Hi,
The story so far: My Girlfriend found out back in February that she had Breast Cancer. Luckily she caught it early. It was Stage 1, Grade 2, less than 2 cm, they removed it, and some lymph nodes. The nodes were clear, as was a subsequent CT Scan. The lump also tested with top marks for hormone receptors, so Tamoxifen would be very effective. She was apparently a borderline case as far as Chemo was concerned, so having discussed it with her Oncologist and Surgeon she opted not to have Chemo. So she had a 3.5 week course of Radiotherapy, which she finished about 3 weeks ago, and then started Tamoxifen a few days later.
SO...... Within 2 weeks of starting Tamoxifen, she experienced severe pelvic pain, and ultimately stopped taking it. (She has had Endometriosis in the past, so wondered if it had enflamed this). According to her Gynecologist, this is because Tamoxifen doesn't stop estrogen production at all (contrary to what we thought!). It merely blocks it from the breast area in some way. So, your body then thinks you need to produce more and sends the Ovaries into overdrive producing it!
So, the Oncologist has now brought up the question of Ovary removal. - I have to say, the Oncologist seems to be quite gung-ho in wanting to do anything to attack the Cancer, and not particularly focusing on the side effects of any course of action. The Gynecologist is a bit more cautious though and is wanting to investigate whether it's really the best long term solution.
The other question is whether with persistance, the painful side effects of Tamoxifen would pass - if so, how soon (weeks/months if ever....) or whether Ovary removal is the better option.
She is also concerned about the prospect of weight gain following Ovary removal - so any experience of this or any other related issues please feel free to comment! I've also read some pretty scary statistics about Ovary removal in younger women (particularly below 38 / to an extent below 46) can increase chances of Dementia & cognitive function. Anyone have more info on this?
