Women with Breast Cancers That are Estrogen-Sensitive ____

Question

Women with breast cancers that are estrogen-sensitive ____.
A) become ill when taking prescription estrogen
B) can exacerbate their symptoms with only a small increase in estrogen levels
C) are in danger of faster growth of cancer cells in the presence of estrogen
D) will often experience cancer remission with increased uptake of estrogen
E) do not produce their own estrogen and must obtain it through diet or supplements

Accepted Answer

Women with estrogen-sensitive breast cancer have tumors that grow in response to the hormone estrogen. Therefore, an increase in estrogen levels can fuel the growth of cancer cells and make the cancer grow faster. This is why treatments such as hormonal therapy or surgery aim to reduce estrogen levels or block the action of estrogen in these women.
