Estrogen-dependent cancers include breast cancer and colorectal cancer. Studies of these cancers are discussed.
How does estrogen affect cancer?

Does cancer feed on estrogen?
Not all cancers are fueled by hormones. But a few types can be, such as: Breast cancer. Some types need estrogen and progesterone to grow.
