Estrogen + breast cancer currently on chemo is it ok to drink a protein drink sometimes that has soy in it?

Probably. Much interest and research o0n phyto Estrogens in soy products. No convincing clinical studies to contra indicate soy in diet- especially if occasional use. Check to see the content of soy- if it is the predominant source for the protein and you are worried don't. If your chemo is anti estrogen or aromatase inhibitor, even less data.
Best to avoid excess. In general soy intake should be limited in women. There is really no science to guide us as to how much soy is too much. We do know that soy products act estrogen like in our bodies. Probably best to limit amount of soy products. Now if you only take one shake a day and don't consume other soy products you are definitely ok.

I had a healthy shake that had soy lecithin in it will that cause high estrogen and breast cancer I'm worried?

A Shake. One shake is not going to alter your risk for anything. Soy lecithin is not a harmful substance anyway and is not a risk factor for breast cancer or any other disease. For good health - Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Drink enough water daily, so that your urine is mostly colorless. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form. Practice safe sex. Get HPV vaccine. Read more...

What is estrogen receptor positive breast cancer?

Estrogen-SensitiveCA. Normal breast cells have estrogen receptors which are like locks that estrogen "keys" fit into. Many breast cancer cells also have these estrogen receptors, which is good for 2 reasons: (1)these cancers tend to be less aggressive (since they resemble normal breast cells), and; (2)"anti-estrogens" such as tamoxifen can be very effective chemotherapeutic agents for these cancers.

Feeds the cancer. Most breast cancers are estrogen receptor positive. The cancer cells have receptors that fit the estrogen molecule that a body produces. Think: a lock and key - when estrogen binds to the receptor the tumor cell is stimulated to grow and divide. Er+ tumors can be blocked by tamoxifen and Arimidex (anastrozole) (and others) that interfere with this pathway. Read more...
