle weakness.
Polycystic Ovary Syndrome (PCOS)
Polycystic ovary syndrome (PCOS) is a common hormonal disorder affecting women of reproductive age. PCOS signs and symptoms include:
- Irregular Menstrual Cycles: Women with PCOS may have infrequent, irregular, or longer-than-usual periods.
- High Androgen Levels: Increased male hormones (androgens) can cause symptoms like excessive facial and body hair, severe acne, and thinning hair or baldness.
- Polycystic Ovaries: The ovaries can become enlarged and contain multiple small fluid-filled sacs or follicles around the eggs.

Managing Stress, PCOS, and Breast Cancer Risk
According to the American Cancer Society, breast cancer is the most common cancer in women in the United States. It is also the second leading cause of cancer-related deaths among women. High levels of cortisol can contribute to breast cancer growth by causing insulin resistance and weakening the immune system. Women with PCOS often experience chronic inflammation and insulin resistance, both of which are risk factors for breast cancer. Some studies suggest that PCOS may particularly increase the risk of estrogen receptor-positive breast cancer.
Managing stress effectively through techniques like mindfulness meditation, regular exercise, and a balanced diet can help reduce these risks. Emotional support from counseling or support groups fosters a sense of community and eases isolation. Managing stress early can improve PCOS symptoms, reduce breast cancer risk, and boost overall health.

Checking for PCOS and High Cortisol
Testing for PCOS usually involves the following steps:
- Medical History & Symptoms: Your health care provider will review your symptoms, menstrual patterns, and relevant medical history.
- Physical Exam: A physical exam, including a pelvic exam, can show signs of PCOS. This may include enlarged ovaries or other irregularities.
- Blood Tests: Blood tests to look at hormone levels, including androgens (male hormones) as well as blood sugar levels. These tests also help rule out other conditions that mimic PCOS.
- Ultrasound: A pelvic ultrasound checks for ovarian cysts and measures the thickness of the uterine lining.
