Can you take progesterone if you have breast cancer?

Progestin use in breast cancer survivors is associated with an increased breast cancer risk compared with its non-use [4]. However, outside pregnancy, progesterone endogenously produced or exogenously administered does not have a cancer-promoting effect on breast tissue.

What role does progesterone play in breast cancer?

Both the rapid actions and the transcriptional activity of PR-B contribute to breast cancer cell proliferation in response to progesterone. Progesterone/PR act in concert with mitogenic protein kinases and cell-cycle mediators to induce regulation of PR target genes and proliferative responses.

Does progesterone increase breast cancer risk?

Higher circulating progesterone levels were associated with a modestly increased breast cancer risk, with a hazard ratio of 1.16 (95% CI, 1.00-1.35) per SD of serum progesterone.

Does taking progesterone increase cancer risk?

The investigators found that postmenopausal women with higher circulating progesterone levels experience a 16% increased risk of breast cancer. Additionally, associated risk from progesterone seemed to be modified by estradiol concentrations.

Can natural progesterone cause breast cancer?

What types of cancer does progesterone cause?

Studies have also shown that a woman’s risk of breast cancer is related to the estrogen and progesterone made by her ovaries (known as endogenous estrogen and progesterone). Being exposed for a long time and/or to high levels of these hormones has been linked to an increased risk of breast cancer.

How can progesterone cause breast cancer?

Progesterone inclusion during hormone therapy intervention leads to a persistent increase in breast cancer risk after intervention and leads to the development of hormone receptor–negative tumors in addition to those that are hormone receptor positive.

What are symptoms of low progesterone?

Symptoms of low progesterone in women who aren’t pregnant include:

  • headaches or migraines.
  • mood changes, including anxiety or depression.
  • irregularity in menstrual cycle.

Does progesterone cause breast lumps?

What are the dangers of taking progesterone?

However, progesterone can cause many side effects including stomach upset, changes in appetite, weight gain, fluid retention and swelling (edema), fatigue, acne, drowsiness or insomnia, allergic skin rashes, hives, fever, headache, depression, breast discomfort or enlargement, premenstrual syndrome (PMS)-like symptoms, …
