Cancer can happen to anyone. It is not bound by age, gender, or ethnic group. Even so, among women, breastcancer is the most common form of the disease.
Women in the U.S. have a one in eight chance of developing invasive breast cancer during their lifetime. And the American Cancer Society estimates that more than 1 million women in the U.S. have breast cancer and don't know it.
Elyse Caplan remembers it well, that first conversation with her oncologist. She had just been diagnosed with stage IIB breast cancer, and they were discussing the game plan for treatment. If her oncologist mentioned "recurrence" -- the possibility that her cancer could return -- it was lost on her, she says.
"You sit through an hour-long appointment and take notes, but when the doctor says one thing that's very upsetting, you just freeze," she tells WebMD. "You're thinking, 'I'm going to lose my...
There are effective treatments for invasive breast cancer. It's important to recognize the signs of invasive breast cancer and to work closely with your doctor. Here's information you can use to help you have the best outcome with invasive breast cancer.
How does the anatomy of the breast relate to breast cancer?
The two most common types of invasive breast cancer include:
Invasive ductal carcinoma (IDC). With IDC, cancer cells start in a milk duct, break through the duct walls, and then invade fatty breast tissue. IDC can remain localized, which means it stays near the site where the tumor originated. Or the cancer cells may enter the bloodstream or lymphatic system and metastasize -- spread -- anywhere in the body. Invasive ductal carcinoma is the most common type of invasive breast cancer. It accounts for 80% of invasive cancers.
Infiltrating (invasive) lobular carcinoma (ILC). This cancer accounts for about 10% to 15% of invasive breast cancers. ILC starts in the lobules or milk glands. It then spreads in a way similar to IDC. With ILC, most women feel a mass or thickening instead of a breast lump.
There are mixed types of IDC and ILC and other less common types of invasive breast cancer.
