Nowadays, women are scared of breast cancer, since about 212,000 women were diagnosed with it in the USA in 2005. Pink ribbon is a women’s movement to find a cure for it.
As everybody is expecting a cure for it, I think find the most risky factor is more important. An ounce of prevention is worth a pound of cure.
Although doctors will tell you if you have a family history of breast caner, you are at high risk for it, but most women diagnosed with it are without a family history.
After analyzing tumor tissues, medical science classifies breast cancer to three types.
1. Hormone-positive type: About 60 % to 70% of patients are in this type. The tumor growth is driven by excess amounts of estrogen or progesterone. The treatment is tamoxifen which blocks the absorption of estrogen.
2. Her-2 gene mutation type: About 20 to 30 % of patients are in this type.
The aggressive tumors are caused by a mutation in the Her-2 gene. The treatment is Herceptin which blocks the genetic mutation.
3. Triple-negative tumors: About 10 % of patients are in this type. The tumor growth is not sensitive to hormones or Her-2. There is not much we can do about this type except surgery and radiation.
So, the genetic mutation is only counted to about 20 to 30 % of breast cancer. Most people have hormone-positive type.
Bingo! The No. 1 risk factor for breast cancer is excess amounts of hormones.
That makes perfect sense. Women can feel breast tender after taking some hormone pills because breast tissue is hormone sensitive.
No wonder breast cancer is epidemic toady. In fact, we live in the ocean of hormones, such as food produced by growth hormones, birth control pills, and hormone therapy.
