The fear that hormone replacement therapy in Chandler AZ, causes cancer is one of the most persistent concerns women raise — and one of the most misunderstood. Let us walk through what the research actually shows, because the relationship between HRT and cancer risk is far more nuanced than the headlines suggest.

HRT and Breast Cancer: The Real Numbers in Chandler AZ

The most cited concern is breast cancer. Here is what the current evidence says:

• Estrogen-only HRT (prescribed only for women without a uterus) is actually associated with a reduced risk of breast cancer in several large analyses.
• Combined estrogen-progestin HRT is linked to a small increased risk of breast cancer with long-term use — roughly equivalent to the risk of drinking one to two alcoholic drinks per day, or being overweight.
• The risk appears to be lower with bioidentical micronized progesterone compared to synthetic progestins.
• Most importantly, the absolute risk remains small. For context, out of 1,000 women using combined HRT for five years, approximately 4 additional cases of breast cancer may be detected — compared to 1 in 1,000 from alcohol and 6 in 1,000 from obesity.

What About Uterine (Endometrial) Cancer?

Estrogen alone, when taken by women who still have a uterus, does raise the risk of endometrial cancer — this is well established. For this reason, women with a uterus are always prescribed progesterone alongside estrogen. Progesterone protects the uterine lining and largely offsets this risk. Women who have had a hysterectomy do not face this concern and may take estrogen alone.

Ovarian Cancer

Some studies suggest a very small increase in ovarian cancer risk with long-term HRT use, but the absolute numbers are very low, and findings across studies are not entirely consistent. This is a topic worth discussing with your provider based on your individual and family history.

Cervical and Colorectal Cancer

HRT does not appear to increase the risk of cervical cancer. Interestingly, some research suggests combined HRT may actually reduce the risk of colorectal cancer, though this is not currently a reason to prescribe it.

Putting Risk in Perspective

Many factors in daily life carry health risks — physical inactivity, poor sleep, processed food, and chronic stress. HRT, when appropriately prescribed, is not categorically more dangerous than these common risk factors. The decision to use HRT should be based on a thorough, personalized risk-benefit analysis — not on fear.
