Estrogen and the ERs are implicated in breast cancer, ovarian cancer, colon cancer, prostate cancer and endometrial cancer - Advanced colon cancer is associated with a loss of ER-β, the predominant ER in colon tissue, and colon cancer is treated with ER-β-specific agonists.

A test result of ER-positive (ER+) - means that ERs are “over-expressed” and that estrogen is causing a tumor to grow. ER+ tumors are slightly slower-growing than ER- tumors, and the cancer should respond well to hormone suppression treatments.
▪ 0 is no receptors found,
▪ 1+ is a small number,
▪ 2+ is a medium number, and
▪ 3+ is a large number of receptors.
ERs and Breast Cancer. Test results show ER+ in ~ 70% of breast cancer cases
(1) Estrogen binding to ER stimulates proliferation of mammary cells (increases cell division/DNA replication) leading to mutations.
(2) Estrogen metabolism may produce genotoxic waste.
- ER-α is associated with more differentiated tumors. ER-β involvement is controversial.
- Different versions of the ESR1 gene associated with different risks of developing breast cancer.
- Mainstream endocrine therapy. Anti-estrogen therapy works by blocking the hormone receptors, preventing them from signaling the cancer cells to grow.
• Some commonly used ER antagonists in breast tissue:
Selective estrogen receptor modulators (SERMS):
▪Tamoxifen - antagonist at breast /agonist at bone and uterus
▪Raloxifene (Evista) - antagonist at breast and uterus / agonist at bone
Selective estrogen receptor down-regulator (SERD):
▪Faslodex (chemical name: fulvestrant) - antagonistic in all tissues
• Some common aromatase inhibitor drugs (prevent conversion of androgens to estrogen) - only useful for postmenopausal women, because postmenopausal women get most of their estrogen from the conversion of androgens into estrogen by the aromatase enzyme, while premenopausal women get most of their estrogen directly from their ovaries.
▪Femora (chemical name: letrozole)
▪Aromasin (chemical name: exemestane)
▪Arimidex (chemical name: anastrozole)
▪PROGESTERONE is a natural aromatase inhibitor

Chronic low-level inflammation (CLII) involved in almost all health problems
"The medical kit of the future"
General electrotherapy health benefits. Used systemically and/or locally at specific problem areas of the body, its effective application has many benefits:
|Detoxification||Wellness / Healthy aging||Pain relief|
|Relief from insomnia||Immune system restoral||Anti-Inflammatory|
|Maximizes cellular energy production||Accelerated tissue /bone
|Muscle relaxation / rehabilitation||Increased blood oxygen
There are several reasonably affordable electrotherapy devices available for personal use. The following electrotherapies are those that have received a significant amount of positive feedback:
|Pulsed Electromagnetic Field (PEMF) therapy|
|Near Infrared (NIR) class 4 laser therapy|
Cranial Electrotherapy Stimulation (CES) applies specific frequency patterns to the head area, with the following benefits:
|Balances neurotransmitters||Relieves pain||Treats depression|
|Substance abuse withdrawal||Relieves insomnia||Relieve stress / anxiety|
