Receptors are proteins in or on cells that can attach to certain substances in the blood. Normal breast cells and some breast cancer cells have receptors that attach to the hormones estrogen and progesterone, and depend on these hormones to grow. The breast tissue estrogen receptor is both genetic and variable in the presence of chemotherapy and other medications. Breast cancer cells may have one, both, or none of these receptors. ER-positive: Breast cancers that have estrogen receptors are called ER-positive (or ER+) cancers. PR-positive: Breast cancers with progesterone receptors are called PR-positive (or PR+) cancers. Keeping these receptors from attaching to the hormones can help keep the cancer from growing and spreading. There are drugs that can be used to do this. Knowing the hormone receptor status of your cancer helps doctors decide how to treat it. If your cancer has one or both of these hormone receptors, hormone therapy drugs can be used to either lower estrogen levels or stop estrogen from acting on breast cancer cells. This kind of treatment is helpful for hormone receptor-positive breast cancers, but it doesn’t work on tumors that are hormone receptor-negative (both ER- and PR-negative).
It might depend on the cancer. Stage I breast cancer is the earliest stage of invasive breast cancer. At this stage, the cancer cells have spread beyond the original location and into the surrounding breast tissue. Because a stage I tumor is small, it may be difficult to detect. However, breast s....
Cancer is by definition abnormal growth of tissue which spreads and causes damage. The actual mechanism why and how it happens is the subject of a great deal of study but appears to involve small groups of cancer cells invading and breaking off in blood and lymph vessels and being carried along to d....
