The stage of the cancer helps you and your doctor:. Breast cancer stage is usually expressed as a number on a scale of 0 through IV — with stage 0 describing non-invasive cancers that remain within their original location and stage IV describing invasive cancers that have spread outside the breast to other parts of the body.

Your pathology report will include information that is used to calculate the stage of the breast cancer — that is, whether it is limited to one area Bigass anal lezbian porno the breast, or it has spread to healthy tissues inside the breast or to other parts of the body.

Your doctor will begin to determine this during surgery to remove the cancer and look at one or more of the underarm lymph nodes, which is where breast cancer tends to travel first. He or she also may order additional blood tests or imaging tests if there is reason to believe the cancer might have Breast cancer stages and types beyond the breast. The AJCC is a group of cancer experts who oversee how cancer is classified and communicated. This is to ensure that all doctors and treatment facilities are describing cancer in a uniform way so that the treatment results of all people can be compared and understood.

In the past, stage number was calculated based on just three clinical characteristics, T, N, and M:. Numbers or letters after T, N, and M give more details about each characteristic. Higher numbers mean the cancer is more advanced. Jump to more detailed information about the TNM system. Adding information about tumor grade, hormone-receptor status, HER2 status, and possibly Oncotype DX test results has made determining the stage of a breast cancer more complex, but also more accurate.

So, a woman diagnosed with stage II disease that is triple-negative [estrogen-receptor-negative, progesterone-receptor-negative, and HER2-negative] will have a very different treatment plan than a woman diagnosed with stage II disease that is estrogen-receptor-positive. The staging guidelines now take into Breast cancer stages and types what doctors have been doing all along.

Medical oncologist Brian Wojciechowski, M. D, explains the T, N, and M parts of the staging system, how the new characteristics added to the staging Breast cancer stages and types affect a cancer's stage, and how a breast cancer that might have been IIIA in the past might now be IB. Breast cancer stages and types general, according to experts, the new staging system classifies triple-negative breast cancer estrogen-receptor-negative, progesterone-receptor-negative, and HER2-negative at Breast cancer stages and types higher stage and classifies most hormone-receptor-positive breast cancer at a lower stage.

The updated AJCC breast cancer staging guidelines have made determining the stage of a cancer a more complicated but accurate process. So, the characteristics of each stage below are somewhat generalized. Stage 0 is used to describe non-invasive breast cancers, such as DCIS ductal carcinoma in situ. In stage 0, there is no evidence of cancer cells or non-cancerous abnormal cells breaking out of the part of the breast in which they started, or getting through to or invading neighboring normal tissue.

Learn about what treatments you can generally expect for stage 0 in the Options by Cancer Stage: Stage 0 page in Planning Your Treatment. Stage I describes invasive breast Kyra sedgwick nude loverboy cancer cells are breaking through to or invading normal surrounding breast tissue Stage I is divided into subcategories known as IA and IB.

Still, if the cancer is estrogen-receptor-positive or progesterone-receptor-positive, it is likely to be classified as stage IA. Microscopic invasion is possible in stage I breast cancer. In microscopic invasion, the cancer cells have just started to invade the tissue outside the lining of the duct or lobule, but the invading Breast cancer stages and types cells can't measure more than 1 mm. Inflammatory breast cancer is considered at least stage IIIB.

Typical features of inflammatory breast cancer include:. Stage IV describes invasive breast cancer that has spread beyond the breast and nearby lymph nodes to other organs of the body, such as the lungs, distant lymph nodes, skin, bones, Breast cancer stages and types, or brain. The N lymph node involvement category describes whether or not the cancer has reached nearby lymph nodes:. The M metastasis category tells whether or not there is evidence that the cancer has traveled to other parts of the body:.
