Hormone-sensitive cancers
What is Hormone-sensitive cancers?
Hormone-sensitive cancers are types of cancer that grow in response to certain hormones in your body. The most common examples include breast cancer and prostate cancer. These cancers have receptors on their cells that attach to hormones like estrogen, progesterone, or testosterone. When hormones bind to these receptors, they can signal the cancer cells to grow and multiply.
Not all breast or prostate cancers are hormone-sensitive, but many are. This matters because hormone-sensitive cancers often respond well to treatments that block or lower hormone levels. Understanding your hormone balance can help you and your doctor assess risk factors and catch problems early. Blood tests that measure hormone-related proteins give insight into how your body processes these powerful chemical messengers.
Sex hormone binding globulin, or SHBG, is a protein that carries hormones through your bloodstream. It binds to testosterone and estrogen, controlling how much of these hormones are available to your cells. Abnormal SHBG levels may signal an imbalance that could increase cancer risk. Regular testing helps you monitor these patterns before symptoms appear.
Symptoms
- A new lump or mass in the breast or testicle
- Changes in breast shape, size, or skin texture
- Nipple discharge or inversion
- Difficulty urinating or weak urine flow
- Blood in urine or semen
- Persistent pelvic or bone pain
- Unexplained weight loss
- Fatigue that does not improve with rest
Many hormone-sensitive cancers cause no symptoms in their early stages. This is why screening and blood tests are so important. By the time symptoms appear, the cancer may have already grown or spread. Regular monitoring helps catch changes when they are most treatable.

Causes and risk factors
Hormone-sensitive cancers develop when cells in hormone-responsive tissues grow out of control. Risk factors include age, family history, and inherited gene mutations like BRCA1 or BRCA2. Hormone imbalances play a major role. High levels of estrogen or testosterone over many years can increase the chance that cells will become cancerous. Obesity raises risk because fat tissue produces extra estrogen. Early menstruation, late menopause, and never having children also increase estrogen exposure in women.
Lifestyle factors matter too. Drinking alcohol, eating a diet high in processed foods, and lack of exercise can all affect hormone levels. Some studies link night shift work to higher breast cancer risk due to disrupted circadian rhythms. Hormone replacement therapy and certain birth control methods may also influence risk. Low SHBG levels mean more free hormones circulating in your body, which can fuel cancer growth. Testing your SHBG helps you understand your personal risk profile.
How it's diagnosed
Doctors diagnose hormone-sensitive cancers using imaging tests like mammograms, ultrasounds, and MRIs. If they find a suspicious area, they perform a biopsy. A biopsy removes a small tissue sample so lab specialists can check for cancer cells. If cancer is found, the tissue is tested for hormone receptors. This tells doctors whether the cancer responds to estrogen, progesterone, or testosterone.
Blood tests help assess your risk and monitor hormone balance. Rite Aid offers testing for Sex Hormone Binding Globulin, which shows how your body manages key hormones. Abnormal SHBG levels may signal increased cancer risk. Regular blood work gives you and your doctor data to guide screening decisions and lifestyle changes. Early detection makes treatment more effective and outcomes better.

Frequently asked questions
A cancer is hormone-sensitive when its cells have receptors that respond to hormones like estrogen, progesterone, or testosterone. These hormones bind to the receptors and signal the cancer cells to grow. Not all cancers in hormone-responsive organs are hormone-sensitive. Doctors test tumor tissue to determine if hormone receptors are present.
SHBG is a protein that binds to sex hormones and controls how much is available to cells. Low SHBG levels mean more free hormones circulating in your body. High levels of free estrogen or testosterone over time can increase the risk of breast and prostate cancer. Testing SHBG helps identify hormone imbalances early.
Blood tests cannot diagnose cancer directly, but they can reveal hormone imbalances that increase risk. Measuring SHBG shows how your body manages sex hormones. Abnormal levels may prompt your doctor to recommend screening tests like mammograms or prostate exams. Blood work is part of a proactive approach to prevention.
Risk is higher in people with a family history of breast or prostate cancer, especially if genetic mutations are present. Women who started periods early, entered menopause late, or never had children face higher exposure to estrogen. Men with low SHBG and high testosterone levels may have elevated prostate cancer risk. Obesity and alcohol use also increase risk.
Look for new lumps in the breast or testicle, changes in breast appearance, nipple discharge, or difficulty urinating. Bone pain, blood in urine, or unexplained weight loss can also be warning signs. Many hormone-sensitive cancers have no early symptoms. Regular screening and blood tests help catch problems before symptoms develop.
Most people benefit from checking SHBG once or twice a year as part of routine health monitoring. If you have risk factors like a family history of cancer or obesity, your doctor may recommend more frequent testing. Regular blood work helps you track trends over time. Catching imbalances early gives you more options for prevention.
Yes, lifestyle changes can significantly lower your risk of hormone-sensitive cancers. Maintaining a healthy weight, exercising regularly, and limiting alcohol all help balance hormones naturally. Eating plenty of vegetables, fiber, and healthy fats supports hormone metabolism. Managing stress and getting enough sleep also play important roles in cancer prevention.
Treatment often includes hormone therapy drugs that block hormone receptors or reduce hormone production. Surgery, radiation, and chemotherapy may also be needed depending on the cancer stage. Many people combine medical treatment with lifestyle changes to support recovery. Early-stage hormone-sensitive cancers often respond very well to treatment.
Hormone replacement therapy can increase the risk of hormone-sensitive cancers in some people. If you have a family history or other risk factors, talk to your doctor about alternatives. Some forms of HRT carry lower risk than others. Regular monitoring with blood tests helps your doctor assess whether HRT is safe for you.
Rite Aid offers blood testing for Sex Hormone Binding Globulin, which helps assess your hormone balance and cancer risk. You get tested twice a year at Quest Diagnostics locations nationwide. Results are delivered with clear explanations so you understand what your numbers mean. Regular testing gives you data to guide prevention strategies with your doctor.
